[0002] The constant temperature air conditioning dehumidifier processes the air through the evaporator and condenser to achieve the purpose of temperature control and dehumidification. When the indoor humid air passes through the surface of the evaporator, because the evaporator temperature is lower than the dew point temperature of the humid air, the water vapor in the air condenses and separates, accumulates in the water receiving tray, and is discharged through the water pipe, and the moisture content of the air decreases.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a constant temperature air conditioning dehumidifier for a swimming pool with constant temperature of swimming pool water. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1 - Fig.14 As shown, the present invention provides: a constant temperature air conditioning dehumidifier for a swimming pool hall with constant temperature of swimming pool water, comprising a dehumidification mechanism 10 and a return air duct group 20, the dehumidification mechanism 10 comprising an evaporator 11 fixed in a casing of the constant temperature air conditioning dehumidifier and a water receiving tray 12 fixed at the bottom of the evaporator 11, one side of the water receiving tray 12 is connected through a lower drain pipe 13 for discharging condensed water, the return air duct group 20 comprises a dehumidification pipe group 21 for dehumidification, the dehumidification pipe group 21 is hoisted indoors, the dehumidification pipe group 21 is made of stainless steel sheet, the dehumidification pipe group 21 made of stainless steel sheet is not easy to rust, the cost is low, and the heat transfer effect is good, the dehumidification pipe group 21 is exposed in the indoor swimming pool, and the humid air is condensed and dried through the contact between the inner wall and the outer wall of the pipe and the humid air, the humidity of the air entering the evaporator 11 is reduced, and the initial dehumidification is performed; The dehumidification pipe group 21 is connected to the machine room connection pipe group 22, which is used to connect the dehumidification pipe group 21 and the machine room. The machine room connection pipe group 22 is provided with multiple sections and is placed outside the indoor swimming pool. In order to prevent the humid air heat from being lost in large quantities when passing through the machine room connection pipe group 22, a layer of insulation is wrapped on the surface of the machine room connection pipe group 22 to prevent the humid air from being reduced and passing through the evaporator 11, causing the evaporator 11 to frost on the surface; The dehumidification pipe group 21 includes an air supply chamber 202 and a return air chamber 205 which are interconnected. Both ends of the air supply chamber 202 and the return air chamber 205 are open structures. The return air conditioning pipe group 30 adjusts the air temperature of the air supply chamber 202 and the return air chamber 205, thereby adjusting the temperature of the surface of the entire dehumidification pipe group 21. When the surface temperature of the dehumidification pipe group 21 is lower than the temperature of the humid air, the water vapor in the humid air is condensed and separated. A return air conditioning pipe group 30 is fixedly installed on one side of the evaporator 11 (the side close to the air supply pipe), and an air outlet 221 of the machine room connecting pipe group 22 is placed on the other side of the evaporator 11 (the side away from the air supply pipe), and at the same time, the air outlet 221 is placed above the water receiving tray 12, and the condensed water in the return air pipe group 20 drips into the water receiving tray 12 through the air outlet 221, and the return air conditioning pipe group 30 is connected with the air supply cavity 202 and the return air cavity 205, and the return air conditioning pipe group 30 is used for air conditioning in the air supply cavity 202 and the return air cavity 205, and the return air conditioning pipe group 30 absorbs cold air and delivers cold air to the air supply cavity 202, and the air supply cavity 202 cools down the dehumidification pipe group 21 when flowing through the return air cavity 205, and the surface temperature of the dehumidification pipe group 21 is lower than the dew point temperature of the humid air, and at this time, water droplets condense on the inner wall and surface of the dehumidification pipe group 21 to complete the initial dehumidification; Finally, the air flows back to the machine room connecting pipe group 22 through the cooperation of the return air conditioning pipe group 30 for mixing, and then passes through the evaporator 11 for secondary dehumidification; The dehumidification pipe group 21 is in contact with the indoor humid air to increase the condensation contact area, and the humid air is first dehumidified by the dehumidification pipe group 21, and then dehumidified twice by the evaporator 11, so that the air humidity in the swimming pool can be quickly reduced; When the dehumidification pipe group 21 is performing dehumidification, a large amount of water droplets condensed on the surface drip into the condensation water collection component 40 fixed below the dehumidification pipe group 21 under the action of gravity, and then the condensation water collected by the dehumidification pipe group 21 during the dehumidification process can be discharged centrally through the condensation water collection component 40.

[0020] like Figure 7 - Fig.12 As shown, the dehumidification pipe group 21 includes an upper air inlet pipe 211 and a return air pipe 212, the air supply chamber 202 is opened on the upper air inlet pipe 211, and the return air chamber 205 is opened on the return air pipe 212. The cross-sections of the upper air inlet pipe 211 and the return air pipe 212 are arc-shaped structures, and the upper air inlet pipe 211 and the return air pipe 212 can be disassembled and assembled to facilitate the formation of the air supply chamber 202 in the upper air inlet pipe 211 and the return air chamber 205 in the return air pipe 212. The upper air inlet pipe 211 and the return air pipe 212 are spliced ​​to form a circular pipe. The circular pipe has a large dehumidification area and is conducive to condensation. Water gathers downward along the arc surface and drips into the condensate water collection assembly 40. A pipe cap 217 is detachably installed between one end of the upper air inlet pipe 211 and the lower air return pipe 212. The air supply chamber 202 between the head and tail of the multiple sections of the upper air inlet pipe 211 is connected, and the return air chamber 205 of the multiple sections of the return air pipe 212 is connected between the head and tail. Therefore, it can be assembled according to swimming pools of different sizes. The upper air inlet pipe 211 at one end is connected to the return air pipe 212 through the pipe cap 217. At this time, the airflow passes through the return of the pipe cap 217, so that the airflow in the air supply chamber 202 is transported to the return air chamber 205. By connecting the multiple upper connecting pieces 203 fixed on both sides of the upper air inlet pipe 211 and the multiple fixing plates 206 fixed on both sides of the return air pipe 212, the upper air inlet pipe 211 and the return air pipe 212 can be assembled into a circular pipe; In order to disperse the humid air and increase the contact area between the humid air and the dehumidification pipe group 21, a plurality of upper air inlets 201 are provided on the upper air inlet pipe 211, and a plurality of lower air inlets 204 are provided on the return air pipe 212. The lower air inlet 204 is provided at the lowest point of the return air pipe 212. The lower air inlet 204 passes through the return air pipe 212 and is not connected to the return air chamber 205. The upper air inlet 201 passes through the upper air inlet pipe 211 and is not connected to the air supply chamber 202. like Fig. 9 As shown, when the equipment is running as a whole, a negative pressure is formed inside the dehumidification tube group 21, and humid air is sucked into the pipe of the dehumidification tube group 21 through the upper air inlet 201 and the lower air inlet 204. During this process, the high-temperature humid air is dispersed, and a part of the humid air flows upward through the upper air inlet 201 and flows into the tube, and the other part of the humid air flows downward through the lower air inlet 204 and flows into the tube. Then, through the humid air diverted up and down, the contact area between the humid air and the outer surface of the dehumidification tube group 21 can be maximized, thereby ultimately improving the dehumidification effect of the dehumidification tube group 21.

[0021] like Figure 7 - Fig.12 As shown, a plurality of upper fin tubes 215 are distributed in an annular manner on the inner wall of the upper air inlet pipe 211, and a plurality of lower fin tubes 216 are distributed in an annular portion on the inner wall of the return air pipe 212. Both ends of the upper fin tubes 215 and the lower fin tubes 216 are open structures, so as to facilitate through-connection of the connected fin tubes. The upper fin tubes 215 are through-connected with the air supply cavity 202, and the lower fin tubes 216 are through-connected with the return air cavity 205. Through the disassembly and assembly of the upper air inlet pipe 211 and the return air pipe 212, it is also convenient to weld and form the upper fin tubes 215 and the inner wall of the upper air inlet pipe 211, and to weld and form the lower fin tubes 216 and the inner wall of the return air pipe 212. Through the plurality of upper fin tubes 215 and the lower fin tubes 216, the contact area between the inner wall of the dehumidification pipe group 21 and the humid air is increased, thereby improving the dehumidification effect of the dehumidification pipe group 21. like Fig. 9As shown, multiple upper fin tubes 215 are inclined downward, and condensed water droplets will drip into the return air duct 212. At the same time, the water droplets condensed on the surface of multiple lower fin tubes 216 slide down the tube wall to the bottom. Multiple water guide holes 207 are reserved on the lower fin tubes 216. The water guide holes 207 pass through the lower fin tubes 216 but are not connected to the return air chamber 205. Therefore, the condensed water dripping from the upper fin tubes 215 and the condensed water sliding down the lower fin tubes 216 pass through the water guide holes 207 and are discharged through the lower air inlet 204, and finally discharged into the condensed water collection assembly 40. The contact area of ​​​​the humid air during the dehumidification process is increased by the fin tubes, and the condensed water can be discharged in time through the water guide holes 207, and the condensed water in the dehumidification tube group 21 is discharged through the lower air inlet 204 to avoid the accumulation of condensed water in the dehumidification tube group 21.

[0022] like Figure 2 , Figure 5 , Figure 6 As shown, the return air conditioning pipe group 30 includes a fan 31, which is fixed on a side of the dehumidification mechanism 10 away from the air outlet 221, and the regulating air pipe 32 is connected between the air outlet end of the fan 31 and the upper air inlet pipe 211, and the regulating air pipe 32 is connected to the air supply chamber 202, and the air inlet end of the fan 31 is connected to the three-way pipe 35, and the remaining two ends of the three-way pipe 35 are respectively connected to the external pipe 36 and the fourth valve 351, one end of the external pipe 36 is placed outdoors for extracting outdoor cold air to achieve external circulation dehumidification, wherein the fourth valve 351 is close to the evaporator 11, and the fourth valve 351 and the air outlet 221 are placed on both sides of the evaporator 11, and the return air pipe 33 is connected between the return air pipe 212 and the machine room connecting pipe group 22, and one end of the return air pipe 33 is connected to the return air chamber 205; The regulating air duct 32 is installed with a first valve 321, the outer wall of the regulating air duct 32 is wrapped with thermal insulation cotton, the return air duct 33 is installed with a second valve 331, and the external pipe 36 is installed with a fifth valve 361; like Figure 6As shown, during the internal circulation, the fifth valve 361 is in a normally closed state, the fourth valve 351, the second valve 331, and the first valve 321 are in a normally open state. During the operation of the equipment recovery system, part of the dehumidification mechanism 10 is in a negative pressure state, and the air inlet end of the fan 31 extracts part of the gas that has been dehumidified and cooled by the evaporator 11 through the fourth valve 351, and the remaining part of the gas is sucked into the condenser through the equipment recovery system for heating and drying, and then flows back to the swimming pool through the air supply pipe. The partially dehumidified gas flows into the regulating air duct 32 through the air outlet end of the fan 31, and then is transported to the air supply cavity 202, and then flows into the return air cavity 205 through the pipe cap 217, and finally flows back to the machine room connecting pipe group 22 through the return air duct 33 for mixed flow. When the cold air passes through the dehumidification pipe group 21, the inner and outer walls of the pipe, the upper fin tube 215, and the lower fin tube 216 can be cooled, and then when the high-temperature and humid air passes through the low-temperature pipe wall, the purpose of condensation and dehumidification is achieved; like Figure 4 As shown, during external circulation, that is, when the outdoor temperature is lower than the indoor temperature of the swimming pool, the fourth valve 351 is closed, and the fifth valve 361, the second valve 331, and the first valve 321 are opened. At this time, the fan 31 directly draws cold air from the outside through the external pipe 36 to cool the dehumidification pipe group 21.

[0023] It is worth noting that in the process of external circulation, in order to purify the outside air, an air filter (not shown in the figure) is connected through the air inlet end of the external pipe 36 to ensure the cleanliness of the indoor air. At the same time, through the external circulation mode, fresh air can also be delivered indoors to improve the comfort level in the hall.

[0024] The return air duct 33 is vertically connected with a double-row pipe 34 , and one end of the double-row pipe 34 is placed outdoors and between the second valve 331 and the dehumidification pipe group 21 . The double-row pipe 34 is installed with a third valve 341 .

[0025] like Figure 4 As shown, when the system performs external circulation dehumidification, the opening degree of the double-row pipe 34 is adjusted, and then the fresh air volume of the machine room connecting pipe group 22 can be adjusted. At the same time, the double-row pipe 34 is connected to the lowest point of the return air duct 33. Therefore, in this process, when the third valve 341 is opened, the condensed water in the return air duct 33 can be discharged through the double-row pipe 34. Finally, the double-row pipe 34 is used to achieve the purpose of controlling the air intake and draining water in the pipe during external circulation.

[0026] The third valve 341 is an electric ball valve, and the first valve 321 , the second valve 331 , the fourth valve 351 , and the fifth valve 361 are all electric air valves.

[0027] like Figure 3 , Fig. 9 , Fig.13 As shown, the condensed water collection assembly 40 includes a plurality of water guide plates 41, which are sequentially arranged head to tail along the dehumidification pipe group 21, and the connection is fixed by butyl tape. The water guide plate 41 is a curved surface structure, and the concave side of the water guide plate 41 is close to the lower surface of the dehumidification pipe group 21, so as to facilitate the collection of condensed water. At the same time, the separated ends of the first and last water guide plates 41 are fixedly installed with water retaining strips 44 to prevent the condensed water from flowing out through the two ends of the water guide plate 41. The end water guide plate 41 is connected with an upper drain pipe 45, and the drainage end of the upper drain pipe 45 is connected with the lower drain pipe 13 to discharge the condensed water in the water guide plate 41. At the same time, a heat preservation plate 43 is pasted on the side (lower surface) of the water guide plate 41 away from the return air pipe group 20, and the heat preservation plate 43 is used to insulate the water guide plate 41 to prevent water droplets from condensing on the lower surface of the water guide plate 41. A plurality of lower connecting members 42 are fixed on both sides of the water guide plate 41 , and the water guide plate 41 is fixed below the dehumidification pipe group 21 through the lower connecting members 42 .

[0028] like Fig.10 , Fig.11 , Fig.14 As shown, upper flanges 213 are fixed at both ends of the upper air inlet duct 211, and lower flanges 214 are fixed at both ends of the return air duct 212. The upper flange 213 and the lower flange 214 have the same structure and are both arc-shaped structures. When the upper air inlet duct 211 and the return air duct 212 are assembled, the upper flange 213 and the lower flange 214 form a flange, and the flange is welded and fixed on the edge side of the pipe cap 217. Then, through the cooperation of the flange and the bolt and nut group, the dehumidification pipe group 21 and the machine room connecting pipe group 22 and the pipe cap 217 can be disassembled and assembled.

[0029] like Figure 3 and Figure 7 As shown, it also includes a plurality of suspension rods 23 , on which the first nut 231 , the second nut 232 , and the third nut 233 are threadedly connected.

[0030] The suspension rod 23 is hoisted in the swimming pool, and the suspension rod 23 passes through the upper connecting piece 203, the fixing plate 206, and the lower connecting piece 42 in sequence. The first nut 231 is threadedly connected to the suspension rod 23 and is placed between the upper connecting piece 203 and the fixing plate 206. The second nut 232 is placed between the fixing plate 206 and the lower connecting piece 42. The third nut 233 is placed below the lower connecting piece 42. Therefore, during the installation process, the upper air inlet duct 211 can be hoisted first and positioned by the first nut 231, and then the return air duct 212 can be hoisted and positioned by the second nut 232, and finally the water guide plate 41 can be hoisted and positioned by the third nut 233. During disassembly, the dehumidification pipe group 21 can be disassembled and separated by disassembling the third nut 233, the second nut 232, and the first nut 231 in sequence, so as to facilitate cleaning of the inside of the pipe.

[0031] Working principle: (I) Internal circulation (such as Figure 6 shown); During the cooling stage of the dehumidification pipe group 21, the heat pump recovery system is running, the fourth valve 351, the second valve 331, and the first valve 321 are normally open, and the fifth valve 361 is normally closed. The fan 31 is running and extracts part of the low-temperature air after dehumidification by the evaporator 11 through the fourth valve 351, and then delivers cold air to the air supply chamber 202 through the regulating air duct 32, and cools the upper air inlet pipe 211 and the upper fin tube 215, and then the air flow passes through the pipe cap 217 and flows into the return air chamber 205, and then cools the return air pipe 212 and the lower fin tube 216, and then flows back to the machine room connecting pipe group 22 through the return air duct 33, is mixed in the mixing zone, and finally discharged through the air outlet 221; During the dehumidification stage of the dehumidification tube group 21, after the dehumidification tube group 21, the upper fin tube 215, and the lower fin tube 216 are cooled, the high-temperature and humid air in the hall is sucked into the dehumidification tube group 21 through the upper air inlet 201 and the lower air inlet 204. In this process, the high-temperature and humid air contacts the inner and outer walls of the dehumidification tube group 21, the upper fin tube 215, and the lower fin tube 216. The water vapor in the air is condensed and separated, and condensed on the tube wall. After a large amount of water is collected, it slides down. The condensed water inside the pipe flows along the inner wall of the pipe and is discharged through the water guide hole 207 and the lower air inlet 204. The condensed water on the outer wall of the pipe flows along the outer wall of the pipe to the lowest point and then drips into the water guide plate 41. Finally, the condensed water is discharged through the upper drain pipe 45. After the initial dehumidification, the humid air is condensed and dehumidified for the second time through the air outlet 221 of the machine room connecting pipe group 22 and then passes through the evaporator 11, thereby quickly reducing the humidity in the hall.

[0032] (ii) External circulation (e.g. Figure 4 shown); When the temperature difference between the outdoor and indoor temperature is large, the fifth valve 361, the third valve 341, the first valve 321, and the second valve 331 are opened, the fourth valve 351 is closed, and the fan 31 is powered on to operate. It can directly extract outdoor cold air and transport cold air to the air supply chamber 202 through the regulating air duct 32, and cool the upper air inlet pipe 211 and the upper fin tube 215. Then the airflow passes through the pipe cap 217 and flows into the return air chamber 205, and then cools the return air pipe 212 and the lower fin tube 216. Then, the condensed water and a part of the cold air are discharged to the outdoors through the double-row pipe 34 through the return air duct 33, and the other part of the fresh air flows back into the system through the return air duct 33 and the machine room connecting pipe group 22. The humid air with the fresh air passes through the evaporator 11 for secondary condensation and dehumidification, and then part of the air is sucked into the condenser by the system for heating treatment and then circulated to the swimming pool, so as to achieve the purpose of increasing fresh air indoors through external circulation.

[0033] (III) Routine operation of the system (e.g. Fig.15 shown); When the system does not need to quickly dehumidify the swimming pool, the fan 31 is stopped, and the first valve 321, the second valve 331, the third valve 341, the fourth valve 351, and the fifth valve 361 are in a normally closed state. When the system is running, the unit directly draws high-temperature and humid air through the dehumidification pipe group 21, transports it through the machine room connecting pipe group 22, and then blows it to the evaporator 11 through the air outlet 221 for condensation and dehumidification.
