What does 'max' mean on the air conditioning?

[Troy]

The 'max' button on the car air conditioning refers to the maximum cooling mode. Below is more information about car air conditioning: 1. Car air conditioning is a very important comfort feature in vehicles, used almost daily during summer and winter. 2. Car air conditioning can both cool and heat. The cooling principle of car air conditioning is quite simple: during cooling, the compressor clutch engages, allowing the engine to drive the compressor. The compressor then continuously compresses the refrigerant and delivers it to the evaporator. Inside the evaporator, the refrigerant expands and absorbs heat, cooling the evaporator. The cooled evaporator then cools the air blown by the blower, allowing the car air conditioning to blow cold air. 3. The refrigerant used in car air conditioning is R134a, which needs to be replaced regularly. Otherwise, the cooling speed may slow down, and the cooling effect may deteriorate. The heating principle of car air conditioning is also simple: during heating, the high-temperature coolant from the engine flows through the heater core, and the air blown by the blower passes through the heater core, allowing the car air conditioning to blow warm air.
