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.

Description

TECHNICAL FIELD[0001]The present invention relates to an absorption refrigerating apparatus and, in particular, to an apparatus that can be miniaturized and can be also mounted on a mover such as an automobile or the like.BACKGROUND ART[0002]In recent years, chlorofluorocarbon used as a refrigerant of an apparatus such as an air conditioner or a refrigerating machine has been replaced with a natural medium such as ammonia, carbon dioxide, carbon hydride, water or the like in view of problems of ozone layer depletion, global warming, and the like.[0003]Particularly an apparatus using water as a refrigerant has advantages that the water is low in cost, the water hardly affects the human body and the environment even if it leaks out, the water is easily processed when disposed, latent heat of evaporation of the water is large, and the viscosity of the water is relatively low. On the other hand, the apparatus has disadvantages that it is forced to be significantly large in size per unit...

AI Technical Summary

Benefits of technology

[0026]According to the present invention, the absorption refrigerating apparatus can be mounted on an automobile or the like because it can be miniaturized while the resistance against vibration thereof can be improved.

[0027]Furthermore, exhaust heat of an engine can be used as an energy for car air-conditioning. Therefore, the energy can be effectively made use of.

Problems solved by technology

On the other hand, the apparatus has disadvantages that it is forced to be significantly large in size per unit capability when designed as a practical machine, because the specific volume of steam in an operating temperature zone is great, resulting in an increase in manufacturing cost and limiting installation places.

Therefore, due to the above reason, combined with the difficulty in miniaturizing the whole apparatus, the mounting of the apparatus on a mover such as an automobile or the like has not been realized (see Patent document 1, for example).
