Should You Turn on AC When Using Car Air Conditioning in Summer?

[DiManuel]

In summer, you should turn on the AC when using car air conditioning, as it is the cooling switch for the car's air conditioning system. If you do not press the AC button, the car air conditioning will not cool. However, in winter when using the car air conditioning, there is no need to press the AC button. The car air conditioning is an important comfort feature in vehicles, and it is used almost daily during winter or hot weather. The cooling principle of car air conditioning is relatively simple. After pressing the AC button, the clutch of the air conditioning compressor engages, allowing the engine to drive the compressor. When the compressor operates, it continuously compresses the refrigerant and delivers it to the evaporator. The refrigerant expands and absorbs heat in the evaporator, cooling it. The cooled evaporator then cools the air blown by the blower, allowing the car air conditioning vents to blow cold air.
