FIELD: chemistry.
SUBSTANCE: compound for precipitate withdrawal from the systems for air-conditioning or air-cooling using vapour compression consists of 1,1,1,2,2,3,4,5,5,5-decafluorine pentane and polyatomic alcohol ester being the product of interreaction of carboxylic acid and at least one polyatomic alcohol selected from neopentyl glycol, glycerine, trimethyl propane and pentaerythrol. The method for precipitate withdrawal or reducing in the air-conditioning or air-cooling system using vapour compression and purification method for the component of the air-conditioning or air-cooling system using vapour compression are described.
EFFECT: improving of the method of air-conditioning or air-cooling systems purification.
