Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning dehumidifiers, and particularly to a special constant-temperature air-conditioning dehumidifier for a swimming pool hall with constant-temperature pool water. Background Art

[0002] The constant-temperature air-conditioning dehumidifier processes air through an evaporator and a condenser to achieve the purpose of temperature adjustment and dehumidification. When the indoor humid air passes through the surface of the evaporator, since the temperature of the evaporator is lower than the dew point temperature of the humid air, the water vapor in the air condenses and separates out, accumulates in the water receiving tray, and is discharged through a water pipe, reducing the moisture content of the air. At the same time, the equipment recovers the condensation heat of the system to make up for the heat lost in the air during cooling and dehumidification, thus achieving an efficient and energy-saving dehumidification effect.

[0003] Swimming pool halls usually have a large area and extremely high humidity. When the condensation dehumidifier processes a large amount of humid air, its dehumidification efficiency cannot meet the requirement of quickly reducing humidity. This results in a high-humidity environment being maintained in the swimming pool hall for a long time, which is not conducive to the health of athletes and the maintenance of equipment.

[0046] Next, the accompanying drawings in the embodiments of the present invention will be combined to clearly and completely describe the technology in the embodiments of the present invention: a dedicated constant - temperature air - conditioning dehumidifier for a swimming pool hall with constant - temperature pool water. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0047] As Figure 1 - Figure 14 shown, the present invention provides: a dedicated constant - temperature air - conditioning dehumidifier for a swimming pool hall with constant - temperature pool water, including a dehumidification mechanism 10 and a return air duct group 20. The dehumidification mechanism 10 includes an evaporator 11 fixed inside the housing 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 - hole to a lower drain pipe 13 for discharging condensate water. The return air duct group 20 includes 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 thin plate. The dehumidification pipe group 21 made of stainless - steel thin plate has the advantages that it is not easy to rust, has a low cost, and has good heat transfer effect. The dehumidification pipe group 21 is exposed in the indoor swimming pool hall. Through the contact between the inner wall and the outer wall of the pipe and the humid air, the humid air is condensed and dried, reducing the humidity of the air entering the evaporator 11 and performing primary dehumidification.

[0048] The dehumidification pipe group 21 is connected through - hole to a machine room connecting pipe group 22. The machine room connecting pipe group 22 is used to connect the dehumidification pipe group 21 and the machine room. The machine room connecting pipe group 22 has multiple sections and is located outside the indoor swimming pool hall. In order to avoid a large amount of heat loss of the humid air when passing through the machine room connecting pipe group 22, a layer of thermal insulation is wrapped on the surface of the machine room connecting pipe group 22 to avoid the problem of frosting on the surface of the evaporator 11 caused when the temperature of the humid air drops and then passes through the evaporator 11.

[0049] The dehumidification tube group 21 includes a supply air chamber 202 and a return air chamber 205 that are interconnected. Both ends of the supply air chamber 202 and the return air chamber 205 are open structures. By adjusting the air temperature in the supply air chamber 202 and the return air chamber 205 through the return air conditioning tube group 30, the temperature of the entire surface of the dehumidification tube group 21 can be adjusted. When the surface temperature of the dehumidification tube group 21 is lower than the temperature of the humid air, the water vapor in the humid air will condense and separate out;

[0050] On one side of the evaporator 11 (the side close to the air supply duct), the return air conditioning tube group 30 is fixedly installed. The air outlet 221 of the machine room connection tube group 22 is located on the other side of the evaporator 11 (the side far from the air supply duct), and at the same time, the air outlet 221 is located above the water receiving tray 12. The condensed water in the return air duct group 20 drips into the water receiving tray 12 through the air outlet 221. The return air conditioning tube group 30 is connected to the supply air chamber 202 and the return air chamber 205 in a through manner. The return air conditioning tube group 30 is used for adjusting the air in the supply air chamber 202 and the return air chamber 205. The return air conditioning tube group 30 absorbs cold air and conveys the cold air into the supply air chamber 202. The supply air chamber 202 cools the dehumidification tube group 21 when flowing through the return air chamber 205. The temperature of the surface of the dehumidification tube group 21 is lower than the dew point temperature of the humid air. At this time, water droplets condense on the inner wall and surface of the dehumidification tube group 21 to complete the primary dehumidification;

[0051] Finally, through the cooperation of the return air conditioning tube group 30, it flows back into the machine room connection tube group 22 for mixing and is dehumidified again by the evaporator 11;

[0052] By contacting the dehumidification tube group 21 with the indoor humid air, the condensation contact area is increased, and the dehumidification tube group 21 first dehumidifies the humid air, and then is dehumidified again by the evaporator 11, so that the air humidity in the swimming pool can be quickly reduced;

[0053] When the dehumidification tube group 21 is dehumidifying, a large amount of water droplets condense on the surface and drip into the fixed condensate water collection assembly 40 below the dehumidification tube group 21 under the action of gravity. Then, the condensate water collection assembly 40 can centrally discharge the condensate water collected during the dehumidification process of the dehumidification tube group 21.

[0054] Such as Figure 7 - Figure 12As 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.

[0055] 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;

[0056] 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.

[0057] like Figure 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.

[0058] like Figure 7 - Figure 12As shown in the figure, a plurality of upper finned tubes 215 are annularly distributed on the inner wall of the upper air inlet pipe 211, and a plurality of lower finned tubes 216 are annularly distributed on a part of the inner wall of the return air pipe 212. Both ends of the upper finned tubes 215 and the lower finned tubes 216 are open structures, so as to facilitate the through connection of the connected finned tubes. The upper finned tubes 215 are in through connection with the air supply chamber 202, and the lower finned tubes 216 are in through connection with the return air chamber 205. By disassembling and assembling the upper air inlet pipe 211 and the return air pipe 212, it is also convenient for the welding and forming of the upper finned tubes 215 on the inner wall of the upper air inlet pipe 211 and the welding of the lower finned tubes 216 on the inner wall of the return air pipe 212. Through the plurality of upper finned tubes 215 and the lower finned tubes 216, the contact area between the inner wall of the dehumidification tube group 21 and the humid air is increased, thereby improving the dehumidification effect of the dehumidification tube group 21;

[0059] As Figure 9 shown in the figure, a plurality of upper finned tubes 215 are inclined downward, and the condensed water droplets will drip into the return air pipe 212. At the same time, the condensed water droplets on the surface of the plurality of lower finned tubes 216 slide down along the pipe wall to the bottom. A plurality of water guide holes 207 are reserved on the lower finned tubes 216. The water guide holes 207 pass through the lower finned tubes 216 but are not communicated with the return air chamber 205. Therefore, the condensed water dripped from the upper finned tubes 215 and the condensed water slid from the lower finned tubes 216 are discharged through the water guide holes 207 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 through the finned tubes, and the condensed water can be discharged in time through the water guide holes 207. The condensed water in the dehumidification tube group 21 is discharged through the lower air inlet 204, avoiding the accumulation of condensed water in the dehumidification tube group 21.

[0060] As Figure 2 、 Figure 5 、 Figure 6 shown in the figure, the return air conditioning tube group 30 includes a fan 31. The fan 31 is fixedly arranged on the side of the dehumidification mechanism 10 away from the air outlet 221. An adjusting air duct 32 is connected between the air outlet end of the fan 31 and the upper air inlet pipe 211, and the adjusting air duct 32 is in through connection with the air supply chamber 202. The air inlet end of the fan 31 is in through connection with a tee pipe 35. The remaining two ends of the tee pipe 35 are respectively in through connection with an external connecting pipe 36 and a fourth valve 351. One end of the external connecting pipe 36 is placed outdoors for extracting cold air outdoors to realize the dehumidification of the external circulation type. Among them, the fourth valve 351 is close to the evaporator 11, and the fourth valve 351 and the air outlet 221 are arranged on both sides of the evaporator 11. A return air duct 33 is in through connection between the return air pipe 212 and the machine room connecting pipe group 22, and one end of the return air duct 33 is in through connection with the return air chamber 205;

[0061] A first valve 321 is installed on the adjusting air duct 32, the outer wall of the adjusting air duct 32 is wrapped with heat insulation cotton, a second valve 331 is installed on the return air duct 33, and a fifth valve 361 is installed on the external connecting pipe 36;

[0062] As Figure 6 shown, during the inner cycle, the fifth valve 361 is in a normally closed state, and 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. 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. The remaining gas is inhaled into the condenser through the equipment recovery system for heating and drying, and then flows back into the swimming pool through the air supply duct. Part of the dehumidified gas flows into the adjustment air duct 32 through the air outlet end of the fan 31, then is transported to the air supply chamber 202, and then flows into the return air chamber 205 through the pipe cap 217. Finally, it flows back into the machine room connecting pipe group 22 through the return air duct 33 for mixing. When the cold air passes through the dehumidification pipe group 21, it can cool the inner and outer walls of the pipe, the upper finned pipe 215, and the lower finned pipe 216. Thus, when the high-temperature and humid air passes through the low-temperature pipe wall, the purpose of condensation dehumidification is achieved;

[0063] As Figure 4 shown, during the outer cycle, that is, when the outdoor temperature is lower than the indoor temperature of the swimming pool, the fourth valve 351 is closed at this time, and the fifth valve 361, the second valve 331, and the first valve 321 are opened. At this time, the fan 31 directly extracts the cold air from the outside through the external connection pipe 36 to cool the dehumidification pipe group 21.

[0064] It should be noted that during the outer cycle, 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 connection pipe 36 to ensure the cleanliness of the indoor air. At the same time, through the outer cycle mode, fresh air can also be transported into the room to improve the comfort level in the hall.

[0065] 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 is also placed between the second valve 331 and the dehumidification pipe group 21. A third valve 341 is installed on the double-row pipe 34.

[0066] As Figure 4 shown, when the system performs dehumidification in the outer cycle mode, by adjusting the opening degree of the double-row pipe 34, 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 through the lowest point of the return air duct 33. Therefore, during 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, through the double-row pipe 34, the purpose of controlling the air intake volume and draining the pipe during the outer cycle is achieved.

[0067] Among them, 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.

[0068] As Figure 3 , Figure 9 , Figure 13 shown, the condensate water collecting assembly 40 includes a plurality of water guiding trays 41. The plurality of water guiding trays 41 are arranged in sequence along the dehumidifying pipe group 21 from head to tail, and the connection parts are bonded and fixed by butyl tape. The water guiding tray 41 has an arc-shaped structure, and the concave side of the water guiding tray 41 is close to the lower surface of the dehumidifying pipe group 21, so as to facilitate the collection of condensate water. At the same time, water retaining strips 44 are fixedly installed at the separated ends of the two water guiding trays 41 at the head and tail to prevent the condensate water from flowing out through the two ends of the water guiding tray 41. The end water guiding tray 41 is connected through a through upper drain pipe 45, and the drainage end of the upper drain pipe 45 is connected through with the lower drain pipe 13 to discharge the condensate water in the water guiding tray 41. At the same time, a heat preservation board 43 is pasted on the side (lower surface) of the water guiding tray 41 far away from the return air duct group 20. Through the heat preservation of the heat preservation board 43 on the water guiding tray 41, water droplets are prevented from condensing on the lower surface of the water guiding tray 41;

[0069] A plurality of lower connectors 42 are fixed on both sides of the water guiding tray 41, and the water guiding tray 41 is fixed below the dehumidifying pipe group 21 through the lower connectors 42.

[0070] As Figure 10 , Figure 11 , Figure 14 shown, upper flanges 213 are fixed at both ends of the upper air inlet pipe 211, and lower flanges 214 are fixed at both ends of the return air duct 212. The upper flanges 213 and the lower flanges 214 have the same structure and are both arc-shaped structures. When the upper air inlet pipe 211 and the return air duct 212 are assembled, the upper flanges 213 and the lower flanges 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 dehumidifying pipe group 21, the machine room connecting pipe group 22 and the pipe cap 217 can be disassembled and assembled.

[0071] As Figure 3 and Figure 7 shown, it further includes a plurality of suspension rods 23, and first nuts 231, second nuts 232 and third nuts 233 are threadedly connected to the suspension rods 23.

[0072] The suspension rods 23 are hoisted in the swimming pool, and the suspension rods 23 sequentially pass through the upper connectors 203, the fixing plates 206 and the lower connectors 42. The first nuts 231 are threadedly connected to the suspension rods 23 and are placed between the upper connectors 203 and the fixing plates 206. The second nuts 232 are placed between the fixing plates 206 and the lower connectors 42. The third nuts 233 are placed below the lower connectors 42. Therefore, during the installation process, the upper air inlet pipe 211 can be hoisted first and positioned by the first nuts 231, then the return air duct 212 can be hoisted and positioned by the second nuts 232, and finally the water guiding tray 41 can be hoisted and positioned by the third nuts 233;

[0073] When disassembling, the dehumidification tube group 21 can be disassembled and separated by sequentially disassembling the third nut 233, the second nut 232, and the first nut 231, so as to facilitate the cleaning of the inside of the tube.

[0074] Working principle:

[0075] (1) Inner circulation (as Figure 6 shown);

[0076] During the cooling stage of the dehumidification tube group 21, the heat pump recovery system operates. The fourth valve 351, the second valve 331, and the first valve 321 are normally open, the fifth valve 361 is normally closed, the fan 31 operates and extracts part of the low-temperature air dehumidified by the evaporator 11 through the fourth valve 351, and then conveys cold air into the air supply chamber 202 through the regulating air duct 32, and cools the upper air inlet duct 211 and the upper fin tube 215. Then the air flow flows into the return air chamber 205 through the pipe cap 217, and then cools the return air duct 212 and the lower fin tube 216, and then returns to the machine room connecting pipe group 22 through the return air duct 33. After mixing in the mixing area, it is finally discharged through the air outlet 221;

[0077] During the dehumidification stage of the dehumidification tube group 21, when 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 tube is inhaled into the dehumidification tube group 21 through the upper air inlet 201 and the lower air inlet 204. During this process, after 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 condenses and separates out, and condenses on the tube wall. When a large amount of water vapor accumulates, it slides downwards. The condensed water inside the pipe flows along the inner wall of the pipe, and is discharged through the water guiding 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 guiding tray 41, and finally the condensed water is discharged through the upper drain pipe 45;

[0078] The humid air after primary dehumidification is secondarily condensed and dehumidified after passing through the evaporator 11 through the air outlet 221 of the machine room connecting pipe group 22, so as to quickly reduce the humidity in the hall.

[0079] (2) Outer circulation (as Figure 4 shown);

[0080] When the temperature difference between the outside and the inside of the hall 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 and operates. Cold air from the outside can be directly extracted, and through the adjustment of the air duct 32, cold air is conveyed into the air supply chamber 202, and the upper air inlet duct 211 and the upper finned tube 215 are cooled. Then the air flow flows into the return air chamber 205 through the pipe cap 217. Subsequently, the return air duct 212 and the lower finned tube 216 are cooled, and then through the return air duct 33, the condensed water and a part of the cold air are discharged to the outside through the double-row pipe 34. Another part of the fresh air returns to the system through the return air duct 33 and the machine room connection pipe group 22. The humid air with fresh air undergoes secondary condensation and dehumidification through the evaporator 11. Then part of the air is sucked by the system to the condenser for heating treatment and then recycled into the swimming pool hall, so as to achieve the purpose of increasing fresh air in the room through external circulation.

[0081] (3) System normal operation (as Figure 15 shown);

[0082] When the system does not need to quickly dehumidify the swimming pool hall, at this time the fan 31 stops running, and the first valve 321, the second valve 331, the third valve 341, the fourth valve 351, and the fifth valve 361 are in the normally closed state. When the system is running at this time, the unit directly extracts the high-temperature and humid air through the dehumidification pipe group 21, conveys it through the machine room connection pipe group 22, and then blows it to the evaporator 11 through the air outlet 221 for condensation and dehumidification.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
