Vehicle air conditioning system and control method

Abstract

The present invention relates to a vehicle air-conditioning system, including an air-conditioning unit and a temperature adjustment system, the temperature adjustment system includes a plurality of temperature sensors in the vehicle, and the plurality of temperature sensors in the vehicle are configured to collect temperatures in different areas of the vehicle; data processing connected to the temperature sensor in the car, and weighted average the collected temperature to obtain a weighted average; the controller connected to the air conditioning unit, and the temperature setting module connected to the controller to set the working temperature of the air conditioning unit; The controller is connected with the data processor, and controls the operation of the air conditioning unit according to the weighted average value and the set temperature, and when the weighted average value is greater than the set temperature, the controller controls the air conditioner set to operate in a cooling mode. The present invention also relates to a control method of the above vehicle air conditioning system. The invention can detect the temperature of different regions in the car, and calculate the weighted mean value by matching different weight coefficients, thereby effectively controlling the operation of the air conditioning unit.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a vehicle air conditioner system and a control method. Background technique [0002] The air conditioning control system of existing vehicles can generally automatically control the operation mode of the air conditioner according to the difference between the set temperature and the detected temperature. If the detected temperature is higher than the set temperature, the cooling mode will be operated, and the detected temperature will be equal to or lower than the set temperature, then the ventilation will be operated. mode; for rail vehicles, multiple air conditioners should be installed in the same train, and the separate control of each air conditioner is not only cumbersome but also not conducive to unified deployment. The solar radiation may lead to high temperature inside the car. When the air conditioner is running in cooling mode, it is easy to cause frost on the evaporator unit, low...

[0002] The air conditioning control system of existing vehicles can generally automatically control the operation mode of the air conditioner according to the difference between the set temperature and the detected temperature. If the detected temperature is higher than the set temperature, the cooling mode will be operated, and the detected temperature will be equal to or lower than the set temperature, then the ventilation will be operated. mode; for rail vehicles, multiple air conditioners should be installed in the same train, and the separate control of each air conditioner is not only cumbersome but also not conducive to unified deployment. The solar radiation may lead to high temperature inside the car. When the air conditioner is running in cooling mode, it is easy to cause frost on the evaporator unit, low pressure failure of the refrigeration system, and liquid refrigerant flowing into the compressor to dilute the compressor lubricating oil, etc., which will affect the efficiency of the air conditioner.
