Abstract

The invention relates to a compact sorption cooling unit, comprising at least one adsorber/desorber unit ( 1 ) having a heat exchanger and sorption material, at least one condenser heat exchanger ( 5 ), and at least one evaporator heat exchanger ( 6 ), wherein these building blocks are located in a common, vacuum-tight metal outer housing, and having connection and coupling elements and pipe ducts for the hydraulic interconnection and operation of the unit. The invention provides a sandwich structure, wherein the at least one adsorber/desorber unit ( 1 ) is located in an inner or partial inner housing. The condenser heat exchanger ( 5 ) and the evaporator heat exchanger ( 6 ) are disposed at a distance from each other, and the inner housing having the adsorber/desorber unit ( 1 ) is provided in the intermediate space thereof. The separating surfaces ( 2 ) of the inner housing directed toward the condenser heat exchanger ( 5 ) and toward the evaporator heat exchanger ( 6 ) receive steam valves ( 8, 9 ). Further, a heat insulating layer ( 7 ), or a heat insulating plate, is disposed in the region between the inner housing and the evaporator heat exchanger ( 6 ).
