Overview of automatic air conditioning system
1. The difference between automatic air-conditioning and manual air-conditioning. Automatic air-conditioning system is the basic component of general air-conditioning system. The main difference is that the automatic air conditioning system can maintain the preset indoor temperature. It uses sensors to determine the current temperature, and then the system can adjust the warm and cold air as needed. The system uses the opening and closing of the actuator to adjust the mixed air flow to achieve a suitable temperature in the car, so that the temperature meets the driver's requirements. There are two types of automatic air-conditioning systems: semi-automatic air-conditioning systems and fully-automatic air-conditioning systems. The main difference between the two is whether there is a self-diagnosis function. The semi-automatic air-conditioning system does not provide fault code memory, and the automatic air-conditioning system has a monitoring system and a random access memory for the monitoring system. Store the diagnostic code.
2. The automatic air-conditioning system allows the driver to select the working mode, wind speed and set indoor temperature of the air-conditioning system by operating the buttons on the controller assembly. After the control connector receives the instruction, it controls the corresponding actuator to complete the instruction action.
A general automatic air conditioner is composed of the following components: 1. Controller assembly 2. Actuator 3. Sensor
3. Working principle: When the automatic air-conditioning system is working, according to the driver's preset temperature, the air-conditioning compressor or heating device is automatically turned on to adjust the wind speed of the blower and the internal and external circulation of air. In order to achieve a comfortable indoor temperature. The core component of automatic air-conditioning is the air-conditioning ECU (controller assembly), which receives relevant information of the air-conditioning system, such as indoor and outdoor temperature, evaporator temperature, and system pressure. Based on this information, the action of the air-conditioning actuator is controlled to meet the set temperature in the car.
