Such a cold bed cycle is caused by the refrigerant evaporating from the indoor heat exchanger 5 to be taken away from the room, and the heat condensed by the refrigerant in the outdoor heat exchanger 3 is used to take the heat away from the room outdoors.

$ 21 pages 504559 V. Description of the invention (18) Out 'makes the room a cold room. Next, use the pressure shown in Figure 6 to pity you. B years turn you ^ 筮 A back to the line diagram to explain the actions of thirst quenching and transportation. X, the English characters shown in Figure 6 correspond to Xi and consecutive characters. During this dehumidification operation, the batch of English-language products not approved in the first figure is approved. The command from 1 /, the manufacturing device 4 2 makes the one-way valve of the control device 6 in the first stage. 2 becomes a closed bear. More first At this time, the high-temperature and high-pressure steam refrigerant corresponding to the air conditioner's wire 喆, ^: ⑻ operating pressure door 7 medium (point B). This π-pressure two-phase refrigerant is slightly decompressed in the first batch, and becomes a medium-pressure gas-liquid two-phase refrigerant. Here ^ :: 5, enter ((: point). Heat in the first room The intermediate-pressure turbulent liquid two-phase refrigerant system flowing into the exchanger 5 exchanges heat with the indoor air to condense (0 point). The gas-liquid two-phase two-phase quantity control device 6 flowing out of the first indoor heat exchanger 5 flows in. The younger brother W, because the two-way valve in the second flow control device Tan 6 is closed, the medium flows from the inlet pipe 8 of the second flow control device through the connection pipe 9 to the throttle device 11. In the throttling device n, the space 23 between the inlet pipe silencer space 19, the inlet side foam metal 20, the inlet side foam metal 20, and the hole 23 is reduced in pressure from the connection pipe 9. The low-pressure gas-liquid two-phase refrigerant passes through the space 24 between the hole 23 and the outlet 'side foamed metal 25 in sequence: the outlet-side foamed metal 25, the outlet-side silencing space 27, and the connecting pipe! 3 and flows into the second indoor heat exchanger 7 (point E). The thickness of the refrigerant flowing direction of the foamed metal set in the entrance and exit of this hole is based on the effect of reducing the flow sound and the ease of processing. It is good if it is 1 mm or more.

U4559

In Example 1, it is about 3 mm e x, and the inside diameter of the holes is about 2 mm. (2) The refrigerant flowing into the second indoor heat exchanger 7 is evacuated by room heat and latent heat. The refrigerant from the second indoor heat exchanger is returned to the compressor via the four-way valve 2 again. Since ^ 2 air is heated in the first indoor heat exchanger 5 and cooled and dehumidified in the second room to the device 7, the room temperature in the room can be prevented from being dehumidified and dehumidified, and the compressor is adjusted during this dehumidification operation 丨The number of rotations of the outdoor fan of the rotating frequency device 3, the control of the outdoor heat exchanger 3, the parent change, and the addition of the indoor air by the first indoor heat exchanger 5: the temperature of the blowout can be controlled in a wide range. In addition, by controlling the opening degree of the first flow control device 4 or the number of rotations of the indoor fan 41 to control the first room heat and the condensation temperature of the converter, the first indoor heat exchanger 5 can control the room; . The second flow rate control device 6 controls, for example, the pressure: the degree of superheating of the sucked refrigerant becomes it. "23, who": 1 for 9? The throttling process in the "knotting device U" is through the holes. The foamed metal with a porous permeating material is set at the entrance and exit sides of the holes 23. Spaces i 9 and 27 are provided on the upstream side of the metal foam 20 and downstream of the foam metal 25 on the outlet side, respectively, which can achieve a sound-absorbing effect, which can greatly reduce the conventional hole-type flow rate of the refrigerant flow that occurs when the gas-liquid two-phase refrigerant passes through. When the control device passes through the gas-liquid two-phase refrigerant, a large refrigerant flow sound occurs before and after the hole. Especially when the flow pattern of the gas-liquid two-phase refrigerant is a slag flow, the sound occurs upstream of the hole. The reason for this is in the gas-liquid two-phase cold =

504559 V. Description of the invention (20) When the dynamic pattern is melt flow, Fig. 8 shows the flow of the refrigerant. As shown in this figure, the vapor refrigerant flows intermittently, corresponding to the direction of flow, and the large vapor melts. When the slag or vapor bubbles pass from the hole flow path to the throttling part flow path, the vapor upstream of the hole flow path is dissolved or the vapor bubble collapses, causing vibration, or because the vapor refrigerant and the liquid refrigerant alternately pass through the hole. The speed is fast when the vapor refrigerant passes, and it becomes slower when the liquid refrigerant passes. Therefore, the pressure upstream of the throttle section also changes. Moreover, the conventional second flow control device 6 has one to four outlet flow paths at the outlet, and the refrigerant flow rate is fast. At the outlet part, it becomes a high-speed gas-liquid two-phase flow. The body or outlet flow path often vibrates and generates noise. In addition, turbulence or vortex occurs due to a high-speed gas-liquid two-phase jet at the exit portion, and jet noise is also increased. The gas-liquid two-phase refrigerant or liquid refrigerant flowing into the hole 23 of the throttling device u shown in FIG. 4 flows through the fine countless air holes of the foamed metal 20 on the inlet side, and flows and is uniform. For this reason, since the vapor slag (large bubbles) such as the gas-liquid intermittent flow of slag flows are changed from small bubbles, the flow state of the refrigerant is changed to a homogeneous gas-liquid two-phase flow (the vapor refrigerant and the liquid refrigerant are well mixed). State) 'In order for the vapor refrigerant and the liquid refrigerant to pass through the holes 2 3 at the same time, the speed of the refrigerant does not change, and the pressure does not change. In addition, the internal flow path system of the porous permeation material of the entrance-side foamed metal 20 is complicated. The internal pressure fluctuation system repeatedly changes a part of the thermal energy to change the pressure constant. Even if the pressure fluctuation occurs in the cavity 23, There is also an absorption effect, and its impact will not be transmitted upstream. Moreover, the high-speed gas-liquid two-phase jet flow downstream of the hole 23 is formed by the foamed metal 25 on the outlet side.

504559 V. Description of the invention (21) The flow velocity is fully decelerated, and the velocity distribution is also the same. There is no conflict between the two-phase jets of high-capacity gas and liquid on the wall, and no large vortices will occur, so the jet noise will also be Get smaller. More importantly, since the inlet silencer space 19 is provided on the inlet side of the throttle device 11, it is possible to reduce the low-frequency pressure fluctuation that cannot be suppressed by the foamed metal 20 on the inlet side. Similarly, since the outlet silencer space 27 is also provided at the outlet side of the throttle device 11, pressure fluctuations at low frequencies that cannot be suppressed by the foamed metal 25 at the outlet side can be reduced. The porous permeable material 20 is arranged substantially linearly in accordance with the refrigerant flow direction in the main body 61, and is arranged in a position approximately linearly corresponding to the inlet interior space 19 and the outlet interior space 27. Therefore, the flow path between the porous permeable material 20 and the hole 23 having the throttling passage is slightly linear, and the structure is simple and resistant to becoming smaller. Therefore, the refrigerant flows through the porous permeable material 20 The system becomes a homogeneous gas-liquid two-phase flow (a state where the vapor refrigerant and the liquid refrigerant are well mixed), and more importantly, the refrigerant system maintains a state of the homogeneous gas-edge two-phase flow (a state where the vapor refrigerant and the liquid refrigerant are well mixed). It is possible to pass through the throttling passage (holes). 23 The speed of the refrigerant does not change, the pressure does not change, and noise is not easy to occur. In addition, the porous permeable material 20 is brought into contact with the position determining protrusion 61b, and then the porous permeable material 20 is inserted between the position determining protrusions 61 by a press-in element 62, and then pressed. The insertion element 62 is fixed to the body 61 by press-fitting, firing-fitting, welding, or the like. Therefore, the determination of the position of the porous permeable material 20 during assembly is performed simply and surely. Therefore, a low-cost throttling device with shorter assembly time and improved reliability can be obtained. Moreover, since the structure is simple, a low-cost throttling device can be obtained. Again, available

V. Description of the invention (22) In the conventional device, a low-cost throttling device that does not require countermeasures such as rolling the sound shielding material or the vibration damping material around the device is required. For this reason, countermeasures such as surrounding the sound-shielding material, which are necessary in the conventional device, are also unnecessary, and the cost is reduced, and the recycling performance of the desired device is also improved. In addition, the problem of the sound of refrigerant flowing due to the above two-phase liquid refrigerant is not limited to the following: Among the general related problems such as the second ring and the like, this example is: ς This is widely applicable to the cold cycle and so on. It can be obtained that the flow characteristics of the second flow control mechanism 6 during the same rotation = the relationship between the loss) is adjustable by adjusting the diameter of the hole 23 or the length of the & road that the medium passes and the number of holes. That is to say, σy, when there is a small pressure loss flow of the refrigerant flow, increase the hole = 22 =, shorten the flow path length, it is better to use a plurality of holes. Again ’:

In the case where the St cooling amount flows with a large pressure loss, the hole diameter or flow path timing used in the flow part of the small hole ί is optimally designed. , (The opening effect is mainly due to the use of ceramics for the components of the machine, and the porous perforated stove metal used at the exit side, "also in the case of 1 genera." However, k ... metal foam resin and metal mesh It can also be obtained that a bypass flow path (through

21, 2 6, the entrance-side foamed metal 20 and the exit-side foamed metal 25 are caused by the foreign matter in the A beam cycle to block the mesh, which can prevent the performance of the mesh from being reduced. More importantly, since the space 22 between the entrance-side foamed metal 20 and the hole 23 and the hole 23 and the exit-side foamed metal 25 are provided, most of the foamed metal becomes a refrigerant. The flow path can maintain the function as a throttling device, and since the reliability as a throttling device is fully maintained, it can also provide sufficient maintenance as the air conditioner. In this example, the shape of a bypass flow path in a cylindrical shape is described in the example, but it is not limited to this. The shape of the bypass flow path shown in Fig. 12 or Fig. 13 is an undercut shape or a plurality of circles. The cylindrical bypass flow path can also achieve the same effect. Fig. 9 shows the frequency characteristics of the noise generated by the conventional throttling device and the measurement results of the frequency characteristics of the noise of the throttling device of this embodiment. In the figure, the horizontal axis system frequency [Hz] and the vertical axis system sound pressure (SPL) [dBA]. The dotted line indicates the second flow control device of this embodiment, and the solid line indicates the conventional second flow control device. In this embodiment, compared with the conventional example, it can be seen that the sound pressure level is reduced in the entire frequency range. In particular, a significant reduction in the range of 2000 to 7000 z that can be clearly heard in human ears can be obtained.

Next, the operation control method of the air-conditioning apparatus according to this embodiment will be described. The air conditioner 'is a temperature and humidity environment set by the occupants living in the room'. For example, the set temperature and humidity are set when the air conditioner is operating. In addition, the set temperature and the set humidity can be directly input by the occupant from the remote control 43 of the indoor unit.

The refrigerant of the machine can stabilize the cold oil in this embodiment under low noise, but when foreign matter in the refrigeration cycle is present, in the case of the aforementioned foamed metal, at The reliability of the oil is increased. Engine oils are made of refrigerant-insoluble alkylbenzenes. Insoluble foreign substances that are insoluble in refrigerants and cold-bundled engine oil foreign substances are difficult to adhere to porous materials. ≫ The effect of the foreign matter in the foamed metal corresponds to the adhesion of the foamed metal in the throttling part.

The high-pressure liquid refrigerant or gas-liquid two-phase refrigerant flows into the second flow control device 6 into the second flow control valve 6, because it is a valve body of the two-way valve 12 as shown in FIG. 3 (b). 1 7 is tightly connected to the valve seat 1 8 and flows through the pipe 1 and 3 in the throttling position 1 1 to flow in and reduces pressure and expands in the hole 23 to become a low-pressure gas-liquid two-phase cooling.

Thus, in this embodiment, since the second flow control valve is used as the structure for inserting the throttling device 11 and the hole 23 as the foamed metal, the dehumidification operation becomes possible on the warming day, and the dehumidification operation during the warming room is prevented. The occurrence of refrigerant flowing sound can realize a comfortable space in both temperature and humidity environment and noise surface. two

Next, an example of a specific greenhouse operation control method for an air conditioner will be described. In this air conditioner, as described in FIG. 7, the set temperature and the set humidity, and the temperature and humidity of the intake air are input. This air conditioner is operated for a predetermined period of time when the greenhouse is blown out at a high temperature, for example, for 5 minutes without operation, and then transferred to a normal greenhouse operation. Thereafter, in accordance with the temperature deviation and humidity deviation of the room, the control is switched between the normal greenhouse operation and the greenhouse dehumidification operation. ~

When the greenhouse operation is started, the second flow control valve 6 throttles the valve body 17 of the two-way valve 12 and the valve seat 18 as shown in Fig. 3 (b) to start the compressor 1. At this time, since the cooling and dehumidifying capacity of the first indoor heat exchanger 5 becomes 0, the number of fan rotations of the outdoor heat exchanger 3 or the opening degree of the first flow control valve 4 is adjusted, etc., the first indoor heat exchanger 5 The steaming and temperature of 5 are controlled to be equal to the temperature of the intake air. After 5 minutes have elapsed since the compressor was started, the second flow control valve is transferred to a normal greenhouse operation when the second flow control valve is opened as shown in Fig. 3 (a). At this time, the rotation frequency of the compressor 1, the number of rotations of the indoor fan, and the number of rotations of the outdoor fan are adjusted and controlled so that the temperature deviation becomes zero or within a predetermined value. Due to the normal operation of the greenhouse, the temperature deviation becomes zero or a predetermined value

The stagnant part of the refrigerant flows in the convex flow. The foreign material system can be foamed on the stagnate side 20, and can be further improved. It is explained that the stagnant part is formed here, for example, a concave groove or the like. The lumps 28 are formed in front and back of the 'Cold' part to stay inside the circulation, preventing the reliability of the air conditioner from adhering to the person σ. In the case of the convex block of the present embodiment, 'However, it is not limited to the case where a flow stagnation part is formed.

The average pore size of the filter screen is set ^ wide = side foam metal 20 and outlet side foam The average pore diameter of the metal 25 is small. ——Compared to FIG. 10, a convex block 28 is formed in the inlet silencing space. In the embodiment, the inlet silencing space 9 and the outlet silencing space 27 are filtered by the Internet. In the aspect of the net 29, it is possible to more reliably prevent foreign matter from adhering to the foamed metal 20 at the inlet side in the refrigerant cycle, so that a second flow control device with more reliability can be obtained, and an air conditioner with high reliability can be realized. Jian

In the above description, the case where R4oA is used as the refrigerant of the air conditioner is explained. R410A is an HFC refrigerant, which does not damage the ozone layer and is suitable for protecting the global environment. Compared with 1 ^ 2, which is commonly used as cold, the refrigerant has a higher vapor density and a slower flow rate. The loss is small, so the ventilation pore diameter of the porous body used in the throttling device of the second flow control device 6 can be reduced, and a further refrigerant flowing sound can be obtained

504559 V. Description of the invention (31) Low effect refrigerant. More importantly, the refrigerant used as the air conditioner is not limited to R407C, R404A, and R507A among R410A'HFC refrigerants. From the viewpoint of preventing global warming, R32 alone, R1 52a alone, or a mixed refrigerant such as R32 / R1 34a among HFc-based refrigerants having a small global warming coefficient may be used. HC-based refrigerants such as 'propane or butane' isobutane, natural refrigerants such as ammonia, carbon dioxide, and ether, and mixed refrigerants thereof may also be used. In particular, propane or butane, isobutane, and these mixed refrigerants have a smaller operating pressure than R41 0A, a smaller pressure difference between condensation pressure and evaporation pressure, and the inner diameter of the pores can be increased. Improved even more. In addition, the two-way valve has three effects. The side-by-side heat exchanger of the flow part is used to reduce the flow rate of the generator and the flow rate. The combination of porous pores and air bubbles passing through the holes is a combination of the valve and the valve. There is a description of the structure caused by gas bleed, but in the second occasion, the freezing circuit of the piping force on the side of the flow path is set, the steam valve and the sub-L hole are liquid, and the second is not a limited flow control three-way, other than the valve The branching method can make the device series sender to connect the refrigerant in the flow path in parallel, stop the refrigerant to set a two-way valve, so that the device can also be used. The method of using the door, the flow path system maintains the refrigerant circuit, and is bypassed by the air refrigerant . The multi-directional valve can be used to prevent the occurrence of sound of refrigerant vapor flowing through the throttling of the refrigerant flow, which is generated by the compression-type connection, and it can be used to adjust the load condition in the second room and the condensation cooling.

504559 V. Description of the invention (32) Sound, more importantly, it can get the effect of preventing clogging of foreign objects in the circulation. The refrigeration cycle device of the present invention includes holes in the throttling flow path device, so the effect of stably adjusting the refrigerant flow rate can be obtained. In addition, at least one of the upstream and downstream directions of the flow direction of the refrigerant in the hole includes a porous permeate. Therefore, the vapor slag or the refrigerant bubbles are miniaturized, so that the gas-liquid two-phase refrigerant can reduce the flow of the refrigerant that occurs in the upstream of the hole. Sound or jet effects. In addition, the space between the hole and the porous permeation material is provided to prevent the clogging of the orifice of the throttling device ...

The anti-corrosive material is provided with at least one diameter of 10 () " above: through; holes in: ; = Beton hole which prevents the clogging of passing material and enhances the reliability. Therefore, the refrigerating cycle device of the present invention can be prevented from passing through the upstream of the material through the hole of the material. At least one of the porous swimmers placed upstream upstream includes the porous 222 downstream of the porous permeation material below the porous perforation material, so that it is possible to prevent the upstream side from being damaged. In the porous plug ’, the reliability is improved. Stop on the upstream side: porous. Since the stagnation portion is included, a preventable effect can be obtained. In addition, in hole 2, blocking is more important to reduce the occurrence on the upstream or downstream side of the hole;

2148-3761-Pf.ptd Page 36 Holes are installed downstream of the hole; Material: Porosity: Upstream of the material and there is space, so two holes can pass through at least the downstream of the material-Fang Baohong 504559 V. Description of the invention (33) The effect of media flowing sound. In addition, the refrigerant is made of a non-azeotropic mixed refrigerant, so even if the phase state of the refrigerant is changed in various states such as liquid, gaseous, and two-phase, the flow resistance of the refrigerant can be stably controlled with low noise and passed. The effect of the freeze cycle. Since the refrigerant is a refrigerant having a larger vapor density than the R22 refrigerant, the effect of miniaturizing the throttling device can be obtained. In addition, since the refrigerant system is made of a hydrocarbon-based refrigerant, it is possible to obtain an effect that the bore diameter of the throttle portion can be increased and reliability can be improved. In addition, since the multi-directional valve is closed during the reheat dehumidification operation, the effect of dehumidifying the room without lowering the room temperature can be obtained. In addition, since the refrigerating machine oil that is easily soluble in the refrigerant is used, even in the cycle where the refrigerating machine oil that is insoluble in the refrigerant is dissolved, the foreign matter can be washed by the refrigerating machine oil even if it adheres to the porous permeable material, thereby improving the reliability corresponding to the clogging of the holes. 2 Fruit. In addition, refrigerating machine oil that is hardly soluble in refrigerant is used, so when the compressor stops oil from adhering to the porous permeate material, when the compressor starts ^ the refrigerant can be washed away by the refrigerant; to improve the reliability of the engine oil = Regulating device system Including the connection compressor, outdoor heat exchange p / guari control device, the first indoor heat exchanger, the Wang-Fadan know: the refrigeration cycle of the device, the second indoor heat exchanger, "π = the second flow control device is The multi-directional valve will be: 2 sets of porous perforated materials in which the moving direction is connected to the second, and the occurrence of the collapse of refrigerant vapor or refrigerant bubbles in the refrigerant flow to prevent the occurrence of sound, reduce noise, and more The effect of heavy squares to stop the refrigerant from blocking the flow of the refrigerant.

Therefore, the hole element 6 8 can be easily inserted into the body 6 9 even if it is not press-fitted or fire-fitted, so that the assembly is improved, and the manufacturing time of the throttle device is shortened. The same effect can be obtained by air-tightly joining the cover 65 to one end of the main body 71 as shown in Figs. 42 and 43. In this structure, there is one fluid (refrigerant) inlet and one outlet. However, if one or more inlets and outlets have been described, it is also possible to use two or more. It is also possible to arrange the inlet and outlet in the reverse direction. As in the foregoing description, the porous permeation material 20 is not only a foamed metal, but a porous metal that sinters a metal powder or a porous ceramic material.

504559 V. Description of the invention (48) The same effect can also be obtained by using materials' or metal meshes, metal meshes with overlapping numbers, sintered metal meshes with overlapping numbers and sintering, and laminated metal meshes. The porous permeable material 20 may not be disc-shaped, and the same effect can be obtained in a polygonal shape. Further, the hole element 68 and the main body 71 may have a polygonal cylindrical shape instead of a cylindrical shape, and the same effect can be obtained. As described above, a predetermined gap 6 1 c ′ is provided between the porous permeable material 20 and the pores 23 and 68 a. However, as described above, the predetermined gap 6 丨 c may not be provided. In this case, it is not necessary to provide the position-determining projections 6 2 b, so that a low-cost throttling device can be obtained. 44, 45, 46, 47, and 48 are sectional views of a throttle device of another structure, and a filter 72 is provided to the above-mentioned throttle device. Fig. 49, Fig. 50, Fig. 51, and Fig. 52 are perspective views of the filter 72. Note that descriptions of the same elements with the same symbols are omitted. In addition, the result is the same as the refrigerant circuit described above. 7 2 series filters, such as the 49th, the network cable 72a is fixed, for example, by a ring-shaped fixing element 72b, and the inner wall of the pressing element 62 of the throttle device U shown in FIG. 44 is fixed by pressing. Alas. The mesh line 72a of the filter 72 is formed of a metal mesh or the like, and has a smaller diameter than the vent holes of the porous permeable material 20. The circuit configuration of the refrigerating cycle is the same as that described above. However, when foreign matter occurs in the fluid (refrigerant) that flows through the cold cycle, the filter 72 is used to pass the foreign matter with a large pore diameter. Keep,: Do not reach the porous permeation material 20. On the other hand, when the foreign material with a smaller air pore size than the filter "is passed through the filter? 2, and the day is porous permeation material 20, but the porous permeation material 20 Vents for material 20

504559 V. Description of the invention (49) The diameter is larger than the vent hole diameter of the network cable 72a of the filter 72, so it also passes through the porous material 20. For this reason, foreign matter is not blocked in the porous permeable material, and the blocking resistance is improved. In addition, it is possible to prevent a decrease in performance due to an increase in pressure loss caused by the f plug of the porous permeable material 20, and to obtain a highly reliable throttling device. In addition, when the filter 72 is provided between the porous permeable material 70 and the throttling passage 23 having $ holes, even when the flow direction is used in the reverse direction, foreign matter will not be blocked and blocked in the porous permeable material 20 Endurance

Also, 'increasing the surface area of the network cable 72a as shown in FIG. 50 and fixing the mouth of the filter 72 and the element 72b as shown in FIG. 45 are fixed on the inner wall of the pressing element 62 by pressing or the like.' The amount of foreign matter maintained is more important to improve the resistance to clogging. In addition, as shown in FIG. 5 丨, is the filter 72 provided with a fixed extension part on the fixing element 72b fixed to the network cable 72a? 2c, as shown in the figure, sandwiching the fixed extension 72c 'between the press-in element 62 and the porous permeable material 20 can obtain the same effect as the structure of the fixed filter 72. In addition, to increase the surface area of the filter 72 as shown in FIG. 52, it is more important to provide the shape of the fixed extension 72c in the fixed element 72b, as shown in the press-in element of FIG. 47 and the porous permeable material 20. By sandwiching the fixed extension 72c, the same effect as that of the structure of the fixed filter 72 can be obtained.

σ There is one filter 7 2, but a plurality of filters may be provided. The filter 72 is provided only on the side of the throttle passage 23, but may be provided on both sides of the throttle passage 23 as shown in FIG. 48. In addition, the filter 72 of this embodiment is applicable to any of the throttling devices described so far, and a throttling device and a refrigerating cycle device having improved blocking resistance and high reliability can be obtained.

504559

In addition, a metal mesh is used as a constituent element of the filter 72. However, a foamed metal, a sintered metal of sintered metal powder, or a porous porous material of ceramics, a plurality of overlapping metal meshes, and a plurality of sintered metal sintered by overlapping metal meshes are used. Nets and laminated metal nets can also achieve the same effect.

The porous permeable material 20 described above may be provided with through holes as shown in Figs. 53 and 54. Figures 53 and 54 are perspective views of a porous permeable material. In the figure, 20 series of porous permeable materials and 21 series of through-holes are provided at positions shifted from the axial position of the throttle passage 23. Corresponding to the flow direction of the porous permeable material 20 from the throttle passage 23, 1 mm to 3 mm (above the inner diameter of the hole) is provided through the hole 21, the flow noise reduction function will not be lost, and clogging resistance can be improved. High blocking device. The through-hole 21 is offset by the throttle passage 23 corresponding to the flow direction of the fluid (refrigerant). Since the porous passage material 20 exists in the portion where the throttle passage 23 flows easily, the flow noise is not reduced. This function can improve the resistance to blockage of porous permeate material 20. In addition, since the porosity of the porous permeation material is large and the fluid (refrigerant) is not concentrated in the through holes 2, the porous permeation material 20 does not have the above-mentioned function. In addition, as shown in Fig. 54, two through holes 21 are provided. However, the same effect can be obtained by providing three or more through holes.

In the above description, the case where R 41 0 A is used as a refrigerant for a fluid used in a cold beam circulation device is explained. r & 1 〇A series HFC 糸 Refrigerant is 'refrigerant suitable for protecting the global environment without destroying the ozone layer', and compared with R22, which is a conventionally used refrigerant, the refrigerant has a smaller pressure loss, so it can be used more efficiently.

The more important 疋 'is used as the refrigerant used in the refrigeration cycle device, and is not limited to R410a or R0407c or R507A among R410A' HFC-based refrigerants. From the viewpoint of preventing global warming, R32 alone, R152a alone, or R32 / R134a among HFC-based refrigerants with a global warming coefficient = may be a refrigerant. In addition, HC-based refrigerants such as propane, butane, and isobutane, or natural-based refrigerants such as ammonia, carbon dioxide, and ether, and mixed refrigerants thereof may be used.) Furthermore, the throttling device of the present invention is not only a refrigeration and air-conditioning device. However, the system can also be applied to an evaporator and a condenser that are integrally formed, and a dehumidifier or a refrigeration cycle with a heat exchanger that is used to distinguish between the interiors is a refrigerator or window air conditioner that is only completed indoors. In addition, the throttling device of the present invention is not limited to a refrigeration cycle device, and may be used if a throttling device is necessary. In addition, the flow system used in the throttling device can also use any of the above-mentioned flow systems, with the flow path configuration of the space headquarters, and the fluid on the fixed side and the flow and the noise through the throttling are not the same. "... 口" 柯 田There are two throttling channels that are arranged in a line corresponding to the flow direction of the fluid, the two spaces that connect the interior of the body to the outer three of the body, and the two spaces that correspond to the interior of the body. Straight line = 'porous permeation material' provided in at least one of the two spaces inside the body to separate the throttle passage side, so the liquid flow system becomes a homogeneous gas-liquid two-phase flow. The speed does not change, the pressure does not change, and it is easy to occur. The present invention includes a throttling passage with holes in the interior to communicate 504559 V. Description of the invention (52) The connection has a body corresponding to the interval and a corresponding direction. The position between the direction of the space between the fluid flow and the opposing side and the throttle path determines the communication with the outside, and the opposing side is pressed in and the position is determined to position the protruding protrusion through the material. The throttling device and the gap of the present invention can be effectively used. For the hole blocked by foreign matter and the porous material can be divided into two space channels and the porous energy can be obtained. The site is designed so that it will not lose the financial property of reduced clogging. Also, "a setting where at least the flow passes in a space where the flow direction of the throttling fluid is aligned in a straight line" is provided by at least one open porous permeable material, which is porous The position of the permeation determines the flow path of the protrusion and the perforated element, and the position of the perforated perforated element. The position is determined, so the fixing system can be simply and surely installed. The perforation through the hole and the permeation through the porous material Even if the foreign matter mixed in the fluid is improved, the high-reliability material is integrated into a joint and the shape of the material fixed in the body is improved in advance. There is a more restrictive path outside the axis of the highly reliable direction. The function of the diameter of the flow noise, the throttling between a space, the porous material and the The throttling flow path is connected when the fluid of the material is assembled, so the part of the throttle device surface of the state body has a large diameter to enhance the flow path of the two empty fluids. The side space mass penetrates the material fluid. When the flow-passing side space throttling passage material abuts, the porous permeation time is shortened when there is a large passage area between the porous permeation time shortening. Also, the hole can be integrated inside the body to restrict the combination of throttling. Also, Compared with the porous through-holes, the part between the passage of the porous material and the porous material is connected.

V. Description of the invention (53) The diameter of the porous permeation material and 20 vent holes is blocked, and the plugged endurance plug increases the pressure loss. In addition, corresponding to the above, the throttling device of the heat exchanger can be connected, processed, and the assembly time can be slightly at right angles in a direction in the direction of the space. The flow direction in the interior is slightly straight. The two spaces inside correspond to the aforementioned body inside the aforementioned body, and the passage side and the aforementioned flow path device are arranged in the structure and indoors, so the vibrating material in the throttling device has a low cost. The network cable located between the noise flow paths is improved in the porous, and can prevent the flow path that can be piped from being added, and the piping at one inlet and the outlet is therefore not intentionally concentrated into a shortened throttling device. It is also possible to use any piping such as the fluid in the body of the body, and the east circulation device, and a flow device can be obtained. A two-space heat-dissipating heat-exchanging device known as a multi-cold-bead circulation device, which is connected to the interior of the main body and connected to the interior of the main body through a throttling path, is necessary. It is necessary to wind up the surrounding refrigeration equipment. Porous materials are more porous, and foreign materials that do not penetrate porous materials are highly reliable. There are two throttling spaces. You can set up two or more of them. You can also use one of them. The flow direction of the flow path is slightly parallel or any combination of all devices can be easily combined to form a body corresponding to the refrigerant, a flow path external to the body, and fixed in a straight line. A space that passes the aforementioned throttle material through the vicinity of the throttle of the material or the refrigerant circuit = will not require sound-shielding materials or systems, but will be available and will include the flow direction of the media connected by the throttle channel inside The two offices arranged in a straight line have a body corresponding to the cold one and two rooms,

Description of the invention (54) _ At least one of the two spaces is set with the flow of refrigerant, at least _ the space will pass through the throttling path to the side to allow the refrigerant to pass through, and the porous material The open position determines the protrusion and the flow path which has the vacancy determined on the opposite side. The porous permeation material extends from the throttle path and the section of the indentation element that is provided by the protrusion pressing. There is no need to set a filter in the vicinity of the refrigerant or in the refrigerant circuit and in the refrigerant circuit that constitutes the cold-beam circulation. Instead, a refrigeration cycle device that can be: f and other. ] Low-cost and low-noise *: In the adjustment device, 'Includes an indoor unit with a heat exchanger arranged inside the cabinet to replace the indoor hot rolling heat exchanger and a control device on the side of the converter inside the cabinet.

In addition, it includes a heat exchanger that is arranged in the casing and exchanges the heat of the indoor air. The throttling device is between the heat exchanger and the control device. : It can be arranged between, so the throttling device is a refrigeration cycle device with low noise, no sound insulation material, etc., or it can be installed at any position. It can obtain the throttling device with a large degree of freedom and low cost.

The average diameter of the air holes (the surface of the porous body and the pores inside the fluid) is 40 micron 2 sintered metal (hereinafter referred to as porous body 152 or Sintered metal).

Description of the invention (57) The groove 153 of the body 150 is connected to the pipe 9 connected to the second flow control device fish 5 and to the second indoor heat exchanger? Due to the cooling force loss through this second flow control device, there is no reduction in cooling room capacity or efficiency. In addition, if the refrigerant in the f compressor 1 is sucked into the refrigerant, the cold r =; r the two converters 5 are taken away from the refrigerant ^ and let it be released outdoors; and its-the pressure shown in Figure 6- Start action. It should be noted that the English word shown in Fig. 6 should be used during wet operation.

The air vent is 40 micrometers; the in-range / 'changer 7 flows in. This main cardia body ^? Method A, Ke, 丄 A w々 姝, and the heat exchange state in the first room 7 = painful care. 2. The refrigerant flowing in the second indoor heat exchanger 7 takes away the room. Low: 蒗 2: 5 and latent heat to evaporate. The inner space sent by the second indoor heat exchanger: The "four-way" valve 2 is returned to the compressor. Because the chamber wV is completely heated, the crystal-to-internal heat exchanger 5 is heated and dehumidified in the second room heat exchange cold section. To prevent the room temperature from falling and dehumidify. During the dehumidification operation, adjust the rotation frequency of the compressor 1 or the room: the number of rotation of the heat fan, and the heat exchange of the outdoor heat exchanger 3. The amount of heating of the indoor heat exchanger 5 to the indoor air can be widened = Πΐ degrees ... which controls the first flow control device 4

Hi :: The number of fan rotations to control the condensation of the first indoor heat exchanger: 1 ': The superheat control of the indoor air heating is controlled by the second indoor heat exchanger 5; the 6-series control is, for example, the compressor sucks the refrigerant. The middle main valve body 150 is made of sintered metal, which can greatly reduce the refrigerant flow sound when the gas passes. Conventional holes Acoustic-packed gas-liquid two-phase refrigerant passes when a large refrigerant flow sounds. Especially in the case of the gas-liquid two-phase refrigerant whose flow pattern is dissolution flow 504559 V. Description of Invention (59), it is known that a large refrigerant flow sound will occur. This is because, as mentioned above, in the case where the flow pattern of the gas-liquid two-phase refrigerant is a slag flow, the vapor refrigerant corresponding to the flow direction flows intermittently, and large vapor slag or vapor bubbles flow from the throttle section flow path When passing through the flow path of the throttling section, the steam upstream of the throttling section's flow path collapses or the vapor bubbles collapse, causing vibration, or because the vapor refrigerant and the liquid refrigerant pass through the throttling section alternately. Faster, slower as the liquid refrigerant passes, so the pressure changes accordingly. Also, the conventional second flow control device 6 has one to four outlet flow paths at the outlet. The refrigerant has a fast flow rate, and vortices are generated at the outlet, so that jet noise becomes large. ▲ The second flow control shown in Fig. 55. The gas-liquid two-phase refrigerant or liquid refrigerant in Pei Chi 6 is decompressed by the flow of minute and numerous pores in the main valve body made of sintered metal. For this reason, vapor slag or vapor bubbles do not collapse. In addition, since the vapor refrigerant and the liquid refrigerant pass through the holes 23 at the same time, the speed change of the refrigerant does not occur, and the pressure does not change. There is one known flow path in the hole. However, the flow path inside the sintered metal is complicated and its internal pressure is reduced. Fluctuations in the internal flow rate of a porous system of sintered metal are the effects of pressure to change a part of the thermal energy repeatedly to make the pressure constant. The general sound-absorbing effect mentioned in the above is a structure that considers noise reduction. In addition, since the flow velocity of the refrigerant inside the pore body is reduced to a constant value for a minute, the vortex does not occur in the flow at the outlet of the throttle section, and the jet noise is also reduced. + ί Therefore, in the conventional device, it is necessary to take countermeasures such as rolling the sound-shielding material or the vibration-controlling material f around the throttle device, and the cost is not required. It is important to improve the recyclability of the air-conditioning device. . X, the above

The reason is that the problem of refrigerant flowing sound is not limited to general problems such as the refrigeration cycle of air conditioners. This embodiment is widely applicable to general refrigeration cycles and other general problems. The clearance rate (medium flow path (plus), the amount is large (decreased), so that the most suitable time to use is the same (will be in the molten foam tree and the entrance of the entrance but driven by the reservoir and other devices caused by the system. The dehumidification flow of the room and the pressure per unit of the porous body in the small large porous space are arranged in combination with the porous porous body, and the melting point of the main metal powder is greased. Due to the performance of the main valve moving motor, the pressure loss during operation The diameter or volume of the pressure loss body has a large element loss rate and a low flow element rate, and a ventimeter with a small flow rate. The relationship between the flow rate characteristics of the valve body and the closed second temperature control device 6 is lost. The main valve body 150 can adjust the length of the flow path through which the refrigerant passes and the void space volume of the porous body). That is, in the case of cold loss flow, increase the vent hole of the porous body) ' Shorten the length of the flow path (It is better to shorten the porous body of the valve body. On the other hand, when the refrigerant flows, 'reduce the vent diameter of the porous body ^' and increase the length of the flow path (It is better to lengthen the porous body of the valve body. In this case Main valve body aperture_The shape of the valve body is a porous body element used in the design of the machine. It is made of sintered gold and gold powder in a mold and press-molded, and then sintered to make it) or ceramic, foamed metal, main The valve body 150 can be driven by a stepper motor 丨 5}. The throttle body 150 is blocked by holes in the circulation caused by foreign objects. Moving the new surface to the inlet can prevent the holes from being blocked. More importantly Yes, the main valve body is fully porous

Page 64 ^ U4559

V. Description of the invention (61) The entrance part causes blockage of the eyes, but because the groove is provided in the main valve body 150, the position of the part containing the groove in the throttle inlet can be maintained by the motor to move the main valve body 150. For the function of the throttling device, since 3 = reliability of the throttling device, it can also provide sufficient maintenance of the reliability of the knife as a two-adjustment device. Next, the description of the operation control device of the air-conditioning device according to this embodiment is to set the preferences of the occupants living in the room: temperature and humidity, for example, the set temperature and set humidity are set when the air-conditioning device is running. ί The set temperature and humidity are set by the occupants from the indoor unit 5 remotely. It is also possible to directly input the set values separately. Also, for people who are afraid of heat, for people who are afraid of ▽ or for children, elderly, etc. iC temperature and humidity optimum value table, only by the object of residence: the person to translate: ί can. In the indoor unit 34, sensors for detecting the temperature of the indoor unit are provided. The sensors detect the temperature of the intake air of the indoor unit. Π, Liang 5, and w are adjusted, and the difference between the set temperature and the current indoor suction air L is calculated as the temperature deviation, and the difference between the set humidity and the current indoor suction 々f degree is used as the humidity deviation. Finally, In order to make these deviations 0 or less, the rotation frequency of the compressor 1 of the air-conditioning device is controlled. When ^, ^,,,, / W is opened, and the second flow control valve 6 is opened and closed. . When the humidity deviation is controlled within 0 or a predetermined value, the snoring deviation is given priority over the humidity deviation and the control / pulsation of the air conditioning device is implemented. That is, when the air conditioning device starts, the temperature deviation and humidity Bo

In addition, the second flow control valve 6 is shown in FIG. 5 7 (b). The piping 9 and piping 13 are connected with a large opening area. Therefore, there is almost no refrigerant pressure loss when passing through the valve, and there is no reduction in heating capacity or efficiency by the pressure loss.

The air heat exchange and the grave I medium are returned to the compressor 1 again through the first flow rate when the low-pressure steam sent from the external heat exchanger 3 is cold-rotated. The opening degree 'of the outlet Λ of the heat exchanger 3 for ordinary house heating is such that, for example, the outdoor operation corresponds to the following operation during the wet operation. μ ^ Central literary, state-of-the-art, in addition to the flow control of the greenhouse, the door 6 series such as ^ 7 room = wet operation, the control unit instructs the second and second flow control device to be changed into the main valve body when the first picture (a) = shown The end of 150 is the position of the pipe 9 connected to the inner heat exchanger 5 from the first to the inner heat exchanger 5 = one, and the position of the pipe 13 connected to the heat exchanger 7 of the inner heat. At this time, the 'compressor 1 sent high to the mouth position to the valve 2 and the 7-media steam rolling system in the same-room dish condensed by four exchanges (inner heart =: 7 two two') and indoor air ... Two flow control devices 6 = ㈣ refrigerant or gas-liquid: phase cooling medium 15. The first system is in the flow volume-control gate 6 'because the main valve body 150 is connected to the first as shown in Figure 57 (a) ^ I The end of the control device is the same as that of the first indoor unit and is connected to the second indoor heat exchanger 7. The second unit is connected to the vent hole in the cold valve body 150 into which the valve flows, and is located in the first official unit. The vent hole of the main main valve body 150 constitutes 40 μm ρ 乂, = / IL.

Description of the invention (65) Valve 4 flows in, decompresses to low pressure, and more importantly, enters outside and exchanges heat with outdoor air to evaporate. The room is replaced by ^ 3 low-pressure steam refrigerant, which passes through the four-way compartment door 2 And returning to the dehumidification operation of this heated house again, because the indoor air is at the second = ΪΓΛ B, and it is cooled and dehumidified in the first indoor heat exchanger 5, it can be turned into a fork room and dehumidified. In addition to the number of fan rotations of the outdoor heat exchanger 3 of the rotating outdoor heat exchanger 3 in the heating room, the heating room is controlled by the first indoor heat exchanger 5 and the heating temperature can be wide range. The temperature of the blown out is controlled. Moreover, the opening degree of the worker lice is set to 4 or the number of indoor fan rotations, and the condensation temperature of the first heat to the internal heat exchanger 5 can be controlled by the first room = the amount of air dehumidification. The two-flow control system is set to ON: 5 The second system is controlled to, for example, ^ of the second indoor heat exchanger 7 becomes 10 ° c. 7 The supercooled part of the spider is so, in this embodiment, because it is used as The main body of the valve body is used, and the flow control valve is used for dehumidification during heating.

Degrees, equal ^ while controlled by the second flow control valve. Since the evaporation temperature of the first indoor heat exchanger 5 is approximately equal to the temperature of the intake air in the room, in the first room, the exchanger 5 is hardly cooled and dehumidified. As a result, the heat transfer area of the condenser in the warm room is normally operated in a warm room. For this reason, the condensation temperature system usually rises in greenhouse operation, and the blowout temperature system may become high. What's more important is that during the high-temperature blowing operation of this greenhouse, the refrigerant flow sound in the second flow control valve 6 does not occur, and there is no problem on the noise side. The specific heating room operation control of the adjusting device is described in the first embodiment, and the air temperature and humidity are input. The air-conditioning cracking operation is performed for a predetermined time, for example, 5 minutes of normal heating room operation. Thereafter, corresponding to the switching control in the normal greenhouse operation when the greenhouse operation is started, the second flow control valve 6 is as shown in FIG. 57 (a shows the main valve Π body 150 in the second flow control device and the first indoor pumping device = The compressor i is started by the throttle state in which the end of the continuous pipe 9 and the end of the second indoor heat exchanger are continuously in contact with the end of the official heat exchanger 13. At this time, "the cooling in the first indoor heat exchanger 5 The dehumidification capacity is changed to = the number of fan rotations of the heat exchanger 3 or the opening degree of the first flow control wide door 4 and the like. The evaporation temperature of the first indoor heat exchanger 5 is controlled to be equal to the temperature of the intake air. When starting from the compressor, Γ is passed; when the two-flow port system is turned on as shown in Figure 57 (b), it is transferred to a normal greenhouse operation.

If the temperature deviation or the fan of the fan is in operation due to the normal operation of the greenhouse, the temperature deviation is detected, and the temperature deviation is 0 or less, and the humidity deviation is 0, or In the case of a predetermined value, the normal greenhouse operation is continued. On the other hand, it is necessary to humidify the system at a predetermined value, i 'must be dehumidified, = surface: in the throttling state of the humidity deviation 6 series as shown in Figure 57 (a), I 2nd control valve During this dehumidification operation in a greenhouse, the room is operated in a humid state. ◦ Or the preset value is based on the second indoor heat exchange in two dimensions = the humidity deviation is within 0 or the preset value,…, and is: 5 VP ^ ° ^ ^ ^ τ is based on the rotation frequency of compressor 1 Or room ..., inside control, rotation speed, etc. In addition, the first room: the second morning: the rotation of the indoor fan is controlled according to the opening degree of the control valve 4 of the dehumidification amount of the outdoor heat exchanger. The π number of revolutions or the first flow rate is so. In this embodiment, corresponding to the negative temperature of a warm room, the refrigerant circuit is switched to the optimal output time, operating time, or occupant's preference.

P.76 504559 V. Description of the invention (73) It is important that the porous system is cylindrical and easy to process. More importantly, the refrigerant inlet of the porous body can be enlarged. Sai endurance has also been greatly improved. In this embodiment, a case where the porous system is formed cylindrically is described, but it is sufficient if it has a shape that fits the space of the valve body 15 and the valve seat 154. Fig. 68 of Fig. 7 is a sectional view of the structure of the second flow control device of the air-conditioning apparatus of the present invention, and the same or the same structural elements as those shown in Fig. 55 are denoted by the same symbols, and repeated descriptions thereof are omitted. Fig. 69 is a detailed view of the holes 1 56 used in this flow control device. The main valve body 150 and the valve seat 1 $ 4 are formed of a commonly used resin or metal, and are turned on and off by the electromagnetic core 155, and the main valve body 150 is moved up and down in the valve room. In the valve chamber formed by the main valve body 150 and the valve seat 154, the refrigerant flow path of the valve seat 154 to the bypass valve 13 is bypassed around the cylindrical valve seat 54.

In the refrigerant flow path, the ventilation pore size is made from 1000 micrometers to 500 micrometers, and the porous body 152 is slightly flush with the upper end of the valve seat 54, and the same is more important. Four holes 1 56 having an inner diameter of 0.5 mm and a thickness of 1 mm are arranged equally between the bodies 152 in the refrigerant flow direction. The hole 156 / the upper and lower porous bodies 152 are sandwiched and fit into the side wall of the valve chamber, and the lower side is ′ abutted against the bottom surface of the valve chamber on the downstream side of the refrigerant flow and is fixed at a fixed position. The valve seat 154 is located in the lower part of the valve chamber (piping 9 side) = the refrigerant flow path is connected to the piping 13 and a certain distance is left.

The ventilation holes and holes 1 5 6 of the porous body 52 are pipes 9 connecting the first indoor heat exchanger 5 and the second room

The pipes 13 connected to the internal heat exchanger 7 are connected. N

The pores 156 and the porous body 152 are used together as a function of a throttle. The pores 1 5 6 are in close contact with the porous body 1 5 2 above and below. The porous body 15 2 on the upper side (the upstream side of the refrigerant flow) of the holes 1 5 6 passes the gas-liquid two-phase refrigerant in a mixed state, and prevents the pressure fluctuation generated by the holes 1 56 from being transmitted to the upstream side. The porous body 15 2 on the lower side of the hole 1 5 (the downstream side of the refrigerant flow) has no pressure drop caused by the hole 1 56 but prevents the pressure fluctuation caused by the jet on the outlet side from being transmitted to the downstream side. The refrigerant flow system in the refrigeration cycle is stable, and the air-conditioning system can quickly approach the target air-conditioning environment.

The piping 9 of the refrigerant inlet is connected to the side of the valve chamber, and the refrigerant flows from the side of the valve chamber through the piping 9 to the refrigerant. At this time, the main valve body 150 is positioned up and down in the center of the valve chamber, and the task of diffusing elements for diffusing incoming refrigerant is performed. The refrigerant flowing in from the piping 9 collides and diffuses in the main valve body 150 in this way, and can prevent the refrigerant from colliding with the interior wall of the valve on the opposite side of the piping 9 and inflowing into the porous body 1 5 2 on the opposite side of the piping 9 to effectively use the refrigerant. Flow path. In addition, the valve ’s interior wall collided and diffused, and the valve

V. Description of the invention (75) In the refrigerant collision side of the door chamber and the piping inflow side), the phase of the refrigerant in the gas-liquid two-phase refrigerant section is not uniform. The center of the valve chamber diffuses the inflow refrigerant into the porous body 152. (The diffused refrigerant is separated from the porous body by the liquid and gas in the 152 series, and it flows through the throttling valve. However, the main valve body is in the upper end of the valve seat 154, which is more uniform in the refrigerant phase state.) The upper surface of the body 丨 52 is slightly flush, so when the valve is opened (the main valve body 150 moves upward and leaves the valve seat 1 & 4), the refrigerant flowing from the piping 9 is smoothly on the valve seat 丨Flow inside 54. In addition, the upper end of the valve seat 154 and the upper surface of the porous body 52 are slightly flush with each other, so that the height of the valve chamber can be reduced. The main valve body 5 is located between the valve seat 1 5 4 The corners around the contact surface, when the valve is closed (the state where the main valve body 1 50 and the valve seat 1 5 4 are in contact) is not in contact with the porous body 1 $ 2, the porous body 152 does not necessarily have to be in contact with the main valve Body 丨 50 strength or resistance to abutment. The valve seat 1 5 4 system is integrated with the hole 1 5 6 —the hole 1 5 6 is in close contact with the porous body 1 5 2 system, so the valve seat 1 5 4 _ porous The positional relationship of the bodies 1 5 2 is also maintained to a certain degree, and the main valve body 50 and the porous body 52 do not contact with each other even after years of use. In the structure, since the main throttle portion has holes 156, the porous pore size of the porous body 1 2 of the sintered metal of the auxiliary throttle portion can be increased, and the endurance of the hole clogging is improved. Also, because the valve's seat 154 and The position of the 'valve seat 154 that is integrally formed with the hole 156 is easy to determine. More importantly, because the porous body 15 2 is arranged directly in front of and behind the hole 1 56, the gas-liquid two-phase refrigerant can also pass continuously. In order to reduce the sound of refrigerant flow, four examples of holes 1 5 6 are shown in the example. However, due to the inner diameter and thickness of the holes,

The main valve body 50 has a low contact surface. As a result, in the state where the main valve body 15G is in contact with the porous body i52h, a flow path is formed by the groove 153. Because this flow path is very narrow, the flow Road resistance is large, so it is constituted as the main throttle unit Hole section.

Through the formed hole portion, the pipe connected to the first indoor heat exchanger 5 and the pipe 13 connected to the first indoor heat exchanger 7 are connected. In this structure, since the main throttling part is a hole, the ventilation pore diameter of the porous body 152 of the sintered metal of the auxiliary flow part can be increased, so that the hole endurance is improved.

This body undergoes heat exchange and condenses into a gas-liquid two-phase micro-decompression, and becomes a one-phase refrigerant which is a gas-liquid two-phase refrigerant that migrates slightly in the first flow control device 4 and is heated in the first room.

At this time, through the first, the first to the internal heat exchanger pressure, it becomes a low-pressure gas-liquid phase, phase; inside: the refrigerant in the hole 23 of the device is reduced (point E in the second-chamber In the second room, the sensible heat and latent heat of the flowing air are exchanged to the low-pressure steam refrigerant in the second unit. Once again, the air from the parent unit 7 is cooled and dehumidified in the first indoor unit 7 to prevent the room from dehumidifying. In the first room, heat exchange is performed in the first room. In poetry, the room temperature is lowered and dehumidified.

2148-3761-Pf.ptd Page 100 504559 V. Description of the invention (97) There is almost no pressure loss between the converter 5 and the second indoor heat exchanger 7 continued. At this time, the compressed high-temperature and high-pressure vapor refrigerant operating at the number of revolutions corresponding to the load of the air conditioner passes through the four-way valve 2 and condenses and liquefies at the converter 3, with almost no pressure loss. It is liquefied in the second indoor heat exchanger 7 and decompressed in the second control device 4 to become a low-pressure two-phase refrigerant. 7 =: = 9 gasification is performed outdoors, evaporates and vaporizes, and it is a four-way low-vapor vapor refrigerant. Valve 2 returns to compressor 1. In the case of Danren, the state of the second flow control device will not cause a decrease in the heating capacity or efficiency of the house. The hand f will not be able to know the force. The 4 series control is for example, in the compressor i: 入 = [Again, the first-flow control device. . . . In this way, Lengkang Xun! 部分 part of the superheat of the refrigerant becomes π to take away the heat outdoors, in the room: 孰 m evaporates from the refrigerant and releases from the indoor =, and makes the room: the media condensation and wet the outdoor belt Time of action. Figure 83 = Force— / Line diagram illustrates that A ~ G of the reheat removal circuit of the greenhouse are respectively directed to the library. = 22 ^ ~ 6, which is the same as the refrigerant in Fig. 78. It is discharged from point F in the second room and is discharged from the machine 1. It is reduced by the two-flow control valve 6 of the four-way valve 2 to change: changer 7 Condensation becomes point E 'in the first inflow. At this time, the second chamber is the sixth point, and the first indoor heat exchanger 5 and the first-indoor heat exchanger 5 are used as the parent converter: acting for the reheater ', and acting through the first flow control valve: t. . Thereafter, 'C is cycled through point C. Also, in this example, it is said that "the cold fan is in the state of overcooling at the point E at the time of inhalation F of the shrinking machine 1; The control door 4 is fully opened, and the pressure is shown by the dotted line in FIG. 3. This medium is based on the first indoor heat exchanger 5 and it is impossible to cool below the dew point temperature of the cold air at this time, so ',,,,,' is not used for indoor air compression; the number of rotations is adjusted to control the steam temperature. It is also possible to adjust the wind or the temperature below. As a result, when the indoor rolling dew room is dragged, the cooling and dehumidifying air is mixed with the air heated in the first to the second heat exchange, and the plug of the first heat exchanger 5 is sent in the first. When the degree in Figure 83 decreases, adjust the blowout temperature of the first ΛΛ chamber = = temperature. The action in Fig. 84 is related to the 8th: the second integral flow control valve 4, so a pressure difference door is created between B and C ..., and the second control-therefore, by performing a reheat dehumidification operation in a greenhouse, the room temperature rises and dehumidifies. In other words, ΐί ^ Κ: US Lang, heating season 'will control the room temperature (decrease, equal, rise) corresponding to the necessary air-conditioning load and dehumidify. The flow control valve 6 of this example is a porous permeation material 211 & hole 212 and a porous perforation material 2Ub. The throttle unit is integrally rotated to switch between the flow passing through the throttle unit and the flow through the throttle unit. The flow of the flow section allows the flow of the refrigerant to be controlled even if it is reversed. The cold room reheat dehumidification and the warm room reheat dehumidification are jointly realized by this one flow control device, and a refrigeration cycle with a small number of components can be realized. At this time, when the holes 21 2 pass through the gas-liquid two-phase refrigerant, noise occurs, but

V. Description of the invention (99) ^ Because there are porous permeable materials 211a and 211b before and after the pores, the sound of refrigerant flow can be greatly reduced when the gas = one-phase refrigerant passes. Therefore, in Xi Zhou ° ^: AM ^ countermeasures that need to place sound blocking materials or vibration damping materials in the throttling device are not needed, which reduces costs, and more importantly, the resilience of air conditioning devices is also improved. . The m S srfn porous material 21 is a nickel, nickel-chromium or non-foamed metal having an average diameter of vent holes of ^ and a thickness of about 1 mm to 10 mm. The second flow control device 6 is composed of condensation and falling == plus a pressure difference of 2-8K. The pressure loss corresponds to porous permeation ’and the thickness can increase the noise reduction effect, so that the thickness of the porous permeation material of at least 1 to 3 mm can be miniaturized. In addition, since the plurality of materials are eroded by the jet through the porous material, the 膂: through I is required iVJ: a gap of more than one meter. The hole diameter is made large in the refrigeration cycle when σ is made, and the force is lost. However, less than 0.1 mm is caused by printing accuracy or mass production problems, so it is made about 0.5 to 2 mm in diameter. . The problem of foreign matter in the 21 la ^ Vnt medium circuit is that the diameter of the vent hole of the porous permeation material la and 21 lb is made 100% of the average refrigerant circuit. "&Quot; m ~ 500 " m Stabilization by blocking: Porous permeable materials are set on both sides of the hole. However, this is to rectify the distribution of liquid and gas finely in the cold. The area of the porous permeation material is wide = the direction which is improved by reducing the pressure loss and the sound of the pressing sound, makes the device large

V. Description of the invention (100), so there are flow paths connected, and the flow rate is controlled horizontally, vertically, and obliquely. In addition, strong materials such as vertical and downward directions are integrally formed. However, they are integrated with the frame coating, etc., the degree of freedom of the door driving device, the unsintered net, the number of layers of metal, and the heat exchanger. It is directly sucked to close the first valve body that normally operates the bypass return exchanger to prevent the grinding. The effect of this example is to eliminate or eliminate the porous sintered gold overlapped net. This can also be used to control the opening and closing of the refrigerant system. It is a trail that elevates the temperature of the road and is only equipped with a path that is more than twice the size of €. The setting direction of the control valve is for the refrigerant to flow into the water. Any method can be used. It has the same effect when it is placed obliquely. The refrigerant can flow from the bottom to the top. The frame 210 is made of iron, stainless steel, or copper. The porous permeate material body 2 1 5 is made of brass, non-steel, resin, etc., and the contacts do not leak and rotate due to contact. , Consumption by fluororesin or the occurrence of shavings. Since the flow control valve is integrated with the flow control mechanism and the valve sound mechanism, it can be miniaturized, and it can be easily installed and installed in an indoor unit with an increased number of air conditioners. The permeation material 20 is not only a foamed metal, but a metal powder or ceramic porous permeation material, or a metal-metal mesh, and a number of sintered metal meshes which are sintered and overlapped, can obtain the same effect. In the example, the structure that flows outdoors during the reheating and dehumidifying operation of the greenhouse is explained. However, as shown in FIG. 96, the indoor heat exchange is bypassed to the outdoor heat exchanger, and a bypass circuit to the compressor valve 240 may be added. . During dehumidification, the on-off valve 240 of the bypass circuit of the control device 4 is opened, and the on-off valve 240 of the bypass circuit is closed and installed. Since the addition of 'is not about the temperature of the outside air, the control system of the indoor temperature is possible, and the dehumidification capacity can be more stable.

504559 V. Description of the invention (101) Local control. For this reason, the stability of the refrigerating cycle can be obtained without lowering the discharge temperature of the compressor. Fig. 85 is a cross-sectional view of another structure of the flow control device 6. The 9-series first flow path connection pipe, the 13-series second flow path connection pipe, the 2 丨 0 valve frame, and holes between the porous permeable materials 211. 212. A gap 214 is formed between the porous permeable material 211 and the hole 212. The gap 21 4 series is set between 0 and 3 mm. The thickness of the porous permeable material is set to 1 mm to 5 mm, and the valve body 2 15 fixed in the frame body 21 is rotated through an area of 70 mm 2 to 70 mm 2. The holes 2 丨 2 also rotate integrally with the rotating valve body 2 丨 5. In addition, the first flow path connecting pipe 9 and the second flow path connecting pipe 13 are installed at positions 远离 away from the rotation center of the valve body 215. The driving device of the valve body is the same as the flow control device described above. Fig. 86 is a cross-sectional view of the valve body as seen from the same structure of Fig. 85 on the side of the first flow path connecting pipe 9. In Fig. 85, the base of the valve body 215 of the flow control device is rotated in the valve frame 210. When operating in a cold room as in Fig. 85 (&), the refrigerant is the first flow path connecting pipe 9, and the porous material passes through. Materials 2 n, pores 2 and 2, porous permeable material 211, and second flow path connecting pipe 13 flow in sequence, and the refrigerant is decompressed between the first inner heat exchanger 5 and the second indoor heat exchanger 7. As shown in Fig. 85 (13), the refrigerant is the first connection pipe of the first-stage circuit 9. It is in the front of the door frame 0 without passing through the porous material 2 丨 i. The second flow path connecting pipe 3 flows, and there is almost no pressure loss between the first inner heat exchanger 5 and the second indoor heat exchanger 7. When rotating the valve body 21, 5 DC motor, stepping motor system

504559 V. Description of the invention (102) 'Driven by a reduction gear. In addition, the refrigerant flow is reversed when the greenhouse is operated and the greenhouse is reheated and dehumidified. Fig. 86 (a) shows a porous permeation material having a refrigerant flow path in the center of the figure, as seen from the first flow path connecting pipe 9 in Fig. 85 (a). On the other hand, Fig. 86 (b) is seen from the first flow path connecting pipe 9 in Fig. 85 (b). In this figure, the effect of this structure is the same as that already described. However, the second flow control device When the rotating space in the valve body 2 1 5 is used and opened in the frame 2 10, that is, the device can be miniaturized without using holes and circuits. Fig. 87 and Fig. 88 are external views and cross-sectional explanatory views of a throttling device of another structure. In the figure, the 2008 series rotation drive device, the 9 series first flow path connection piping, the 13 series second flow path connection piping, the 2 10 series frame, the 2 1 6 series silencer, and the first flow path connection piping 9 The second flow path connecting pipes 1 and 3 are connected at the muffler respectively. Fig. 88 is a detailed cross-sectional view of Fig. 87. 211 is a porous permeable material. There are holes 2 1 2 'between the two porous permeable materials 211. The porous permeable material 2 11 and the pores 2 1 2 are generated. Gap 2 1 4 The gap 2 1 4 is set between 0 and 3 mm. The porous permeable material is not thicker than 1 mm to 5 mm ′ and is fixed to a rotatable valve body 2 1 5 with a passing area of 70 mm 2 to 700 mm 2. The hole is also integrated with the rotatable valve body 2 1 5 and is fastened to other components. The valve frame 2 10 includes an opening portion 21 7. The door frame 210 is a structure in which a muffler 216 is attached and fixed. < In Fig. 88, the valve body 215 of the flow control device is rotated in the valve frame 2 10, and as in Fig. 88 (a), the first flow path connecting pipe 9, the muffler 216, the opening 217, and the perforation Mass-permeable material 211, holes 212, porous ^

504559 V. Description of the invention (103) The permeating material 2 1 1, opening 2 1 7, muffler 2 丨 6, second flow path connecting pipe 1 3 flow in sequence, and the first indoor heat exchanger 5 and The refrigerant between the second indoor heat exchangers 7 is decompressed. The gate body 215 of the base of the rotating throttle device is set as shown in FIG. 88 (b). The refrigerant is the first flow path connecting pipe 9, the muffler 2 1 6, the opening 2 1 7, and the porous permeating material 2 丨 i. The space in the front, the holes 212, the porous permeable material 211, the opening 217, the silencer = 2 1 6 and the flow of the second flow path connecting pipe 1 3, and the first indoor heat exchanger 5 and the first indoor heat exchanger There is almost no pressure loss between the devices 7. When the valve body is rotated 2 1 5 ', the DC motor and stepping motor are driven by a reduction gear. In addition, when the greenhouse is operated, the refrigerant flow is reversed when the greenhouse is reheated and dehumidified. The effect of this structure is the same as that described above. However, the use of a muffler can achieve a lower voice. In other words, since the muffler is included, the effect of reducing the sound of the refrigerant through the rectifying effect of the porous material 21 is increased, and the effect of reducing the sound of the refrigerant by the muffler can be obtained. In addition, as shown in Fig. 88 (b), the muffler 2 16 is used, and the opening portion of the valve frame 2 10 in the throttle portion can be widely used. There is almost no pressure drop caused by the throttle portion. Fig. 89 and Fig. 90 are an external view and a sectional explanatory view of a throttling device of another structure. In the figure, the 2008 series is a rotary drive device, the 9 series is the first flow path connecting piping, the 31 series is the second flow path connecting ‘pipe, the 2 10 series valve frame, and the 2 1 6 series silencer. Fig. 90 is a detailed cross-sectional view of Fig. 8-9. 2 11 is a porous permeable material, and a porous permeable material 2 1 1 a and 2 11 b on one side has an interval 21 8 between the two. There are two spaces on the side. Connected to this space, respectively, with holes 2 1 2a and holes 2 1 2b, followed by a porous pervious material on the opposite side

2148-3761-Pf.ptd Page 107 504559 V. Description of the invention (104) Material 211c. A gap 214 is formed between each of the porous permeable materials 211a, 211b, and 211c and the holes 212a, 212b. The gap 214 is set between 0 and 3 mm. The porous permeable material is set to a thickness of 1 mm to 5 mm, and is fixed to a rotatable valve body 215 through an area of 70 mm2 to 700 mm2. The holes 212a and 212b are also integrated with the rotatable valve body 215 or fixed to other components. The valve frame 210 includes an opening portion 217. The frame body 210 is a structure in which the muffler 216 is attached and fixed.

In Fig. 90, the valve body 2 and 5 of the flow control device rotate as in Fig. 90 (a), and the refrigerant is the first flow path connecting pipe 9, muffler 2 1 6, opening 217, and both sides. There is no space behind the porous permeable material 211, the opening 21, 7, the muffler 2 1 6, and the flow path of the second flow path connecting pipe 3 丨 flow in sequence, and the heat is generated in the first indoor heat exchanger 5 and the second room. There is almost no pressure loss between the exchangers 7. In addition, the valve body 2 1 5 of the rotary flow control device is set as shown in FIG. 90 (b), and the refrigerant-based first flow path connecting pipe 9, the muffler 2 1 6, the opening 2 17, and the opening 2 17 Two spaces separated by an interval of 21 and 8 are respectively provided. The porous permeable materials 211a and 211b, the holes 212a and 212b, the porous permeable material 2Uc, the opening 217, the muffler 216, and the second flow path connecting pipe 31 are separately provided. The flow is sequentially performed, and the refrigerant is decompressed between the first indoor heat exchanger 5 and the second indoor heat exchanger 7 by flowing through the throttle section. More importantly, when the door reader 215 is rotated as shown in FIG. 90 (c), the refrigerant system is separated by the space 218 and flows in a space separated by space 218. For this reason, since the refrigerant system flows through only one hole 21 2 a, the amount of decompression is larger than that shown in FIG. 90 (b). In addition, as shown in Fig. 90 (d), the valve body with the seat is rotated, and the refrigerant is spaced by the space between the other 2 2 8

504559 V. Description of invention (105). For this reason, the refrigerant system only flows in 2m of one hole. Here, by changing the inner diameters of the holes 2 12a and the holes 21 2b, it is possible to adjust the decompression amount different from that shown in FIG. 90 (c). At this time, when the valve body 2 and 5 are rotated, the DC motor and the stepping motor are driven by a reduction gear. In addition, when the greenhouse is operated, the refrigerant flow is reversed when the greenhouse is reheated and dehumidified. ......... The effect of the example of this structure is the same as above, but according to the pressure-enthalpy curve of Fig. 82, it is at the inlet (D) of the refrigerant system gas-liquid during the dehumidification operation of the cold room. The two-phase state, however, according to the first graph ^ pressure-enthalpy curve, the state of the refrigerant at the inlet (E) of the flow control device 6 during the dehumidification operation of the greenhouse is a liquid state. When a hole with the same cross-sectional area passes through the refrigerant, the liquid phase has a larger pressure loss than the gas-liquid two-phase state. For the flow of a predetermined amount of refrigerant, the throttling during the dehumidification operation of the warm room must be larger than that during the dehumidification operation of the cold room. The flow control valve 6 of this structure is corresponding to the rotation angle of the frame 210 by the valve body 215, and the pressure of the refrigerant can be set in two to three stages. Therefore, during cold room dehumidification operation and warm room dehumidification operation, the flow rate can be changed to control the optimum dehumidification operation. For example, in the case of a hole-facing surface (hole 212a + hole 212b) > (hole 212a) > (hole 2i2b), when the normal cold room operation and warm room operation are performed, the state of the flow control figure 90 (a) is almost No pressure loss. The cold reheating and dehumidifying operation 'is in the state shown in Fig. 90 (b). At this time, the evaporation temperature of the second-inner heat parent converter 7 is optimal during the reheating and dehumidifying operation of the cold room, and the throttle of the cold room is set to the cross-sectional area of the holes 21 2 a + 21 2 b. In addition, when the greenhouse is reheated and dehumidified, it is in the state of Fig. 90 (1)). At this time, the evaporation temperature of the refrigerant in the first indoor heat exchanger 5 is reheated in the greenhouse.

504559 V. Description of the invention (106) The dehumidification operation is optimal. The cooling capacity of the cold room is set to the cross-sectional area of the holes 2 1 2b. "The state of Fig. (C) or (d) when the evaporation temperature of the second heat exchanger 7 decreases, such as when the amount of dehumidification is increased during the cold room reheating and dehumidifying operation," is compared with the refrigerant section in Fig. (B). Increased traffic. In addition, when the evaporating temperature of the first heat exchanger 5 is increased when the dehumidification amount is reduced during the reheating and dehumidifying operation of the greenhouse, the state of FIG. (B) or (c) is lower than the state of FIG. (D). The reduction of throttling. 'This way' During dehumidification in cold room, dehumidification is possible during dehumidification in warm room. If the indoor temperature is below the open-air temperature and the drain pipe water is not frozen above 2 ° C, the evaporation temperature of the indoor evaporator is set. In this range, when the amount of dehumidification can be increased, the evaporation temperature decreases. When reducing the amount of dehumidification, the evaporation temperature ^

The temperature can be controlled optimally by keeping the evaporating temperature of the indoor evaporator ascending. ', L More importantly, since the structure example includes a muffler, the effect of reducing the refrigerant sound by the rectifying effect of the porous permeable material 211 is increased', and the effect of reducing the refrigerant sound of the muffler can be obtained. In the example of FIG. 90, an example of a gap θ corresponding to one of the openings of the housing 21 is described. However, the number is variable, and the interval is shaped from a shape that is not linear in the direction of the rotation axis. It is also possible to reduce the amount of flow by several times, and fine dehumidification control can be performed. ‘Dingmu head Figures 91 and 92 are explanatory diagrams of the outer section of a throttling device of another structure. In the figure, 208 is a rotary drive device, 9 is the second-== continued pipe, 31 is the second flow path connecting pipe, and 21 is the valve body. Detailed diagram of the connection 90 is shown in Figure 89, and 211 is porous Mass permeable material, 2

504559 V. Description of the invention (107) It is a disc-shaped plate that rotates on the surface including a plurality of holes, 222 is an interstitial plate with an inner diameter greater than that of a continuous pipe, and 221 is a component that fixes a porous permeable material 211 The hollow plate 222 and the element 221 are integrated. 219 is a shaft of a rotating disc-shaped plate, which is connected to the driving device 208. The disc-shaped plate 220 and the interstitial plate 222 are sandwiched between the porous permeable material 211 and the disc-shaped plate 2 2 0 and the interstitial plate 2 2 2 have a certain gap between the porous permeable materials 2 1 0 2 1 4. The gap 2 1 4 is set between 0 and 3 mm. The porous permeable material 211 is thicker and thicker, and passes through an area of 70-2 to 700 mm2. 2 2 3 is a series of communication holes. Fig. 93 is an explanatory diagram of holes that are seen when the disc-shaped plate 220 provided with a plurality of holes rotates and the cavity plate 2 2 2 fixed in the valve frame 210 is taken out and overlapped, 212c, 21 2d, 21 2e, 21 2f series of holes, 223 series of interstitial plate 222 opened. In Fig. 93 (a), the refrigerant-based first flow path is connected to the piping, the porous permeable material 211, the holes 212c, and the porous permeable material 211 is passed through the second flow path to connect the piping. The disc-shaped plate 220 is set as shown in Figure 93 (b), Figure 93 (c), and Figure 93 (d) of the rotation. In the case of Figure 93 (b), the hole 212f and Figure 93 (c) are used. In the case of the hole 212e and Fig. 93 (d), the refrigerant flows in the hole 21 2 d. At this time, the inner diameters of the holes are changed, and the amount of decompression of the refrigerant can be changed by the number of holes. The pressure loss of the refrigerant between the first indoor heat exchanger 5 and the second indoor heat exchanger 7 can be adjusted. In addition, the inner diameter of the hole is greater than the inner diameter of the communication hole 223 of the interstitial plate 222, and the first flow path connecting pipe 9 and the second flow path connecting pipe 3 1 are larger than the inner diameter and the refrigerant flowing through the throttling device is not reduced. This causes the refrigerant to flow. At this time, between the first indoor heat exchanger 5 and the second indoor heat exchanger 7 becomes

In addition, the operation of the heating house, the heating of the house again, and the removal of the heart, and the refrigerant flow during the operation are reversed. In this structure, the reduction of the refrigerant in the hole has the same effect as the above. Figure 93 shows the effect. Also, ㈣m, 2 The same effect can also be obtained ^ The example of the structure in Figure 3 is a structure that rotates the rotating disk of σ gf & $ and can not only be small: force,: two configurations.
