Vehicle and air conditioner control circuit thereof

Abstract

The invention discloses an air conditioner control circuit and further discloses a vehicle comprising the air conditioner control circuit. The air conditioner control circuit comprises a condenser loop and a resistive element. When the pressure value in an air conditioner high-pressure loop is not larger than a preset pressure value, the resistive element is connected into the condenser loop, and when the pressure in the air conditioner high-pressure loop is larger than the preset pressure value, the resistive element is retreated from the condenser loop. By applying the air conditioner control circuit, when the pressure value in the air conditioner high-pressure loop is not larger than a preset pressure value, the resistive element is connected into the condenser loop, and a condenser operates at a low speed; and when the environment temperature in a driving cab is over high and the pressure in the high-pressure loop is more than the preset pressure value, the resistive element is retreated from the condenser loop, the condenser operates at a high speed, and refrigerating is achieved accordingly. The failure of impact damage caused to a compressor by compressor frequent starting and stopping is reduced, and the reliability and comfort of a system are improved. The load of the vehicle circuit is reduced, and the service cycles of a vehicle power generator and a storage battery are prolonged.

Description

technical field [0001] The present invention relates to the technical field of vehicle air-conditioning control, more specifically, to an air-conditioning control circuit, and to a vehicle with the air-conditioning control circuit. Background technique [0002] The vehicle air conditioning system mainly relies on the compressor to compress the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, which flows through the condenser to realize the transformation from the high-temperature and high-pressure gaseous refrigerant to the high-temperature and high-pressure liquid refrigerant, and then passes through the drying tank. The liquid refrigerant enters the evaporator through the expansion valve and turns into a low-temperature and low-pressure gaseous refrigerant. During the vaporization process of the liquid refrigerant, it takes away the heat inside the cab and plays a cooling role. [0003] At present, all ligh...
