Experimental Analysis of Alternative Refrigerant as Replacement of Hfc134a
An experimental performance study on VCR system with 100g R600a/R290 refrigerant mixture and 100g R600a (pure isobutene) as drop in replacement of R134a was conducted . continuation running tests were performed under different length of capillary for R600a/R290 & R600a. The result showed that the hydrocarbon mixture (R600a/R290) had highest COP at L=10 feet length capillary by17.35% -23.5% for ...

متن کاملAn Experimental Investigation of Ternary Refrigerant Blends Performance Proposed as Substitutes for CFC-12
In this paper, the performance of various concentrat~ons, of the proposed blends, as alternatives to CFC-12_, are evaluated under different operating conditions from thermal capacity, as well as coefficient of performance point of view. Other cycle characteristics, such as pressure ratio, system pressures, temperatures and compressor power are also discussed. This has been accomplished with the...
متن کاملPerformance Comparison of Domestic Refrigerator using HFC134a and HFC134a/HC Refrigerant Mixture
An experimental performance comparison study on domestic refrigerator system was conducted and compared with HFC134a and M09 (HFC134a and HC blend (containing 55.2%HC600a and 44.8%HC290 by weight)) mixture refrigerant. The domestic refrigerator system was initially designed to operate with HFC134a.Experimental results showed that the refrigeration capacity of the refrigerant M09 mixture system ...
متن کاملTransport Properties of Refrigerant Mixtures: Thermal Conductivity
In the present work, the integral equations method is used to calculate transport properties of polar fluids. For this goal, we use the Stockmayer potential and examine theoretically the thermal conductivity of several refrigerant mixtures such as R125+R134a, R125+R32, R125+R152a, R134a+R32, R152a+R32, R134a+R143a, and R125+R143a. We solve numerically the Ornstein-Zernike (OZ) equation usin...
