Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the air-conditioning compressor in the prior art cannot limit the flow of refrigerant inflow during use, resulting in excessive refrigerant inflow during the operation of the air-conditioning compressor, exceeding its operating capacity. The maximum load causes the compressor to work continuously, which will reduce the working life of the compressor in the long run. A control system for the air conditioner compressor of electric vehicles is proposed.

Abstract

The invention belongs to the technical field of air-conditioning compressors and particularly relates to a control system for an air-conditioning compressor of an electric automobile. For the problemthat during the use of the existing air-conditioning compressor, the flow of a refrigerant cannot be limited, causing influence on the working life of the compressor as in the working process of the air-conditioning compressor, too many refrigerants flow in and the maximum load for working of the air-conditioning compressor is exceeded, a scheme as follows is provided: the control system comprisesan AC switch, a PLC, a compressor, a condenser, a throttling expansion valve, an evaporator, an engine and a cooling fan, which are installed on an automobile, and the PLC is respectively electrically connected with the AC switch, the compressor, the condenser, the throttling expansion valve, the evaporator, the engine and the cooling fan. According to the control system in the invention, cycle control of refrigeration and heating of the automobile can be realized through the cooperation of the compressor with a plurality of electronic devices; and meanwhile, the inflow volume of the refrigerant that works for the compressor can be controlled.

Description

technical field [0001] The invention relates to the technical field of air conditioner compressors, in particular to an electric vehicle air conditioner compressor control system. Background technique [0002] The air conditioner compressor plays the role of compressing and driving refrigerant in the air conditioner refrigerant circuit. The air conditioner compressor is generally installed in the outdoor unit. The air conditioner compressor extracts the refrigerant from the low-pressure area, compresses it, and then sends it to the high-pressure area for cooling and condensation. The heat is released into the air through the heat sink, and the refrigerant also changes from gaseous to liquid, and the pressure increases. The working circuit of the air conditioner compressor is divided into evaporation zone (low pressure zone) and condensation zone (high pressure zone). The indoor unit and outdoor unit of the air conditioner belong to the low-voltage or high-pressure area res...
