In addition, to cool a refrigerant, groundwater is pumped up into a water tank installed over or under the ground, a condenser is submerged in the water tank, and cooling water heated through thermal conversion is returned using a pressure pump to an underground water vein different in stratum from an underground water vein from which the groundwater has been pumped up, thereby avoiding temperature rise in ambient air.

Description

  The present invention relates to an air conditioning method under windless conditions in a building and an apparatus 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 perform air conditioning in buildings where badminton and table tennis are performed 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. In addition, research facilities that dislike dust soaring need to be air-conditioned in the same way.

  As a cooling device that performs indoor cooling in a large facility such as a gymnasium that is generally used in general, a fan or a heat sink having a fin that contacts a metal pipe that passes gas or water as a refrigerant to increase the heat absorption area An air-cooled type or water-cooled type heat pump air conditioner is generally used to cool the room with cold air that has been controlled by the blown air and controlled by cold air cooled by heat conversion.

  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 Application Laid-Open No. 2000-28167 proposes a structure in which a venturi is provided to move air in a large building, but it does not enable cooling under no wind condition as in the present invention.

  The present invention seeks to provide a method and apparatus for enabling air conditioning in a building without wind. The term “no wind” as used herein means that no horizontal wind is generated inside the building. Furthermore, the present invention is intended to facilitate the installation work of the air conditioner.

In the present invention, the heat absorbing means 2 is provided in the upper part of the partitioned space 1a of the air-conditioning target 1, and the heat absorbing means 2 is provided with the refrigerant pipe 3 and the condensed water receiving means 5 in the lower part thereof, and the heat exhausting means 10 is provided in addition to the space 1a. Thus, the air conditioning method is performed in a windless state in a building in which cooling is performed by a natural descent of the cool air in the upper part of the space 1a in which the heat absorbing means 2 is provided.
As a specific device, heat absorption means 2 is provided in the upper part of the partitioned space 1a of the air-conditioning target 1, and the heat absorption means 2 includes a refrigerant pipe 3 and a condensed water receiving means 5 in the lower part thereof. Means 10 is provided, and the heat absorbing means 2 is an air conditioner characterized in that the outer periphery of the refrigerant pipe 3 is covered with a member having fins 4a.

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 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 uses the action of descending naturally. It was decided to perform cooling.
That is, the heat absorption means 2 is provided in the upper part of the partitioned space 1a of the air-conditioning target 1, the heat absorption means 2 includes 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. A windless air-conditioning method in a windless state in a building in which cooling is performed by a natural descent of the cool air in the upper part of the space 1a in which the heat absorbing means 2 is provided, and a device used therefor.

  Although cooling by natural subsidence of cold air is performed, in order to perform greater heat conversion, the air pipe 6 is provided in any of all directions around the finned refrigerant pipe 4 and the finned refrigerant pipe 4 extending straight or curved A slit 6a and countless holes 6b are formed in accordance with the direction in which the wind hits the upper part of the air pipe 6 installed in parallel with the finned refrigerant pipe 4 or the finned refrigerant pipe 4 from either the lower side, the side or the upper side. A small amount of wind is blown toward the fins 4a so that the cold air is peeled off from the finned refrigerant pipe 4 through the holes 6b that are opened and attached in the direction in which the wind hits the fins 4a. At this time, air is blown by controlling the strength applied to the fins 4a so as not to affect the windless state from the floor to a height where the windless state is required.

  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 larger value. In this case, the shape of the air pipe 6 through which air passes may be round, triangular or polygonal. In this case, in order to manufacture the hole 6b, a slit 6a having a width of several millimeters is opened 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, cloth, The hole 6b can be easily made by providing a hole having a required size.

  In addition, several sets of finned refrigerant pipes 4 installed near the ceiling are set as one set, and an air pipe 6 and a drain pan 5a for receiving condensed water are set below the finned refrigerant pipes 4 and stored in a frame 7a. 7 and a number of collective endothermic units 7 can be connected. For this reason, providing the finned refrigerant pipe connection port 7b, the air pipe connection port 7c, and the drain pan connection port 7d in the collective heat absorption unit 7 simplifies the cooling of a large building. Further, instead of the finned refrigerant pipe 4, a high heat conductivity refrigerant pipe 3 sandwiched between high heat conductivity metal flat plates is arranged as a metal flat plate heat absorbing material 8c so that the inlet and outlet of the refrigerant can be connected, and according to the size. The number of sheets can be connected to form the heat absorbing means 2. At this time, if it is installed horizontally, the condensed water may fall on the floor. Therefore, in order to prevent the condensed water from falling, the metal flat plate heat-absorbing material 8c is inclined so that the condensed water flows along the metal surface. The drain pan 5a is provided at the lowermost part where the condensed water of the metal flat plate heat absorbing material 8c gathers. In this case, the air pipe 6 may be attached to the ceiling surface or the bottom surface of the metal flat plate heat-absorbing material 8c, and the metal flat plate of the metal flat plate heat-absorbing material 8c is made into a corrugated plate, thereby increasing the heat absorption area and improving the cooling efficiency. At this time, the metal flat plate heat absorbing material 8c is used as the flat plate heat absorbing device 8, and the air pipe 6 and the drain pan 5a are incorporated into a unit so that the necessary number can be connected by a simple construction. Construction can be done without. This unitization makes it possible to cool a large building by installing several sets of air conditioners by the capacity of the compressor 10a in one building. At this time, the refrigerant sandwiched between the metal flat plate heat absorbing materials 8c By injecting the high thermal conductivity filler 8b into the gap other than the pipe 3, more efficient heat conversion can be performed.

When this apparatus is used to cool the room with a refrigerant, the cooled refrigerant exchanges heat with the warm air in the room, and then returns to the compressor 10a to cool the refrigerant because the refrigerant compressed by the compressor 10a is at a high temperature. The condenser 10b, the compressor 10a and the blower fan are usually integrated with the outdoor unit, and the refrigerant having a high temperature is cooled by applying air to the condenser 10b with a fan, but separated from the outdoor unit. Then, the fan is removed, the compressor 10a and the condenser 10b are separated, ground water or ground water is stored in the water tank 20 in which the condenser 10b is installed underground or above the ground, and the water is accumulated in the water stored in the water tank 20. The condenser 10b is submerged. At this time, since it is necessary to cool a plurality of condensers 10b in a large-scale facility, these condensers 10b are submerged in a water tank 20 installed on the ground or on the ground at once to efficiently cool the refrigerant that has become hot. Can be cooled. In addition, it can prevent the surrounding air from warming with the high-temperature wind generated by air-cooling, and warm water can be used for hot water pools, showers, etc. Boilers such as heavy oil are used to generate water, but cost can be reduced by using water after heat conversion with high water temperature.
Although the method of cooling the condenser 10b in the water tank 20 can also be seen in Japanese Patent Laid-Open No. 8-296266, it is impossible to cool a plurality of condensers 10b in the water tank 20 by this method.

  In this case, aluminum heat absorption auxiliary material is usually attached to the copper refrigerant pipe 3, but since it will be immersed in water for a long time, the submerged part is plated with a material with high thermal conductivity to prevent deterioration of gold or silver. Alternatively, it is better to take measures to prevent deterioration due to metal oxidation and decrease in thermal conductivity by applying heat-resistant and oxidation-resistant substances with high thermal conductivity.

  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 a general indoor unit in which a heat absorber and a fan are set, and is cooled by wind. The compressor room condenser 10e is cooled in the same water tank 20 as the other condensers 10b. Do.

  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 is 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 6 for passing air of the present invention was installed between the finned refrigerant pipe 4 and the drain pan 5a and could be solved by attaching the air pipe fixing tool 6c to the air pipe 6 so that the direction of the wind does not change. The starting point from which the wind of the air pipe 6 blows is divided into several air pipes 6 so that the positions of the starting points of the slits 6a are dispersed in several places, so that it is easy to make the air volume uniform.

  The compressor 10a, the condenser 10b, and the fan of the air conditioner are removed, and the compressor 10a is accommodated 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 air conditioning in a building for playing badminton and table tennis 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-conditioned without wind.

  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 air conditioning 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 absorption means 2 of the present invention is separated from the compressor 10a and the condenser 10b, the air conditioning 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 air conditioner in the compressor chamber 30 where 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, etc. 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 2 in the upper part of the partitioned space 1a of the air-conditioning target 1 in the windless state, and the heat absorbing means 2 includes the refrigerant pipe 3 and the condensed water receiving means 5 in the lower part thereof. The exhaust heat means 10 is provided in a place other than the space 1a, and the space 1b that does not like badminton is cooled by the natural descent of the cool air above the space 1a in which the heat absorption means 2 is provided. . As a result, the air conditioner can be air-conditioned under no wind conditions.

  Therefore, the air conditioner includes a refrigerant pipe 3 and a drain pan 5a as a condensed water receiving means 5 below the refrigerant pipe 3 so that the heat absorbing means 2 of the partitioned space 1a of the air conditioning target 1 can be seen in FIG. In addition to this space 1a, exhaust heat means 10 is provided as a condenser 10b and a compressor 10a. As shown in FIG. 3, the heat absorbing means 2 is characterized in that the outer periphery of the refrigerant pipe 3 through which the refrigerant passes is covered with a member having fins 4a.

In the heat absorbing 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 is provided with a plurality of collective heat absorption units 7 including finned refrigerant pipes 4 and air pipes 6 above the drain pan 5a, and finned refrigerant pipe connection ports 7b and air pipe connection ports 7c with other collective heat absorption units 7. And the structure covered with the frame 7a which has the drain pan connection port 7d is good.
The heat-absorbing means 2 has a necessary number of units only to cover the construction area of the air conditioner by providing a drain pan 5a below the flat metal heat-absorbing material 8c in which the refrigerant pipe 3 is laid in a flat metal plate (or a metal frame) having high thermal conductivity. Use it. Further, the metal flat plate heat absorbing material 8c includes an air conditioner provided with a refrigerant pipe connection port 7e and a drain pan connection port 7d so that metal flat plates (which may be metal frames) can be mounted side by side or attached at an angle. You can also A set of several finned refrigerant pipes 4 installed in the vicinity of the ceiling, and a set of heat sink units 7 are set in a frame 7a by placing an air pipe 6 and a drain pan 5a for receiving condensed water at the lower part of the finned refrigerant pipe 4. In order to make it possible to connect a number of collective endothermic units 7, it is possible to easily carry out cooling of a large building by providing the finned refrigerant pipe connection port 7 b, the air pipe connection port 7 c and the drain pan connection port 7 d in the collective heat absorption unit 7. Also, instead of the finned refrigerant pipe 4, a high thermal conductivity refrigerant pipe 3 sandwiched between high thermal conductivity metal flat plates is arranged as a metal flat plate heat absorbing material 8 c so that the inlet and outlet of the refrigerant can be connected to meet the size. The heat absorption means 2 is formed by connecting the numbers. At this time, if it is installed horizontally, the condensed water may fall on the floor. Therefore, in order to prevent the condensed water from falling, the attachment of the metal flat plate heat absorbing material 8c is inclined 8a so that the condensed water flows along the metal surface. The drain pan 5a is provided at the lowermost part where the condensed water of the metal flat plate heat absorbing material 8c gathers. In the flat metal heat absorbing material 8c, an air pipe 6 having an opening facing the flat metal heat absorbing material 8c is provided on the ceiling surface or the bottom surface of the flat metal heat absorbing material 8c. The collective endothermic unit 7, the metal plate endothermic material 8 c, and the plate endothermic device 8 may be provided with a flow rate control means for air blown from the opening.

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.
