Development and market trend of gas engine heat pumps in Japan.

Author(s) : SAKATA S.

Summary

Since 1985, gas-engine heat pumps (GHPs) have been manufactured for commercial air conditioning market as thermally driven heat pumps. GHPs can recover the heat of the exhaust gas from the engine which makes them more energy efficient than electric conditioners during the heating operation. Recently, new specification units named "multi-type heat pumps for use in office buildings" have been introduced, similar to the electric driven heat pumps in commercial use. For future development, it is necessary to consider reduction of the nitrogen oxide emission, lengthening the period of regular inspection and the introduction of alternative refrigerants instead of R22.
