Air cycle refrigeration is one of the earliest methods used for cooling. The key features of this method is that, the refrigerant air remain gaseous state throughout the refrigeration cycle. Based on the operation, the air refrigeration system can be classified into 1. Open air refrigeration cycle 2. Closed refrigeration cycle
I would like to begin this course with brief history of refrigeration, and the specific objectives of this particular lesson are to define refrigeration and air conditioning. Then introduce the historical aspects of natural refrigeration methods and artificial refrigeration methods. See Full PDF.
