Choosing the appropriate method to cool the steel structure factory building is a comprehensive issue. To address this issue, we should identify the key factors that affect the temperature of steel structure factories and address other relatively minor factors to achieve good indoor environment and cost performance.
1. Ventilation and heat dissipation of steel structure factory buildings.
Due to the fact that some machines in the steel structure factory generate heat and steam, if the hot air and steam cannot be discharged in a timely manner, they will accumulate in the workshop, thereby increasing the temperature of the factory and affecting the environment of the steel structure. Structural workshop. The solution to these problems is to ensure reasonable ventilation in the workshop and install an appropriate exhaust system. Reasonable installation of emission systems will greatly improve the air environment of steel structure factories and greatly reduce the temperature of the factories.
2. Install roof forced exhaust fan.
A power fan is a ventilation device driven by electricity. Good exhaust effect, able to adapt to ventilation in any environment.
An unpowered ventilator is a ventilation device based on the principle of air convection. When the indoor and outdoor air environments are different, airflow will be generated to remove indoor waste gas and hot air. Its advantage is that it does not require additional power and is more environmentally friendly. However, it is highly dependent on the environment, so it cannot be forced to exhaust. The main products include turbine ventilation fans, belt ventilation fans (lighting belt ventilation), roof ventilation fans, etc.

3. Forced cooling of two steel structure factories.
Forced cooling refers to installing an air cooler on the roof of a factory building. An air cooler is a machine that uses the principle of water cooling to cool air, and a forced exhaust fan delivers cold air to the room. The indoor temperature of the steel structure factory building can be maintained at a comfortable temperature of 26-30 ° C. Its power consumption is equivalent to 1/8 of that of an air conditioner. The cost is half of the cost of air conditioning and is a good method for forced cooling workshops.
4. Steel structure factory building insulation and cold insulation.
The insulation layer of the factory can isolate most of the solar radiation and heat conduction, reducing the indoor greenhouse effect. This greatly reduces the temperature in the workshop and improves the environment of the factory building. Nowadays, there are two common methods:
The insulation cotton covers the roof of the steel structure factory building. The insulation cotton used on the roof is usually glass wool. The thickness is generally 50mm, 75mm, 100mm, and the density is 64kg/m3.
After general installation, the indoor temperature can be reduced by 5-8 ℃, and the construction process is complex. If the steel structure factory building undergoes insulation renovation, it is necessary to remove the original steel wire mesh, lay glass wool on the glass mesh, cover the original roof, and then carry out waterproofing treatment.
