The cooling treatment of steel structure factory buildings needs to be targeted. Firstly, it is necessary to identify the factors that affect the temperature rise in steel structure factories, pay attention to the treatment of one-sided problems, and then choose appropriate methods to deal with relatively certain factors, in order to achieve a good indoor environment.
1、 Insulation and cooling of
steel structure factory buildings.
The insulation film of steel structure factory buildings can isolate most of the sunlight radiation and conducted heat, reducing indoor greenhouse effect. Then significantly reduce the temperature of the factory and improve the environment of the steel structure factory.
There are two commonly used methods now: covering the roof of a steel structure factory with insulation cotton. The insulation cotton used on the roof is generally glass wool, with commonly used thicknesses of 50mm, 75mm, 100mm, and a density of 10kg/m. Good equipment, indoor temperature can generally be reduced by 5-8 ℃, and the construction process is messy. If insulation renovation is carried out on the old factory building, the original roof needs to be removed, steel wire mesh needs to be pulled up, and glass wool needs to be laid on the steel wire mesh. Spray effective thermal insulation reflective coating on the roof panel. This product has excellent thermal insulation function. Steel structures can be applied to surfaces such as metal, concrete, grey walls, wooden structures, asbestos tiles, plastic, fiberglass, rubber, etc. The coating thickness is 0.25mm, which is equivalent to the effect of 10cm-15cm glass wool. It can reflect 99.5% infrared and 92.5% visible light, with a high sound insulation effect of 68%. The uniform sound insulation effect of steel structure factory buildings is over 50%. Fireproof and non combustible. Long term durability, with a service life exceeding 15 years due to the aging of engineering materials.
2、 Ventilation and cooling of steel structure factory buildings.
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, and the temperature rise of the steel structure factory building will affect the environment of the steel structure factory building. The method to address these issues is to ensure fair ventilation in the factory and install appropriate ventilation systems. Fair exhaust system equipment will significantly improve the air environment of steel structure factories and greatly reduce the temperature of steel structure factories. The equipment roof non powered ventilation fan is a ventilation device based on the principle of air convection. When the outdoor air environment is different, air activity occurs, and then indoor exhaust gas and heat are cleaned. Its advantage is that it does not require additional power, and more. But it has a strong dependence on the environment and cannot be forced to exhaust. The products mainly include turbofans, strip ventilators (daylighting belt ventilation), roof ventilators, etc. The forced exhaust fan on the roof of steel structure factory equipment is a ventilation equipment driven by electricity. It has good exhaust effect and can adapt to ventilation in any environment.
3、 Forced cooling of steel structure factory buildings.
Forced cooling refers to using the principle of water cooling to cool the air, and delivering the cold air to the indoor machine through a forced exhaust fan. It can keep the indoor temperature of the steel structure factory at a quiet temperature of 26-30 ℃. Its power consumption is equivalent to 1/8 of that of an air conditioner. The cost is half of air conditioning, which is a good method for forced cooling in factories.
