Vehicle-mounted air conditioner controller and adjustment method thereof

Abstract

The invention discloses a vehicle-mounted air conditioner controller. The vehicle-mounted air conditioner controller is characterized by comprising a carrier and a mainboard, wherein the mainboard comprises a starting signal detection unit, an inner blower control unit, an inner blower temperature detection unit, a compressor control unit, a compressor temperature detection unit, an outer blower control unit, an MCU (Micro Control Unit) master control unit and indication and display unit. The output end of the starting signal detection unit is connected to the MCU master control unit; the inner blower control unit is connected to the MCU master control unit by virtue of the inner blower temperature detection unit; the compressor control unit is connected to the MCU master control unit by virtue of the compressor temperature detection unit; the control input end of the compressor control unit receives the MCU master control unit; the MCU master control unit is respectively in output control connection to the outer blower control unit and the indication and display unit. According to the vehicle-mounted air conditioner controller disclosed by the invention, the dual temperature detection devices are adopted, so that variable frequency output of the compressor can be realized, the operating current of the compressor is reduced, the rotation speed of the outer blower can be intelligently regulated, the power consumption of the outer blower is reduced, and the service life is prolonged.

Description

【Technical field】 [0001] The invention relates to a vehicle air conditioner and a parking air conditioner, in particular to a controller for controlling the vehicle air conditioner. 【Background technique】 [0002] Whether it is a household air-conditioning system or a vehicle air-conditioning system, the refrigeration principle is basically the same, but there are differences in subtle user requirements and compressor selection. After starting the air-conditioning system, the compressor works to drive the refrigerant to circulate in the sealed air-conditioning system. The compressor compresses the gaseous refrigerant into a high-temperature and high-pressure refrigerant gas and then discharges it from the compressor, and flows into the condenser through the pipeline. Internal heat dissipation, cooling, condensed into normal temperature and high pressure liquid refrigerant flows out. [0003] The normal temperature and high pressure liquid refrigerant enters the dry liquid r...

AI Technical Summary

Problems solved by technology

[0007] 1) The current parking air conditioner controls the compressor in a fixed-frequency output mode, which cannot effectively save power according to the actual ambient temperature inside the car

[0008] 2) The current parking air conditioner uses the switch control method to control the external fan. Due to the different temperature of the external environment and the length of working time of the parking air conditioner, the air conditioner has different requirements for the heat dissipation of the condenser (external fan). If Using the switch mode to control the fan will keep the fan running at full load, consuming a lot of power
