FIELD: refrigeration engineering.
SUBSTANCE: lubricating composition comprises synthetic lubricant containing polyol ester and/or polyethylene glycol and amphiphilic anti-sedimentation component (preferably 0.001 to 5%) selected from group including: dialkyl sufosuccinate and salts thereof, fluoroaliphatic polymeric ester, aromatic sulfonic acid and salts thereof, comb-shaped grafted methyl methacrylate/mathacrylic acid/methoxypolyethylene oxide copolymer, and acrylic graft copolymer in combination with fluorohydrocarbon-containing refrigerant. Refrigeration system comprises compressor, condenser, surge chamber, and evaporator forming closed circuit wherein fluorohydrocarbon refrigerant circulates.
EFFECT: reduced velocity of clogging of system by unwonted sediments in bottle-neck zones.
