Does Car Air Conditioning Heating Consume More Fuel?

[DelRiver]

Car air conditioning heating does not consume more fuel because it has a simple structure without additional equipment. The heating function of the air conditioning system utilizes the heat generated by the engine operation, which is then circulated through the coolant to dissipate heat and brought into the cabin. There is a small radiator inside the dashboard, and at this point, turning on the blower will provide warm air. Additional Information: 1. During the cold start phase of the engine, when the engine coolant temperature has not yet reached the optimal operating range, the fuel system increases fuel injection to raise the idle speed, accelerating engine operation to bring the coolant temperature up to the proper range for optimal performance. 2. If the heating system is turned on at this stage, the insufficient coolant temperature will not achieve the desired warm air effect. The vehicle's system will further increase fuel injection to raise the idle speed and assist in warming up the engine. Therefore, turning on the heater during a cold start or driving at low speeds for an extended period after starting the engine is actually a fuel-intensive practice.
