Abstract
Abstract Intermittently operating sorption head and cold storage apparatus having a storage vessel forming a first structural unit. The storage vessel comprises a gas-tight housing and a solid sorption agent which can be heated by a heating medium and is thermally conductively in communication with a heat-eliminating heat-exchange fluid by a first heat-exchanger. The apparatus also has a second heat-exchanger defining at least one of an evaporator and a condenser forming a second structural unit and having a pressure-resistant housing. This unit is thermally conductively in communication by a second heat-exchange device with a heat-exchange fluid capable of eliminating heat in the condensation phase or suppling heat in the evaporation phase. The apparatus also has a pressure-resistant external flow connection for a working medium carried in a closed system between the two structural units. The first structural unit is thermally insulated and the first heat-exchange means has a pressure-resistant conduit embedded in the solid. The second structural unit is thermally insulated and the second heat-exchanger has a pressure-resistant conduit surrounded by the thermal insulator. The flow connection between the storage vessel and the second heat-exchanger is of a low heat conductivity material. Valves for controlling the heat-exchange fluids are also provided.
