Nitriding is a case hardening thermo-chemical process used in many applications today. Nowadays, the improvement of ferrous materials performance is a problem of high interest. One of well known wear and corrosion properties improving technique is plasma nitriding, in which elemental nitrogen is introduced to the surface of a metal part for subsequent diffusion into the material. As a result, a compound, “white” layer and a diffusion zone are formed at the surface. A literature research was done in order to study the nitriding mechanism and different nitriding methods used in industry. Energy crisis all over the world compelled us to take necessary steps to reduce energy consumption. 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. By saving energy we balance the demand & supply of electricity. So it is necessary that a significant and concrete effort should be made for conserving energy through waste heat recovery system. We have tried to make a cabinet to recover waste heat from condenser from refrigeration system by storing a heat in an insulated cabinet. This heat can be used for number of domestic and industrial purposes. In minimum constructional, maintenance and running cost, this system is more useful for domestic purpose. Basically domestic refrigerator is used to store perishable goods like vegetables, fruits, milk and other beverages etc. All domestic refrigerators use air cooled finned condenser on backside. As domestic refrigerators reject large heat inside room which make us uncomfortable in summer due to temperature rise inside the room. So it is now essential to store this heat inside an insulated cabinet to utilize it for different purposes. Stored heat is used for keeping food hot, heating water which may be used for different purposes. Citation: Prashant .S.
