Selection of Refrigerant for Air Conditioning System Using MCDM-TOPSIS Approach

The Air conditioning system satisfies the various space conditions required for the comfort and industrial air conditioning. Now days demand for AC system applications are increasing and include the areas of application like apartment buildings, banks, office buildings, industrial plants, schools, restaurants etc. This growing demand for air conditioning system forced manufactures to develop such system which is able to compete in the global market and satisfy the user requirements as well as environmental conditions. A refrigerant plays important role to produce desired cooling effects in AC system as required for providing comfort conditions. Currently numerous refrigerants are available in the market having their own merits and demerits so appropriate selection of refrigerant is very essential. An MCDM-TOPSIS Approach is used to select the appropriate refrigerant including the criteria for selection as Ozone upon Ozone Depletion Potential (ODP), Global Warming Potential (GWP), Latent heat of vaporization (LHVP) and COP (Coefficient of Performance) values.
