The car air conditioner has two functions:
1. Heating. Many people think that turning on the air conditioner will increase fuel consumption. In fact, this is a wrong view. Turning on the air conditioner does not increase fuel consumption. It has a lot to do with the working mode of the space. For example, turning on the heating will not increase fuel consumption, but you can use the car engine. The heat generated can achieve the effect of exhaust gas utilization. The cooling effect of car heating is different from air conditioning. The reason for heating is that the circulating water of the car engine generates heat, which is then blown into the car through a blower. If it is not used, it will be wasted. Turning on the heating will not increase Fuel consumption.
2. Refrigeration is different from heating. The compressor of the automobile air-conditioning system needs to work when it is running. The engine provides the power for the compressor. The automobile engine needs to generate power from automobile fuel. On the basis of normal operation, it needs to add more force. , It will definitely lead to an increase in fuel consumption. What is the difference between the fuel consumption of a car with and without air conditioning? There is no accurate statement about how much fuel consumption will increase when the air conditioner is turned on. The increase in fuel consumption is related to other factors such as displacement and vehicle speed. Under normal circumstances, turning on the air conditioner will increase fuel consumption by about 10% on the original basis.
The relationship between automobile air conditioning and fuel consumption
First of all, in terms of displacement, when driving on a normal road, the fuel consumption increased by turning on the air conditioner is less than 1L; if the displacement is less than 2.4 liters, the fuel consumption will increase by more than 1L; if you encounter rugged roads, the fuel consumption will increase even more. The reason for the increase in fuel consumption will be less, because the large displacement is more powerful, and it is easier to drive on many road sections, while the small displacement is difficult to start, and the air-conditioning compressor also accounts for a part of the force, resulting in increased fuel consumption.
The increase in fuel consumption when the air conditioner is turned on is not only related to displacement, speed, road surface, but also to various environments such as temperature and humidity. The test results are released and tested under different temperatures and humidity. It is found that the higher the temperature and humidity, the higher the fuel consumption The more you increase, for example, if you turn on an air conditioner at 20°C, fuel consumption will increase by 10%-20%, and if you turn on an air conditioner at 40°C, fuel consumption will increase by more than 30%.
