What is the typical power consumption of a car air conditioning system?
1 Answers
Generally, a car air conditioning system requires 8 to 10 kilowatts of engine power. Here are some relevant details: Regarding air conditioning power: The power consumption of the air conditioning system is mainly composed of the power consumed by the air conditioning compressor and the blower. Moreover, the power consumption varies continuously when the air conditioning is on. This is because the power of the air conditioning compressor is determined by three factors: the pressure difference between the compressor's inlet and outlet, the compressor's displacement, and the current rotational speed. These three factors have a multiplicative relationship. If it is a mechanical compressor, the power comes from the engine. Its rotational speed is related to the engine, and the power also varies with the engine speed. The power consumed by the blower is related to its own rotational speed. For example, different fan speed settings result in different power consumption by the blower.
