Outline of Final Research Achievements

This research focused on the ejector heat pump system in which the pressureized refrigerant vapor by solar thermal energy can drive the ejector that can be used instead of the compressor. This research revealed the mathematical model and design method of the solar driven ejector heat pump system.
The detailed performance of the ejector element was clarified with visualization and mathematical analysis. Using the unified analysis theory of the energy system the applicant had focused on for 15 years, the mathematical model of the jector heat pump was constructed and the system performance was revealed. This results contribute the development of new heat pump system that can be driven by low grade heat source and upgrading of the unified analysis theory of the thermal system.
