[Technical Column] Issue 12: The Refrigeration Cycle of Car Air Conditioning and Its Challenges

Introducing the principles of the refrigeration cycle and effective methods for energy-saving in car air conditioning!

In this column, I will discuss the composition of the car air conditioning refrigeration cycle and its challenges. The principle of cooling is based on a closed circuit known as the refrigeration cycle, which consists of two heat exchangers, a compressor that compresses the refrigerant, and an expansion valve that serves as a depressurization device. Recently, with the demand for improved fuel efficiency in vehicles, there has been a growing need for energy-saving measures in car air conditioning systems, leading to various considerations. The most effective method is to enhance the performance of the condenser. By improving its performance, the high pressure decreases, which reduces the compression work of the compressor, thereby leading to a reduction in the input energy of the compressor. Additionally, it is also necessary to improve the efficiency of the compressor itself. *For more details on the column, you can view it through the related links.
