Or the water in the fourth heat exchange channel 222 exchanges heat directly with the refrigerant in the first heat exchange channel 211. However, in the above two cases, the temperature at which the water can be heated is limited, and therefore, the second compressor 240 is connected in series in the pipe between the outlet of the second heat exchange channel 212 and the inlet of the third heat exchange channel 221, the second compressor 240 compresses the gaseous refrigerant in the pipe at the outlet of the second heat exchange channel 212 into a high-temperature and high-pressure gaseous refrigerant, and the high-temperature and high-pressure gaseous refrigerant flows to the third heat exchange channel 221 and exchanges heat with the water in the fourth heat exchange channel 222, so that the water can be further heated and heated.

The refrigerant in the pipeline of the hot water module 200 exchanges heat with the refrigerant in the first heat exchange channel 211 through the second heat exchange channel 212, at this time, the refrigerant absorbs heat and evaporates into a gaseous refrigerant, and then the gaseous refrigerant compressed into a high-temperature high-pressure by the second compressor 240 flows to the third heat exchange channel 221 and exchanges heat with water in the fourth heat exchange channel 222, at this time, the water in the fourth heat exchange channel 222 absorbs heat and flows back to the water tank 231 to be stored under the action of the water pump 232, when the temperature of the water in the water tank 231 reaches the target temperature of the hot water, the water outlet valve 2318 and the water return valve 2317 are closed, and the drain valve 2319 is opened to start supplying the hot water. And the high-temperature and high-pressure gaseous refrigerant in the third heat exchange channel 221 releases heat and is condensed into liquid refrigerant to return to the second heat exchange channel 212 again, so that a heating cycle is formed. By adjusting the frequencies of the first compressor 110 and the second compressor 240, waste heat of the evaporative cooling unit 100 is recovered and used for heating water in the hot water module 200, which is beneficial to saving energy consumption.

For example, when the winter non-hot water supply mode is operated, the first, fourth and

sixth control valves

140, 420 and 520 are opened, and the second, third, fifth and

fourth control valves

250, 410, 510, the outlet valve 2318 and the return valve 2317 are closed. The fluorine pump 310 acts as a power source to the refrigerant, and the refrigerant flows through the pipelines of the evaporative cooling unit 100 and the fluorine pump module 300.

The circulation cooling in the embodiment can fully utilize the natural cold source at low outdoor temperature to realize natural cooling, and the power consumption is relatively smaller than that of the compressor, thereby being beneficial to saving energy consumption.

For example, when the winter hot water supply mode is operated, the second control valve 250, the fourth control valve 420, the sixth control valve 520, the water outlet valve 2318 and the water return valve 2317 are opened, the first control valve 140, the third control valve 410, the sixth control valve 520 and the water discharge valve 2319 are closed, the fluorine pump 310 applies work to the refrigerant to enable the refrigerant to flow in the pipeline, the refrigerant flows to the indoor heat exchanger 130 through the third branch and exchanges heat with indoor air, at the moment, the refrigerant absorbs heat emitted by indoor electronic equipment and evaporates into gaseous refrigerant, the gaseous refrigerant flows to the outdoor heat exchanger 120 through the second branch and exchanges heat with outdoor air, at the moment, the outdoor air temperature is low, the gaseous refrigerant releases heat and is condensed into liquid refrigerant, the liquid refrigerant exchanges heat again through the gaseous refrigerant in the first heat exchange channel 211 and the second heat exchange channel 212, and returns to the fluorine pump 310 through the second branch after heat exchange, and accordingly, cyclic refrigeration is achieved. It can be understood that the refrigerant of the hot water module 200 absorbs heat in the second heat exchange channel 212 and evaporates into a gaseous refrigerant, the gaseous refrigerant flows to the second compressor 240 and is compressed into a high-temperature and high-pressure gaseous refrigerant, the high-temperature and high-pressure gaseous refrigerant flows to the third heat exchange channel 221 and exchanges heat with water in the fourth heat exchange channel 222, at this time, the high-temperature and high-pressure gaseous refrigerant releases heat and is condensed into a liquid refrigerant, water in the fourth heat exchange channel 222 is heated, and the liquid refrigerant flows to the second heat exchange channel 212 and continues to exchange heat with the refrigerant in the first heat exchange channel 211, so as to implement a heating cycle. The heated water is returned to the water tank 231 by the water pump 232 to be stored. When the temperature of the water in the water tank 231 reaches the target temperature of the hot water, the outlet valve 2318 and the return valve 2317 are closed, and the drain valve 2319 is opened to start the supply of the hot water.
