The reason why the air conditioner sometimes blows cold and sometimes not is to check whether the air conditioning expansion valve is malfunctioning. Here is an introduction to car air conditioning: 1. Introduction: Car air conditioning refers to the air conditioning device installed in the car, which can cool, heat, ventilate and purify the air in the compartment, providing a comfortable riding environment for passengers, reducing the driver's fatigue and improving driving safety. 2. Structure: It generally includes refrigeration devices, heating devices and ventilation devices. This combined device makes full use of the limited space inside the car, with a simple structure and easy operation, and is an internationally popular modern car air conditioning system. 3. Arrangement: The arrangement of different types of air conditioning systems varies. Currently, the most widely used in cars is the integrated heating and cooling air conditioning system.
