What is the general temperature for using car air conditioning in winter?

[LaDerek]

In winter, the car air conditioning temperature is generally set between 18 degrees Celsius and 25 degrees Celsius. Below are detailed introductions to specific components of the car air conditioning system: 1. Air conditioning pressure sensor: Usually installed after the dryer, it is used to detect the hydraulic pressure of liquid refrigerant flowing through the expansion valve. Three wires: detect high pressure and low pressure. In case of refrigerant leakage and compressor oil loss after a car collision, to prevent compressor damage due to lack of oil, once low pressure is detected, the compressor power is quickly cut off. When high pressure is detected, the compressor power needs to be reduced to avoid wasteful energy consumption. 2. Air conditioning temperature sensor: Usually installed inside the temperature sensing package, it is the evaporator temperature sensor. When the temperature drops to a certain level, the compressor needs to be shut down to prevent frosting and eventual ice blockage from further cooling. 3. Air conditioning compressor relay: Usually installed on the compressor, it is used to control the compressor's start, stop, and power switching functions.
