Does Using Natural Air Without AC Consume More Fuel?

[NolanLynn]

Using cold air without AC does not consume more fuel, but it also does not save fuel. Here are the reasons: 1. AC Switch: Air conditioning cooling must go through four working processes: compression, heat release, throttling, and heat absorption. The AC switch is the control switch for turning the air conditioning compressor on and off. The compressor's operation is a necessary condition for heat exchange inside the car. Only when the compressor is working can it draw in the low-temperature, low-pressure gaseous refrigerant from the evaporator and turn it into a high-temperature, high-pressure gas to flow to the condenser, maintaining the circulation of the refrigeration system. This is the compression process in the air conditioning system. 2. Why Not Using AC Does Not Consume More Fuel: Using cold air without AC means the compressor does not need to work. If the compressor is not working, there is no concern about its power consumption or the temperature difference between the inside and outside of the car. Therefore, it cannot be said to consume more fuel.
