Résumé

Energy required to drive a mechanical pump in heat driven systems in most of the cases is a few percent of the overall energy balance of the system and in most cases is of the order of magnitude 1%. The most important problem is a special difficulty to select of a commercially available liquid pump for the heat driven cycle. Mechanical liquid pump liquid is the only element of the refrigeration system that consumes electric power. It is desirable that the whole system would be fully heat driven one, without consumption of electric power to drive.
Two-phase vapour-liquid injectors may be thought as required alternative. They are using vapour that is generated already in the system; operates as pre-heater of liquid phase supplied to the vapour generator that additionally improve the system efficiency; and have no moving parts. Paper deals with experimental investigation of operation of the fully passive system with two-phase vapour-liquid injector as a liquid pump in refrigeration systems. Presented results are the first ones for the system operating with low-GWP refrigerant under conditions of fully passive operation.
