Ventilation and heat removal of steel structure workshop?

It is a comprehensive problem to choose the right method to cool the steel structure plant. To solve this problem, we should find the key factors affecting the temperature of the steel structure plant and deal with other relatively minor factors to achieve good indoor environment and cost performance.

Because some machines in the steel structure workshop will produce heat and steam, if the hot air and steam can not be discharged in time, they will accumulate in the workshop, thereby increasing the temperature of the steel structure workshop, affecting the environment of the steel structure. Structural workshop. The solution to these problems is to ensure proper ventilation of the workshop and install a proper exhaust system. The reasonable installation of the discharge system will greatly improve the air environment of the steel structure workshop and greatly reduce the temperature of the steel structure workshop. Install roof forced exhaust fans. Power fan is a kind of ventilation equipment driven by electricity. Unpowered ventilator is a kind of ventilation equipment based on the principle of air convection. When the indoor and outdoor air environment is different, airflow will be generated, and then the indoor exhaust gas and hot air will be removed. The advantage is that no extra power is needed and it is more environmentally friendly. However, it is highly dependent on the environment, so it cannot be forced to run out. The main products are turbine fan, belt fan (lighting with ventilation), roof fan and so on.

Forced cooling of steel structure plant is the installation of an air cooler on the roof of the factory building. An air cooler is a machine that uses the principle of water cooling to cool air, forcing exhaust fans to deliver cold air to the room. The indoor temperature of the steel structure workshop can be kept at a comfortable temperature of 26-30 ℃. Its power consumption is equivalent to 1/8 of air conditioning. The cost is 1/2 of the cost of air conditioning, which is a good way to force cooling the workshop.

The insulation layer of steel structure workshop can isolate most of the solar radiation and heat conduction, and reduce the indoor greenhouse effect. This greatly reduces the temperature of the workshop and improves the environment of the steel structure workshop. Today, there are two common approaches:

Thermal insulation cotton covers the roof of the steel factory building. The insulating wool used on roofs is usually glass wool. The thickness is generally 50mm, 75mm, 100mm, density is 64kg/m3. Generally, the indoor temperature can be reduced by 5-8 ° C after installation, and the construction process is complex. If the old factory building is renovated with insulation, the original steel wire mesh needs to be removed, glass wool is spread on the glass net, the original roof is covered, and then waterproof treatment is carried out.
