Résumé

A new separate heat-pipe refrigerator and heat pump is suggested based on the general three temperature thermal jet refrigerator and heat pump cycle. Sub-cooled hot water or another appropriate liquid heated by low grade heat sources forms the hot end and another heat pipe containing evaporator and condenser ends, adiabatic section of two-phase ejector and throttling tube is as the cold end of the separate heat pipe system. Performance relations for the thermal jet refrigerator and heat pump of such system is analysed and a method of thermodynamic performance analysis is recommended. Primary prediction shows the feasibility of such a heat-pipe system for cold and warm water supply.
