Points for attention in site selection and layout of generator room
The engine room design plan of the generator set manufacturer. Issues to be aware of in the design of emergency diesel generator rooms in civil buildings: including site selection, intake, exhaust vents, flue design and other professional coordination issues.
With the development of society and the improvement of people's living standards, in modern civil buildings, the types and quantity of electrical equipment are increasing. Among these electrical equipment, there are not only fire-fighting equipment such as fire pumps and spray pumps, but also There are life-saving equipment such as living pumps and elevators that need reliable power supply. In order to meet the reliability of the power consumption of these equipments, when the municipal power grid cannot provide two independent power sources, the method of using diesel generator sets as backup power sources in the design is widely adopted. .
Although the diesel burning point is relatively high and the fire risk is relatively small, in the civil building, the diesel generator set is placed in the main body of the building, which is theoretically still dangerous, and then considers the ventilation during the operation of the unit. Problems such as noise and vibration will undoubtedly require us to fully consider and take adequate preventive measures. The specific practices include the following aspects.
Selection and arrangement of the location of the generator house:
Taking into account the air intake, exhaust, smoke exhaust, etc. of the generator house, according to the requirements of the "Electrical Design Code for Civil Buildings", the diesel generator room should be arranged on the first floor, but usually the first floor of civil buildings such as large public buildings and commercial buildings. It is a golden zone, and the first floor will bring some noise to the surrounding environment. Therefore, according to the regulations, when there is difficulty, it can also be arranged in the basement. Because the access to the basement is not easy, the natural ventilation conditions are bad, which brings a design to the engine room. A series of unfavorable factors, pay attention to the design
First, the following points should be noted when selecting the site:
1. It should not be located in a room without external walls, creating conditions for the hot air duct and the exhaust pipe to be discharged outside;
2. Try to avoid the main entrance, façade and other parts of the building to avoid the impact of exhaust and smoke exhaustion;
3. Pay attention to the impact of noise on the environment;
4. It should not be placed directly under the toilet, bathroom or other places where water is often accumulated;
5. It should be close to the substation of the building, which is convenient for wiring, reducing the loss of electric energy and facilitating management;
6. Should not be close to the anti-vibration room;
7. There is an oil storage room in the machine room.
Second, the layout of the machine room
1. The diesel generator room shall be separated from other parts by a partition wall with a fire resistance of not less than 2.00 hours and a floor of 1.50 hours;
2. The machine room should have two entrances and exits, one of which should meet the requirements of the handling unit. The door should be fireproof and soundproofed and should be opened outwards.
3. The wall and ceiling of the machine room are used as sound absorbers to absorb part of the sound energy and reduce the reverberation caused by sound wave reflection;
4. The equipment layout in the equipment room should meet the requirements of the "Electrical Design Code for Civil Buildings", and strive to be compact, safe and easy to operate and maintain.
