How much fuel does a car's air conditioning consume in one hour?

[StZachary]

Household cars consume approximately 1-3 liters of fuel per hour when running the air conditioning. Below is a related explanation: Compression process: The compressor draws in low-temperature, low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature, high-pressure gas before discharging it from the compressor. Heat dissipation: The high-temperature, high-pressure superheated refrigerant gas enters the condenser, where it condenses into a liquid due to the reduction in pressure and temperature, releasing a significant amount of heat. Heat absorption: The mist-like refrigerant liquid enters the evaporator. Since the boiling point of the refrigerant is much lower than the temperature inside the evaporator, the refrigerant liquid evaporates into a gas. During the evaporation process, it absorbs a large amount of surrounding heat, and then the low-temperature, low-pressure refrigerant vapor re-enters the compressor. This process repeats continuously to achieve the goal of lowering the temperature of the air around the evaporator.
