Abstract
The environmental impacts like global warming and ozone depletion have become a challenge for R & AC Industry. Even though the refrigerant R134a is better in performance, it is categorized under hydrofluorocarbon which has more GWP and poor heat transfer rates. So, the refrigerant is likely to be phased out; therefore, there is a need to go for alternative refrigerant. The other refrigerants may be hydrocarbons and mixture of hydrocarbons. Hydrocarbons are called natural refrigerants because they occur in the earth’s material cycle, as a by-product of natural gas production, or in oil refineries. They are non-toxic as well as ozone-friendly. Also in domestic refrigerator, condenser is the heat exchanger which condenses the refrigerant to liquid phase by losing latent heat. It exchanges the heat with atmosphere through natural convection. The heat transfer coefficient for the natural circulating air is less than the forced circulating air. In order to increase heat transfer rate, forced convection is used. In this work, a cabin is modeled by using aluminum sheet. Performance of 220L capacity refrigerator equipped with forced convection apparatus working on hydrocarbons will be analyzed.
