Latest company news about What are the characteristics of dual source heat pump cascade utilization hot water all-in-one machine?

The company has developed an integrated machine for cascade utilization of heat energy of double source heat pump, which is characterized by an integrated machine composed of double source heat pump water heater and clean water preheater; The double source heat pump water heater includes two evaporators with a water source heat exchanger and an air source heat exchanger. The refrigerant circuits of the two four-way valves are: the first, second, third and fourth interfaces of the first four-way valve are respectively connected with the exhaust port of the compressor, the inlet of the condenser hot water heat exchanger, the upper interface of the air source heat exchanger and the inlet of the gas-liquid separator; The refrigerant outlet of the hot water heat exchanger is connected with the liquid reservoir and filter, and then the throttle inlet; The first, second, third and fourth interfaces of the second four-way valve are respectively connected with the outlet of the restrictor, the lower interface of the air source heat exchanger, the lower interface of the water source heat exchanger and the upper interface of the water source heat exchanger; The refrigerant circuit of the unit or other five structures provided by the utility model can be selected; The inlet water of the all-in-one machine is heated twice by waste water clean water heat exchanger and hot water heat exchanger; Waste hot water is recovered by two stages of waste water clean water heat exchanger and water source heat exchanger; COP? 5 ~ 6 are high-efficiency, energy-saving and cheap hot water equipment.
