[0030] The working principle of this utility model:

[0031] Cooling mode:

[0032] First, the compressor 1 compresses the refrigerant into a high-temperature and high-pressure gas, and transports the refrigerant to the outdoor heat exchanger 5 outdoors through the switching channels of the first reversing valve 2, the second reversing valve 3, and the third reversing valve 4 to exchange heat with the environment for cooling. Then, by closing the second throttle valve 14, the refrigerant is allowed to flow to the liquid storage tank 16 through the one-way valve 10 pipeline. Then, the first one-way valve 11 and the second one-way valve 12 are used to prevent the refrigerant from flowing into the dehumidification heat exchanger 7 and the pool water heat exchanger 8. After the refrigerant flows to the first throttle valve 15, it is throttled to obtain a low-temperature and low-pressure gas-liquid two-phase medium. Then, the refrigerant flows to the first heat exchanger 6, and the user's indoor air is cooled through the heat exchanger 6 by the fan 18 to achieve the indoor set temperature required by the customer.

[0033] Heating mode:

[0034] First, the compressor 1 compresses the refrigerant into a high-temperature and high-pressure gas, and transports the refrigerant to the first heat exchanger 6 through the switching channels of the first reversing valve 2, the second reversing valve 3, and the third reversing valve 4. The air supply fan 18 passes the user's indoor air through the heat exchanger 6 for winter heating treatment to reach the indoor set temperature required by the customer. Then the refrigerant condenses and flows to the third one-way valve 17 pipeline, while the first throttle valve 15 is in a closed state to prevent the refrigerant from flowing in the wrong direction. The refrigerant flows to the second throttle valve 14 channel to the outdoor heat exchanger 5, and finally returns to the compressor 1 to form a cycle.

[0035] The dehumidification mode first cools down and then heats up:

[0036] First, the compressor 1 compresses the refrigerant into a high-temperature and high-pressure gas, and then delivers the refrigerant to the dehumidification heat exchanger 7 through the first reversing valve 2 and the second reversing valve 3. The refrigerant then flows to the liquid storage tank 16 and the first throttle valve 15 in turn and then enters the first heat exchanger 6. The refrigerant finally returns to the compressor 1 to form a cycle. As for the user-side air duct, the indoor return air is cooled by the heat exchanger 6, and the dehumidification effect is achieved by the dehumidification heat exchanger 7, and the dry and high-temperature air is delivered to the user side to form a cycle.

[0037] At this time, the on-site environment will continue to rise. When it reaches a certain temperature, the unit will frequently switch to cooling mode to cool down. For this reason, the number of multifunctional swimming pool heat pump units is set to two groups, one of which uses heating and dehumidification, and the other uses cooling and dehumidification. The combination of the two groups can ensure both the dehumidification capacity and the constant temperature environment of the user's air outlet temperature. Cooling and dehumidification can also recover heat from the pool to heat the water temperature, meeting the maximum utilization of energy efficiency.

[0038] Pool water heating mode:

[0039] Compressor 1 compresses the refrigerant into a high-temperature and high-pressure gas, and transports the refrigerant to the pool water heat exchanger 8 through the switching channel of the reversing valve 2 to heat it with the pool water. The refrigerant then flows through the fourth one-way valve 12 and the liquid reservoir 16 to the throttle valve 14 pipeline. After the refrigerant flows to the second throttle valve 14, it is throttled to obtain a low-temperature and low-pressure gas-liquid two-phase medium, which flows to the outdoor heat exchanger 5. The refrigerant returns to compressor 1 to form a cycle.

[0040] When in use, the compressor 1 is placed on the top of the connecting plate 19 and fixed by bolts. After the fixing is completed, the connecting plate 19 is docked with the sliders 903 on both sides and fixed by the clamping plate 25 and bolts. Then, the rotating motor 211 is started. The rotating motor 211 will drive the transmission gear 212 to rotate through its own output end, and the transmission gear 212 will drive the connecting gear 901 to rotate through the chain 213 during the rotation. During the rotation, the connecting gear 901 will ensure its own rotation stability through the rotating shaft block 22 and drive the screw rod 902 to rotate. When the screw rod 902 rotates, it will drive the slider 903 to move up and down through the threaded connection with the slider 903. The slider 903 is fixed to the connecting plate 19 through the clamping plate 25. Therefore, during the movement, the slider 903 will drive the connecting plate 19 to follow the movement, so as to achieve the effect of quickly adjusting the installation height of the compressor 1 through the lifting degree of the connecting plate 19, so that the compressor 1 can be adapted to use with a variety of conveying equipment of different heights after installation, thereby improving the convenience of use of the compressor 1.

[0041] The specific model and specifications of the rotating motor 211 proposed in this application need to be selected and determined based on the actual specifications of the device. The specific selection calculation method, line connection method and control method all adopt the existing technology in this field, so they will not be described in detail.
