[0019] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0020] The southwest region has unique climate characteristics of cold summers and cold winters, year-round humidity, and the temperature is above 5°C most of the time during winter heating. The present invention is suitable for the cooling and heating supply and swimming pool heat exchange system in the southwest region. The swimming pool can be heated during the cooling process; during the heating process, the tower is used to absorb heat from the outside when the temperature is above 5°C, and when the heat is insufficient, it is supplemented by heat exchange with swimming pool water. The refrigeration host is equipped with an efficient siphon evaporator, which can realize the operation of water in an ice-water mixed state. When the temperature is low, antifreeze is used to achieve efficient heating of the system.

[0021] like Figure 1As shown, a cooling and heating supply and swimming pool heat exchange system includes a cooling / heat source tower 6 and a heat pump unit 17, wherein the heat pump unit 17 is provided with an evaporator 15 and a condenser 16, and the water inlet of the heat pump unit 17 is provided with a water inlet pipe group, wherein the water inlet pipe group includes a first pipe and a second pipe connected in parallel, wherein the first pipe is provided with a first valve A-1 and a sixth valve B-2 connected in series from right to left, and the second pipe is provided with a fifth valve B-1 and a second valve A-2 connected in series from right to left, and the water outlet of the heat pump unit 17 is provided with a water outlet pipe group, wherein the water outlet pipe The pipeline group includes a third pipeline and a fourth pipeline in parallel, the third pipeline is provided with a third valve A-3 and an eighth valve B-4 connected in series from right to left, the fourth pipeline is provided with a seventh valve B-3 and a fourth valve A-4 from right to left, the user side is located on the right side of the water inlet pipeline group, the cooling / heat source tower 6 is located on the left side of the water outlet pipeline group, and also includes a swimming pool 7, the outlet water of the cooling / heat source tower 6 enters the heat pump unit 17 through the tower water pump 5 and then enters the swimming pool 7, the water of the swimming pool 7 enters the heat pump unit 17 through the swimming pool water pump 9 and then enters the cooling / heat source tower 6.

[0022] In summer, the evaporator of the heat pump unit of the system directly provides cooling capacity for users through the user water pump, and the heat is normally dissipated through the cooling / heat source tower; when the temperature of the swimming pool is not enough, the swimming pool water pump is turned on to achieve the purpose of heating the swimming pool. In winter, the condenser directly provides heat for users through the user water pump. This patented heat pump unit is equipped with a siphon evaporator, which can normally keep the circulating water in an ice-water mixed state. When the outdoor temperature is high, the cold water in the evaporator circulates into the tower through the tower water pump, absorbs the latent heat and sensible heat of the air from the air, the temperature rises, the water volume increases, and the excess water flows into the swimming pool through the swimming pool water pump. When the outdoor temperature is lower than 5°C, the heat absorbed from the tower cannot meet the heating demand. At this time, the circulating water in the circulating swimming pool is used to absorb the heat in the water to achieve the purpose of heating. At the same time, hot water from the condenser is added to the solution tank in winter to melt the ice after the siphon evaporator is frozen. In extreme weather conditions in the southwest region, when the outdoor temperature is below 2°C, antifreeze is injected into the solution tank. The antifreeze absorbs heat from the air in the heat source tower, thereby satisfying the purpose of normal heating of the system.

[0023] In one embodiment, the evaporator 15 is a siphon evaporator. Figure 2 As shown, it includes a gas-liquid separator 20 and a heat exchanger 18. The liquid in the gas-liquid separator enters the copper tube in the heat exchanger 18 through a conduit. A baffle 19 is provided in the heat exchanger, and the width of the baffle increases gradually along the liquid flow direction.

[0024] The refrigerant at the condenser outlet enters the gas-liquid separator, and then the gas enters the compressor suction port from the top. The liquid in the gas-liquid separator enters the copper tube in the heat exchanger through the pipeline, and the liquid refrigerant absorbs heat and turns into gas, and then flows back to the gas-liquid separator; 3℃ cold water enters the heat exchanger and flows in a wave-like manner through the wide baffles with gradually increasing widths. The water releases heat, the temperature drops, and part of the water turns into ice and adheres to the surface of the heat exchange copper tube. At the outlet, 0℃ water in the mixed state of ice and water flows out of the heat exchanger.

[0025] There is a certain height between the gas-liquid separator and the phase change heat exchanger. The density difference between the liquid refrigerant and the gaseous refrigerant provides natural power for the entire flow, ensuring the normal and reliable operation of the entire refrigerant cycle.

[0026] This structure can realize the existence of ice-water mixture in the heat exchanger, and the flow is the flow of water, while the solid ice is attached to the surface of the heat exchange copper tube. When the thickness of the ice layer reaches a certain value, high-temperature hot water is introduced to melt the ice on the surface of the copper tube, thereby achieving the effect of absorbing heat at the freezing point of water.

[0028] In one embodiment, the user side includes a constant pressure water replenishment tank 3, and the constant pressure water replenishment tank 3 enters the water inlet pipe group through a pipe provided with a user water pump 1. When the water circulation pressure is insufficient, the system is replenished with water through the constant pressure water replenishment tank 3. The constant pressure water replenishment tank 3 is connected to the user water pump 1, and an energy meter 2 is provided between the user water pump 1 and the constant pressure water replenishment tank 3.

[0029] In one embodiment, a photovoltaic panel 21 is disposed on the periphery of the cooling / heat source tower 6. Figure 3 As shown. A small amount of circulation in the cooling / heat source tower 6 flows into the solar photovoltaic panel, which can improve the photovoltaic power generation efficiency by cooling down, and improve the evaporation temperature of the heat pump unit by absorbing the heat of the photovoltaic panel in winter, so as to achieve more efficient energy saving.

[0032] Example 2: Cooling + swimming pool heating mode; This mode is used when the pool temperature is not high in summer and needs to be heated. The main operating modes of this mode are as follows: The 12℃ chilled water comes back from the user end and then flows into the user water pump inlet. In the cooling mode, the first valve A-1, the second valve A-2, the third valve A-3 and the fourth valve A-4 are opened, and the fifth valve B-1, the sixth valve B-2, the seventh valve B-3 and the eighth valve B-4 are closed. The chilled water is pressurized by the user water pump 1 and reaches the inlet of the evaporator 15 through the first valve A-1. After the chilled water temperature is reduced to 7℃, it is supplied to the user through the third valve A-3. When the water circulation pressure is insufficient, the system is replenished with water through the constant pressure water replenishment tank 3.

After the cold water is boosted, it reaches the inlet of the unit siphon evaporator through the A-2 valve. After the cold water temperature drops to 0.5℃, it enters the inlet of the cooling / heat source tower through the eighth valve B-4.
