SUMMARYThe purpose of this work is the thermodynamic analysis and the performance prediction of R22-E181 absorption water chilling package for standard rating conditions according to ARI 560-2000. The analysis is based on the description of the exact thermodynamic cycle plotting the enthalpy-mass fraction and the temperature-enthalpy charts. The thermodynamic properties of the R22-E181 are given in a new set of equations using extended experimental data from the literature.A step-by-step calculation model was established in order to predict the characteristic points of the thermodynamic cycle of the R22-E181 ARU and to simulate its performance.The influence of the ambient conditions on the operation of the ARU is shown graphically when the saturated condensing temperature ranges from 30 to 458C. Regression analysis is carried out to express the actual coefficient of performance and the cooling load as functions of the condenser temperature and the absorber-condenser temperature difference.According to ARI Standard 560-2000 for an absorption water chilling package, it has been found that the integrated part-load value of the COP ranges from 53 to 60%. When the saturated condensing temperature is 41.18C, the saturated evaporating temperature is 48C and the ABS/COND temperature difference ranges from 6 to 98C. The decrease of the chilled water temperature passing through evaporator is 5.68C.

“…Thus, it is very necessary to explore new working pairs which can overcome the serious problems. Therefore, many researchers have paid lots of attentions on the development of new refrigeranteabsorbent pairs (Eiseman, 1959;Bhaduri and Varma, 1985, 1986, 1988Agarwal and Bapat, 1985;Thieme and Albright, 1961;Wang et al, 2010;Jelinek et al, 1978;Fatuh and Murthy, 1993). Among these refrigerants, HCFC-22 is considered to be the best fluorocarbon refrigerant for use in absorption refrigeration systems by date, but as a result of regulation to phase out hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs) and mixtures of these fluids are being investigated as alternative refrigerants (McLinden et al, 1998;Borde et al, 1995;Tillner et al, 1998;He et al, 2003He et al, , 2005Chen, 2004, 2007).…”

“…The calculation results and the design of refrigeration equipment are affected by the accuracy of VLE data. Bhaduri et al measured the p-T-x data of HCFC-22 combined with absorbents N , N -dimethylacetamide (DMAC), cyclohexanone, diethylene glycol (DEG), aniline, and xylene. Ando et al and Jelinek et al studied the solubility of HCFC-22 in dimethyl ether diethylene glycol (DMEDEG) and N , N -dimethylformamide (DMF), respectively.…”

Fluoroethane (HFC-161) is one of the most promising alternative refrigerants because of its excellent environmental and thermodynamic properties. It was considered as one of the most promising absorption working fluids in the absorption refrigeration. To make a better application of the refrigerant in absorption refrigeration systems, suitable absorbents should be selected for matching HFC-161. Vapor− liquid equilibrium (VLE) data is the key of the chemical engineering simulation and the refrigeration cycle calculation. On the basis of these, the vapor−liquid equilibrium data for the mixture of HFC-161 + dimethyl ether triethylene glycol were obtained at temperatures from 293.15 to 353.15 K by using a recirculation apparatus. The VLE data were then correlated by the Peng−Robinson (PR) equation of state combined with the modified Huron-Vidal first order (MHV1) mixing rule and nonrandom two liquid (NRTL) model. The experimental results had a good consistency with calculated values. Phase behaviors of HFC-161 combined with different absorbents were compared in this paper.
