ABSORPTION REFRIGERATING MACHINE AND ABSORPTION LIQUID FOR IT

PURPOSE:To suppress a corrosion of a metallic material of an absorption refrigerating machine, by making an aqueous solution of lithium halide which is an absorption liquid include a hydroxide of an alkali metal and an aluminum compound. CONSTITUTION:An aqueous solution including lithium halide (For example, 60weight% LiBr) which is a medium of an absorption, a hydroxide of an alkali metal (For example, LiOH) and an aluminum compound (For example, Al(OH)3) is made an absorption liquid. Or, an aqueous solution including at least one kind or more of oxoacid salts (For example, a nitrate, a molybdate, and a borate, etc.) in the aqueous solution is made an absorption liquid. In this way, a local corrosion which is a cause of a corrosion trouble in the absorption refrigerating machine can be executed, and further, as a suppression of a corrosion speed of a component material can be executed, the absorption refrigerating machine having a very high anti-corrosion performance can be made.
