How Much Does Using Air Conditioning Increase Fuel Consumption?

[DelElizabeth]

For a car with an average fuel consumption of 10 liters per 100 kilometers, using air conditioning typically increases fuel consumption by approximately 2 liters. Below is additional information regarding air conditioning fuel consumption: 1. Operation of the Cooling System: The automotive air conditioning cooling system consists of a compressor, condenser, receiver-drier, expansion valve, evaporator, and blower fan. These components are connected by copper pipes (or aluminum pipes) and high-pressure rubber hoses to form a sealed system. When the cooling system operates, refrigerant circulates through this sealed system in different states to lower the temperature of the air around the evaporator. 2. Impact of Temperature on Fuel Consumption: Higher temperatures and greater humidity result in higher fuel consumption due to air conditioning use. When temperatures exceed 20 degrees Celsius, fuel consumption increases by approximately 10% to 20%, depending on temperature and humidity levels. If temperatures reach around 40 degrees Celsius, combined with relatively high humidity, fuel consumption can increase by up to 30%.
