Refrigeration using heat
Webrefrigeration is made using heat engine energy to supply input heat.. This can be achieved by vapor absorption system by using waste heat produced from engine. 2. MAIN SECTION 2.1 Refrigeration Refrigeration is the process of removing heat from a body. The removed heat is moved to a place where it does not affect the working system. WebRefrigerant is a chemical compound capable of transitioning from liquid to gas and back again. During the process, its abilities to absorb and transfer heat have been the key to cooling, refrigeration and heat pump systems for many years. Historically, refrigerant has been manufactured using a number of different chemical combinations.
