Is the AC in a car for cooling or heating?
1 Answers
ac switch is for cooling. When the vehicle needs cooling, pressing the AC button (the indicator light on the button will illuminate) activates the air conditioning in cooling mode. Adjust the temperature selection switch to the blue section, turn on the blower, and cold air will blow out. The AC is the compressor switch, and the compressor is the heart of the car's air conditioning cooling system, responsible for compressing and transporting refrigerant vapor. Below is relevant information: 1. Too much or too little refrigerant: This is the most common reason for air conditioning not cooling. Refrigerant leakage is the primary cause. When the air conditioning is not cooling, check the refrigerant level through the sight glass on the dryer. If the refrigerant is insufficient, the sight glass will continuously produce bubbles. If the refrigerant is too low, simply add more. Too much refrigerant can also prevent the air conditioning from cooling, as it affects the system's heat dissipation. Observe the sight glass on the dryer; if no bubbles appear during operation or after the compressor stops, it indicates excessive refrigerant. In this case, simply remove some. 2. Dirty condenser: Excessive accumulation of dust, lint, and other debris on the condenser and air filter can hinder the air conditioning system's heat dissipation, which in turn affects cooling performance.
