With the arrival of winter, the temperature gradually decreases, and many car owners will turn on the heating and air conditioning when driving. However, while turning on the heating and air conditioning, many people will struggle with whether they need to turn on the AC (air conditioning compressor). So, when driving in winter, should you turn on the air conditioner to turn on the a-c?This article will unravel this mystery for you. a cFirst of all, we need to understand the role of a c (air conditioning compressor). In the summer, a c is used to cool down and reduce the temperature inside the car. In winter, the A C is mainly used for heating, compressing the air and transferring heat through the heat exchanger, thereby increasing the temperature in the car. 
Whether a c needs to be turned onWhether or not you need to turn on a c to blow the air conditioner when driving in winter mainly depends on the temperature and humidity inside the car. 1.When the temperature inside the car is low and the air is dry, it is recommended to turn on a c. Because in this environment, the heating effect of the warm air conditioner will be affected, and turning on a c can effectively improve the heating effect, while maintaining the humidity of the air in the car and avoiding the discomfort caused by drying. 2.When the temperature inside the car is high and the humidity is also high, it is not recommended to open a c. Because in this environment, turning on A C will not only reduce the heating effect, but also increase fuel consumption. Therefore, in this case, it is possible to turn off a c and rely on the heating function of the warm air conditioner to raise the temperature in the car. 
Why do many people not prescribe A CA lot of people don't like to turn on a c when driving in the winter, mainly because of the following reasons:1.Fuel consumption: Many car owners believe that turning on A C will increase fuel consumption, which is a big burden for some economy car owners. Therefore, in order to save fuel consumption, many car owners choose to only turn on the heating and air conditioning when driving in winter. 2.Comfort: Some car owners believe that turning on AC will reduce the humidity in the car, making the air dry, which is easy to cause uncomfortable symptoms such as dry mouth. Therefore, in order to maintain humidity in the car, they chose not to turn on the AC. 3.Environmental protection: Some car owners with strong environmental awareness believe that turning on AC will emit a large amount of greenhouse gases such as carbon dioxide, which has a negative impact on the environment. Therefore, in order to protect the environment, they chose not to prescribe a c. 
To sum up, whether you need to turn on the air conditioner when driving in winter mainly depends on the temperature and humidity in the car. In the case of low temperature and high humidity in the car, it is recommended to turn on a c to improve the heating effect and maintain the humidity in the carIn the case of high temperature and humidity in the car, it is not recommended to turn on a c to avoid reducing the heating effect and increasing fuel consumption. Therefore, car owners can choose whether to turn on AC or not according to the actual situation to get the best driving experience. At the same time, we should also note that the use of A C is closely related to environmental protection and energy saving, so we should use A C reasonably to improve driving comfort under the premise of protecting the environment.
