Fridge system in basic working fridge running by because of the refrigerant circulating inside the cooling coil to change state from a liquid into a gaseous state process, called evaporation it cools down the surrounding area covered inside the close system. This basic principle gives us to safe food storage as well as medicine etc. For this deep view for Refrigeration Cooling process feel free to contact homepe service engineer in indore. We are here to help you to give basic knowledge over the deep freezer internal working concept to understand better. the freezer is specially design in a way that the formation of cool air can be smoothly flow inside the deep freezer compartment by the help of air duct inside in it. thus it works on the CFC free refrigerant circulate in inside the cooling cabinet. fridge system in basic working for the freezer cooling coil fan are design as aerodynamically to give more effective cooling effort to the products like medicines, blood samples, food storage items, green vegetables etc. now a day’s the latest technology is focusing on the high efficient cooling performance of the deep freezer this can be already achieving the lowest temperature of deep freezer is nearly -50 degree centigrade to -60 degree centigrade in the cooling cabinet of freezer due which the stored product can be easily freeze in few hours usually it takes 20 to 24 hours to complete whole cooling process. deep freezer has many types according to the working and higher feature. if deep freezer has to used in a place where the product are very sensitive in normal temperature and quick results needs to achieve then two different types of compressor has to fit.
