Siddiqui [1] , Aaftab A. Farooqui [2] , Mazaroddin Sheikh [3] Faizan Momin [4] , Fahim Shaikh [5] Department Of Mechanical Engineering Everest College Of Engineering & Technology Aurangabad - India ABSTRACT This paper gives a review on a working model of Refrigerator cum Air conditioner by combining the two units i.e. domestic Refrigerator and Air-Conditioner into a single unit. This working model refrigerator cum air conditioner is a device that performs both task at same time i.e. cooling refrigeration cabin and room. By this method the energy and cost can be reduced from the cost of individual equipment. In minimum construction, maintenance and running cost, this attempt is quite useful for domestic purpose thus those who cannot afford an Air Conditioner can have the comfort of Air Conditioner. Refrigerator has become a necessity of all households in 21st Century. In all metropolitan cities, environment degradation due to automobile & other factors is on the rise, therefore the requirement of air-conditioner has already been felt. The motivation for the project comes from rising energy demands and hence its cost. As we all know that we are lacking of power resources, so this project will help us in tackling this problem as we are trying to make a personalized cooling system which will run at a very low cost that can be afforded by a common man. Since all energy cost are on a rise, therefore this project is a way forward in realizing the economic as well as environmental demands. On the other hand, the common man can have the comfort of Air conditioner. Keywords :— Domestic Refrigerator, Air conditioner, Affordable, Productivity, Portability, Environment Degradation. I. INTRODUCTION In nature, heat transfer occurs from higher temperature to lower temperature without requiring any external devices. The reverse process cannot occur by itself. The transfer of heat from lower temperature to higher temperature requires special devices called refrigerators. Refrigeration and air conditioning play a very important role in modern human life for cooling and heating requirements. It covers a wide range of applications starting from preservation of perishable food products to the thermal comfort to human beings by means of air conditioning and hence living standards of people. The utilization of refrigerators and air conditioners in homes, hospitals, offices, vehicles and industries provides for thermal comfort in living or working environment and hence plays a very important role in increased industrial production of any country. The increasing demand of energy primarily for refrigeration, air conditioner and Heat Pump applications is around 26–30%, which degrades environment, produces global warming and depletes ozone layer, etc. Therefore, to overcome these aspects, we are making a working model of Refrigerator cum Air conditioner by combining the two systems i.e., Domestic Refrigerator and Air conditioner into a combined system, which performs both task at same time i.e. cooling refrigeration cabin and surroundings such that the running cost becomes negligible and the power consumption will reduce. Because of its minimum construction and running cost, and portability this working model is quite useful for domestic purpose thus those who cannot afford an air conditioner can have the comfort of air conditioner. This is how we are trying to make the environment and a common man comfortable. By this product, a common man could have a sound sleep so that his productivity for the next day increases. II. LITERATURE REVIEW A. Prof. S. K. Gupta The paper reported about the attempt he made to merge Domestic Refrigerator and Air conditioner into a combined system by which the power consumption will reduced, cost and space will be minimum. BECAUSE OF ITS MINIMUM construction, space and cost an ordinary man can afford it easily. After experimentation he conclude that a common man can have comfort of air conditioner at very low running cost or zero cost, which would prepare him for better productivity for the next day. B. M.
