Abstract

An externally controlled variable-displacement compressor air-conditioning system, which includes an air-conditioning controller, which also includes a pressure regulating valve that controls the compression ratio of the compressor according to the change signal of the pressure in the air-conditioning pipeline; The control module of the pressure regulating valve of the displacement compressor, the control module includes a single-chip microcomputer, a pulse width modulation power amplification module, an overcurrent protection module that can realize overcurrent protection, and a current detection module that can detect the output current. Beneficial effects: the air conditioning system using the variable displacement compressor can automatically adjust the power output according to the set temperature, saving a lot of energy.

Description

technical field [0001] The invention relates to an automotive electronic air-conditioning system and an air-conditioning device in the technical field of automotive electronics, in particular to an externally controlled variable-displacement compressor air-conditioning controller device. Background technique [0002] The car air conditioning controller is the core component of the car air conditioning system. It collects: evaporator temperature sensor, outside temperature sensor, inside temperature sensor, sunlight intensity sensor, water tank temperature sensor signal, output control such as: temperature damper actuator, mode damper actuator, circulation damper actuator, blower, Compressors are used to realize multiple functions such as cooling, heating, ventilation, air purification, humidification and dehumidification. [0003] At present, the air-conditioning system using a fixed-displacement compressor is generally controlled by collecting the temperature signal of the...
