ENERGY-EFFICIENT COOLING SYSTEM, PRE-TREATMENT OF TURBOMACHINE OIL AND MAINTAINING A COMFORTABLE CLIMATE IN THE HANGAR Russian patent published in 2022 - IPC F16N39/00 F01D25/08 

FIELD: oil cooling.

SUBSTANCE: invention relates to the field of regulation and organization of oil cooling in turbomachines. The effect is achieved due to the fact that the energy-efficient system for cooling, pre-treatment of the oil of the turbomachine and maintaining a comfortable climate in the hangar includes a heat exchanger built into the wall opening of the hangar of the turbomachine, inside which there is a mixing chamber with heat exchange sections, above which are speed-controlled fans, as well as an air temperature sensor in the turbomachine hangar, an air temperature sensor at the inlet to the heat exchange section and an oil temperature sensor at the outlet of the heat exchanger, the mixing chamber is equipped with electrically driven adjustable valves on the outside of the wall and on the inside of the wall, while the heat exchange section is made with and collecting collectors for oil, as well as distributing and collecting collectors for water from an external heating system and with double oil-water channels with a common partition wall, between which there are ribbed inserts with a developed heat exchange surface, this system contains a control processor, which is connected to air and oil temperature sensors, as well as to actuators of fans and valves, the control processor is configured to maintain a given oil temperature at the outlet of the heat exchanger, control air flow temperature at the inlet to the heat exchange section, and when the turbomachine is stopped - maintaining the temperature in the hangar of the turbomachine with the water circulation of the external heating system turned on and the turbomachine stopped, and at the outlet of the fans there are actuators in the form of electrically driven controlled louvre dampers, one of which is connected to the heating/ventilation air ducts of the hangar, and in the wall of the hangar an additional fan with an air valve is placed.

EFFECT: creation of an energy-efficient system that provides cooling and rapid oil heating during the pre-launch preparation of the turbomachine oil system with the function of maintaining a comfortable climate in the hangar by using the heat removed during the oil cooling process to heat the air in the hangar (heating) and automatically maintaining supply ventilation when the turbomachine is running, and also by using the heat of the external coolant of the heating system with automatic maintenance of supply ventilation when the turbomachine is not in operation.
