Vortex pump with stable exhaust function, vortex-compressor and vehicle-mounted heat pump air-conditioning system

Abstract

The invention discloses a vortex pump with a stable exhaust function, a vortex-compressor and a vehicle-mounted heat pump air-conditioning system. The heat pump air-conditioning system comprises a compressor, a vehicle-mounted four-way reversing valve, a first parallel flow heat exchanger and a second parallel flow heat exchanger which form a circulation loop, the circulation loop is internally provided with a refrigerating fluid, an outlet of the compressor, the vehicle-mounted four-way reversing valve, the first parallel flow heat exchanger, an expansion valve, the second parallel flow heatexchanger, the vehicle-mounted four-way reversing valve and an inlet of the compressor form a refrigerating mode loop; the outlet of the compressor, the vehicle-mounted four-way reversing valve, the second parallel flow heat exchanger, the expansion valve, the first parallel flow heat exchanger, the vehicle-mounted four-way reversing valve and the inlet of the compressor form a heating mode loop.The heat pump air-conditioning system has the advantages that the electric vortex-compressor for a heat pump is adopted, multiple exhaust holes are formed additionally to enhance the exhaust stability, and the functions of an in-vehicle heat exchanger and ex-vehicle heat exchanger can be interchanged through four-way valves to adapt to switching between a refrigerating mode and a heating mode.

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...
