Abstract

The invention relates to an efficient electric cold and warm air heat exchange system used for a vehicle. The efficient electric cold and warm air heat exchange system comprises a vortex motor compressor, a heat exchanger outside the vehicle, a heat exchanger inside the vehicle and an economizer. An auxiliary suction port is formed in the vortex motor compressor, refrigerating fluid flows out of the heat exchanger outside the vehicle and then is divided into two paths, the refrigerating fluid in the first path is subject to heat exchanging, then is subject to undercooling, enters the heat exchanger inside the vehicle through an electronic expansion valve and finally is sucked through an air suction port of the vortex motor compressor. The refrigerating fluid in the second path enters the economizer through an electronic expansion valve and is changed to be gas after the refrigerating fluid is cooled in the first path and finally enters the vortex motor compressor through the auxiliary suction port. The heat exchange system can effectively solve the problems that under the working condition of low temperature, heating is not sufficient, and exhaust temperature of the compressor is too high.

Description

technical field [0001] The invention relates to the technical field of vehicle air conditioners, more specifically, the invention relates to a high-efficiency vehicle electric cooling and heating air heat exchange system. Background technique [0002] Electric vehicle air conditioners must solve the two major problems of cooling and heating. At present, the more popular solutions in the industry mainly include the following two methods: the first is to use the electric compressor cooling system + PTC heating function, such as the attached figure 1 As shown, under the test conditions of ambient temperature 40°C, vehicle interior temperature 27°C, and relative humidity 50%, when the system is stable, it can obtain 1.8kW cooling capacity with 1kW energy consumption; 1kW of energy consumption only obtains 1kW of heating capacity. The second is the heat pump type electric vehicle air conditioning system, such as the attached figure 2 As shown, under the test conditions of amb...
