シリカゲル/無機塩水溶液系ケミカル冷凍装置の熱特性 Thermal Characteristics of Chemical Refrigerating Apparatus using Silica-Gel/Inorganic-Salt-Solution Pair
This report deals with chemical refrigerating apparatus using silica-gel / inorganic-salt-solution pair. Experiments are conducted by changing concentration of inorganic-salt solution and adsorbent / refrigerant pair. The following results are obtained. <br>(1) The temperature of refrigerant in evaporator is lowered as decrease of inorganic-salt-solution concentration. (2) The available salt-concentration range as refrigerant are gained by supercooling in restricted temperature range lower than solidification temperature of solution. (3)Difference of minimum temperature among cooled refrigerants are little in low concentration region. (4)In concentration lower than about10wt%, refrigerants supercool and solidify suddenly. Accordingly these salt-solutions are not available in these region as refrigerants.
