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

[CamillaMarie]

When using car air conditioning in summer, it is necessary to turn on the AC. The AC button is the cooling switch of the car air conditioning system. If the AC button is not pressed, the car air conditioning will not cool. Below are detailed explanations: 1. Introduction to Car Air Conditioning: Car air conditioning refers to the air conditioning device installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. 2. Cooling Principle of Air Conditioning: 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. Inside the evaporator, the refrigerant expands and absorbs heat, cooling the evaporator. The cooled evaporator then cools the air blown by the blower, enabling the car air conditioning vents to blow cold air.
