Description

The present invention allows water vapor to flow through the duct in a reversible direction by reversibly moving a Roots pump arranged via a duct between the evaporator and the condenser without providing a separate switching valve. The present invention relates to an air conditioning system using a steam compression refrigerator that supplies cold water or hot water to a load constructed by a radiant panel or the like provided in a living room or the like.

This type of first example of the prior art is an air conditioning system having the configuration shown in FIG. In this regard, 1 is an evaporator, 2 is a condenser, and 3 is a compressor. The evaporator 1, the condenser 2 and the compressor 3 constitute a compression refrigerator A. The evaporator 1 cools a part of cold water introduced from the load 10 while maintaining a low pressure by the operation of the compressor 3. The compressor 3 pressurizes the refrigerant gas introduced from the evaporator 1 under predetermined conditions. The condenser 2 introduces the refrigerant gas that has been pressurized by the compressor 3 and has reached a high temperature, cools it with cooling water from the outside, condenses, or warms the hot water to the load 10. Reference numeral 4 denotes a primary side cold / hot water pipe which is connected to a heat source water 5 such as well water and is provided with a first switching valve 6, a cold / hot water pump 7, a condenser 2 and a second switching valve 8 interposed therebetween. . Reference numeral 9 denotes a secondary side cold / hot water pipe which is connected to a load 10 made of a radiant panel or the like and is arranged with a third switching valve 11, a cold / hot water pump 12, an evaporator 1 and a fourth switching valve 13 interposed therebetween. It is. Reference numeral 14 denotes a fifth switching valve, which is interposed in a first branch pipe 15 connected between the secondary side cold / hot water pipe 9 and the primary side cold / hot water pipe 4. Reference numeral 16 denotes a sixth switching valve, which is interposed in a second branch pipe 17 connected between the secondary side cold / hot water pipe 9 and the primary side cold / hot water pipe 4. Reference numeral 18 denotes a seventh switching valve, which is interposed in a third branch pipe 19 connected between the secondary side cold / hot water pipe 9 and the primary side cold / hot water pipe 4. Reference numeral 20 denotes an eighth switching valve, which is interposed in a fourth branch pipe 21 connected between the secondary side cold / hot water pipe 9 and the primary side cold / hot water pipe 4.
Thus, during the cooling operation, when the compression refrigerator A is operated, the cold / hot water pump 7 is driven and the first and second switching valves 6 and 8 are opened, and the heat source water 5 is disposed on both sides. For example, the heat source water 5 on the inlet side flows through the primary cold / hot water pipe 4 that has been piped through the condenser 2 as having a temperature of about 37 (° C.) to 27 (° C.). The temperature is about 32 (° C.) to 22 (° C.).
On the other hand, the evaporator and the cold / hot water pump 12 are driven and the third and fourth switching valves 11 and 13 are opened, and the secondary cold / hot water pipe 9 piped on both sides of the load 10 is provided. For example, cold water of 7 (° C.) flows through the evaporator 1, a heat medium made of cold water is sent to the load 10 such as the radiant panel, and the room where the load 10 is installed is cooled. This is the cooling operation of the air conditioning system, that is, the summer operation.
In the heating operation, the compressor / refrigerator A is operated to drive the cold / hot water pump 12 and the sixth and eighth switching valves 16 and 20 are opened and piped on both sides of the heat source water 5. For example, the heat source water 5 on the inlet side flows as 7 (° C.) cold water through the evaporator 1 in the primary side cold / hot water pipe 4, the second branch pipe 17, and the fourth branch pipe 21. And has a temperature of about 12 (° C.) on the outlet side.
On the other hand, the condenser 2 and the cold / hot water pump 7 are driven, and the fifth and seventh switching valves 14 and 18 are opened, and the secondary cold / hot water pipe 9 is piped on both sides of the load 10. Then, for example, 45 (° C.) hot water flows through the first branch pipe 15 and the third branch pipe 19 via the condenser 2, and the hot water is sent to the load 10 such as the radiation panel. Heat the living room where is installed. This is the heating operation of the air conditioning system, that is, the winter operation.

As a second example of this type of prior art, there is an apparatus shown in FIG. 7 disclosed in Japanese Patent Application Laid-Open No. 60-62539. To explain this, a vacuum vessel 22 having a bottom outlet 21 is included, and water in the vacuum vessel 22 can be pumped from the bottom outlet 21 by a pump 23 and passed through an external heat exchanger 24. Is returned to the vacuum vessel 22 through the nozzle tube 25, that is, water from the nozzle tube 25 is sprayed into the vacuum of the vacuum vessel 22 onto the water surface in the vacuum vessel 22 through the nozzle 25a. This injection spray causes significant evaporation and associated cooling of the water, which partially freezes before hitting the water 26 in the vacuum vessel 22. The vapor produced by this injection spray is removed to maintain the low pressure in this vacuum vessel 22. This removal method is performed by a simple centrifugal compressor 27, which sucks this vapor into the upper chamber 29 through the drop separator 28, and constitutes the evaporator unit of the conventional refrigeration apparatus B in the upper chamber 29. The refrigeration condenser 30 is provided, and the condenser of the refrigeration apparatus B is indicated by 31. The pressure in the upper chamber 29 is only slightly higher than in the vacuum vessel 22, which is sufficient for this low temperature vapor condensation to occur without icing the condenser 30. The condensate is collected on the inclined tray 32 and guided back through the tube 33 and directly into the vacuum vessel 22. During “night operation”, this device is used to gradually freeze water 26, which is recirculated through an external heat exchanger 24, and without this unit, this device performs another operation. The conditions are adjusted so that the water 26 is converted to crushed ice as soon as possible, that is, there is no initial total freezing of the water 26, just prior to the next "daytime" period. In other words, the crushed ice floating in the water 26 is optimally made to a degree at the bottom outlet 21 or the pump 23. During “daytime operation”, the heat exchanger 24 is activated. This heat exchanger 24 is additionally included in a circuit comprising one or more devices to be cooled with a capacity greater than that of the pump 23 and the refrigeration system B. Although the refrigeration apparatus B may continue the operation for cooling a large amount of water 26, during the daytime operation, the water 26 is heated through the heat exchanger 24 to a considerable extent for cooling in the vacuum vessel 22. That is, the ice content of the water 26 is continuously reduced, and the heat of fusion is used for cooling the external circuit of the heat exchanger 24. Thereafter, the external circuit pump 34 is turned off and the next night phase begins, at which time the refrigeration system B operates exclusively to fill this large amount of water 26 with fresh crushed ice. During daytime operation, the operating condition of the vacuum cooling device is such that the temperature of the water sprayed through the nozzle 25a is higher than during nighttime operation.
In the figure, 35 is a cooling load, 36 is a motor for driving the centrifugal compressor 27, and 37 to 40 are valves.
Japanese Patent Laid-Open No. 60-62539

Generally, a conventional refrigerator is a refrigerator using a cooling principle of refrigerant evaporation, and uses, for example, a fluorocarbon refrigerant such as HFC-134a or HCFC-123 and has a high global warming potential (GWP). There was a risk of ozone layer destruction and global warming.
Further, the conventional refrigerator needs to produce, for example, 7 (° C.) cold water in the air conditioning system for dehumidification by the air conditioner and supply it to the load, and the difference between the evaporation temperature and the condensation temperature is, for example, 20 (° C) or more is required, and heat source water of 16 (° C) or less in well water cannot be used as heat source water as it is. For example, cooling water of 27 (° C) should be mixed to make 22 (° C) or more. Therefore, the condensation temperature cannot be made 22 (° C.) or less, and there is a bottleneck that the cooling water having a low temperature cannot be effectively used.

By the way, the air conditioning system shown in the first example in the above-described prior art is a cooling / heating system and uses a chlorofluorocarbon refrigerant. However, a medium for cooling / heating water that controls both cooling and heating. In order to switch and supply the load 10 to the load 10, a complicated and large number of first to eighth switching valves 6, 8, 11, 13, 14, 16, 18, and 20 are provided in the system, and in addition, a piping configuration There was a problem that became complicated.

When the water extracted from the bottom outlet 21 of the vacuum vessel 22 is sprayed from the nozzle 25a by the pump 23, a part of the water 26 is actively evaporated, and the remaining water becomes fine ice due to the latent heat of evaporation. A single-stage centrifugal vapor compressor 27 is provided in the upper part of the vacuum vessel 22 and sucks water vapor into the upper chamber 29. The upper chamber 29 is provided with a refrigeration condenser 30 using a compression type refrigeration cycle using chlorofluorocarbon or the like that constitutes an evaporator unit of a conventional refrigeration apparatus B. Since this refrigerator compresses water vapor with the one-stage centrifugal vapor compressor 27, the compression force is a pressure slightly higher than the pressure in the vacuum vessel 22, for example, 7 mmHg, and the temperature of the refrigerant is reduced in order to condense this water vapor. It is necessary to lower it using chlorofluorocarbon. In addition, this refrigerator is a technology that can only produce cooling water for cooling and cannot cope with heating loads.

And the water of the said one side vacuum container 40 is cooled, and cold water is manufactured. As described above, the evaporated water vapor is sent to the other-side vacuum vessel 41 by the compressor 43, that is, the Roots pump, and the other-side vacuum vessel 41 is heated.

On the other hand, the heat source water 46 such as well water is pumped up by driving the pump 46a, and the heat source water 46 flows in the primary connection pipe 48 in the direction indicated by the arrow P2, and the primary side 47a of the heat exchanger 47 And the three-way valve 52 is driven to reduce and flow again to the ground of the ground D. In addition, the three-way valve 52 opens the valve, and a part of the heat source water 46 is also sent to the branch connecting pipe 51 in the direction indicated by the arrow P3. Then, for example, 16 (° C.) heat source water 46 is pumped into the primary connection pipe 48 and the branch connection pipe 51 in the input portion connected from the pump 46 a to the primary side 47 a of the heat exchanger 47. Further, for example, 21 (° C.) heat source water 46 flows from the primary side 47 a of the heat exchanger 47 to the three-way valve 52, and for example, 16 (° C.) heat source water 46 flows in the branch connection pipe 51. And returned to the basement.
In addition, it can replace with the said three-way valve 52, and can be set as the same structure and operation | movement by arrange | positioning two two-way valves. That is, a two-way valve is provided in each of the primary connection pipe 48 and the branch connection pipe 51 at the outlet portion of the primary side 47a of the heat exchanger 47. The outlet temperature of the cooling water flowing through the secondary connection pipe 49 on the outlet side of the other side vacuum vessel 41 is set to a predetermined value by the first thermometer 53 (T1) connected to the secondary connection pipe 49. For example, the flow rate from the heat source water 46 such as well water flowing through the primary connection pipe 48 and the branch connection pipe 51 is controlled so as to be 22 (° C.). The control line 54 is connected between the first thermometer 53 (T1) and each two-way valve, and each two-way valve is measured by the control line 54 with the measured temperature of the first thermometer 53 (T1). The signal is taken in and the opening degree of each two-way valve is controlled.

The heat exchanger 47 is connected to the other side vacuum vessel 41, that is, the condenser, in the secondary connection pipe 49 which is a cooling water pipe as a primary loop of the steam compression refrigerator C connected to the secondary side 47b. The cooling water is flowed in the direction of the arrow P4 so that the cooling water is injected into the container by the injection nozzle 41a or the like, and the temperature of the cooling water is, for example, 17 (° C.). At this time, the other-side vacuum vessel 41 has, for example, a cold water temperature of 22 (° C.) and a saturated vapor pressure of about 2.65 (KPa). It is sent in the direction of P5. At this time, the temperature of the cooling water fed from the outlet side of the other vacuum vessel 41 is measured by the first thermometer 53 (T1), and this measured temperature signal is transmitted to the three-way valve 52 by the control line 54. The three-way valve 52 controls the opening degree of the valve so that the outlet temperature of the cooling water always becomes a predetermined value of, for example, 22 (° C.).

Thus, if the temperature of the cooling water jetted from the jet nozzle 41a is 17 (° C.) and its outlet temperature is higher than 22 (° C.), the temperature difference becomes larger than 5 (° C.), and the circulation pump 50 As a result, the amount of cooling water flowing in can be reduced, the power of the circulation pump 50 can be reduced, and energy consumption measures can be taken.

Thus, the refrigeration operation can be performed by cooling the other-side vacuum vessel 41 with the heat source water 46 such as well water. Then, chilled water is circulated and circulated into the one side vacuum vessel 40, that is, the load side connecting pipe 57 which is a chilled water pipe as a secondary loop of the steam compression refrigerator C connected to the evaporator, Cool down. Then, the interior of the living room 55 is cooled by the summer operation of the steam compression refrigerator C, that is, the cooling operation.
At this time, one side vacuum vessel 40, that is, the outlet side of the evaporator has a chilled water temperature of, for example, 15 (° C.), and the chilled water is in the direction of the arrow P6 by the pump 58, To the side. Further, for example, 18 (° C.) cold water is discharged from the cooling / heating load 56, that is, the output side of the radiant panel or the like, and 18 (° C.) cold water is injected from the injection nozzle 40 a disposed in the one-side vacuum vessel 40. The one-side vacuum container 40, that is, the inside of the evaporator has a saturated vapor pressure of 1.71 (KPa), for example, and 15 (° C.) cold water can be taken out by the pump 58. The temperature signal measured by the second thermometer 59 (T2) is transmitted to the compressor 43, that is, the Roots pump through the control line 60, and the operation of the compressor 43 is controlled. Then, the operation of the compressor 43 is controlled in accordance with the load amount of the cooling / heating load 56 so as to ensure the measured temperature value of the second thermometer 59 (T2) at a constant temperature.
Thus, the basic system for cooling and heating by the steam compression refrigerator according to the present invention controls the flow direction of steam to the compressor 43, that is, the roots pump, without arranging a number of unique switching valves in summer. As a result, the operating efficiency (COP) of the steam compression refrigerator C can be increased and a suitable refrigerant can be flowed to the cooling / heating load 56 to perform the cooling function of the living room 55.

Next, based on FIG. 2, the winter, that is, the heating operation in the basic system for cooling and heating by the steam compression refrigerator according to the present invention will be described.
In the steam compression refrigerator C, the one-side vacuum vessel 40 operates as a condenser and the other-side vacuum vessel 41 operates as an evaporator during a winter operation, that is, a heating operation.
Thus, the water vapor flows from the other side vacuum vessel 41 through the connection pipe (duct) and flows through a roots pump as the compressor 43 that is started up, and flows in the direction indicated by the arrow P7 (from below to above). It flows into the condenser as 40. And the water of the said one side vacuum container 40 is heated, and warm water is manufactured.

On the other hand, by driving the pump 46a, the heat source water 46 such as well water is pumped, and the heat source water 46 flows in the primary connection pipe 48 in the direction indicated by the arrow P8, and the primary side 47a of the heat exchanger 47 And the three-way valve 52 is driven to reduce and flow again to the ground of the ground D. The three-way valve 52 opens the valve, and a part of the heat source water 46 is also sent to the branch connecting pipe 51 in the direction indicated by the arrow P9. Then, for example, 16 (° C.) heat source water 46 is pumped into the primary connection pipe 48 and the branch connection pipe 51 in the input portion connected from the pump 46 a to the primary side 47 a of the heat exchanger 47. Further, for example, 13 (° C.) heat source water 46 flows from the primary side 47 a of the heat exchanger 47 to the three-way valve 52, and for example, 16 (° C.) heat source water 46 flows in the branch connection pipe 51. Sent to the basement.
In addition, it can replace with the said three-way valve 52, and can be set as the same structure and operation | movement by arrange | positioning two two-way valves. That is, a two-way valve is provided in each of the primary connection pipe 48 and the branch connection pipe 51 at the outlet portion of the primary side 47a of the heat exchanger 47. The outlet temperature of the cooling water flowing through the secondary connection pipe 49 on the outlet side of the other side vacuum vessel 41 is set to a predetermined value by the first thermometer 53 (T1) connected to the secondary connection pipe 49. For example, the flow rate from the heat source water 46 such as well water flowing through the primary connection pipe 48 and the branch connection pipe 51 is controlled so as to be 22 (° C.). The control line 54 is connected between the first thermometer 53 (T1) and each two-way valve, and each two-way valve is measured by the control line 54 with the measured temperature of the first thermometer 53 (T1). The signal is taken in and the opening degree of each two-way valve is controlled.

The heat exchanger 47 is connected to the other side vacuum container 41, that is, the evaporator, in the secondary connection pipe 49, which is a cooling water pipe as a primary loop of the steam compression refrigerator C connected to the secondary side 47b. The cooling water is flowed in the direction of the arrow P10 so that the cooling water is injected into the container by the injection nozzle 41a on the input side, and the temperature of the cooling water is, for example, 15 (° C.). At this time, for example, the other side vacuum vessel 41 has a cooling water temperature of 12 (° C.) and a saturated vapor pressure of about 1.40 (KPa). Flowed in the direction of arrow P11. At this time, the temperature of the cooling water fed from the outlet side of the other vacuum vessel 41 is measured by the first thermometer 53 (T1), and this measured temperature signal is transmitted to the three-way valve 52 by the control line 54. The three-way valve 52 controls the opening degree of the valve so that the outlet temperature of the cooling water always becomes a predetermined value of, for example, 12 (° C.).

Thus, the heat pump operation is enabled by supplying the heat source water 46 such as well water to the other side vacuum vessel 41. Then, hot water is circulated through the load side connection pipe 57 which is a hot water pipe as a secondary loop of the steam compression refrigerator C connected to the one side vacuum vessel 40, that is, the steam compression refrigerator C. Heat up. And the inside of the living room 55 is heated by the winter driving | operation of the water vapor | steam compression refrigerator C, ie, heating operation.
At this time, the one side vacuum vessel 40, that is, the outlet side of the condenser, has a hot water temperature of, for example, 30 (° C.), and is directed in the direction of the arrow P12 by the pump 58 to the input side of the cooling / heating load 56, that is, the radiation panel. To be sent. Further, for example, 27 (° C.) hot water is discharged from the output side of the cooling / heating load 56, that is, the radiant panel, and 27 (° C.) hot water is injected from the injection nozzle 40 a disposed in the one-side vacuum vessel 40. The one side vacuum container 40, that is, the inside of the condenser has a saturated vapor pressure of, for example, 4.25 (KPa), and 30 (° C.) hot water can be taken out by the pump 58. The temperature signal measured by the second thermometer 59 (T2) is transmitted to the compressor 43, that is, the Roots pump through the control line 60, and the operation of the compressor 43 is controlled. Then, the operation of the compressor 43 is controlled in accordance with the load amount of the cooling / heating load 56 so as to ensure the measured temperature value of the second thermometer 59 (T2) at a constant temperature.
Thus, the basic system of cooling and heating by the steam compression refrigerator according to the present invention controls the flow direction of steam to the compressor 43, that is, the roots pump, without arranging a number of unique switching valves in winter. As a result, the operating efficiency (COP) of the steam compression refrigerator C can be increased, a hot water medium suitable for the cooling / heating load 56 can be flowed, and the heating function of the living room 55 can be achieved.

Next, Example 1 in the air conditioning system by the water vapor compression refrigerator which concerns on this invention is demonstrated based on FIG.

47 is a heat exchanger, and its primary side 47 a is connected to a primary connection pipe 48 connected to the heat source water 46. The secondary side 47b of the heat exchanger 47 is connected between the first connecting pipe 49a connected between one side and the three-way valve 52a, and the nozzle pipe of the injection nozzle 41a of the three-way valve 52a and the other side vacuum vessel 41.

The first to fifth connection pipes 49a to 49e constitute a primary loop of the steam compression refrigerator C, and generally constitute the other secondary connection pipe of the heat exchanger 47. The secondary connection pipe is composed of a plurality of connection pipes and is connected to the other-side vacuum vessel 41.

A branch connection pipe 51 as a primary connection pipe is connected to the primary side 47a of the heat exchanger 47, and a three-way valve 52 different from the three-way valve 52a is connected. In the three-way valve 52, a temperature signal measured by a third thermometer 53a (T3) disposed in the first connection pipe 49a is transmitted to the three-way valve 52 through a control line 54a, and the three-way valve 52 For example, the heat source water 46, that is, the total amount of well water flows to the three-way valve 52 to the heat exchanger 47 so that the temperature of the cooling water that flows is close to the temperature of the heat source water 46 that flows to the primary connection pipe 48. The feed is controlled to about 17 (° C.).
Note that the three-way valve 52 can have the same configuration and operation by disposing the two two-way valves described in the operation of the basic system shown in FIGS. 1 and 2 instead.
Thus, for example, the circulating cooling water of 22 (° C.) fed from the outlet side of the other vacuum vessel 41 is cooled as much as possible by the heat source water 46 such as well water. Further, a first thermometer 53 (T1) is disposed in the third connection pipe 49c, that is, the secondary connection pipe, and a temperature signal measured by the first thermometer 53 (T1) is transmitted via the control line 54b. Then, the opening of the valve is operated so that the temperature of the cooling water on the outlet side of the other-side vacuum vessel 41 is set to, for example, 22 (° C.) by the operation of the three-way valve 52a.

On the other hand, a sixth connecting pipe 49f connected between one of the secondary sides 47b and the three-way valve 52b in the heat exchanger 47, and between the three-way valve 52b and the nozzle pipe of the injection nozzle 40a of the one-side vacuum vessel 40. A seventh connecting pipe 49g connected to the outlet, the eighth connecting pipe 49h connected via a hot water pump 58a between the outlet side of the one-side vacuum vessel 40 and the branch point A2, and the branch point A2 and the air conditioner A ninth connecting pipe 49i is connected between the other ends of the load 56 with a valve 61c interposed therebetween, a branch point A3 where one end is connected to the fifth connecting pipe 49e, and a valve 61d is connected between the other end and the branch point A2. A tenth connecting pipe 49j connected through the interposition and an eleventh connecting pipe 49k connected between one end of the cooling / heating load 56 and the three-way valve 52b are provided.
The sixth to eleventh connecting pipes 49f to 49k constitute a secondary loop of the steam compression refrigerator C, and generally constitute one secondary side connecting pipe of the heat exchanger 47. is there. The one secondary connection pipe is a load side connection pipe and is configured to be connected to the one side vacuum vessel 40.

A second thermometer 59 (T2) is installed in the eighth connecting pipe 49i on the outlet side of the one-side vacuum vessel 40, and the temperature of the cold water flowing through the outlet side of the one-side vacuum vessel 40 is set. The measured temperature signal is transmitted to the roots pump as the compressor 43 through the control line 60. Then, by controlling the operation of the compressor 43, the temperature of the cooling water on the outlet side of the one-side vacuum vessel 40 is controlled to a predetermined value, for example, 15 (° C.).

The cooling / heating load 56 is composed of a perimeter load 56a and an interior load 56b in the living room 55, and a pipe 61e is connected between the two.
The perimeter portion load 56a is piped mainly on the outer peripheral portion or the outer wall portion of the building or the building, and the interior portion load 56b is mainly piped on the inside or the inner wall portion of the building or the building. Become.
The perimeter unit load 56a and the interior unit load 56b are composed of a radiating panel or the like, for example, a steel pipe or a resin pipe is formed in a coil shape and integrated with a metal plate such as an iron plate, and ceiling material. Configure as.
In the figure, 53a to 53e are third to seventh thermometers (T3 to T7), and 61f to 61h are valves. The above-described valves 61a to 61h are constituted by two-way valves or manual valves. In FIG. 3, the other constituent members are substantially the same as those shown in FIG.

Next, based on FIG. 3, the operation | movement of the summer of Example 1 of the air-conditioning system by the water vapor compression refrigerator which concerns on this invention, ie, the air_conditionaing | cooling operation, is demonstrated.
In the water vapor compression refrigerator C, during the summer operation, that is, the cooling operation, the one side vacuum vessel 40 operates as an evaporator, and the other side vacuum vessel 41 operates as a condenser.
Thus, the steam flows from the one side vacuum vessel 40 through the connection pipe 42 (duct), and flows in the root pump as the activated compressor 43 in the direction indicated by the arrow P1 (from the top to the bottom) It flows into the condenser as the other side vacuum vessel 41. And the water of the said one side vacuum container 40 is cooled, and cold water is manufactured. As described above, the evaporated water vapor is sent to the other-side vacuum vessel 41 by the compressor 43, that is, the Roots pump, and the other-side vacuum vessel 41 is heated.

On the other hand, by driving the pump 46a, the heat source water 46 such as well water is pumped, and the heat source water 46 flows in the primary connection pipe 48 in the direction indicated by the arrow P13, and the primary side 47a of the heat exchanger 47 And the three-way valve 52 is driven to reduce and flow again to the ground of the ground D. The three-way valve 52 opens the valve, and a part of the heat source water 46 is also sent to the branch connecting pipe 51 in the direction indicated by the arrow P14. Then, for example, 16 (° C.) heat source water 46 is pumped into the primary connection pipe 48 and the branch connection pipe 51 in the input portion connected from the pump 46 a to the primary side 47 a of the heat exchanger 47. Further, for example, 21 (° C.) heat source water 46 flows from the primary side 47 a of the heat exchanger 47 to the three-way valve 52, and for example, 16 (° C.) heat source water 46 flows in the branch connection pipe 51. And returned to the basement.

The heat exchanger 47 passes through the first connecting pipe 49a, the three-way valve 52a and the second connecting pipe 49b connected to the secondary side 47b to the other side vacuum vessel 41, that is, the input side as a condenser. The cooling water is fed in the direction of arrow P15 so that the cooling water is injected into the container by the injection nozzle 41a, and the temperature of the cooling water is, for example, 17 (° C.). At this time, the sixth connecting pipe 49f is closed, and cooling water does not flow through this. The other-side vacuum vessel 41 has, for example, a cold water temperature of 22 (° C.) and a saturated vapor pressure of about 2.65 (KPa), and the valve 61b is opened from the outlet side of the cold water pump. 50a causes the cooling water to flow in the directions of arrows P16 and P17. At this time, the temperature of the cooling water fed from the outlet side of the other vacuum vessel 41 is measured by the first thermometer 53 (T1) installed in the third connecting pipe 49c, and this measured temperature signal is the control line 54b. Is transmitted to the three-way valve 52a. The three-way valve 52a controls the opening degree of the valve so that the outlet temperature of the cooling water always becomes a predetermined value of, for example, 22 (° C.).
In addition, it can replace with the said three-way valve 52a, and can be set as the same structure and operation | movement by arrange | positioning two two-way valves. That is, each two-way valve is disposed in each of the first connecting pipe 49a and the fourth connecting pipe 49d connected to the secondary side 47b of the heat exchanger 47. And the temperature of the cooling water sent from the outlet side of the other side vacuum vessel 41 is measured by the first thermometer 53 (T1) installed in the third connecting pipe 49c, and this measured temperature signal is transmitted by the control line 54b. Transmitted to each two-way valve. Each two-way valve controls the opening degree of the valve so that the outlet temperature of the cooling water always becomes a predetermined value of, for example, 22 (° C.).

However, the cooling water is sent to the secondary side 47b of the heat exchanger 47, the first connecting pipe 49a, the three-way valve 52a, the second connecting pipe 49b, the other side vacuum vessel 41 and the cold water pump 50a, and on the other hand, the fourth side. It is circulated and sent to the connecting pipe 49d, the valve 61a, the three-way valve 52a and the second connecting pipe 49b, and on the other side to the valve 61b, the fifth connecting pipe 49e and the secondary side 47b of the heat exchanger 47.
Thus, when the temperature of the cooling water sprayed from the spray nozzle 41a is 17 (° C.) and the outlet temperature thereof is 22 (° C.), the temperature difference becomes 5 (° C.), and the temperature difference is further reduced. If the temperature is 5 (° C.) or higher, the amount of cooling water flowing through the cold water pump 50a can be reduced, the power of the cold water pump 50a can be reduced, and energy consumption can be taken.

Thus, the refrigeration operation can be performed by cooling the other-side vacuum vessel 41 with the heat source water 46 such as well water. Then, chilled water is circulated and circulated into the one side vacuum vessel 40, that is, the load side connecting pipe which is the chilled water pipe as the secondary side loop of the steam compression refrigerator C connected to the evaporator, thereby cooling the cooling / heating load 56. . Then, the interior of the living room 55 is cooled by the summer operation of the steam compression refrigerator C, that is, the cooling operation.
Here, the cold water temperature of the one side vacuum vessel 40, that is, the outlet side of the evaporator is, for example, 15 (° C.), the valve 61d is closed, and the cold water is not sent to the tenth connecting pipe 49j. The hot water pump 58a flows in the ninth connecting pipe 49i in the direction of the arrow P18. The cold water flows in the directions indicated by arrows P19 and P20 into the perimeter load 56a and the eleventh connecting pipe 49k through the cooling / heating load 56, that is, the interior load 56b and the valve 61e with the valve opened. To do. Then, the cold water is flowed in the direction of arrow P21 via the three-way valve 52b through the seventh connecting pipe 49g, and is injected by the injection nozzle 40a provided in the one-side vacuum vessel 40. To stream.
The valves 61f, 61g, and 61h are closed so that the flow circuit from the interior portion load 56b to the fourth connection pipe 49d and the flow circuit from the perimeter section load 56a to the ninth connection pipe 49i are provided. Is cut off.
In addition, it can replace with the said three-way valve 52b, and can be set as the same structure and operation | movement by arrange | positioning two two-way valves. That is, a two-way valve is provided in each of the eleventh connecting pipe 49k and the sixth connecting pipe 49f. The valve opening degree of the two-way valve connected to the sixth connecting pipe 49f is closed.

Thus, for example, 15 (° C.) cold water is fed from the outlet side of the one-side vacuum vessel 40 to the interior portion load 56b and the perimeter portion load 56a, and the interior portion load 56b, for example, 15 (° C.). For example, a cooling temperature of 16.5 (° C.) can be secured in the remeter unit load 56a. Then, for example, 18 (° C.) cold water is discharged from the perimeter unit load 56 a, and for example, 18 (° C.) cold water is injected from the injection nozzle 40 a disposed in the one-side vacuum vessel 40. The one side vacuum container 40, that is, the inside of the evaporator has a saturated vapor pressure of, for example, 1.71 (KPa), and cold water of 15 (° C.) can be taken out by the hot water pump 58a. The temperature signal measured by the second thermometer 59 (T2) is transmitted to the compressor 43, that is, the Roots pump through the control line 60, and the operation of the compressor 43 is controlled. Then, the operation of the compressor 43 is controlled in accordance with the load amount of the cooling / heating load 56 so as to ensure the measured temperature value of the second thermometer 59 (T2) at a constant temperature.

Thus, the first embodiment of the cooling and heating system using the steam compression refrigerator according to the present invention controls the flow direction of steam to the compressor 43, that is, the roots pump, without arranging a number of unique switching valves in summer. By doing so, the operating efficiency (COP) of the steam compression refrigerator C can be increased, and a suitable refrigerant can be flowed to the cooling / heating load 56, and the cooling function of the living room 55 can be achieved.
The compressor 43, that is, the Roots pump, uses an inverter or the like according to the cooling / heating load 56. Control the capacity. Further, the hot water pump 58a is controlled and adjusted so that the measured temperature difference between the fourth thermometer 53b and the seventh thermometer 53e is, for example, 3 (° C.) using a separate inverter. Further, the three-way valve 52 transmits a temperature signal measured by a third thermometer 53a (T3) disposed in the first connection pipe 49a to the three-way valve 52 via a control line 54a. In order to bring the temperature of the cooling water flowing through 49a close to the temperature of the heat source water 46 flowing into the primary connection pipe 48, for example, the heat source water 46, that is, the total amount of well water is transferred to the heat exchanger 47. And is controlled to about 17 (° C.).

Next, based on FIG. 3, the winter of Example 1 of the air-conditioning system by the steam compression refrigerator which concerns on this invention, ie, the operation | movement of heating operation, is demonstrated.
In the steam compression refrigerator C, the one-side vacuum vessel 40 operates as a condenser and the other-side vacuum vessel 41 operates as an evaporator during a winter operation, that is, a heating operation.
Thus, the water vapor flows from the other side vacuum vessel 41 through the connection pipe (duct) and flows through a roots pump as the compressor 43 that is started up, and flows in the direction indicated by the arrow P7 (from below to above). It flows into the condenser as 40. And the water of the said one side vacuum container 40 is heated, and warm water is manufactured.

On the other hand, by driving the pump 46a, the heat source water 46 such as well water is pumped, and the heat source water 46 flows in the primary connection pipe 48 in the direction indicated by the arrow P13, and the primary side 47a of the heat exchanger 47 And the three-way valve 52 is driven to reduce and flow again to the ground of the ground D. The three-way valve 52 opens the valve, and a part of the heat source water 46 is also sent to the branch connecting pipe 51 in the direction indicated by the arrow P14. Then, for example, 16 (° C.) heat source water 46 is pumped into the primary connection pipe 48 and the branch connection pipe 51 in the input portion connected from the pump 46 a to the primary side 47 a of the heat exchanger 47. Further, a heat source of, for example, 13 (° C.) is provided in the primary connection pipe 48 from the primary side 47a of the heat exchanger 47 to the three-way valve 52 and in the output portion piped for reduction to the underground from the three-way valve 52. Water 46 is flowed and reduced.

The heat exchanger 47 passes through the first connecting pipe 49a, the three-way valve 52a and the second connecting pipe 49b connected to the secondary side 47b to the other side vacuum vessel 41, that is, the input side as an evaporator. The cooling water is flowed in the direction of the arrow P15 so as to be injected into the container by the injection nozzle 41a, and the temperature of the cooling water is, for example, 15 (° C.). At this time, the other-side vacuum vessel 41 has, for example, a cold water temperature of 12 (° C.) and a saturated vapor pressure of about 1.40 (KPa), and the valve 61b is opened from the outlet side thereof. Cooling water is sent in the directions of arrows P16 and P17 by the pump 50a. At this time, the temperature of the cooling water fed from the outlet side of the other vacuum vessel 41 is measured by the first thermometer 53 (T1) installed in the third connecting pipe 49c, and this measured temperature signal is the control line 54b. Is transmitted to the three-way valve 52a. The three-way valve 52a controls the opening of the valve so that the outlet temperature of the cold water always becomes a predetermined value of 12 (° C.), for example.

However, the cooling water is sent to the secondary side 47b of the heat exchanger 47, the first connecting pipe 49a, the three-way valve 52a, the second connecting pipe 49b, the other side vacuum vessel 41 and the cold water pump 50a, and on the other hand, the fourth side. It is circulated and sent to the connecting pipe 49d, the valve 61a, the three-way valve 52a and the second connecting pipe 49b, and on the other side to the valve 61b, the fifth connecting pipe 49e and the secondary side 47b of the heat exchanger 47.

Thus, the refrigeration operation can be performed by heating the one-side vacuum vessel 40 with the heat source water 46 such as well water. Then, hot water is circulated in the load side connecting pipe, which is a cold / hot water pipe as a secondary loop of the steam compression refrigerator C connected to the condenser on the one side, that is, the heating / cooling load 56.

Here, the one side vacuum vessel 40, that is, the outlet side of the condenser, has a hot water temperature of 30 (° C.), for example, and the valve 61d is closed and the hot water is not sent to the tenth connecting pipe 49j. The hot water pump 58a flows in the ninth connecting pipe 49i in the direction of the arrow P18. Then, the hot water flows in the directions indicated by the arrows P19 and P20 into the perimeter load 56a and the eleventh connecting pipe 49k via the cooling / heating load 56, that is, the interior load 56b and the valve 61e. Then, the hot water flows in the direction of arrow P21 via the three-way valve 52b through the seventh connecting pipe 49g, and is jetted by the jet nozzle 40a provided in the one-side vacuum vessel 40.

For example, the heating temperature of 28.5 (° C.) can be ensured in the remeter unit load 56a. Then, for example, 27 (° C.) warm water is discharged from the perimeter unit load 56 a, and for example, 27 (° C.) warm water is injected from the injection nozzle 40 a disposed in the one-side vacuum vessel 40. The one-side vacuum vessel 40, that is, the inside of the condenser has a saturated vapor pressure of 2.65 (KPa), for example, and 30 (° C.) hot water can be taken out by the hot water pump 58a. The temperature signal measured by the second thermometer 59 (T2) is transmitted to the compressor 43, that is, the Roots pump through the control line 60, and the operation of the compressor 43 is controlled. Then, the operation of the compressor 43 is controlled in accordance with the load amount of the cooling / heating load 56 so as to ensure the measured temperature value of the second thermometer 59 (T2) at a constant temperature.

Thus, the first embodiment of the cooling and heating system using the steam compression refrigerator according to the present invention controls the flow direction of steam to the compressor 43, that is, the roots pump, without arranging a number of unique switching valves in winter. By doing so, the operating efficiency (COP) of the steam compression refrigerator C can be increased, and hot water suitable for the cooling / heating load 56 can be flowed to fulfill the heating function of the living room 55.
The compressor 43, that is, the Roots pump, uses an inverter or the like according to the cooling / heating load 56, and supplies warm water to ensure that the cooling / heating load 56 is maintained at a predetermined temperature, that is, 27 (° C.) to 30 (° C.). Control the capacity. Further, the hot water pump 58a is controlled and adjusted so that the difference in temperature measured by the fourth thermometer 53b and the seventh thermometer 53e is, for example, 3 (° C.) using a separate inverter. Further, the three-way valve 52 transmits a temperature signal measured by a third thermometer 53a (T3) disposed in the first connection pipe 49a to the three-way valve 52 via a control line 54a. In order to bring the temperature of the cooling water flowing through 49a close to the temperature of the heat source water 46 flowing into the primary connection pipe 48, for example, the heat source water 46, that is, the total amount of well water is transferred to the heat exchanger 47. And is controlled to about 15 (° C.).
