Sorption heat pump

A method for controlling a sorption heat pump comprising

• feeding fuel to a burner via a feed line comprising a fuel valve;
• heating a generator containing a heat transfer fluid with the burner and thereby pressurizing the heat transfer fluid;
• condensing the vapors produced by the heating in a condenser;
• throttling the condensed heat transfer fluid vapors coming from the condenser;
• passing the throttled condensed fluid into an evaporator;
• returning the output fluid from the evaporator via an absorber to the generator;
• exchanging heat between fluid and a circulating medium for a thermal use provision in the condenser and absorber;
• controlling an intensive thermodynamic parameter of the fluid in the pressurized section of the sorption heat pump depending on the heat requirements of the thermal use provision;
• joining the generator and the condenser into one single column;
• providing the generator and the condenser in a joint container;
• connecting the condenser by way of a feed pipe and of a return pipe to a thermal use provision;
• disposing the condenser as pipe coil heat exchanger in the dome of the joint container;
• providing a condensate collector below the condenser;
• connecting a condensate pipe to the condensate collector;
• connecting a three-way valve to the condensate pipe where the input and one output of the three-way valve effects a condensate feedback and feedback connection which has a return opening into the interior of the casing above the uppermost overflow plate.

• joining the generator and the condenser into one single column;
• providing a rectifying column between generator and condenser;
• feeding via a pipe a solution rich in refrigerant into the generator in the area of the rectifying column;
• providing a shut-off valve and a feed line for the solution rich in refrigerant above each of the overflow plates disposed in the rectifying column;
• coordinating concentration sensors disposed above the overflow plates to a controller;
• providing second concentration sensors in the area of the pipe feeding in the rich solution;
• opening in each case by way of the controller that valve which connects the pipe with that overflow plate, where the concentration of the level in the column corresponds most closely to the concentration of the solution inside of the pipe.
