<p>Vaporisers are influenced by a fluid environmental heat carrier, and fluidisers are located with pref. parallel actions in the path of a fluid medium being heated, in pumps for a heating installation, which also has a regulator. The high-pressure part of one pump coolant circuit has two heat transmitters (30,54) alternatively switched into it, one being in heat contact with the medium, and the other in cascade relationship to the second pump vaporiser, and in heat contact with its vaporised coolant. The regulator.</p> |
