Abstract
The ejector cooling system (ECS) is suitable for solar cooling application due to its simple design and low cost. An ECS using a multi-function generator (ECS/MFG) as a thermal pumping device without rotating machines for refrigerant circulation has been designed and tested. The experiment of an ECS/MFG operating at full-cycle while using R141b has shown that the COPo can reach 0.225 and cooling capacity of 0.75 kW at generator temperature 90 °C, condenser temperature 37 °C, and evaporator temperature 8.5 °C. The present study also redesigned the ejector for working fluid R365mfc in order to replace R141b. This study has shown that R365mfc can replace R141b as the working fluid of ECS/MFG at no payoff of system performance as long as the ejector design is optimized. © 2008 Elsevier Ltd.
