An experimental solar ejector refrigerant system using HFC134 as working fluid is designed and constructed to study the critical performance in this paper。 The relationship between the ejector critical condenser temperature and the system working condition has been proposed。 The experimental results show that the COP and ejector entrainment ratio keep almost constant firstly, and then reduce dramatically when it arrives the critical point at the given generator temperature with the condensation temperature increasing。 The critical condensation temperatures increase with the generator temperatures when evaporator temperature remains constant; and the critical condensation temperatures increase with increasing evaporator temperature when generator temperature remains constant。
