A gas engine-driven screw air source heat pump cold and hot water unit is characterized in that it is connected by a gas engine drive system, a refrigerant circulation system, an oil circuit circulation system, an economizer energy-saving system, an oil return system, and a gas heat recovery heat recovery unit through pipelines. water system composition. During the heating cycle, the hot water recovered from gas heat flows through the finned heat exchanger (15), heating the air source outside the tube and increasing the evaporation temperature of the refrigerant, thereby realizing the frost-free operation of the air source heat pump. Overcome the stubborn problem of frosting air source heat pump. In the refrigeration cycle, gas heat recovery produces hot water while producing cold water. The beneficial effect is that the energy saving is remarkable, and the economic and social benefits are obvious.
Description
Technical field [0001] The invention relates to an air source heat pump chiller unit for releasing heat to outdoor ambient air or absorbing heat from outdoor ambient air to produce cold water or hot water for air conditioning, in particular to a gas engine driven screw air source heat pump chiller unit. Background technique [0002] The air source heat pump cold and hot water unit consists of a screw refrigeration compressor 1, a four-way reversing valve 8, a cooling / heating mode switching solenoid valve 9, a fan 14, a finned heat exchanger 15, and a liquid supply throttling expansion valve 25 , shell-and-tube heat exchanger 32, etc. are connected by pipelines. When the heat pump is running, the refrigerant absorbs heat from the outdoor low-temperature ambient air in the finned heat exchanger 15, and the screw refrigeration compressor 1 raises the temperature and pressure to produce hot water in the shell-and-tube heat exchanger 32. Then the air is heated up in the air cond...
