Heat is energy, so energy saving is one of the key matters from view point of fuel consumption
and for the protection of global environment. So it is necessary that a significant and concrete effort should be
made for conserving energy through waste heat recovery too. The main objective of this paper is to study
“Waste Heat recovery system for domestic refrigerator”. An attempt has been made to utilize waste heat from
condenser of refrigerator. This heat can be used for number of domestic and industrial purposes. In minimum
constructional, maintenance and running cost, this system is much useful for domestic purpose. It is valuable
alternative approach to improve overall efficiency and reuse the waste heat. The study has shown that such a
system is technically feasible and economically viable.
