Brief Introduction
The principle of the chemical refrigerant is based on the principle of heat adsorbent when the matter dissolve, a lot of heat will be taken away during the course of dissolution, the temperature of solution will fall down sharply (below the zero degree). The hot air exchange the heat with refrigerant liquid while passing through the heat exchange pipe, and then the temperature become low.
The factor of solubility must be considered when the refrigerant dissolves in water, the lower the temperature is, the lower solubility is, so water refresh is needed if the refrigerant is used constantly.
The chemical refrigerant can be an assistant cooling method application for rescue capsule and refuge chamber, it can be effective supplied for the refrigerant and cooling. And the refrigerant need vacuum packing.
Usage method
Put the chemical refrigerant into the unsaturated water, then the temperature of aqueous solution fall down quickly, and then lay the pipe which filled the hot air into the aqueous solution, then the air will be cool down. Water refresh is needed when the aqueous solution saturate.
