[Technical Column] Issue 12: The Refrigeration Cycle of Car Air Conditioners 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 refrigeration cycle, which is a closed circuit consisting of two heat exchangers, a compressor that compresses the refrigerant, and an expansion valve that serves as a depressurization device. Recently, with the increasing demand for improved fuel efficiency in vehicles, there has been a growing need for energy-saving 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, improving the efficiency of the compressor itself is also necessary. *For more detailed information on this column, please refer to the related links.
