Description

  The present invention relates to a water circulation type environmental control system that circulates water as a heat medium to cool or heat an internal space of a predetermined structure.

  Conventional environmental control systems usually circulate a coolant such as water between a condenser and an evaporator by a pump. During cooling, the liquid refrigerant in the evaporator removes the heat in the air to remove the cold air. Then, the cold air is sent indoors by a blower, and the evaporated refrigerant (refrigerant vapor) releases heat to the outside air by a condenser and returns to a liquefied refrigerant. On the other hand, during heating, heat is released into the air by liquefying the refrigerant vapor in the condenser to create warm air, the warm air is sent into the room by a blower, and the liquefied refrigerant is heated by the outside air in the evaporator. A cycle of returning to the refrigerant vapor is performed.

  In such an environmental control system, it is necessary to operate the pump with a motor or the like for the circulation of the refrigerant, and it is necessary to supply cold air or warm air to the room with a blower. there were.

  On the other hand, in recent years, an environmental control system using geothermal heat as natural energy has been proposed (see Patent Document 1). In this environmental control system, a heat exchanging pipe is vertically embedded in the ground, and an upper end opening of the heat exchanging pipe is provided in a heat accumulating chamber on the floor of the building, and a ventilation pipe standing from the heat accumulating chamber to the ceiling of the building. Is opened under the ceiling, and an electric fan is provided in the ventilation pipe. When cooling in the summer, the air is sucked from the heat storage chamber with an electric fan and sent from the bottom of the ceiling to the room, and the vacuum in the heat exchange pipe that has been cooled in the ground is sucked up by the suction. To replenish. When heating in winter, the indoor air sucked from under the ceiling is sent to the heat storage room with an electric fan, and the air in the heat storage room is heated by passing through the heat exchange pipe heated in the ground by the increased pressure. It is sent indoors.

  Or the environmental control system using the geothermal and solar heat as natural energy is also proposed (refer patent document 2). This environmental control system embeds a heat exchange pipe horizontally in the ground, opens one end of the heat exchange pipe to the outside air, and connects the other end to a ventilation pipe into the building via a switching valve. A solar wall heated by sunlight is provided outside the building, the solar wall is connected to a ventilation pipe into the building via the switching valve, and an electric fan is provided in the ventilation pipe. During cooling in summer, the heat exchange pipe cooled in the ground is connected to the ventilation pipe by a switching valve, and the air in the heat exchange pipe is sent indoors by an electric fan. When heating in winter, the solar wall is connected to the ventilation pipe by a switching valve, and the warm air in the solar wall is sent indoors by an electric fan.

  Although these environmental control systems do not require the pump to be operated with a motor or the like to circulate the refrigerant, it is necessary to supply cold air or warm air to the room with an electric fan, so power supply is indispensable. It was not in line with the recent demand for energy conservation.

  On the other hand, other environmental control systems using geothermal heat and solar heat as natural energy have been proposed (see Patent Document 3). This environmental control system embeds a heat exchange pipe in the ground, opens one end of the heat exchange pipe to the outside air, leads the other end into the building, and inclines a duct heated by sunlight on the roof of the building. One end of this duct is opened to the outside air and the other end is led into the building. During cooling in the summer, the air inside the duct on the roof is released to the outside air, and the air inside the building is sucked into the duct, which reduces the heat that is cooled in the ground. Cold air in the exchange pipe is sucked out and sent to the building.

  In this environmental control system, the cold air in the heat exchange pipes cooled in the ground is sucked and supplied to the building by decompressing the inside of the building with a duct. It was easy to be affected by the pressure change of the building and could not cool the building sufficiently.

  Under these circumstances, the present inventors embed a ground channel that is embedded along an inclined surface of the ground and is cooled by the ground temperature, an outside air inlet connected to the upper end of the underground channel, An air discharge port is provided in the internal space and connected to the lower end of the underground flow path.Air in the underground flow path is cooled by the underground flow path, and the air discharge is caused to flow down in the underground flow path. The environmental control system was invented by discharging from the outlet to the internal space of the structure and allowing outside air to be taken into the underground channel from the outside air intake as the air in the underground channel descends.

This environmental control system does not require any drive device such as a pump or a motor, and can be effectively used in mountainous areas where it is difficult to supply power.

The efficiency of cooling or warming can be improved, and cool air or warm air can be fed from an exhaust port provided in the internal space of the structure.

  FIG. 1 is a schematic diagram of a water circulation environmental control system according to the first embodiment. This water circulation type environmental control system includes a water guide pipe 11 that constitutes a circulation flow path for circulating water, and a water feeder 12 that feeds water from a distal end 11b of the water guide pipe 11 to a base end 11a.

  In particular, the water conduit 11 has a base end 11a and a distal end 11b arranged at a predetermined height, and a folded portion 11c where the water conduit 11 is folded back is lower than the first altitude where the base end 11a and the distal end 11b are disposed. By providing the base end 11a at a position higher than the tip end 11b, water can be circulated along the water conduit 11 using the differential pressure between the base end 11a and the tip end 11b. . The water that has reached the tip 11b is fed to the base end 11a by the water feeder 12. The water sent through the water conduit 11 is preferably relatively clean water such as tap water, but may be anything as long as it is clean.

  The water conduit 11 is buried in the ground. The portion buried in the ground is a cold storage unit 11d, which cools the water inside the water conduit 11 by heat exchange with geothermal heat. In addition, it is desirable to use a metal pipe with high thermal conductivity for the water conduit 11 of the cold storage unit 11d. The cold storage unit 11d is not only configured by being buried in the ground, but also uses a low temperature environment such as a pond, river, lake, swamp, sea, ice room, snow storage room, water tank, etc. be able to. In this embodiment, the water conduit 11 is embedded at a depth of about 2 m underground. It is desirable to embed the water conduit 11 as deeply as possible.

  Further, the water conduit 11 is provided with a cooling part 11e for cooling with water cooled by the cold storage part 11d on the downstream side of the cold storage part 11d, and the cooling part 11e is provided in the internal space of the predetermined structure 13. The internal space is cooled by the cooling unit 11e. The structure 13 may be a general house, a pig farm, a chicken farm, a building such as a factory or a high-rise building, or a constant temperature facility such as a plastic house. In this embodiment, cultivation facilities, such as a greenhouse, are assumed. In the internal space of the structure 13, the cooling unit 11e may be arranged in an appropriate shape so as to increase the cooling efficiency.

  Note that it is desirable to use a metal pipe having high thermal conductivity for the water conduit 11 of the cooling unit 11e. In addition, between the cooling unit 11e and the cold storage unit 11d, for example, a plastic pipe having a lower thermal conductivity than metal is interposed, and the surroundings are further insulated to guide the cooling unit 11e and the cold storage unit 11d. It is desirable to suppress a decrease in thermal efficiency due to heat conduction through the water pipe 11 itself.

  As shown in FIG. 2, the water feeder 12 is a pump including a water vapor generating unit 12-1 that generates water vapor by solar heat and a piston 12-2a that is driven forward and backward by the water vapor generated by the water vapor generating unit 12-1. It consists of part 12-2.

  The water vapor generation unit 12-1 is provided with a water storage tank 12-1a to which water that has reached the tip 11b of the water conduit 11 is supplied, and the water in the water storage tank 12-1a is provided above the water storage tank 12-1a. It has an evaporation chamber 12-1b that generates water vapor by heating with solar heat. A steam supply pipe 12-1c for supplying steam to the pump unit 12-2 is connected to the evaporation chamber 12-1b in communication.

  The pump unit 12-2 is supplied from the water vapor generating unit 12-1 via the first cylinder chamber 12-2b to which water reaching the tip 11b of the water conduit 11 is supplied and the water vapor supply tube 12-1c. The second cylinder chamber 12-2c and the piston 12-2a slidably provided between the first cylinder chamber 12-2b and the second cylinder chamber 12-2c are provided. 12-2b is provided with a water supply pipe 12-2d that feeds water from the first cylinder chamber 12-2b to the base end 11a of the water guide pipe 11 by being pushed by the piston 12-2a. Further, the second cylinder chamber 12-2c is provided with a relief valve 12-2e that discharges water vapor in the second cylinder chamber 12-2c to the outside at a predetermined timing.

  In the water feeder 12, the inside of the second cylinder chamber 12-2c is pressurized by the steam generated by the steam generating section 12-1, and the piston 12-2a is made to pressurize the first cylinder chamber by the pressurization in the second cylinder chamber 12-2c. The water in the first cylinder chamber 12-2b is fed to the base end 11a of the water guide pipe 11 through the water supply pipe 12-2d by being pushed to the 12-2b side.

  Then, by opening the relief valve 12-2e at a predetermined timing, the second cylinder chamber 12-2c is depressurized to retract the piston 12-2a, and then the relief valve 12-2e is closed. In this embodiment, the opening / closing control of the relief valve 12-2e is performed by a timer unit (not shown) provided in the relief valve 12-2e, and is opened for a predetermined time at predetermined time intervals. The electric power required for the operation of the timer unit can be provided by the photovoltaic power generation system.

  For example, as shown in FIG. 3, the water feeder 12 is provided with a suction portion 12-3 above the tip 11b of the water conduit 11, and the tip of the water conduit 11 is formed by the suction portion 12-3. The water 11b may be sucked and supplied to the base end 11a of the water guide pipe 11 through the water supply pipe 12-4.

  The suction unit 12-3 heats the water in the water storage tank 12-3a, the suction pipe 12-3b that sucks water from the tip 11b of the water conduit 11 into the water storage tank 12-3a, and the water in the water storage tank 12-3a. A relief valve 12-3c that discharges the generated water vapor and an open / close valve 12-3d that controls open / close of the communication state of the water supply pipe 12-4 are provided. In FIG. 3, 12-3e is a solar light collecting device for generating water vapor by heating water in the water storage tank 12-3a with solar heat.

  In this suction section 12-3, the relief valve 12-3c and the on-off valve 12-3d are closed, respectively, and water in the water storage tank 12-3a is heated by solar heat to generate water vapor, and the water in the water storage tank 12-3a Is in a high pressure state.

  Next, the suction unit 12-3 opens the relief valve 12-3c, discharges the water vapor in the water storage tank 12-3a from the relief valve 12-3c, then closes the relief valve 12-3c, and the water storage tank 12 The water storage tank 12-3a is depressurized by applying water to the -3a or cooling it with cold air.

  By depressurizing the inside of the water storage tank 12-3a, water is sucked into the water storage tank 12-3a from the tip 11b of the water conduit 11 through the suction pipe 12-3b, and then the on-off valve 12-3d is opened. Thus, water is supplied from the water storage tank 12-3a to the proximal end 11a of the water guide pipe 11 through the water supply pipe 12-4.

  The water feeder 12 further comprises a windmill, and drives the appropriate motor with the rotational force of the windmill rotating by receiving wind to feed water from the tip 11b of the water conduit 11 to the base end 11a, Alternatively, as a water wheel that rotates by receiving wind, the water wheel may be rotated to supply water from the distal end 11b of the water guide pipe 11 to the base end 11a.

  Alternatively, the water feeder 12 drives the appropriate water supply pump with the power generated by the solar power generation system using the solar battery panel or the wind power generation system, thereby supplying water from the distal end 11b of the water conduit 11 to the proximal end 11a. You may send them.

  By providing not only one but also a plurality of water feeders 12 in parallel, water can be continuously supplied from the distal end 11b of the water conduit 11 to the proximal end 11a.

  Thus, in the environmental control system of the present embodiment, water can be circulated along the water conduit 11 by the water conduit 11 and the water feeder 12, and the water conduit 11 is provided with the cold storage unit 11d and the cooling unit 11e. By providing the cooling unit 11e in the internal space of the predetermined structure 13, the internal space can be cooled.

  In particular, this environmental control system circulates water, which is a heat medium, using the differential pressure between the proximal end 11a and the distal end 11b of the water conduit 11, and cools the water using geothermal heat lower than the air temperature. Since the cooling means can be driven only by natural energy, it is possible to provide a very energy saving environment control system.

  In addition, in the cool storage unit 11d, the specific gravity of the water is increased by cooling the water in the water conduit 11, and a sedimentation action can be generated in the water itself, so that a relatively large flow velocity is obtained in the water conduit 11. be able to.

  Furthermore, by providing the cooling part 11e in the folded part 11c, instead of cooling the internal space of the structure 13 in the cooling part 11e, the specific gravity is reduced in the heated water, and the water itself can be raised. Therefore, a relatively large flow rate can be obtained in the water conduit 11.

  In such an environmental control system, as shown in FIG. 1, the cold storage part 11d or the water conduit 11 downstream of the cold storage part 11d has one end as an intake port 14a and the other end as an exhaust port 14b. When the ventilation pipe 14 through which air is passed is inserted or juxtaposed, and the exhaust port 14b is provided in the internal space of the structure 13, the cold storage section 11d or the water guide pipe 11 on the downstream side of the cold storage section 11d The air cooled in step 1 can be used as cold air to discharge the exhaust port 14b into the internal space of the structure 13, thereby improving the cooling efficiency of the internal space. In particular, it is desirable that the exhaust port 14b is opened obliquely upward as shown in FIG. 1 rather than being opened vertically upward so that the cool air can be released without bending the vent pipe 14 as much as possible.

  In the present embodiment, a plurality of exhaust ports 14b are provided along the longitudinal direction of the vent pipe 14.

  On the other hand, the intake port 14a is provided with a funnel-shaped air collecting hood 14c, and by providing air collecting means that always directs the air collecting hood 14c toward the windward side, the air flow rate in the air pipe 14 is increased. The cooling efficiency of the internal space of the structure 13 is further improved.

  In addition, in the case of the environmental control system in which the ventilation pipe 14 is provided in this way, the ventilation pipe 11 is provided on the inclined ground and the water guiding pipe 11 and the ventilation pipe 14 are provided along the inclined surface of the inclined ground. The specific gravity of the air cooled by the water storage pipe 11 downstream of the cold storage section 11d or the cold storage section 11d is increased, thereby causing a subsidence flow along the ventilation pipe 14 inclined downward in the air itself. Therefore, it is possible to prevent the air from being retained in the vent pipe 14 and to smoothly feed the cold air.

  In FIG. 1, reference numeral 16 denotes an exhaust port of the structure 13, and a heating plate 17 is attached to the exhaust port 16 to further heat the exhausted gas, thereby generating a stronger rising airflow, thereby improving the disposal efficiency. Thus, the efficiency of drawing cool air from the exhaust port 14b and the air diffuser 15 can be improved.

  In this embodiment, the water conduit 11 on the downstream side of the cooling unit 11e is buried in the ground again, but it is not always necessary to bury it, and the tip 11b is adjacent to the base end 1a by being disposed along the ground. You may let them. Here, the water conduit 11 is protected by burying the water conduit 11 on the downstream side of the cooling portion 11e in the groove dug to form the cold storage portion 11d. Further, the water conduit 11 on the downstream side of the cooling unit 11e is prevented from becoming an obstacle on the ground.

  In the environmental control system of this embodiment, as shown in FIG. 1, the cooling portion 11e of the water conduit 11 is disposed in the internal space of the structure 13, and cold air is supplied from the vent tube 14. Although the internal space is cooled, as shown in FIG. 4, the water conduit 11 is not arranged in the internal space of the structure 13, and the structure 13 is formed from the ventilation pipe 14 inserted or juxtaposed with the water conduit 11. It is also possible to just send cold air to the interior space.

  In the embodiment of FIG. 4, a diffuser pipe 15 provided with a plurality of openings 15a is attached to the exhaust port 14b so that the cool air supplied from the vent pipe 14 can be efficiently discharged.

  FIG. 5 is a schematic diagram of a water circulation environmental control system according to the second embodiment. This water circulation type environmental control system also includes a water guide pipe 21 that constitutes a circulation channel for circulating water, and a water feeder 22 that feeds water from the distal end 21b of the water guide pipe 21 to the base end 21a.

  In particular, the water conduit 21 has a proximal end 21a and a distal end 21b arranged at a predetermined height, and a folded portion 21c where the water conduit 21 is folded back is lower than the first altitude where the proximal end 21a and the distal end 21b are disposed. By providing the base end 21a at a higher position than the front end 21b, water can be circulated along the water conduit 21 using the differential pressure between the base end 21a and the front end 21b. . The water that has reached the distal end 21b is fed to the proximal end 21a by the water feeder 22.

  The conduit pipe 21 is buried in the ground. The portion buried in the ground is a heat storage portion 21d, which heats the water inside the water conduit 21 by heat exchange with the geothermal heat. In addition, it is desirable to use a metal pipe with high thermal conductivity for the water conduit 21 of the cold storage unit 21d. The heat storage unit 21d is not only configured to be buried in the ground, but also has a temperature higher than the temperature of a pond, river, lake, swamp, sea, hot spring, high-temperature waste heat body, high-temperature waste heat chamber, water tank, etc. High temperature environment can be used. In this embodiment, the water conduit 21 is embedded at a depth of about 2 m or less underground where the temperature is about 10 ° C. It is desirable to embed the water conduit 21 as deeply as possible.

  Further, the water guide pipe 21 is provided with a heating part 21e for heating with water heated by the heat storage part 21d on the downstream side of the heat storage part 21d. The heating part 21e is a predetermined structure 23. The internal space is heated by the heating unit 21e. The structure 23 may be a general house, a pig farm, a chicken farm, a building such as a factory or a high-rise building, a constant temperature facility such as a plastic house, a small doghouse, or the like. Also in this embodiment, cultivation facilities, such as a greenhouse, are assumed. In the internal space of the structure 23, the heating part 21e may be arranged in an appropriate shape so as to increase the cooling efficiency.

  Note that it is desirable to use a metal pipe having high thermal conductivity for the water conduit 21 of the heating unit 21e. In addition, a plastic pipe or the like having a lower thermal conductivity than metal is interposed between the heating unit 21e and the heat storage unit 21d, and the water conduit 21 itself is interposed between the heating unit 21e and the heat storage unit 21d. It is desirable to suppress the decrease in thermal efficiency due to the generated heat conduction.

  In this embodiment, the water feeder 22 is constituted by a windmill, and drives water by the rotational force of the windmill that rotates by receiving wind to feed water from the distal end 21b of the water conduit 21 to the proximal end 21a. ing. The water feeder 22 may be appropriately configured as described above.

  Thus, in the environmental control system of this embodiment, water can be circulated along the water conduit 21 by the water conduit 21 and the water feeder 22, and the water conduit 21 is provided with the heat storage portion 21d and the heating portion 21e. Thus, by providing the heating portion 21e in the internal space of the predetermined structure 23, the internal space can be heated.

  In particular, this environmental control system circulates water, which is a heat medium, using the differential pressure between the proximal end 21a and the distal end 21b of the conduit 21 and cools the water using geothermal heat lower than the air temperature. Since the cooling means can be driven only by natural energy, it is possible to provide a very energy saving environment control system.

  In the present embodiment, by providing the environmental control system on an inclined land, a relatively long water conduit 21 of about 100 m can be easily embedded in the basement, and the length of the heat storage portion 21d is made as long as possible to improve the thermal efficiency. While improving, it can suppress that installation cost rises.

  As another embodiment, as shown in FIG. 6, the water conduit 21 and the water feeder 22 circulate water to generate high-temperature water by geothermal heat, and one end of the water conduit 21 is connected to the intake port. 24a, with the other end as an exhaust port 24b, a ventilation pipe 24 through which air is passed, and the air passing through the ventilation pipe 24 is heated to provide a higher position than the water conduit 21 You may make it discharge | release the warm air warmed with the water conduit 21 to the internal space of the thing 23 '. In FIG. 6, reference numeral 25 denotes an air diffuser connected to the exhaust port 24b, and includes a plurality of discharge ports 25a. In FIG. 6, reference numeral 24c denotes a wind collecting hood provided in the intake port 24a and opened in a funnel shape.

  A buffer portion 24d is provided in the middle of the ventilation pipe 24 to prevent the heated air from being blown into the internal space of the structure 23 'at a high speed.

  Further, the water guide pipe 21 is provided with a deep buried portion 21f buried deeper so that water can be stably heated. That is, since the temperature change is relatively large in the ground near the ground surface, it is made difficult to be affected by the temperature change by being buried deeply.

  As described above, in the environmental control system of the present invention, water is circulated using differential pressure, so it can be installed not only on sloped land but also on flat ground, parking lots, manhole interiors, roads, vacant land, Water can be cooled by using a low-temperature ground temperature of 2 m or less such as adjacent farmland or fallow paddy field.

  This environmental control system can also cool the building by taking in outside air through the ventilation pipe 14, so natural air such as fresh forest air can be taken into the room.

  Hereinafter, specific embodiments of the present invention will be briefly described with reference to the drawings.

  FIG. 7 shows a case where a water circulation type environmental control system is provided in the kennel. A part of the water conduit 31 constituting the circulation flow path for circulating water is buried in the basement of the kennel and guided by the water supply 32. Water is fed from the tip 32b of the water pipe 31 to the base end 32a to cause water circulation. Thereby, the dog house can be cooled in the summer, and the dog house can be heated in the winter.

  In FIG. 7, reference numeral 34 denotes a vent pipe 34 provided in parallel with the water conduit 31. The air sucked from the air inlet 34 a of the vent pipe 34 is cooled or heated by the water conduit 31, and exhausted in the doghouse. Cold air or warm air can be sent out from the mouth 34b. 34c is a wind collecting hood provided in the intake port 34a and opened in a funnel shape. 34d is a sprayer for spraying a volatile insect repellent to the air passing through the ventilation pipe 34.
