A/C System Introduction
The automatic air conditioning system is that controller in HVAC control module automatically controls inside air temperature, blower speed, airflow outlet and so forth. Once users set up desired inside air temperature by temperature control selector of HVAC control module (1), controller in HVAC control module detects inside air temperature, outside air temperature, amount of sunlight, and engine coolant temperature by inside air temperature sensor (2), outside air temperature sensor (3), sunload sensor (4), and engine coolant temperature sensor. Then, controller of HVAC control module keeps desired in-car temperature at any time.
