Abstract

The invention relates to a full-electric vehicle heat pump air-conditioning system based on air compression and circulation. The full-electric vehicle heat pump air-conditioning system comprises a turbine type air compressor, a turbine type air expander, a transmission coupler, a heat regenerator, a vehicle internal air cooler, a vehicle external air cooler, an air mixing box, a direct current fan, a water stop plate with a condensate water disc, a plurality of air-supply air channels, a plurality of air supply openings, a compartment, a vehicle external air inlet, an exhaust opening, a fresh air opening, an exhaust outlet, a three-way reversing valve and a connecting pipe. In comparison with the prior art, based on the semi-open type heat regeneration type air compression and circulation heat pump principle, the air compression and circulation refrigerating and heat pump technology is applied to a full-electric vehicle air-conditioner, and the problem that when a current full-electric vehicle is used in a severe cold region, the power consumption of the air-conditioner is large is solved.

Description

technical field [0001] The invention relates to a vehicle air-conditioning system, in particular to a pure electric vehicle heat pump air-conditioning system based on an air compression cycle. Background technique [0002] Pure electric vehicles (EVs) are more low-carbon and environmentally friendly than traditional internal combustion engine vehicles, but due to the limitation of driving methods, their own power is far smaller than that of traditional vehicles, and the power that can be provided to the air conditioning system is extremely limited. The cruising range of electric vehicles will be greatly reduced when the air conditioner is turned on, and the energy consumption of air conditioners has actually become one of the main obstacles restricting the practical use of new power vehicles. Especially in winter, traditional internal combustion engine vehicles are mainly heated by engine waste heat and thermistor PTC, but pure electric vehicles are driven by motors, and the...
