Which button adjusts the temperature of the car air conditioner?

[SanHarrison]

Temperature adjustment buttons are usually marked with a "thermometer" icon or have red and blue color indicators on both sides. Rotating the knob towards the red zone gradually increases the temperature. Below is relevant information: 1. Car Air Conditioning: The car air conditioning system (air conditioning device) is used to regulate and control the temperature, humidity, air cleanliness, and airflow within the vehicle cabin to optimal conditions, providing passengers with a comfortable environment and reducing travel fatigue. It also creates favorable working conditions for the driver, playing a crucial role in ensuring safe driving. 2. Types of Air Conditioning: Based on the driving method, it can be divided into: Independent type (uses a dedicated engine to drive the compressor, offering large cooling capacity and stable operation, but with higher costs, larger size and weight, mostly used in large and medium-sized buses) and Non-independent type (the air conditioning compressor is driven by the car engine, with cooling performance significantly affected by the engine operation, resulting in poorer stability, mostly used in small buses and cars).
