Problems solved by technology

[0006] In this absorption refrigeration device F', in its structure, when vibration is applied to the device, the water W located in the evaporator 1' is mixed with the aqueous solution D of the hygroscopic agent located in the absorber 2', or the water W located in the absorber 2' is removed. The possibility of the moisture absorbent aqueous solution D in the regenerator 3' being mixed with the water W in the condenser 4' and the difficulty of reducing the size of the entire device make it impossible to mount it on a mobile body such as a vehicle. (For example, refer to Patent Document 1)

Abstract

Intended is to develop a novel absorption-type freezing unit, which can realize a size reduction and which can be mounted on a mover such as an automobile. The absorption-type freezing unit is characterized in that a semi-permeable membrane is interposed between a coolant positioned in an evaporator and an aqueous solution of a moisture absorbent positioned in an absorber and / or between an aqueoussolution of a moisture absorbent positioned in a reproducer and a coolant positioned in a condenser. Even in case vibrations are applied to the freezing unit, the movement of steam from the evaporator to the absorber and the movement of steam from the reproducer to the condenser are not blocked, while avoiding the mixing between the coolant positioned in the evaporator and the aqueous solution ofthe moisture absorbent positioned in the absorber and between the dehydrated aqueous solution of the moisture absorbent positioned in the reproducer and the water positioned in the condenser. Therefore, the freezing unit can be mounted on the mover such as the automobile.

Description

technical field [0001] The present invention relates to an absorption refrigerating apparatus, and more particularly, to an apparatus that can be mounted on a moving body such as a vehicle while being miniaturized. Background technique [0002] In recent years, Freon, which is used as a refrigerant for air conditioners and refrigerators, has been replaced with natural media such as ammonia, carbon dioxide, hydrocarbons, and water in view of the destruction of the ozone layer and the problem of global warming. [0003] Among them, when water is used as the refrigerant, it has the following advantages: low cost, little impact on the human body or the surroundings even if exposed, easy disposal at the time of disposal, large latent heat of evaporation, and relatively low viscosity. On the other hand, since the specific volume of the steam in the operating temperature range is large, if it is tried to be used as a practical device, the size of the device per unit capacity has to...
