Abstract

The invention discloses a scroll pump with stable exhaust, a scroll compressor and a vehicle-mounted heat pump air-conditioning system. device, the second parallel flow heat exchanger, refrigerant is set in the circulation loop, the outlet of the compressor, the vehicle-mounted four-way reversing valve, the first parallel-flow heat exchanger, the expansion valve, the second parallel-flow heat exchanger, the vehicle-mounted The four-way reversing valve and the inlet of the compressor form a refrigeration mode circuit; the outlet of the compressor, the on-board four-way reversing valve, the second parallel flow heat exchanger, the expansion valve, the first parallel flow heat exchanger, and the on-board four-way heat exchanger Inlets to valves and compressors form a heating mode loop. The heat pump air-conditioning system of the present invention adopts an electric scroll compressor for a heat pump, and a plurality of exhaust holes are added on the pump body to enhance the exhaust stability, and the heat exchanger inside the vehicle can be exchanged with the heat outside the vehicle through a four-way valve. The function of the inverter is interchanged to adapt to the switching between cooling and heating modes.

Description

technical field [0001] The invention relates to the technical field of air-conditioning systems, in particular to a scroll pump with stable exhaust, a scroll compressor and a vehicle-mounted heat pump air-conditioning system. Background technique [0002] Global warming, air pollution, and rising energy costs are becoming more and more serious. As one of the main sources of environmental pollution and energy consumption, automobiles have received more and more attention on energy conservation and emission reduction. Governments and automobile companies in various countries will Energy saving and environmental protection are regarded as the guiding direction for the development of future automobile technology, and energy saving and environmental protection electric vehicles will emerge as the times require. At present, the research and development of electric vehicle air-conditioning technology lags behind the development of vehicle technology itself. At present, domestic el...
