Heat recovery type air cooling heat pump unit

Abstract

The invention discloses a heat recovery type air cooling heat pump unit comprising a first refrigerant circulating system and a second refrigerant circulating system, wherein the first refrigerant circulating system comprises a first compressor, a first four-way valve, a second four-way valve, a first air side fin type heat exchanger, an air conditioner side heat exchanger, a first air-liquid separator, a total heat recovery heat exchanger, a hot water circulating water pump, a heat preservation water tank and a valve; the second refrigerant circulating system comprises a second compressor, a third four-way valve, a fourth four-way valve, a second air side fin type heat exchanger, an air conditioner side heat exchanger, a third reservoir, a second air-liquid separator, a partial heat recovery heat exchanger, a heat preservation water tank and a valve. According the invention, heat is ensured to be effectively recovered and reused, and environment is protected from thermal pollution, thereby being environmental friendly and saving energy. In addition, the defects that air conditioner heating and daily hot water supply can not be carried out simultaneously, and the traditional total heat recovery air conditioner system which only has a single heat recovery system can not produce higher-temperature daily hot water at low temperature in winter can be effectively overcome.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat recovery type air-cooled heat pump unit. Background technique [0002] As an alternative means to solve heating problems, heat pumps have great advantages from both technical and economical points of view. Heat pump technology is a way to convert low-grade heat, such as air, water (including: surface water, groundwater, etc.), solar energy, soil, waste heat, etc., into high-grade heat, such as heating heat. Its working principle is: when the heat pump is running, the evaporator absorbs heat from the heat source (heat collection), and provides heat to the heat-using object. [0003] At present, with the development of social economy, more and more air-cooled heat pump units are adopted by people. In summer, when the air-cooled heat pump unit is running, it will emit a large amount of condensation heat to the environment through the air-side fin heat exchanger. Th...
