Auto Air Conditioning Automatic Temperature Control (ATC), commonly known as constant temperature air conditioning system. Once the target temperature is set, the ATC system automatically controls and adjusts to keep the interior temperature at the set value. The automatic air conditioning system consists of five parts: refrigeration system, heating system, ventilation (air distribution) system, automatic control system and air purification system.
The composition of automatic temperature control system includes temperature sensor, control system ECU, actuator and so on. The temperature sensors include an outside air temperature sensor, an interior air temperature sensor, a sunlight sensor (sunlight intensity sensor) and an evaporator temperature sensor.
