Comparative Study on Waste Heat Recovery System from Domestic Refrigerator

Heat is energy, so energy saving is one of the key matters from view point of use of refrigerants and for the protection of global environment. This waste heat will affect the environmental conditions because as heat in the environment will increases it will cause global warming and also not good for our ozone layer too. So it is necessary that a significant and concrete effort should be made for conserving energy through waste heat recovery too. 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 experiment has shown that such a system is technically feasible and economically viable. This system rejected less heat to the environment so it is safer in environmental aspects.
