Résumé

An experimental jet-pump refrigeration system was designed and constructed to assess the performance of R-245fa (1,1,1,3,3-pentafluoropropane) as a suitable refrigerant. The paper describes and evaluates the results of experimental tests over a range of operating conditions. In addition, the effects of primary nozzle geometry on jet-pump performance are reported. Performance maps, useful for practical design and control are also provided. Experimental values of COP between 0.25 and 0.7 were obtained. These results demonstrate that low-grade heat can be used to drive efficient jet-pump refrigeration systems, using R-245fa as their working fluid, for high temperature applications, such air conditioning.
