An electrical control room is a room or building where electrical equipment for various purposes operates. Only specially trained employees come here and work here. There are technical standards for the equipment of these premises, including the requirements for the ventilation of electrical control rooms.
Ventilation rates for electrical control rooms
A supply and exhaust ventilation system with forced or natural air movement is installed in the control rooms. The ventilation requirements for the control room do not include heating or air filtration.
Although the technical staff does not work in the control rooms all the time, special conditions are necessary for the smooth operation of the equipment, including the exchange of air.
The design is carried out on the basis of SNiP ventilation in the switchboard SN 31-110-2003. It is also important to take into account the number and power of electrical equipment that generates heat. In any frost, the temperature inside the room should be from +5 to +20 degrees. Relative humidity should be kept between 30 and 60 percent.
As a rule, natural methods are used to ventilate electrical control rooms. But sometimes you have to resort to coercive methods if the natural ones do not provide the set parameters.
Safety standards
An indispensable condition in accordance with the ventilation standards of the switchboard is the installation of fire dampers on the ventilation ducts.
If the fire alarm is triggered, the kapana will stop the ventilation system. In addition, the outputs of the ventilation ducts must be painted with non-combustible light paint or tiled with light tiles.
If, in addition to the electrical control room, there are halls or workshops in the building that require the same temperature indicators, they can be combined with a common ventilation system.
According to the requirements of SNiP ventilation in the electrical room, it is necessary to provide air exchange 3 - 5 times per hour.
Doors in switchboards
The ventilation standards for the switchboard provide for special door designs. So, at the bottom and at the top of the doors, it is necessary to equip gratings for the movement of air masses. Doors must be metal. The grill on the doors is not fitted with a blind or a door, it must always be open.
If the openings are closed, air flow through the doors will stop, the equipment may overheat, catch fire or melt. You can order a special door for the switchboard to order. The main purpose of the ventilation of electrical control rooms is to regulate the temperature required for the operation of equipment.
