With the evolution of modern transportation, the performance of car air conditioning systems is crucial for enhancing driving experience and passenger comfort. This article will discuss the working principles of air conditioning systems in both traditional and new energy vehicles, and how high-quality radiator fans from Changzhou Yoonshan can provide solutions to optimize your car's air conditioning system.
Heat exchange refers to the process of transferring heat from a high-temperature area to a low-temperature area. Vaporization (the transition of a substance from a gaseous to a liquid state) releases heat, while condensation (the transition from a liquid to a gaseous state) absorbs heat. These processes are the foundation of car air conditioning cooling.
Compression: The compressor compresses the low-pressure, low-temperature refrigerant gas from the evaporator into a high-pressure, high-temperature gas and sends it to the condenser.
Condensation: In the condenser, the high-pressure, high-temperature gaseous refrigerant releases heat and condenses into a liquid.
Expansion: Passing through the expansion valve, the pressure and temperature of the liquid refrigerant drop sharply, preparing to enter the evaporator to absorb heat.
Evaporation: Inside the evaporator, the low-pressure, low-temperature liquid refrigerant absorbs heat from the surrounding air, vaporizes into a gas, thus cooling the air.
New energy vehicles use an electric compressor instead of a traditional engine-driven compressor, with the remaining process similar to that of traditional cars, which is the four basic steps of compression, condensation, expansion, and evaporation, to achieve the cooling of the air inside the vehicle.
Traditional cars use the residual heat from the engine's cooling system to heat the air in the passenger compartment. Specifically, the hot water from the engine's radiator flows through pipes into a small heater core (heat exchanger) inside the cabin, and the blower fan blows cold air over the heat exchanger surface, absorbing heat and turning it into warm air that is sent into the cabin.
New energy vehicles usually come with an electric heater, which directly heats the coolant. The heated coolant is then pumped into the heating core, and the blower fan guides the air flowing through the heating core, absorbing heat and turning it into warm air that is sent into the cabin. This method does not rely on the heat generated by the engine.
The car ventilation system is responsible for controlling the direction and pattern of air movement, ensuring good air circulation inside the car. Drivers can choose different air delivery modes through buttons on the control panel, such as face, dual, foot, mixed, and defrost modes, to adapt to different driving conditions and personal preferences.
