FIELD: heating.
SUBSTANCE: invention relates to fan installations of adjustable performance. The control system of air coolers comprises regulators, temperature sensors, fans and heat exchangers in air coolers, as well as the inlet collector and the outlet collector for the cooled medium. The system additionally comprises a temperature sensor of the cooled medium, mounted on the inlet collector, a temperature sensor of the chilled medium, mounted on the outlet collector, and the administrator of the upper level, electrically connected to all the air cooling units of the system, and also with the temperature sensors of the cooled medium and the chilled medium, mounted on the inlet and outlet collectors. The administrator of the upper level is engaged in the system work exclusively in the event of planned or emergency shutdown of one or several air coolers.
EFFECT: invention is aimed at reliable providing system fault tolerance, simplifying its hardware design.
