Summary

A completely new way of using an ecologically friendly, not flammable and nontoxic working gas for heat pump applications is realized in the Rotation Heat Pump (RHP) by using a Joule process instead of a Rankine Process. Substantiated by a working fluid which is always gaseous, it is possible to obtain a sensible heat transfer at sink and source. The main problem to accomplish an efficient Joule process in heat pumps, the compressing of the gas, is based on a centrifugal potential which allows a compression efficiency of more than 99%. Another major advantage of the Joule process within the RHP is the possibility to change the temperature range from -20 up to 150 °C without affecting the coefficient of performance (COP) considerable. The COP is mainly determined by the temperature spread between sink and source. Latest tests on the first industrial RHP validate the function and possibilities of this new technology.
