A residential-sized (25KW) absorption heat pump has been developed using organic absorption pairs. Several different absorption pairs were examined duing the course of the program. The final choice was R123a (CClF/sub 2/CHClF) as the refrigerant and ETFE (ethyltetrahydrofurfurylether) as the absorbent. This pair was found to have good overall physical properties and performance equal to present commercial pairs. Based on thermodynamic analysis and actual performance tests, the R123a/ETFE pair will give a projected heating COP of 1.50 with a condensing flue system. The program has demonstrated the feasibility of the organic pairs in general. Combined operational experience of over 36,000 hours on these types of system has been reached with a maximum of 13,000 hours on any single unit. The thermal stability of the absorption fluids was monitored during these tests and was found to be quite acceptable. A new solution pump design was developed for use with the organic pairs. Tests on this pump have achieved over 50,000 hours of continuous operation with animal wear.
