Title: Absorption heat pump and process for operation of an absorption heat pump

Abstract: A process for operation of an absorption heat pump in which in a boiling apparatus a solution which contains a refrigerant is heated by a burner in order to expel the refrigerant as refrigerant vapor; the refrigerant vapor is condensed in a condenser by interaction with a heat transfer medium; the refrigerant from the condenser is supplied to a vaporizer and an absorber; the solution which has been depleted of refrigerant from the boiling apparatus is supplied to the absorber; the solution which is rich in refrigerant from the absorber is pumped to a high pressure level and is returned to the boiling apparatus; and the heat transfer medium which has been heated in the condenser is supplied to a consumer and the heat transfer medium which has been cooled by the consumer is returned to the condenser is improved by measuring the outside temperature and the temperature of the heat transfer medium and adjusting the output of the burner depending on the measured temperature values, and by controlling the amount of the refrigerant supplied to the vaporizer, the amount of the solution which has been depleted of refrigerant and which is supplied to the absorber, and the delivery amount of the solution pump.
