摘要

Intermittent type cooling apparatus comprising a reserve tank kept relatively cold and completely filled with a solution of a gas in a liquid, particularly an ammoniacal solution, communicating the upper part of this cube, through a conduit from which a part may be connected. subjected to the action of a heating element, with a kettle, in which, when this heating element is in action, the ammonia gas is released from the ammoniacal solution to pass from the top of this kettle to a condenser where liquefies, and at the outlet of which it accumulates in a liquid ammonia tank that feeds a refrigerator where the subsequent evaporation of the liquid ammonia will produce the desired cold, the lower part of the kettle being attached to the lower part of the tank by a second duct, in such a way that, during the operation of the heating element, the ammoniacal solutions coming from the super ior of the tank that have become impoverished in ammonia in the kettle, they return from the kettle to the tank by said second conduit, characterized in that a system of keys is provided to put in communication said deposit of liquid ammonia, or with the upper part of the tank. The boiler, as indicated above, when the heating element is in action, or with a return pipe that opens into the second conduit mentioned, when the heating element is out of action, in which case the pressure drop it is then produced in the boiler, it produces a vaporization of the liquid ammonia in the refrigerator, according to the cold expenditure required by it, and the ammonia thus evaporated comes, by the aforementioned return tube, to be mixed, to be dissolved in them again , with the ammonia solutions, which then circulate from the bottom of the tank to the kettle through the second duct, to return from the kettle to the tank by the first r conduit.
