[0014] When the present invention is used, after the fan A2 of the combined air-conditioning fresh air unit 1 is running, warm and humid air in the swimming pool hall 10 is drawn in. The air flows through the dehumidification coil 5, and the heat is absorbed by the cold water in the dehumidification coil 5, causing the air temperature to drop rapidly below its dew point, and condensation occurs on the dehumidification coil 5. The formed condensed water is separated from the air to complete the air dehumidification process. After the air is dehumidified, it flows through the heating coil 4 and is then sent back to the swimming pool hall 10 by the air supply pipe 9. When dehumidification is required, the circulating cold water generated by the air source heat pump 17 is pumped into the water pump A18. Under the action of the water pump 17, the cold water flows out from the water outlet B25, absorbs the heat of the indoor air through the dehumidification coil 5, and then returns to the air source heat pump 17 through the water outlet A24 of the air source heat pump 17 for circulating refrigeration, so that the temperature of the cold water is always lower than the dew point temperature to achieve the dehumidification purpose. When the humidity meets the requirements, the water pump A18 stops working, the water in the water outlet A24, the water outlet B25 and the dehumidification coil 5 is in a stopped state, the air source heat pump 17 stops the cold water refrigeration cycle, the cold water temperature will gradually rise and be higher than the dew point temperature, thereby achieving the purpose of stopping dehumidification.

[0015] When the indoor temperature only needs to be cooled, the circulating cold water generated by the air source heat pump 17 flows out from the water port B25 of the air source heat pump 17 under the action of the water pump A18, absorbs the heat of the indoor air through the dehumidification coil 5, and then returns to the air source heat pump 17 from the water port A24 of the air source heat pump 17 for circulating refrigeration, so that the temperature of the cold water is always lower than the indoor temperature and higher than the dew point temperature to achieve the purpose of cooling the air. When the indoor temperature no longer needs to be cooled, the water pump A18 stops working, the water in the water ports A24, B25 and the dehumidification coil 5 is in a stopped state, the air source heat pump 17 stops the cold water refrigeration cycle, the cold water temperature will gradually rise and gradually approach the indoor temperature, achieving the purpose of stopping air cooling;

[0016] When the indoor temperature needs to be heated, the circulating hot water generated by the air source heat pump 17 flows out from the water port D27 of the air source heat pump 17 under the action of the water pump B19, flows through the solenoid valve A21, and heats the indoor air in the heating coil 4, and the temperature is reduced. It flows through the solenoid valve B22, the plate heat exchanger 28, and the water port C26 and returns to the air source heat pump 17 unit for circulating heating so that the water temperature is always higher than the indoor set temperature, thereby achieving the purpose of heating the indoor air temperature. When the indoor temperature no longer needs to be heated, the air source heat pump 17 stops circulating heating or the hot water no longer flows through the solenoid valve B22 and the heating coil 4, thereby achieving the purpose of stopping air heating;

[0017] The fresh air duct 6 is provided with a primary air filter 29 and a secondary air filter 30. The primary air filter 29 uses primary filtration to filter dust particles larger than 5μm, and the secondary air filter uses medium filtration to filter dust particles with a particle size of 1 to 5um. When the air flows through the fresh air duct 6 and the return air duct 8, the dust particles will be filtered in time. A PM2.5 concentration detection point is set in the swimming pool. When the indoor PM2.5 concentration detection value is close to the set value, the equipment is upgraded to replace or clean the filter net to ensure that the filter net is always in an effective filter state to achieve the purpose of air cleanliness adjustment.

[0018] When the swimming pool water temperature needs to be heated, the circulating hot water generated by the air source heat pump 17 flows out from the water port D27 of the air source heat pump 17 under the action of the water pump B19, flows through the solenoid valve C23 and the solenoid valve B22, and exchanges heat with the hot water of the swimming pool 11 in the plate heat exchanger 28, so that the swimming pool hot water is heated. The temperature of the circulating hot water generated by the air source heat pump 17 is always higher than the swimming pool hot water temperature; when the swimming pool water temperature does not need to be heated, the circulating hot water generated by the air source heat pump 17 no longer flows through the plate heat exchanger 28, and no heat exchange occurs, thereby achieving the purpose of regulating the indoor swimming pool water temperature;

[0019] When the swimming pool water needs to be replenished, the municipal tap water 12 flows through the water treatment system A13 and is filtered, and then enters the swimming pool 11. When the swimming pool 11 is circulating and heated, under the action of the water pump C20, the water in the swimming pool 11 flows from the water inlet 15 through the water treatment system B14 and is filtered and sterilized, and then enters the swimming pool 11 through the return water port 16.

[0020] This patent can adjust the indoor air temperature, air humidity and other six aspects of the swimming pool 11, comprehensively improving the comfort of the indoor children's swimming pool. When dehumidification is required, the circulating cold water generated by the air source heat pump 17 flows out from the air source heat pump 17 water port B25 under the action of the water pump A18, absorbs the indoor air heat through the dehumidification coil 5, and then returns to the air source heat pump 17 from the air source heat pump 17 water port A24 for circulating refrigeration, so that the temperature of the cold water is always lower than the dew point temperature to achieve the purpose of dehumidification. When the indoor temperature needs to be heated, the circulating hot water generated by the air source heat pump 17 flows out from the water pump B19 Under the action of, it flows out from the water outlet D27 of the air source heat pump 17, flows through the solenoid valve A21, heats the indoor air in the heating coil 4 and then the temperature decreases. It flows through the solenoid valve B22, the plate heat exchanger 28 and the water outlet C26 and returns to the air source heat pump 17 for circulation heating so that the water temperature is always higher than the indoor set temperature, thereby achieving the purpose of heating the indoor air temperature. When the indoor temperature no longer needs to be heated, the air source heat pump 17 stops circulating heating or the hot water no longer flows through the solenoid valve B22 and the heating coil 4, thereby achieving the purpose of stopping air heating and other adjustments, thereby meeting the use of the children's swimming pool.
