Abstract

Objective: Nowadays, the refrigeration system is commonly used in most places viz. bakery shops, hotels and other food processing industries, where food items are refrigerated to preserve and, subsequently heated before consumption. In order to eliminate the dual energy consumption devices separately our idea is to do heating and cooling with the single refrigeration unit. Methods/Findings: The idea is to improve the recovery of the waste heat generated in the refrigeration unit. The heat is generally dumped to the atmosphere through the condenser. This heat is utilized to maintain the chamber situated at the topmost of the refrigerator unit as hot chamber. Application: The waste heat that recovered will be an energy saving smart approach and also implies reduction in the green-house gas emission to the environment.
