Due to the heat and water vapor generated by some machines in the steel structure factory building, if these hot gases and water vapor are not discharged in time, they will accumulate in the factory building, causing the temperature of the steel structure factory building to rise and affecting the environment of the steel structure factory building.
1、 Ventilation and cooling of
steel structure factory buildings Forced exhaust fan on the roof: Power fan is a type of ventilation equipment driven by electric power. It has good ventilation and can provide ventilation for any situation. Adding air ducts to increase air convection, adding ventilation balls to increase the exchange of roof air and indoor air, and using non powered ventilators is a ventilation equipment developed in the field of atmospheric convection. When there is a distinction between the atmosphere inside and outside the room, a fire atmosphere activity will occur, thereby eliminating indoor exhaust gas and heat.
2、 Forced cooling of steel structure factory buildings
Forced cooling refers to the installation of air coolers on the roof of a factory building. The air coolers use the principle of water cooling to cool the air, and the strong exhaust fans transport the cold air to the indoor machines. It can keep the indoor temperature of the steel structure factory at a comfortable range of 26-30 ℃. Its power consumption is equivalent to 1/8 of that of an air conditioner. The cost is half of that of air conditioning, which is a good method for forced cooling of factories.
3、 Insulation and cooling of steel structure factory building
Steel structure factory insulation can isolate most of the solar radiation and conducted heat, reducing indoor greenhouse effect. Subsequently, the temperature of the factory building was greatly reduced, and the environment of the steel structure factory building was improved.
Setting it up properly may cause the indoor temperature to drop by 5-8 ℃, and the construction process is quite complicated. If insulation renovation is carried out for an old factory building, it is necessary to revoke the original roof, install steel wire mesh, lay glass wool on the steel wire mesh, cover the original roof panel, and then carry out waterproof treatment.
Spray efficient thermal insulation reflective coating on the roof panel. This type of product has excellent thermal insulation efficiency, and may be coated on various surfaces such as metal, concrete, gray walls, wooden structures, asbestos tiles, plastic, fiberglass, rubber, etc. Fireproof grade A, purely non combustible. Non toxic and safe, long-lasting, with a service life of over 15 years. If this method is used, it is convenient to construct, does not damage the original roof, and can prevent the aging of the roof. The maximum temperature difference between the surface of the board after construction and before construction can reach 20 ℃, and the indoor temperature difference can reach 8-10 ℃. The energy consumption of the steel structure plant can be reduced by 30-70%.
