vehicle air conditioning control system according to the standard air conditioning system is divided into manual and automatic air conditioning system.
1. Manual air conditioning Glossary
only manually to the cold / hot air temperature and air volume adjusting a rough classification, car air-conditioning can not be set to a particular temperature. Toggle function keys on the control panel temperature, wind speed and direction control.
The manual air conditioning advantages simple and clear, easy, almost anything finished fingertips. For the wind speed and direction of arbitrary regulation.
2. Automatic air conditioning Glossary
The automatic air conditioning functions include automatically adjust the interior temperature and humidity, return and supply air mode and an operation mode of automatic control and ventilation control. The electronic control unit according to a driver or passenger display setting button on the control panel by the air conditioning, the air conditioning system automatically run, and in accordance with input signals from various sensors, supply air temperature and air velocity of adjustment in a timely manner, holding the air vehicle environment best.
The advantage of the automatic air conditioning
● The setting operation of the air conditioning system automatically, and according to input signals from the sensors, of the supply air temperature and air velocity timely adjustment of the air vehicle maintain optimum environment.
● the temperature outside the vehicle when the vehicle is closer to the set temperature, the electronic control unit may shorten the working time of the refrigerant compressor, even without starting the compressor, can make vehicle temperature remains set to save energy.
● by placing on a car dashboard air conditioning control panel display, can display the current set temperature, inside temperature, outside temperature, air velocity, air outlet and return air, and the state at any time air conditioning system operation and other information, so that the driver can make timely and full understanding of the work status of the air conditioning system.
● electronic control unit has a self-diagnostic system, early detection of hidden faults in the system when a failure occurs, the system passed the respective fail-safe state, to prevent further expansion of the fault.
