Absorption refrigerating apparatus

Abstract

The present invention is directed to developing a new absorption refrigerating apparatus that can be miniaturized and can be mounted on a mover such as an automobile or the like. The absorption refrigerating apparatus is characterized in that a semi-permeable membrane is interposed between a refrigerant positioned in an evaporator and an aqueous solution of a moisture absorbent positioned in an absorber and/or between an aqueous solution of a moisture absorbent positioned in a regenerator and a refrigerant positioned in a condenser. Even when the apparatus is vibrated, the movement of steam from the evaporator to the absorber and the movement of steam from the regenerator to the condenser are not blocked while avoiding the refrigerant positioned in the evaporator and the aqueous solution of the moisture absorbent positioned in the absorber being mixed with each other and avoiding the dehydrated aqueous solution of the moisture absorbent positioned in the regenerator and water positioned in the condenser being mixed with each other. Therefore, the apparatus can be mounted on the mover such as the automobile or the like.
