FIELD: machine building.
SUBSTANCE: proposed method and device are intended for controlled oil cooling in gas turbine units of gas transfer plants and in oil air cooling systems. Cooled oil or oil-air mix temperature is measured for first control system and transmitted via electric line to microprocessor-based controller at variation of impeller rpm of air cooling unit upper fans. Temperature of airflow forced to cooler inlet is measured for second circulation system at varying, if necessary, the impeller rpm of lower fans. Adjustment mechanisms are used to control upper and lower air valves of coolers, valves of circulation channel and outlets valves of air cooler upper and lower fans.
EFFECT: efficient cooling, ruled out thickening in oil channels of heat exchangers at low ambient temperatures.
