Temperature Regulation: It is responsible for blowing cold air from the air conditioning evaporator or hot air from the heater core into the vehicle cabin, adjusting the interior temperature to create a comfortable environment for passengers. Air Circulation: It manages the in-cabin air circulation. Through recirculation (internal) or fresh air (external) modes, it keeps the air fresh by introducing new air and expelling exhaust gases. Defogging Function: During rainy seasons or wet weather with high humidity, vehicle windows tend to fog up. By activating the air conditioner and selecting the air supply mode, the blower directs airflow toward the windows. The condenser then removes moisture and fog, ensuring clear visibility. Noise Control: During design and manufacturing, measures are taken to reduce operational noise, such as optimizing the impeller design, using sound-dampening materials, and rational component layout, to ensure a quiet driving and riding experience.
