Abstract: A method of improving the thermoconductivity of heat exchange for an air conditioning or refrigeration system, comprising introducing a concentrate into the system which comprises introducing a concentrate into the compressor of the system, the concentrate comprising an amine phosphate deactivator, such as a yellow metal deactivator, a chloronated paraffin, a calcium salt of dialkyl aromatic sulfonic acid, polyalpha-olefin, a nonylated phenylamine derivative, an ashless disperant, carboxylic acid esters, fatty acid derivatives, triazole carbamates and a barium or calcium sulfonate, and an additive having the composition, used in the concentrate, and a compressor driven system utilizing the novel additive.
