Paper deals with modelling and experimentation on single-phase vapour ejector in application to air-conditioning systems. Particularly very interesting is the case with a low temperature motive heat source which may be applied to solar air-conditioning units. The testing rig, selected test results obtained with refrigerant R-123 as well as numerical modelling results of vapour ejector have been presented in the paper showing reasonably good agreement.
