AIR-CONDITIONING SYSTEM, IN PARTICULAR, FOR SWITCH-GEAR CABINETS Russian patent published in 2006 - IPC F24F5/00 F24F13/22 

FIELD: air conditioning, in particular, for cabinets of switch gears.

SUBSTANCE: the system has a cabinet for switch gears with a cooling device, with the aid of an air blower it is possible to suck in warm air from the cabinet inner cavity for the switch gears and supply it to the evaporator, from which cold air can be directed to the cabinet inner cavity for the switch gears, a condenser is positioned under the evaporator, supplied to which can be the incoming air from the environment, the extension of the lines of cold gears may be constant or varied, switch gears may be constant or varied, the cooling device consists of an upper bearing plate, lower bearing plate and a box-like protective casing of the hood type closing both bearing plates, the air-conditioning system has several evaporators positioned in the plane of air blowing, the condenser is positioned under the evaporators so that the evaporators positioned at a distance from one another by one section or by their front areas are positioned above the condenser, and the condensate fed from the evaporators in the located above the condenser areas drops onto the condenser and evaporates, approximately similar pressure ratios are maintained in the chamber formed by the upper bearing plate and in the chamber formed by the lower bearing plate in connection with the protective casing of the hood type.

EFFECT: enhanced reliability.
