PURPOSE: To reduce the corrosiveness of a system and to improve the corrosiveness against materials by absorbing ammonia with the mixture of ammonium thiocyanate and water of the quantity which is just enough to form aqueous solution, and constituting the reaction system carrying out a removing evaporation of ammonia.
CONSTITUTION: The mixture of ammonium thiocyanate and the water of the quantity which is just enough to form aqueous solution of ammonium thiocyanate is prepared, and ammonia is absorbed and dissolved in this mixture and the chemical heat accumulating and increasing system is constituted with the reaction system of removing evaporation. As far the practical quantity of water used to ammonium thiocyanate, when 100pts.wt. of ammonium thiocyanate is added with 83pts.wt. of water, the solid crystal of ammonium thiocyanate is not deposited at least by 0°C. By the system like this, the corrosiveness to the construction materials of the device is extremely improved.
