The cooling of the steel structure workshop is a comprehensive topic. To deal with this problem, the steel structure workshop needs the right remedy. First of all, we must find the primary factors that affect the temperature rise of the steel structure workshop, focus on the treatment of one-sided problems, and then select the appropriate method. It will be relatively non-essential elements to deal with, in order to achieve an excellent indoor environment, the highest cost performance.

1. Insulation and cooling of steel structure workshop

The steel structure workshop insulation film can isolate most of the solar radiation and conduction heat, and reduce the indoor greenhouse effect. Then the temperature of the workshop is greatly reduced, and the environment of the steel structure workshop is improved.

Now there are two commonly used methods: adding insulation cotton to the roof of the steel structure factory. Generally, the insulation cotton used on the roof is glass wool. The commonly used thickness is 50mm, 75mm, 100mm, and the density is 10kg/m. The equipment is generally good. The indoor temperature is lowered by 5-8°C, and the construction process is messy. If the old factory building is to be heat-insulated, the original roof needs to be removed, the steel mesh is pulled up, glass wool is laid on the steel mesh, and the steel structure is covered with the original roof panel. Waterproof treatment. Spray high-efficiency heat-insulating reflective paint on roof panels. This product has excellent thermal insulation performance, and the steel structure can be coated on various surfaces such as metal, concrete, gray wall, wood structure surface, asbestos tile, plastic, glass fiber reinforced plastic, rubber and so on. The coating is 0.25mm thick, and its effect is equivalent to that of 10cm-15cm glass wool. It can reflect 99.5% of infrared rays, 92.5% of visible light, the highest sound insulation effect is 68%, and the uniform sound insulation effect of steel structure workshop 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 (for details, please refer to the engineering material file). If this method is used, the construction is convenient, the original roof is not damaged, and the aging of the roof can be prevented. The maximum temperature difference between the plate surface after construction and before construction can reach 20℃, the indoor temperature difference can reach 8-10℃, and the energy consumption of the steel structure workshop can be sharply reduced by 30-70%.

2. Ventilation and cooling of steel structure workshop

Because 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 of the steel structure workshop will increase and affect the environment of the steel structure workshop. The way to deal with these problems is to ensure the fair ventilation of the workshop and to equip the appropriate ventilation system. Equitable exhaust system equipment will significantly improve the air environment of the steel structure workshop and greatly reduce the temperature of the steel structure workshop. The unpowered ventilator on the equipment roof is a ventilation device that relies on the principle of air convection to ventilate. When the air environment inside and outside the room is different, air movement will occur, and then the indoor exhaust gas and hot air will be cleaned. The benefit 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 turbine ventilator, strip ventilator (lighting belt ventilation), roof ventilator and so on. Steel structure workshop equipment roof forced exhaust fan Power fan is a kind of ventilation equipment driven by electricity. Its exhaust effect is good, and it can adapt to the ventilation of any environment.

3. Forced cooling of steel structure workshop

Forced cooling refers to the installation of a cooling fan on the factory floor. The cooling fan uses the principle of water cooling to cool the air, and the strong exhaust fan delivers the cool air to the indoor machine. It can keep the indoor temperature of the steel structure workshop 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, which is a good way to force the cooling of the workshop.
