Modern air-conditioning systems consist of refrigeration systems, heating systems, ventilation and air purification devices, and control systems.

Automotive air conditioners are mainly composed of compressors, electronically controlled clutches, condensers, evaporators, expansion valves, liquid storage dryers, pipes, condensation fans, vacuum solenoid valves, idlers and control systems. Automotive air conditioners are divided into high-pressure pipelines and low-pressure pipelines. The high-pressure side includes the compressor output side, high-pressure piping, condenser, liquid storage dryer, and liquid piping; the low-pressure side includes evaporator, accumulator, return line, compressor input side, and compressor oil pool.

Liquid storage dryer-is actually a device that stores refrigerant and absorbs moisture and impurities from the refrigerant. On the one hand, it is equivalent to a car's fuel tank, which replenishes the refrigerant in the space where the refrigerant leaks. On the other hand, it filters out impurities doped in the refrigerant like an air filter. The storage liquid dryer is also filled with a certain amount of silica gel, which plays a role in absorbing water.

Condenser and evaporator-although they are called differently, they have similar structures. They are devices in which a row of curved pipes is covered with metal foil for heat dissipation, so as to realize the heat exchange between the outside air and the substances in the pipes. The condensing of a condenser refers to the cooling of the refrigerant in its pipes to condense from a gaseous state to a liquid state. Its principle is similar to the engine's cooling water tank (the only difference is that the water in the water tank is always liquid), so it is often installed on the front of the car and enjoys the cool breeze from the front with the water tank. In short, where is the cooler where is the condenser so that its heat is condensed? The evaporator is the opposite of the condenser. It is the place where the refrigerant changes from a liquid state to a gaseous state (that is, evaporates) to absorb heat.
