ABSTRACT:
A space is cooled by gasifying or vaporizing a first, preferably liquid substance in a first container located in said space. The gas or vapor thus formed is conducted into a second container located outside the space and containing a second substance generating a lower gas pressure than said first substance at the same temperature, preferably by being chemically bound thereby. Said gas or vapor is absorbed by the second substance, which shall possess the quality of forming a porous, substantially rigid body in its container after heating or regeneration in vacuum. The second substance is comprised of sodium sulphide, at least as its major ingredient.
Additionally an apparatus for carrying out this method comprises a first container which contains a gasifiable or vaporizable substance and is located in a space to be cooled, at least one second container which is located outside this space, and conduits which comprise a shut off valve and connect said first container with said second container which contains a second substance, which generates a lower gas pressure than said first substance at the same temperature and has the ability of absorbing gas emitted or generated by said first substance. The second substance is comprised of sodium sulphide, at least as its major ingredient.
