How to cool down the steel workshop building?
The cooling treatment of steel workshop building needs the right medicine. First of all, it is necessary to find out the reasons that affect the temperature rise of the steel structure workshop, and pay attention to the treatment of one-sided problems. Then choose the appropriate method to deal with the relatively unnecessary factors, so as to achieve a good indoor environment.
1. Insulation and cooling of steel workshop building.
The steel structure workshop building insulation film can isolate most of the solar radiation and conduction heat, reducing the indoor greenhouse effect. Then greatly reduce the temperature of the factory and improve the environment of the steel structure factory building.
There are two commonly used methods now: covering insulation cotton on the roof of the steel workshop structure. The insulation cotton used on the roof is generally glass wool, with a common thickness of 50mm, 75mm, 100mm and a density of 10kg/m. The equipment is good, the indoor temperature can generally be reduced by 5-8 ℃, and the construction process is messy. If the old factory building is to be heat-insulated, it is necessary to cancel the original roof, pull up the steel mesh, and lay glass wool on the steel mesh.
Spray high-efficiency heat-insulating reflective paint on roof panels. This coating can be applied to steel structure, metal, concrete, gray wall, wooden structure surface, asbestos tile, plastic, glass fiber reinforced plastic, rubber and other surfaces. The coating thickness is 0.25mm, and the effect is equivalent to that of 10cm-15cm glass wool. It can reflect 99.5% infrared rays, 92.5% visible light, and has a high sound insulation effect of 68%. The uniform sound insulation effect of the steel workshop building is more than 50%. Fire class A, completely non-combustible. Non-toxic and safe, long-lasting and durable, with a service life of more than 15 years, preventing the aging of engineering materials.
2. Ventilation and cooling of steel structure workshop.
Since some machines in the steel structure factory building generate heat and water vapor, if these hot air and water vapor are not discharged in time, they will accumulate in the workshop, and then the temperature rise of the steel workshop structure will affect the environment of the steel structure factory building. The way to deal with these problems is to ensure proper ventilation of the factory and set up a proper ventilation system. The smooth exhaust system equipment will significantly improve the air environment of the steel workshop building and greatly reduce the temperature of the steel structure workshop.
The roof unpowered ventilator is a ventilation device based on the principle of air convection. When the outdoor air conditions are different, air movement occurs and then cleans the indoor exhaust and hot air. The advantage is that it does not require additional electricity and is more environmentally friendly. However, it is highly dependent on the environment and cannot be forced to exhaust. It mainly includes turbo ventilator, strip ventilator (lighting belt ventilation), roof ventilator, etc. Roof forced exhaust fan of steel structure workshop equipment Power fan is a ventilation device driven by electricity. Its exhaust effect is good, and it can adapt to the ventilation of any environment.
3. Forced cooling of steel workshop building.
Forced cooling refers to a machine that uses the principle of water cooling to cool the air and transports the cold air to the room through a strong exhaust fan. It can keep the indoor temperature of the steel workshop structure at a quiet temperature of 26-30℃. Its power consumption is equivalent to 1/8 of the air conditioner. The cost is 1/2 of the air conditioner, and it is a good method for forced cooling of the workshop.
