A refrigeration system is a combination of components and equipment connected in a sequential order to produce the refrigeration effect. The most common refrigeration system in use today involves the input of work (from a compressor) and uses the Vapor Compression Cycle. This course is an overview of vapor-
The presented paper describes the development of mathematical model suitable for calculating psychometric properties and for simulation of dynamic behaviour of moist air in refrigerated room. Moist air, circulating around refrigerated product within cold chamber, is continuously in direct contact with surface of the goods, chamber walls ...
