Current status of Super Heat Pump Energy Accumulation Systems.

Author(s) : HONJO K., TSUNODA Y., TAKENOUCHI H.

Summary

The paper describes the current status of Japanese large scale energy conservation project entitled as "Super Heat Pump Energy Accumulation Systems". The nine-year super heat pump R&D project was terminated at the end of March 1993. The authors have conducted evaluation tests of high performance electric driven compression heat pumps and chemical heat storage units and on-site evaluation tests for combined system of super heat pump and chemical heat storage unit at a new building. The authors have achieved COP larger than 8 for the electrically driven high performance heat pump of the heating type with the output temperature 85 deg C. With another high performance type, COP 7 was attained for cooling and COP 6 for heating under conditions to meet the Japanese Industrial Standards. Tests of chemical heat storage units have proven that these units were able to reach the target value.
