Abstract (en)

[origin: EP0188773A2] For the additional operation of a sorption heat pump as boiler heating, the arrangement of a steam line 17 is proposed, which introduces water-containing steam from the boiler 1 of the heat pump directly into the water-cooled absorber 8. An interposed constant pressure control valve 6 automatically opens or closes the steam line 17 when the pressure in the condenser 13 exceeds a given value or falls again respectively. <IMAGE>
