Abstract (en)
[origin: US4580720A] For operating a heat pump installation with water as the refrigerant, a vacuum pump is employed as the compressor. If a liquid ring pump is used, its dissipation heat is fed into the heating loop. To this end, the heat output side of the heat exchanger associated with the loop of the sealing liquid is connected to the primary or secondary heat carrier loop of the heat consumer associated with the refrigerant loop.
