Does Car Air Conditioning Consume More Fuel?
1 Answers
Car air conditioning consumes more fuel when cooling in summer because activating the cooling function starts the compressor, which increases the engine load. If the idle speed is too low, the air conditioning will automatically adjust the engine speed to meet its power demand. Therefore, running the air conditioning at low idle speed does not save fuel, and using the cooling function in car air conditioning increases fuel consumption. The following is a detailed introduction to car air conditioning: 1. Introduction 1: The heating principle of car air conditioning is very simple. After turning on the heating function, the high-temperature coolant from the engine flows through the heater core. The air blown by the blower passes through the heater core, allowing the air vents to blow warm air. 2. Introduction 2: The cooling principle of car air conditioning is also straightforward. Pressing the AC button engages the compressor clutch, causing the engine to drive the compressor. The compressor continuously compresses the refrigerant and sends it to the evaporator. 3. Introduction 3: When the refrigerant expands in the evaporator, it absorbs heat, cooling the evaporator. The cooled evaporator then cools the air blown by the blower, allowing the air vents to blow cold air. Almost all cars are equipped with air conditioning, which enhances driving comfort.
