Booster compressor, the natural gas engine, the compressor are sequentially connected, and are additionally provided with cooling on the natural gas engine
Water jacket, the cooling jacket and expansion tank, the first air cooling heat exchanger, filter, first circulation water pump, flue gas heat-exchange unit are successively
Connection composition the recovery of residual heat from gas engine circulatory system, the compressor also with four-way valve, condenser, throttle valve, evaporator
It is sequentially communicated the heat pump circulating system of composition coupling waste heat recycling, the condenser also air-cooled is changed with second circulation water pump, second
The family of hot device composition closure warms oneself the circulatory system, the evaporator and the air that is heated by the described first air-cooled heat exchanger into
Row heat exchange.
The booster compressor is oilless (oil free) compressor, and the booster compressor is also connect with natural gas air inlet pipe.
Pipeline connection, the circulation cycle water in pipeline are all made of between above-mentioned various components.
Beneficial effect is:
Engine driven supercharging formula gas engine heat pump system provided by the invention increases natural gas relative to traditional gas engine heat pump system
Function of increasing pressure directly drives heat pump, the further genralrlization use scope of gas-fired heat pump using natural gas in home to realize；
The heat source of heat pump system provided by the invention is air and natural gas engine waste heat, relative to individual air-source heat
Pump, improve evaporating temperature, thus ensure that proposed heat pump system can under cold snap weather efficient operation, together
When, the power source of gas engine heat pump system proposed by the present invention is non-renewable energy, and has recycled engine by residual neat recovering system
Waste heat, meet the demand of national energy-saving policy.
