Specifically, the bottle washer heat recovery system 100 comprises a low-temperature heat energy tank 1, a high-temperature heat energy tank 2, a first heat exchanger 3, a second heat exchanger 4, a flue gas heat exchanger 5 and two water source heat pumps. The low-temperature heat energy tank 1 can be used as a water return point of a bottle washer or other systems to collect various hot water after use (the water return temperature is generally in the range of 73-83 ℃). The high-temperature heat energy tank 2 can be used as a water supply point of a bottle washer or other systems to provide high-temperature hot water (generally, the water outlet temperature is about 90 ℃).
And each water source heat pump realizes heat transfer between the heat transfer water and the first heat exchanger, the second heat exchanger and the flue gas heat exchanger. Each of the water source heat pumps includes an evaporator 61, a compressor 62, a condenser 63, and a throttle valve 64, and the evaporator 61, the compressor 62, the condenser 63, and the throttle valve 64 are in fluid communication in sequence and form a circulation circuit for the flow of refrigerant. Wherein the evaporator 61 is used for heat exchange between the refrigerant and the heat transfer water to absorb heat of the heat transfer water; the compressor 62 serves to increase the fluid pressure of the refrigerant and to deliver the refrigerant to the condenser 63; the water inlet and the water outlet of the condenser 63 are respectively communicated with the low-temperature heat energy tank 1 and the high-temperature heat energy tank 2 to heat the hot water from the low-temperature heat energy tank 1 by using the recovered heat; the throttle valve 64 serves to reduce the fluid pressure of the refrigerant. Wherein, each water source heat pump provided in this embodiment is a hydrofluoroolefin refrigerant water source heat pump, the hydrofluoroolefin refrigerant has a lower GWP value (global warming potential), and the outlet water temperature of the hydrofluoroolefin refrigerant water source heat pump can reach 100 ℃.
The first heat exchanger 3 supplies heat transfer water to exchange heat with purified water to recover heat of the purified water. Specifically, the first heat exchanger 3 is configured with a first circuit (not shown in the figure) and a second circuit (not shown in the figure) that are independent of each other and can perform heat exchange, and the water outlets of the evaporators 61 are all in fluid communication with the water inlets of the first circuit in the first heat exchanger 3. The water inlet and the water outlet of the second loop in the second heat exchanger 3 are respectively in fluid communication with the purified water outlet 20 and the purified water inlet 10 of the bottle washing machine.
