Abstract
An experimental jet-pump refrigeration system was designed and constructed to assess the performance of R245fa (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 coefficient of performance (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 R245fa as their working fluid, for high temperature applications, such air conditioning.
