Many motorists see “air conditioning” or a climate control system as mandatory options that should be in the car. However, they forget that the serviceability of expensive units
The air cooling system in the cab helps to prevent the windows from misting up in the cold. This is repeated on all sites and forums. It does indeed dry out the atmosphere, but depending on the outboard temperature, the electronics may prevent the compressor from turning on. The fact is that when it’s winter outside, the refrigerant doesn’t have enough heat from the passing air stream to turn into a gas. And if even a small portion of the liquid freon ends up in an expensive unit, the consequences are fatal. It’s like a water hammer for the engine. Therefore, to maintain the pump’s efficiency, the electronics shut it down, focusing on the readings from the ambient temperature sensors and climate control.
If you look at the manufacturer’s data, Volkswagen assures that its “konde” works at +2 degrees. Below is no more. For BMW, this threshold is plus one degree, while for Nissan it is minus two degrees.
Here you need to study the design of “climate”. For example, the electromagnetic clutch of the compressor due to inactivity in winter can simply turn sour. And the whole system needs lubrication, the role of which is played by freon. Therefore, it is necessary to perform regular preventive maintenance. If it’s too cold outside, turn on a warm box or underground parking. So you heat the car and “cheer up” the air conditioner.
Keep in mind that if the car has climate control, the warning light does not mean that the “cooler” is working. It may well be that it is off and that the windows do not fog up because the fan is working and it is dry in the cabin.
Do not forget about the condensate that forms on the evaporator during the operation of the “climate”. In cold weather, the water freezes and covers it with an ice crust, blocking air circulation. Yes, and it is not possible to drain moisture as in summer. Therefore, even very “advanced” systems in cold weather work as the cheapest. Don’t forget to keep them warm from time to time.
