Evaluation of a Refrigerant R410A as Substitute for R22 in Window Air-conditioner
CFCs have been phased out, except for essential users, and HCFCs are to be eliminated by 2020, because of their ozone depletion potential. This generates a need for the investigation of zero ozone depletion potential (ODP) refrigerants or refrigerant blends. R410A is among newer brand of refrigerant blends, with zero ODP. The biggest difference to R22 is the pressure levels generated which are ...
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...
متن کاملCycle Performance and Heat Transfer Characteristics of a Heat Pump Using R22/R142b Refrigerant Mixtures
A heat pump system is constructed tO evaluate the performance and the heat transfer characteristics. Mixtures of R22/Rl42b are adopted in the heat pump. The heat transfer in the evaporator and the overall perfomance arc measured and analyzed in terms of the compositions and the flow rate of the refrigerants. The evaporator consists of counter~currem concentric circular tubes. Possibility of cap...
