HEAT PUMPS WITH HYDROCARBONS AS REFRIGERANTS FOR SMALL RESIDENTIAL BUILDINGS


The paper reports about operational experiences with a heat pump example and propane as
refrigerant. It is to conclude: heat pumps with HCs as refrigerant could be a good chance for reduction
of environmental stress. The handling of them is not so difficult if the special properties of HCs are
considered. Therefore the widen application is no technical problem but a safety problem which could
be solved only by law. Manufacturer of components and of heat pumps must not take the unreasonable
risk furthermore
