Dual use of vapour compression refrigeration system (VCRS)

Abstract

As we all know heat is one of the different forms of energy and to alleviate the problem of protection of global environment saving of energy is very important.Whenever the heat is evolved from any system to the environment, the surrounding temperature increases which nothing but leads to global warming. So in any field the conservation of energy should be done up to the best. So considering the above points we took one of the most usable appliances i.e. water cooler or domestic refrigerator. Of course, condenser is the part which evolves the heat to surrounding atmosphere. So we attempted to recover or utilize the heat which is been wasted from the condenser to surrounding.

Normally water cooler or refrigerator is having air-cooled condenser which we have replaced with water-cooled condenser. We are working on water cooler, so we have arranged two insulated tanks, one for cold water which is usually present in the water cooler and other for hot water which is additional tank we modified. We have dipped condenser tube in additional tank filled with water. Now because of this the heat from condenser which is been getting evolved, rising the temperature of water in the tank which is additionally placed. So this hot water can be used for household purpose replacing geyser. As power consumption of this heat recovery system is very much lesser than geyser although its heating capacity somewhat falls below the capacity of geyser we can substitute the geyser with above system as heating required for household purpose is fulfilled by our system. Here the heating of water will be carried out with the same input power given to cool the water. Hence, energy is been saved up to better extent which leads to the increment of COP ( Co-efficient Of Performance) along with provision of hot water besides cold water. After all this system rejects negligible amount of heat in the surrounding, so it will affect global environment near to nothing.
