Why does the car lose power when the air conditioning is on?
1 Answers
When the air conditioning is turned on, the compressor starts, and the engine needs to drive the compressor, which inevitably consumes power, equivalent to a reduction in the car's driving force, making the car seem sluggish. This is quite normal. Introduction to Car Air Conditioning: Car air conditioning consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components, designed to regulate the temperature and humidity inside the car, providing a comfortable environment for the driver. Working Principle of Air Conditioning: When the compressor operates, it draws in low-temperature, low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant increase, and it is sent to the condenser. Inside the condenser, the high-temperature, high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser, causing it to liquefy and turn into a liquid. The liquid refrigerant flows through the throttle device, where its temperature and pressure decrease, and it enters the evaporator. Inside the evaporator, the low-temperature, low-pressure liquid refrigerant absorbs heat from the car's interior air passing through the evaporator and evaporates, turning into a gas. The gas is then drawn back into the compressor to start the next cycle.
