FIELD: gas industry.
SUBSTANCE: invention relates to air cooling devices of gas and can be used for cooling of gas after compression at main gas pipelines compressor stations. Gas air-cooling apparatus control system comprises temperature setting unit, first controller, frequency converter, asynchronous motors, fans, heat exchanger and temperature sensor. Output of the first regulator is connected to the input of the frequency converter, the output of the frequency converter is connected to asynchronous electric motors kinematically connected to the fans influencing the air flow to the heat exchanger. System is equipped with second regulator, made in form of proportional-differential controller, second regulator input is connected to temperature sensor output, its output is connected to the second regulator first input, temperature setting unit output is connected to the first regulator first input. First regulator is in form of an integral regulator.
EFFECT: invention is aimed at improvement of dynamic characteristics and simplification of system tuning.
