[0024] The exhaust unit includes an exhaust fan F1 and an exhaust pipe L2. The lower side of the exhaust fan F1 is connected to the exhaust pipe L2.

The right side of the exhaust pipe L2 is connected to the air source heat pump D1.

[0025] The mixing air unit includes a mixing air chamber C2 and a fresh air pipe L4. A second regulating air valve V2 is installed on the left side of the mixing air chamber C2, and the second regulating air valve is used to regulate the return air volume entering the mixing air chamber C2. The lower side of the mixing air chamber C2 is connected to the fresh air pipe L4, and a third regulating air valve V3 is installed on the fresh air pipe L4, and the third regulating air valve is used to regulate the fresh air volume entering the mixing air chamber C2.

[0026] The cooling unit includes a cooler D3. The lower side of the cooler D3 is connected to a refrigerant supply pipe P1 and a refrigerant return pipe P2, and a first electric two-way valve V4 is installed on the refrigerant supply pipe P1. The refrigerant supply pipe P1 and the refrigerant return pipe P2 are respectively connected to the air source heat pump D1.

[0027] The heating unit includes a heater D4. The lower side of the heater D4 is connected to a heat medium supply pipe P3 and a heat medium return pipe P4, and a second electric two-way valve V5 is installed on the heat medium supply pipe P3.

[0031] The floor heating unit includes a third heat medium supply pipe P7 and a third heat medium return pipe P8, and a fourth electric two-way valve V7 is installed on the third heat medium supply pipe P7. The third heat medium supply pipe P7 and the third heat medium return pipe P8 are respectively connected to the floor heating pipe P9.

[0032] The control strategy of the above-mentioned multi-functional pool heat recovery heat pump system is as follows:

[0033] When the pool is in a non-operating state, close the first regulating air valve V1 and the third regulating air valve V3, turn off the exhaust fan F1, turn on the supply fan F2, and adjust the second regulating air valve V2 to the maximum, so that the constant temperature and humidity unit D2 is in a full return air circulation state. The hot and humid air in the pool area enters the return air chamber C1 through the return air duct L1, enters the mixing air chamber C2 through the second regulating air valve V2, and enters the cooler D3. At this time, the first electric two-way valve V4 is opened, and the refrigerant from the air source heat pump D1 enters the cooler D3 through the refrigerant supply pipe P1 to cool, dehumidify and lower the temperature of the hot and humid air from the pool area. After absorbing the heat of the hot and humid air, the refrigerant returns to the air source heat pump D1 through the refrigerant return pipe P2. The air after cooling, dehumidifying and lowering the temperature enters the heater D4. At this time, the second electric two-way valve V5 is opened, and the heat medium from the air source heat pump D1 enters the heater D4 through the first heat medium supply pipe P3 to heat the dry and cold air from the cooler D3 to prevent the air sent into the room from being too cold and causing condensation indoors. After the heat medium heats the dry and cold air, it returns to the air source heat pump D1 through the first heat medium return pipe P4. The dry and hot air after being heated by the heater D4 passes through the supply fan F2 and is sent into the pool area through the supply air duct L3 to eliminate the heat and humidity load in the pool area and maintain the temperature and humidity balance indoors. On the other hand, the refrigerant that has absorbed the heat of the hot and humid air in the pool area sends the heat to the air source heat pump D1 through the refrigerant return pipe P2. The air source heat pump recovers this part of the heat and distributes it to the heater D4 through the first heat medium supply pipe P3 for heating the dry and cold air after cooling and dehumidifying. A part of the heat is sent to the pool machine room through the third electric two-way valve V6 and the second heat medium supply pipe P5 for heating the pool water. After heating, the heat medium returns to the air source heat pump D1 through the second heat medium return pipe P6. If in winter, a part of the heat can also be sent to the floor heating pipe P9 in the pool area through the third heat medium supply pipe P7 for heating the floor to improve the indoor comfort in winter. After heating the floor heating pipe P9, the heat medium returns to the air source heat pump D1 through the third heat medium return pipe P8.

[0034] In this way, when the pool is in a non-operating state, by closing the first regulating air valve, the system is in a full return air state, maximizing the use of the hot and humid air indoors to recover heat, and a large amount of energy consumption expenditure required for other systems can be saved.

[0035] When the pool is in an operating state, at this time, a certain amount of fresh air needs to be sent into the pool to meet the indoor sanitation requirements. Therefore, the first regulating air valve V1 is opened at this time, and the second regulating air valve V2 and the third regulating air valve V3 are adjusted to make the fresh air and return air reach a suitable ratio. The hot and humid air in the pool area enters the return air chamber C1 through the return air duct L1. A part of the air passes through the first regulating air valve V1 and is sent to the air source heat pump D1 through the exhaust air duct L2 under the suction of the exhaust fan F1, which can be used as a free cold source for the air source heat pump D1.

[0036] It enters the mixing air chamber C2 through the second regulating air valve V2 and then enters the cooler D3. At this time, the first electric two-way valve V4 is opened, and the refrigerant from the air source heat pump D1 enters the cooler D3 through the refrigerant supply pipe P1 to cool, dehumidify and lower the temperature of the hot and humid air from the pool area. After absorbing the heat of the hot and humid air, the refrigerant returns to the air source heat pump D1 through the refrigerant return pipe P2. The air after cooling, dehumidifying and lowering the temperature enters the heater D4. At this time, the second electric two-way valve V5 is opened, and the heat medium from the air source heat pump D1 enters the heater D4 through the first heat medium supply pipe P3 to heat the dry and cold air from the cooler D3 to prevent condensation in the room due to too low temperature of the air sent into the room. After heating the dry and cold air, the heat medium returns to the air source heat pump D1 through the first heat medium return pipe P4. The dry and hot air after being heated by the heater D4 passes through the blower F2 and is sent into the pool area through the air supply pipe L3 to eliminate the heat and humidity load in the pool area and maintain the temperature and humidity balance in the room. On the other hand, the refrigerant that has absorbed the heat of the hot and humid air in the pool area sends the heat to the air source heat pump D1 through the refrigerant return pipe P2. The air source heat pump recovers this part of the heat and distributes it to the heater D4 through the first heat medium supply pipe P3 for heating the dry and cold air after cooling and dehumidifying. A part of the heat is sent to the pool machine room through the third electric two-way valve V6 and the second heat medium supply pipe P5 for pool water heating, and after heating, the heat medium returns to the air source heat pump D1 through the second heat medium return pipe P6. If in winter, a part of the heat can also be sent to the floor heating coil P9 in the pool area through the third heat medium supply pipe P7 for heating the floor to improve the indoor comfort in winter. After heating the floor heating coil P9, the heat medium returns to the air source heat pump D1 through the third heat medium return pipe P8.

[0037] In this way, by reciprocatingly circulating to displace the heat in the indoor hot and humid air for heating the air of the pool water heater and being available for pool floor heating in winter, the excess exhaust air can be used as the free cold source of the air source heat pump, making full use of the cold and heat of the indoor air and achieving a good energy-saving and carbon-reducing effect.
