Abstract: The invention relates to an absorption refrigerating machine and a process for the operation thereof. It can be used as a household cooling appliance, for example as the last link in the cold chain, or for the cooling of medicine or as a refrigerating set of an air-conditioning system, and use in a stand-alone variant without an electrical energy connection is possible. The absorption refrigerating machine has a condenser, an evaporator and an absorber, and a refrigerant-absorbent mixture can be circulated through all three. There is also at least one solar collector for heating to above the refrigerant boiling point and a refrigerant storage unit connected to the condenser. High-pressurized liquid refrigerant is held in the refrigerant storage unit, and an absorbent storage unit and a desorbent storage unit are connected to the absorber.
