Definitions

the invention relates to a sorption heat pump which can be operated in boiler mode, with a hot water or hot gas-cooled absorber, a cooker and a device with which the flow of the working fluid emerging from the cooker can be influenced as a function of measured variables.
absorption and absorption heat pumps result in operating states in which heat pump operation is no longer possible.
bivalent heat pumps are known (DE-OS 27 48 415), in which a bypass line is provided which bypasses the evaporator and the absorber, through which the working medium is conducted as a heating medium for pure boiler operation when the ambient temperature is a certain value falls below.
This known device requires several regulator-controlled valves to switch from one to the other operation.
the invention has for its object to solve the problem of switching operation in a technically simple manner in a sorption heat pump of the type mentioned.
the many control valves provided in the known device are eliminated. With just one additional line and a pressure valve, it is possible to switch to heat pump or boiler operation. With two-stage expeller heating outputs, the rectification column downstream of the cooker can be optimized to the lower burner output stage (heat pump stage) (smaller dimensions). In addition, by utilizing the high enthalpy difference of the water-containing steam in boiler operation, high boiler heating outputs can be transferred. The solvent pump can therefore be dimensioned relatively cheaply.
the poor solution 16 sucked out of the cooker 1 flows via a solution heat exchanger 4 and a throttle 5 also to the absorber 8.
the rich solution present at the absorber outlet is finally fed back to the rectification column 2 by a solvent pump 9 via the dephlegmator cooling 3 and the solution heat exchanger 4.
a steam line is provided which opens into the boiler room 1 and the rectification column 2 and the dephlegmator 3 immediately to the absorber 8 leads.
a constant pressure valve 6 that can be adjusted to a certain upper condenser pressure
the steam line 17 is automatically released for switching over to boiler operation when the pressure in the condenser 13 exceeds a predetermined level.
the stove heating output is directly coupled into the heating network.
the heating medium 14 is heated to a higher temperature than in heat pump operation.
the rest of the heat pump circuit remains unchanged, i.e. no lines are switched off.
the withdrawal of steam via the steam line 17 naturally reduces the flow of working fluid in the rest of the heat pump circuit.
connection for boiler operation described above can be used accordingly in a resorption heat pump and in general in sorption heat pumps with other working medium circuits and working material pairs.
