Do You Need to Turn on AC in Winter?

[Fernando]

If the windshield fogs up severely in winter, you can turn on the AC. The AC is the cooling switch of the car's air conditioning system, and it is not necessary to turn it on in other situations. The car's air conditioning is an important comfort feature that can provide both cooling and heating. During winter and summer, the car's air conditioning is used almost every day. When the car's air conditioning is in cooling mode, the compressor clutch engages, and the engine drives the compressor to operate. While running, the compressor 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's air conditioning vents to blow cold air.
