Output (English): The invented cooling liquid intended generally for heat exchangers, particularly for cooling systems of internal combustion engines, gas compressors, refrigerating systems, heat exchangers of system for utilization of solar energy contains 80 to 86.99 percent by weight of glycerol, 2.0 to 5.0 percent by weight of at least two admixtures being selected from the group comprising corrosion inhibitors, stabilizing additives, pH adjusting additives, improving additives and additives preventing unintentional confusion with other liquids. The cooling liquid preferably contains 1.5 to 3.5 percent by weight of corrosion inhibitor represented by alkali, preferably sodium salt of mono- and/or dicarboxylic acids containing 6 to 12 carbon atoms, and it further contains a pH adjusting additive that is represented by alkali, preferably sodium salt of glyceryl boric acid in an amount of 0.5 to 2 percent by weight or alkali hydrogencarbonate, preferably potassium hydrogencarbonate in an amount of 0.1 to 1.0 percent by weight, and the balance to 100 percent by weight being water. The cooling liquid is free of any glycols, in non-toxic and non-corrosive. It can be diluted with demineralized, service or potable water in volume ratios 1 part of the cooling liquid to 0.01 to 10 parts of water.
