Description

[Technical Field] The present invention is a technique related to the structure of a cooling device under no wind in a building and a heat absorption method used therefor.
The term “no wind” as used herein refers to a state in which wind does not blow in the building in a substantially horizontal direction (air does not move strongly in the horizontal direction).

  The reason that competitions such as badminton and table tennis are performed indoors according to international regulations is that the influence of wind cannot be avoided outdoors during competition. However, it is extremely difficult to cool a building in which badminton or table tennis is played without wind. Similarly, in a cleaning factory where a bar code tag is attached to the laundry and managed by a computer, the room must be in a windless state as well. Other facilities such as asthma due to allergies in general housing, research facilities that dislike dust soaring, and broadcasting facilities that most dislike wind noise from microphones need to be air-cooled as well. .

  As a cooling device for indoor cooling that is generally used, a fan or blown air volume is controlled in a heat absorber having fins in contact with a metal pipe that passes gas or water as a refrigerant to increase the heat absorption area. The temperature inside the room is lowered by blowing cool air that is blown by cool air that is cooled by heat conversion, and air-cooled and water-cooled heat pump air conditioners are common.

  Generally, an indoor unit has a heat absorber and a fan, and an outdoor unit has a compressor, a condenser, and a cooling fan, usually called an outdoor unit, and an air conditioner that adjusts the indoor temperature via a refrigerant. The method of carrying cool air with wind is not suitable for cooling in a windless state because it is necessary to use a powerful wind to send the wind farther as the building is larger, various inventions to realize this Has been proposed, but there is no effective method. Japanese Patent Laid-Open No. 10-300137 also shows an example using an aluminum plate, but it has not been put into practical use. Japanese Patent Laid-Open No. 2000-28167 proposes a structure in which a venturi is provided to move air in a large building. However, until the invention of the non-air-cooling method was finally invented in Japanese Patent Application No. 2013-261920, the cooling efficiency under no-air conditions However, there was nothing that allowed cooling using a good and economical gas.

The present invention seeks to provide a structure of a device that enables cooling without wind in a building. The term “no wind” as used herein means that no horizontal wind is generated inside the building. Furthermore, the present invention has an endothermic effect due to the movement of the gas according to the size of the target room because the endothermic effect differs between the gas inlet and outlet of the target space when using a non-air-cooling device using gas. Need to be made uniform. The cooling apparatus according to the present invention has a structure of an apparatus that can facilitate installation work and a production system, and can reduce the room temperature to be cooled in a short time.

The inventor of the present invention paid attention to cooling by air subsidence (descent) action in which cold air has lower specific gravity than warm air and falls down. For this purpose, install as many refrigerant pipes with fins that are processed so that the refrigerant pipes fit in the dew condensation receiver near the ceiling if necessary, and cool the air using the action of falling naturally down. I decided to do it.
That is, the heat absorption means 2 is provided in the upper part of the partitioned space 1a to be cooled, the heat absorption means 2 is provided with the refrigerant pipe 3 and the condensed water receiving means 5 in the lower part thereof, and the heat exhaust means 10 is provided in addition to the space 1a. This is a windless cooling device in a windless state in a building in which cooling is performed by natural descent of the cool air in the upper part of the space 1a in which the heat absorbing means 2 is provided. The heat absorbing means is characterized in that the outer periphery of the refrigerant pipe is covered with a member having fins, and this apparatus using gas as the refrigerant is controlled to the extent that frost is peeled off because frost adheres to the refrigerant pipe. Remove the frost by applying light wind to the fins. The cold air overflowed from the dew condensation water receiver, and it was possible to cool the building without wind in the natural descent.

In the present invention, the heat absorbing means 2 is provided in the upper part of the partitioned space 1a of the cooling object 1, and the heat absorbing means 2 is obliquely below the fins 4a arranged in the refrigerant pipe 3 and the lower part thereof, or in the mententry surrounding the refrigerant pipe 3. A heat absorption system equipped with air pipes 6 on both sides and surrounded by refrigerant pipe 3, fins 4a, and air pipe 6 with U-shaped condensed water receiving means 5 is provided with heat exhaust means 10 in addition to space 1a. The heat-absorbing means 2 is arranged so that the fins 4a arranged in a shinmentley surrounding the refrigerant pipe 3 are attached so that the refrigerant pipe 3 reciprocates around the center of the fin 4a and heat is converted. Controls the strength of the wind that comes out, so that a natural fall occurs, and the louver 6b installed above the fin 4a passes through the condensation water receiver so that it exits the condensation water receiver. To the natural descent of the cool air in the upper space Ri is an overview of the cooling device under windless conditions in the building to perform cooling.
In an indoor unit of a non-cooled air conditioner, air pipes that are installed diagonally on both sides of the bottom of the dew condensation water receiver are arranged at intervals of 3 mm to 10 mm with high thermal conductivity fins that match the volume of the dew condensation water receiver in the shape of a U-shaped groove. Install so that the fins stop at the top, drill one or more pairs of holes with two holes into which the refrigerant pipe can be inserted, install the refrigerant pipe into the return and return holes, A structure of a windless cooling device in which air pipes are attached to the lower left and right sides of the fins, and air is blown obliquely symmetrically toward the gaps between the fins and the refrigerant pipes so that the refrigerant pipes are not frosted from both the left and right sides.
The present inventor has focused on cooling by air subsidence (descent) action in which cold air has a higher specific gravity than warm air and falls downward. For that purpose, the necessary number of finned refrigerant pipes 4 having fins 4a spirally wound around the refrigerant pipe 3 through which the refrigerant is passed is installed near the ceiling as necessary, and the cold air naturally uses the action of descending downward. Cooling was performed.
That is, the heat absorption means 2 is provided in the upper part of the partitioned space 1a of the cooling object 1, the heat absorption means 2 includes the refrigerant pipe 3 and the dew condensation water receiving means 5 in the lower part, and the exhaust heat means 10 is provided in addition to the space 1a. A heat-absorbing means and a heat-absorbing method in which no air is cooled in the building in which the air is cooled by the natural descent of the cool air in the upper part of the space 1a and the apparatus used therefor.

Further, in the present invention, the heat absorbing means 2 is provided in the upper part of the partitioned space 1a of the cooling object 1, and the heat absorbing means 2 is below the refrigerant pipe 3 and its lower part or the fins 4b arranged in the mententry surrounding the refrigerant pipe 3. In addition to the space 1a, the heat exhausting means 10 is provided in an endothermic system equipped with air pipes 6 on both sides and surrounded by the refrigerant pipes 3a, fins 4a, and air pipes 6 with a U-shaped condensed water receiving means 5. The heat absorption means 2 is a refrigerant in which the flat surfaces of the gas inlet refrigerant pipe 3a and the outlet 3b are formed by a semi-cylindrical fin 4b arranged in a cinimentary surrounding the refrigerant pipe 3a. The refrigerant pipe 3a whose adhesive surface is shortened so that the refrigerant passes through the part where it is folded back is installed so as to reciprocate near the center of the fin 4a so as to convert heat, and the strength of the wind from the air pipe 6 is increased. Control and natural descent The cooler that has passed through between the fins 4a and is provided with the louver 6b installed at the upper part so that the cold air from the dew condensation water receiver comes out of the dew condensation water receiver is cooled by the natural descent of the upper air in the space. It is the outline | summary of the air_conditioning | cooling apparatus in the windless state in the building made to perform.
The refrigerant pipes have the same quality and the same dimensions, and two sets of two semi-cylindrical pipes are bonded together, and the respective plane portions are bonded to form one cylinder. Adhered kamaboko-shaped refrigerant pipes, one for the inlet side and the other for the outlet side, allow the refrigerant to be folded back, so that the end part of the cylindrical refrigerant pipe is closed with a lid with a space inside. The structure of the heat absorbing device according to claim 1, wherein the gas inlet and outlet adhesive surfaces may be vertical, and the cylinder cross section is a sector and the refrigerant pipe is divided into four parts. In the place where the refrigerant can be reciprocated twice and turned up, a lid with a space is provided, and the structure of the heat absorption device in which the refrigerant reciprocates twice and returns to the outlet can level the heat absorption. In addition, if a refrigerant pipe having a multiple of 2 is used using a honeycomb structure, the refrigerant can be reciprocated three or more times.

In order to perform airless cooling more effectively, it is possible to level the temperature of the air cooled by the refrigerant and increase the efficiency of the cooling by adopting a structure in which the refrigerant pipes are in contact with a plurality of sets of fins.
The biggest drawback of the refrigerant pipe having a structure in which the cooling is performed with the one-way refrigerant pipe is that the refrigerant temperature is unstable and there is a temperature difference between the inlet and the outlet. In order to eliminate this drawback, the temperature can be leveled by bringing the inlet and outlet into contact with each other as a U-shaped hairpin structure, and several sets of refrigerant piping having a U-shaped hairpin-like structure are used as fins. A temperature leveling effect can be achieved by contact.
The material of the air pipe 6 may be easily processed vinyl chloride resin or metal, and instead of the slit 6a, the wind hits the fin 4a through a small hole 6b according to the pitch of the fin 4a of the finned refrigerant pipe 4, or By making it pass between the fin 4a and the fin 4a, thermal conversion becomes a large value. In this case, the shape of the air pipe 6 through which air passes may be round, participating, or polygonal. In this case, in order to manufacture the hole 6b, a slit 6a having a width of several millimeters is provided in parallel with the air pipe 6, and the slit 6a is partially blocked with an adhesive tape such as aluminum foil, aluminum tape, paper tape or cloth. The hole 6b can be easily made by providing a hole having a required size.

As a specific device, heat absorption means is provided in the upper part of the space to be cooled, and the heat absorption means includes refrigerant pipes in contact with the fins, air pipes and U-shaped dew condensation receiving means on the diagonally lower sides thereof. In addition to the space of the heat absorption means provided with a louver slightly smaller than the U-shaped dew condensation water receiver above the fins, a heat exhaust means is provided, and the heat absorption means is a member having fins and has a plurality of fins and a refrigerant pipe Is a cooling device characterized in that a fin is reciprocated through a refrigerant pipe having an appropriate length.
The refrigerant pipe is formed in a hairpin shape, and the refrigerant pipe is reciprocated for the purpose of leveling because the temperature of the refrigerant passing through the refrigerant pipe is different between the inlet and the outlet. It was set as the structure which put the fin of high heat conductivity through the made refrigerant piping. Further, in order to level the temperature, the cold air can be leveled by bringing a plurality of sets of refrigerant pipes into contact with a common fin.

  In order to further compensate for the disadvantage that the temperature near the inlet of the refrigerant pipe and the temperature near the outlet are not the same, which is the only point to cool the gas as refrigerant by integrating the hairpin structure refrigerant pipe, the refrigerant pipe has a kamaboko shape. As a semi-cylinder, a flat portion is brought into close contact with each other, and heat conversion can be efficiently performed in a shape in which fins arranged in a flat plate are skewered. By attaching a hollow cap so that the refrigerant can pass through the folded portion of the kamaboko refrigerant pipe, the inlet and outlet of the refrigerant pipe are in close contact with each other, and the temperature difference is minimized.

Cooling by natural subsidence of cold air, but in order to perform a greater heat conversion, air pipes are provided at either or both ends of the lower part in all directions around the refrigerant pipe, and slant of the finned refrigerant pipe extending straight or curved From the bottom, open slits and countless holes in the upper part of the air pipe installed in parallel with the air pipes at both ends or the finned refrigerant pipe, or in the direction in which the wind hits the refrigerant pipe. A small amount of wind that blows off the cold air from the finned refrigerant pipe is blown toward the fins. At this time, air is blown by controlling the strength applied to the fin so as not to affect the windless state from the floor to the height where the windless state is required.

The material of the above air piping may be vinyl chloride resin or metal, which is easy to process, and as a single unit with a dew condensation water receiver for manufacturing, a small hole is made to fit the pitch of the fin passing through the refrigerant piping instead of the slit. By making it hit a fin or passing between fins, the heat conversion becomes a larger value. In this case, the shape of the air pipe through which air passes may be round, triangular, or polygonal. In this case, a few millimeters wide slit is opened in parallel with the air pipe, and the slit is partially closed with adhesive tape such as aluminum foil, aluminum tape, paper tape, cloth, etc. It is also possible to make holes easily by providing holes.
Next, the necessary number of separated compressors 10a are collectively stored in the compressor chamber 30, and the compressor 10a also becomes hot during operation, so the compressor chamber indoor unit 10c is attached to the compressor chamber 30. In this case, the compressor room indoor unit 10c is cooled by wind with a general heat sink and fan set, and the compressor room condenser 10e is cooled in the same water tank 20 as the other condensers 10b. Do it.

Also, several refrigerant pipes with fins installed near the ceiling are used as one set, and a drain pan that receives the air pipe and condensed water is set at the lower part of the refrigerant pipe to form one collective heat absorption unit. Make it possible. For this reason, providing a finned refrigerant pipe connection port, an air pipe connection port, and a drain pan connection port in the collective heat absorption unit facilitates cooling of a large building.

When using groundwater veins, the groundwater is drawn up from several meters to several hundred meters, and the water stored in the above or below water tank 20 is used. The flow is constant by hot water converted by heat by a pump or natural convection. When the temperature is reached, a necessary amount of hot water can be stored in a separately provided three-way valve 41 and hot water storage tank 40 and used for a shower or a bath. The hot water is not used, or the remaining hot water storage tank 40 is returned to the basement again. At this time, the groundwater supply pipe 26a buried in the basement on the water supply side and the groundwater return pipe 27a returned to the basement are used. The depth is returned to the underground groundwater vein B25 different from the groundwater vein A24 to be pumped. By returning the water vein to a different water vein, it is possible to prevent the loop from being made with the same water vein, and depending on the water vein, there is a case where the pressure of the groundwater vein is in the groundwater vein, so it is necessary to surely return to the underground By providing the groundwater return pressure pump 27b, it can be forcibly returned to the underground. Although this thought can be seen in Japanese Patent Application Laid-Open No. 2006-234229, the treatment of water that has been cooled using a groundwater source and has reached a high temperature after cooling is simply a return to the original groundwater source. As a result, the plurality of condensers 10b can be simultaneously cooled without using any air, so that a rise in temperature on the ground can be prevented and ground subsidence caused by pumping up groundwater can also be prevented. If it is unavoidable to return to this underground, it is possible to return to the same water vein at a certain distance.

In addition, the structure and method of installing the condenser 10b so as to be completely submerged in a plurality of water tanks 20 and cooling with groundwater can be used for outdoor units that use a large building or wind to blow cool air and warm air with a fan, In addition to preventing urban heat island phenomena, a three-way valve is installed in a so-called outdoor unit with a normal compressor, condenser, and fan to provide hot air and cool in groundwater during the summer. In winter, air cooling using a fan can return cold air to the ground, which helps to prevent global warming.Of course, the method of heat conversion only with groundwater is energy saving because the groundwater has a constant temperature. It can also contribute to saving gas emissions. Also, by using groundwater, the cooling temperature of the condenser becomes constant, and cooling can be performed efficiently even in countries and regions where the average temperature exceeds 40 degrees.

In the present invention, when the finned refrigerant pipe 4 or the metal flat plate heat-absorbing material 8c cooled by the low-temperature refrigerant is converted into heat in the respective heat-absorbing devices indoors, the minimum necessary wind is required to cool the indoors in a windless state. The air is blown through the slit 6a or the small-diameter hole 6b from the immediate vicinity, and after cooling with the finned refrigerant pipe 4 or the metal flat plate heat-absorbing material 8c once blown to the upper part or the periphery, A cooling device in the state can be made.
Further, in order to make the air flow uniform, the size of the hole 6b can be solved by increasing the size of the hole 6b toward the tip, while the front direction is small.

  In this case, condensed water is generated when the cold air is converted into heat. However, the condensed water generated by the drain pan 5a by disposing the drain pan 5a directly below the finned refrigerant pipe 4 and the air pipe 6 or the lowermost part of the metal flat plate heat absorbing material 8c. In order to prevent this, it can be solved by attaching a chemical substance such as rubber or urethane or a natural dew condensation prevention material 5b to the inside or outside of the drain pan 5a. The drain pan 5a can be replaced with a commercially available gutter.

  The air pipe for passing air according to the present invention may be an air pipe that is attached so that air strikes the refrigerant pipe obliquely on both sides of the refrigerant pipe and the U-shaped drain pan, or that is integrally molded with the U-shape. The air pipe installed at the corner could be solved by adhering to the drain pan so that the direction of the wind did not change. The starting point from which the wind of the air pipe 6 is blown is divided into several air pipes 6 so that the positions of the starting points of the slits are dispersed in several places, thereby making it easy to achieve uniform air flow.

  The compressor 10a, the condenser 10b, and the fan of the cooling device are removed, and the compressor 10a is stored in one room. Since the compressor 10a of the compressor chamber 30 is at a high temperature, a compressor chamber indoor unit 10c for cooling the compressor 10a is disposed, and a compressor chamber condenser 10e for cooling the compressor chamber 30 is disposed inside the building. By cooling in the same water tank 20 as the condenser 10b to be cooled, high temperature air is not emitted from any of the outdoor unit and the entire cooling unit of the indoor unit, and it is cooled by ground water and prevention of surrounding weather warming. Thus, since the heat conversion of the condenser 10b is made highly efficient, the power consumption is reduced.

  According to the present invention, it is possible to perform cooling in a building where badminton and table tennis are performed in a windless state. In addition, even in a cleaning factory where a bar code tag is attached to the laundry and managed by a computer, the room can be made airless as well, so that the computer can be managed. In addition, research facilities that dislike dust soaring can now be air-cooled.

  In the present invention, the finned refrigerant pipe 4, the drain pan 5a, the dew condensation preventing material 5b, the air pipe 6 and the like are used as the collective heat absorption unit 7, and the metal flat plate heat absorbing material 8c, the drain pan 5a, the air pipe 6, the high thermal conductivity filler 8b and the like are used. By unitizing the flat plate heat absorption device 8, the construction efficiency, the cooling efficiency, etc. are improved, and the construction area corresponding to the size can be easily adapted.

  Since the cooling of the refrigerant, usually called an outdoor unit, is usually performed by using air, the temperature of the surrounding air has risen. However, particularly in large facilities, a plurality of condensers 10b are cooled. Therefore, it is possible to efficiently cool the high-temperature refrigerant by immersing these condensers 10b in the underground water stored in the water tank 20 installed underground or on the ground at a time to cool the condenser 10b. It has an effect suitable for the environment, such as prevention.

  When the refrigerant called an indoor unit or outdoor unit is cooled to cool the air-conditioning target space 1a, the indoor temperature sensor 51 and the outside air temperature sensor 52 are used for temperature management. The heat absorbing means 2 of the present invention is separated from the compressor 10a and the condenser 10b. The cooling target space 1a, the output control means of the compressor 10a according to the outdoor temperature, the flow control means of the air sent to the air pipe 6, and the water tank By storing the electric control means 50 of the entire cooling device in the compressor chamber 30 in which the temperature can be managed by a signal from the temperature sensor 53 for managing the temperature of the water in the water 20, the influence of the outside air temperature, dust and the like is eliminated. I can do it.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an overall view of an apparatus used in the windless air conditioning method of the present invention.
As seen in this example, the present invention is provided with heat absorbing means in the upper part of the partitioned space of the air-cooled object, the heat absorbing means is provided with a refrigerant pipe and dew condensation water receiving means in the lower part, and the ceiling surface of the heat absorbing device Attach a louver to disperse the cold air at the top of the U-shaped drain pan. At this time, the louver is made smaller than the inner diameter of the U-shaped dew condensation water receptacle so that it will fall to the dew condensation water receiver even if it falls due to the condensation water adhering to the louver.
Exhaust heat means is provided in a place other than the space, and the space that does not like wind like badminton is cooled by natural descent of the cool air in the upper part of the space where the heat absorption means is provided. As a result, the air conditioner can be cooled under no wind conditions.
In addition, when used in ordinary houses and buildings with low ceiling heights, the louver is placed on the top of the condensed water receiver so that the separated cold air does not directly hit the ceiling surface.

Therefore, the cooling device includes a refrigerant pipe and a drain pan as a dew condensation water receiving means at the lower part thereof as shown in FIG. In addition to this space, exhaust heat means is provided as a condenser and a compressor. As shown in FIG. 3, the heat absorbing means is characterized in that the outer periphery of the refrigerant pipe through which the refrigerant passes is covered with a member having fins, and the refrigerant pipe is not one-way but is in contact with the fins and reciprocates one loop. It is a heat sink with set.

In heat absorption devices that use gas as a refrigerant, heat conversion is significant, so in refrigerant piping installed in one way, the temperature of the air near the inlet of the refrigerant is lower than the temperature of the air near the outlet. The resulting cooling effect in the room also produces spots. In order to eliminate this instability, the refrigerant piping was reciprocated and the heat conversion of the fins was leveled by performing the heat conversion twice through the refrigerant in the reverse direction through the fins. In a practical machine, leveling can be further achieved by reciprocating twice. Furthermore, in order to equalize the refrigerant temperature of the refrigerant pipe, a structure in which the heat absorption fins having a high heat transfer rate are received by the air pipe so as not to land on the condensed water receiver.
Further, the flat portions of the kamaboko-shaped refrigerant pipes can be bonded together to equalize the refrigerant temperature directly between the refrigerant pipes. At that time, by making the refrigerant pipe into a fan shape, the pipe length becomes two reciprocations, and further, leveling and heat conversion become large.

Open one or two or more pairs of holes that allow the refrigerant piping to be inserted into the fins with high thermal conductivity that matches the volume of the dew condensation receiver, and use the refrigerant piping as the return and return holes. Install. Further, triangular air pipes are attached to the left and right sides of the fins, and a wind controlled so as to separate the cold air from both the left and right sides is blown obliquely toward the gaps of the fins and the refrigerant pipes. By blowing from the left and right, the winds rise upwards and are separated by louvers provided above the dew condensation water receiver, and the cold air is pushed out to the left and right, creating a gentler wind and making it easy to create a windless state (natural fall of cold air) No wind cooling effect can be achieved even if the air volume is increased.
At this time, the air blown out from the air pipe can be purified by using air cleaned by an air purifier and can be used in hospital rooms or precision machine rooms.

  The air pipe and the dew condensation water receiver are integrated, and a right-angled triangular air pipe with an angle of approximately 15 to 60 degrees is attached to the left and right sides of the fin with respect to the fin. Spray diagonally toward the pipe. The air piping structure according to claim 1 or 2, wherein the air outlet of the air hole or slit is raised by 1 to 5 mm so that the condensed water adhering to the refrigerant piping or the fin does not enter the air piping. .

Although the principle is self-evident, the wind passing through the gaps of the fins in the air blower arranged in Sinmentry interferes with each other and tends to move upward. At this time, since the fin becomes a wall and further determines the direction of the wind, the wind and the wind collide with each other, so that the cool air can be efficiently realized by naturally falling toward the open surface, that is, upward. In an indoor unit of a non-cooled air conditioner, air pipes that are installed diagonally on both sides of the bottom of the dew condensation water receiver are arranged at intervals of 3 mm to 10 mm with high thermal conductivity fins that match the volume of the dew condensation water receiver in the shape of a U-shaped groove. Install so that the fins stop at the top, drill one or more pairs of holes with two holes into which the refrigerant pipe can be inserted, install the refrigerant pipe into the return and return holes, No air-cooling with a structure in which air pipes are attached to the left and right sides of the fins, and the air is blown diagonally symmetrically toward the gaps between the fins and the refrigerant pipe so that the cold air is peeled off from both the left and right sides to prevent frost from forming on the refrigerant pipe. The structure of the device. Furthermore, when frost is likely to be formed on the refrigerant pipe, a sensor that monitors the color of the refrigerant pipe is attached, and the controlled air is blown before the frost is attached to the refrigerant pipe, so that the cold air can be separated more efficiently. .

The refrigerant pipes have the same quality and the same size, and two pipes that are semi-cylindrical and semicylindrical are combined into one set, and the respective plane portions are bonded together to form one cylinder. Adhering kamaboko-shaped refrigerant pipes are one for the inlet side and the other for the outlet side. In order to fold the refrigerant, the end of the cylindrical refrigerant pipe is closed with a lid with a space inside, The structure of the endothermic device is such that the reciprocating member moves back and forth within the cylinder.
In addition, a louver is provided closer to the ceiling surface of the dew condensation water receiver, and the wind that hits the fin does not hit the ceiling.
Further, the refrigerant pipe divided into four sections with a cylindrical cross section is a single pipe, and the level of heat absorption of the heat absorption device can be leveled by one reciprocation by the refrigerant reciprocating twice.
The end portions of the three places where the refrigerant folds are combined so that two of the four fan-shaped ones are combined on the exit side and the entrance side, respectively, and the two are closed with a lid having a space inside, so that the refrigerant reciprocates twice in the cylinder. Endothermic device. Further, the refrigerant pipe is a honeycomb structure having a multiple of two, and two holes of the refrigerant pipe are combined on the outlet side and the inlet side, respectively, and closed with a lid having a space inside, and the refrigerant makes one or more reciprocations in the cylinder. This is the structure of the heat absorption device.

In the heat absorption means 2, an air pipe 6 having an opening toward the refrigerant pipe 3 is provided between the refrigerant pipe 3 and a drain pan 5 a as the condensed water receiving means 5.
The heat absorption means 2 has a plurality of collective heat absorption units composed of finned refrigerant pipes and air pipes above the drain pan, and has finned refrigerant pipe connection ports, air pipe connection ports, and drain pan connection ports with other collective heat absorption units. Good structure.

It can also be characterized that the condenser 10b is housed in the poured water tank 20. Groundwater return into the groundwater return pipe 27a of the groundwater return line 27 from the water tank 20 to the groundwater vein B25 in the groundwater supply pipe 26a of the groundwater supply line 26 to the water tank 20 from the groundwater vein A24. A pressurizing pump 27b is provided.
The groundwater vein B25 of the groundwater return line 27 is different from the groundwater vein A24 of the groundwater supply line 26 and has a shallow cooling efficiency when it is at a shallow position.
As shown in FIG. 1, when the compressor 10a and the electric control means 50 of a plurality of sets of air conditioners are housed in the compressor chamber 30 having a cooling function, the space is saved, the construction efficiency is good, and the influence of outside air temperature and dust It is also possible to reduce the probability of failure occurrence.

The compressor 10a and the condenser 10b are provided with connection members for connection with other devices.
A necessary number of finned refrigerant pipes 4 having fins 4a spirally wound around the refrigerant pipe 3 through which the refrigerant is passed is installed near the ceiling, and the finned refrigerant pipes 4 are cooled via the refrigerant. The minimum air necessary to peel off the cold air tightly attached to the attached refrigerant pipe 4 was ejected from the vicinity of the fin 4a through the slit 6a or the small-diameter hole 6b, and the air was once blown to the upper part or the periphery. After cooling with the finned refrigerant pipe 4 or the metal flat plate heat absorbing material 8c, one collective heat absorbing unit 7 is provided so that the necessary number of the finned refrigerant pipes 4 can be easily put together by a cooling system in which the cold air is not naturally winded. And a finned refrigerant pipe connection port 7b, an air pipe connection port 7c, and a drain pan connection port 7d for connecting condensed water, and a necessary number of collective endothermic units generated depending on the size of the building. 7 are linked to by the construction. The refrigerant that has been heat exchanged indoors is generally returned to the outdoor unit. As for the form of the outdoor unit, the fan 10 is removed, the compressor 10a and the condenser 10b are separated, the ground water or the ground water is stored in the water tank 20 where the condenser 10b is installed underground or on the ground, and the water stored in the water tank 20 is stored. The condenser 10b is submerged so as to be immersed. At this time, since it is necessary to cool a plurality of condensers 10b in a large-scale facility, these condensers 10b became high temperature by being submerged in the groundwater stored in the water tank 20 installed on the ground or on the ground at a time and cooled. The refrigerant can be efficiently cooled.
Groundwater to be cooled is prevented from forming a groundwater loop by returning the depth of the groundwater supply pipe 26a buried in the underground on the water supply side and the depth of the groundwater return pipe 27a returned to the ground to the groundwater vein B25 different from the groundwater vein A24 to be pumped. While being able to prevent land subsidence.

Examples of the present invention were conducted in early summer. A copper pipe with a fin length of 15 mm and a copper pipe with a length of 15 mm is wound around the ceiling with four finned copper pipes attached to the ceiling, and a weak wind is applied to the fins from below to let groundwater flow through the copper pipe. We tested whether the temperature in the room changed and wind was generated. The results are shown in Table 1.

After 30 minutes, a temperature drop of 4.5 degrees was seen at room temperature 29.5 degrees, see “FIG. 13”.

In the airflow test with smoke, it was confirmed that the smoke was vertically raised near the surface and stirred and scattered near the ceiling, so that it was possible to cool in the windless state. See FIG.

Comparative example

Four stainless steel pipes with fins (stainless steel fins spirally wound for 1.5m around a 20mm stainless steel pipe with low thermal conductivity) are attached to the ceiling. Water was passed through a stainless metal tube, and the temperature change in the room was tested. The results are shown in Table 2.

Even when the difference between the room temperature and the outside air temperature is the best, only a 1.2 degree temperature drop is observed, and it has been found that the thermal conductivity of the metal pipe sending the refrigerant has an important factor. See FIG.

It is also necessary to make the air conditioner cool in the same way in general housing and other facilities such as asthma due to allergies, research facilities that dislike dust soaring, and broadcasting facilities that most dislike wind noise from being picked up by microphones.
This cooling device can be easily installed and produced, and can reduce the room temperature of the cooling target in a short time.

And between the fins 4a Passing through the louver 6b installed at the upper part of the building, the cold air from the condensed water receiver is placed outside the condensed water receiver. It is the outline | summary of the air-conditioning apparatus.
In an indoor unit of a non-cooled air conditioner, air pipes that are installed diagonally on both sides of the bottom of the dew condensation water receiver are arranged at intervals of 3 mm to 10 mm with high thermal conductivity fins that match the volume of the dew condensation water receiver in the shape of a U-shaped groove. Install so that the fins stop at the top, drill one or more pairs of holes with two holes into which the refrigerant pipe can be inserted, install the refrigerant pipe into the return and return holes, A structure of a windless cooling device in which air pipes are attached to the lower left and right sides of the fins, and air is blown obliquely symmetrically toward the gaps between the fins and the refrigerant pipes so that the refrigerant pipes are not frosted from both the left and right sides.

In the present invention, the heat absorbing means 2 is provided in the upper part of the partitioned space 1a of the cooling object 1, and the heat absorbing means 2 is obliquely below the fins 4b arranged in the refrigerant pipe 3 and the lower part thereof or in the mententry surrounding the refrigerant pipe 3. A heat absorption system equipped with air pipes 6 on both sides and surrounded by refrigerant pipes 3a, fins 4a, and air pipes 6 with a U-shaped condensed water receiving means 5 is provided with a heat exhaust means 10 in addition to the space 1a. The heat absorption means 2 is provided such that fins 4b arranged in a mentmentary surrounding the refrigerant pipe 3a are bonded to each other on the flat surfaces of the refrigerant pipe 3a formed by a semi-cylindrical semi-cylinder, and the refrigerant passes through a portion where the refrigerant is turned back. In this way, the refrigerant pipe 3a with a short adhesive surface is installed so as to reciprocate near the center of the fin 4a and is converted to heat, so that the strength of the wind coming out of the air pipe 6 is controlled so that a natural descent occurs. And between fins 4a Passing through the louver 6b installed at the upper part of the building, the cold air from the condensed water receiver is placed outside the condensed water receiver. It is the outline | summary of the air-conditioning apparatus.
As shown in FIG. 10, the refrigerant pipes have the same quality and the same dimensions, and two sets of semi-cylindrical pipes are joined together, and the respective plane portions are bonded to form one cylinder. Adhered kamaboko-shaped refrigerant pipes, one for the inlet side and the other for the outlet side, allow the refrigerant to be folded back, so that the end part of the cylindrical refrigerant pipe is closed with a lid with a space inside. The structure of the endothermic device that is designed to reciprocate in the cylinder.

In order to perform airless cooling more effectively, it is possible to level the temperature of the air cooled by the refrigerant and increase the efficiency of the cooling by adopting a structure in which the refrigerant pipes are in contact with a plurality of sets of fins.
The biggest drawback of the refrigerant pipe having a structure in which the cooling is performed with the one-way refrigerant pipe is that the refrigerant temperature is unstable and there is a temperature difference between the inlet and the outlet. In order to eliminate this drawback, the temperature can be leveled by bringing the inlet and outlet into contact with each other as a U-shaped hairpin structure, and several sets of refrigerant piping having a U-shaped hairpin-like structure are used as fins. A temperature leveling effect can be achieved by contact.

As a specific device, heat absorption means is provided in the upper part of the space to be cooled, and the heat absorption means includes refrigerant pipes in contact with the fins, air pipes and U-shaped dew condensation receiving means on the diagonally lower sides thereof. In addition to the space of the heat absorption means provided with a louver slightly smaller than the U-shaped dew condensation water receiver above the fins, a heat exhaust means is provided, and the heat absorption means is a member having fins and has a plurality of fins and a refrigerant pipe Is a cooling device characterized in that a fin is reciprocated through a refrigerant pipe having an appropriate length.
The refrigerant pipe is formed in a hairpin shape, and the refrigerant pipe is reciprocated for the purpose of leveling because the temperature of the refrigerant passing through the refrigerant pipe is different between the inlet and the outlet. It was set as the structure which put the fin of high heat conductivity through the made refrigerant piping. Further, in order to level the temperature, the cold air can be leveled by bringing a plurality of sets of refrigerant pipes into contact with a common fin.

  In order to further compensate for the disadvantage that the temperature near the inlet of the refrigerant pipe and the temperature near the outlet are not the same, which is the only disadvantage of cooling the gas as a refrigerant by integrating the refrigerant pipe with the hairpin structure, the refrigerant pipe is shaped like a semi-cylindrical shape. The heat conversion can be efficiently performed in a shape in which flat portions are in close contact with each other as semicircles and fins arranged in a flat plate are skewered. By attaching a hollow cap so that the refrigerant can pass through the folded portion of the kamaboko refrigerant pipe, the inlet and outlet of the refrigerant pipe are in close contact with each other, and the temperature difference is minimized.

The material of the above air piping may be vinyl chloride resin or metal, which is easy to process, and as a single unit with a dew condensation water receiver for manufacturing, a small hole is made to fit the pitch of the fin passing through the refrigerant piping instead of the slit. By making it hit a fin or passing between fins, the heat conversion becomes a larger value. In this case, the shape of the air pipe through which air passes may be round, triangular, or polygonal. In this case, a few millimeters wide slit is opened in parallel with the air pipe, and the slit is partially closed with adhesive tape such as aluminum foil, aluminum tape, paper tape, cloth, etc. It is also possible to make holes easily by providing holes.

Also, several refrigerant pipes with fins installed near the ceiling are used as one set, and a drain pan that receives the air pipe and condensed water is set at the lower part of the refrigerant pipe to form one collective heat absorption unit. Make it possible. For this reason, providing a finned refrigerant pipe connection port, an air pipe connection port, and a drain pan connection port in the collective heat absorption unit facilitates cooling of a large building.

  The air pipe for passing air according to the present invention may be an air pipe that is attached so that air strikes the refrigerant pipe obliquely on both sides of the refrigerant pipe and the U-shaped drain pan, or that is integrally molded with the U-shape. The air pipe installed at the corner could be solved by adhering to the drain pan so that the direction of the wind did not change. The starting point from which the wind of the air pipe 6 is blown is divided into several air pipes 6 so that the positions of the starting points of the slits are dispersed in several places, thereby making it easy to achieve uniform air flow.
