Abstract

The invention relates to an air source heat pump system with a heat recovery unit. The air source heat pump system comprises a compressor, an oil separator, a heat recovery heat exchanger, a four-way valve, an air-side heat exchanger, a tank-type heat exchanger and a gas-liquid separator which are connected in sequence. The oil separator is connected with an oil groove of the compressor through an adjusting device. The heat recovery heat exchanger is connected with a first port of the four-way valve. A second port, a third port and a fourth port of the four-way valve are connected with the tank-type heat exchanger, the gas-liquid separator and the air-side heat exchanger correspondingly. The air-side heat exchanger is connected with the tank-type heat exchanger through a throttling device. The tank-type heat exchanger is connected with the compressor through a return oil solenoid valve. An outlet of the gas-liquid separator is connected with an inlet of the compressor. The gas-liquid separator is located in the tank-type heat exchanger. The efficiency of the heat pump system is improved. The structure is simplified. The material cost is lowered. The use safety performance and reliability of the heat pump are improved.

Description

technical field [0001] The invention relates to a heat pump system, in particular to an air source heat pump system with a heat recovery device. Background technique [0002] Air source heat pump is an energy-saving and environment-friendly heating equipment that can replace coal-fired oil-fired boilers and use air energy to produce hot water. Heat pumps with heat recovery can provide hot water during cooling in summer and heating in winter When providing hot water, hot water can be used as domestic water or heating, which brings convenience to users and improves unit efficiency. At present, air source heat pumps generally use dry heat exchangers, which have low heat exchange efficiency, large pipeline losses, and high operating costs. The structural system and control of air source heat pumps with heat recovery are more complicated and costly. The charging amount is too large, and the use of a three-way valve increases the cost of the unit, which hinders the development of...
