Today, the editor introduces to you the relevant car knowledge about car air-conditioning controllers. Summer is coming. Many people know that it is impossible to have no air conditioner. However, in summer, many drivers invent their car’s air conditioner and suddenly the air conditioner is not cooling. So what can car owners do on a hot day? Every summer, they often drive People will feel that the car’s air conditioner is not cooling anymore. Let me introduce the car air-conditioning controller to everyone below.

Automotive air conditioning controller: composition

Modern air conditioning systems are composed of refrigeration systems, heating systems, ventilation and air purification devices and control systems.

An automobile air-conditioning controller belongs to a control device of automobile air-conditioning equipment. Adjust the car air-conditioning system, with cooling, ventilation, and defrosting functions. All equipment is firmly installed, the control device and the operating mechanism are flexible, and the operation is free, and the performance is safe and reliable.

The automobile air conditioning system is a device that realizes cooling, heating, ventilation and air purification of the air in the cabin. It can provide passengers with a comfortable riding environment, reduce the fatigue strength of the driver, and improve driving safety. The air-conditioning device has become one of the signs to measure the completeness of the car's functions.

Car air conditioner controller: Type

1. According to the driving method, it is divided into independent type (a dedicated engine-driven compressor, large cooling capacity, stable work, but high cost, large volume and weight, mostly used in large and medium-sized passenger cars) and non-independent (air-conditioning compressor) Driven by the automobile engine, the refrigeration performance is greatly affected by the engine's work, and the stability is poor. It is mostly used in small passenger cars and cars).

2. According to the air-conditioning performance, it is divided into: single-function type (installing and operating separately the refrigeration, heating, and ventilation systems, without interfering with each other, mostly used in large passenger cars and trucks) and integrated cooling and heating (refrigeration, heating, ventilation) The blower and air duct are shared and controlled on the same control panel. When working, it can be divided into a combined type where the cold and warm air work separately and a mixed temperature regulation type where the cold and warm air can work at the same time. Cars mostly use a mixed temperature regulation type).

According to the control mode, it is divided into manual type (toggle the function keys on the control panel to control temperature, wind speed, and wind direction) and electronically controlled pneumatic adjustment (using the vacuum control mechanism, when the air-conditioning function key is selected, it can be automatically within the predetermined temperature Control temperature and air volume).

3. According to the control method, it is divided into: full-automatic adjustment (using the calculation and comparison circuit to control the work of the adjustment mechanism through the sensor signal and the pre-adjustment signal, and automatically adjust the temperature and air volume) and the full-automatic adjustment controlled by the microcomputer (using the microcomputer as the control center to realize The best control and adjustment of the air environment in the car in all directions and multiple functions).

Car air conditioning controller: layout

Different types of air conditioning systems are arranged differently. At present, the integrated air conditioning system of heating and cooling is widely used in cars. The layout type is to assemble the evaporator, warm air radiator, centrifugal blower, operating mechanism, etc., called the air conditioner assembly.

To sum up the above three points, the combination is the main core content of today, that is, the car air-conditioning controller. After reading the introduction of the editor, have everyone made progress? Okay, today the editor will introduce here first. For more information, please pay more attention to Electric State.
