How to cool down the single storey steel structure workshop?
The cooling treatment of the single storey steel structure workshop needs the right medicine. First of all, it is necessary to find out the factors that affect the temperature rise of the steel structure factory building, pay attention to the treatment of one-sided problems, and then choose an appropriate method to deal with the relatively unnecessary factors, so as to achieve a good indoor environment.
1. Insulation and cooling of single layer steel structure workshop
The steel workshop building structure 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.
There are two commonly used methods: covering the roof with thermal insulation cotton on the roof of the single layer steel structure workshop. 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. Steel structure can be applied to metal, concrete, gray wall, wood 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 the effect of 10cm-15cm glass wool. It can reflect 99.5% of infrared rays, 92.5% of 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%.
2. Ventilation and cooling of the single storey steel structure workshop
Since some machines in the steel structure workshop 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 structure factory building will affect the environment of the single storey steel structure workshop. The way to deal with these issues is to ensure fair ventilation on the factory floor and to have a proper ventilation system. Equitable exhaust system equipment will significantly improve the air environment of the steel workshop building structure and greatly reduce the temperature of the single storey steel structure workshop.
Equipment 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. The products mainly include 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 single storey steel structure workshop
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 structure factory building at a quiet temperature of 26-30℃. Its power consumption is equivalent to 1/8 of the air conditioner, and the cost is 1/2 of the air conditioner. It is a good method for forced cooling of the workshop.
