The cooling of structural workshop is a comprehensive problem. To solve this problem, we must find out the key factors that affect the temperature of steel structure workshop, focus on the control, and then select appropriate methods to deal with other
relatively small factors, in order to achieve a good indoor environment and high temperature. Performance and price. Ratio.
In order to reduce the temperature of steel structure workshop, the following problems should be considered:
1。 How about the ventilation performance of steel structure workshop?
2。 Is there a cooling system in the steel works?
about the thermal insulation performance of steel structure workshop?
Ventilation and cooling of 01 steel structure workshop
Because some machines in iron and steel plant produce heat and steam, if these heat and steam cannot be discharged
in time, they will accumulate in the plant, which will increase the temperature of iron and steel plant and affect the environment of iron and steel plant. The way to solve these problems is to ensure the reasonable ventilation of the workshop and install
the appropriate ventilation system. Reasonable installation of exhaust system will significantly improve the air environment of steel structure workshop and greatly reduce the temperature of steel structure workshop.
Forced cooling of 02 No.2 steel
Forced cooling refers to the installation of cooling fans on the roof of the plant. The cooling fan is a machine that uses the water cooling principle to cool the air and send the cold air to the room through the powerful exhaust
fan. The indoor temperature of steel structure workshop is maintained at 26-30 ℃, and the power consumption is equivalent to 1 / 8 of air conditioning. Its cost is 1 / 2 of that of air conditioning, which is a good method of forced cooling plant.
03 three steel structure workshop thermal insulation and cooling
The thermal insulation of steel structure workshop can isolate most of the solar radiation and heat transfer, and reduce the indoor greenhouse effect. Thus, the temperature of the
workshop is greatly reduced and the environment of the steel structure workshop is improved. There are two options:
1。 The roof of steel structure workshop is added with insulation cotton. Generally, glass wool is used as insulation cotton for roof.
The thickness of insulation cotton is 50 m, 75 mm, 100 mm, and the density is 10 kg / m. The installation of insulation cotton can generally reduce the indoor temperature by 3-5 ℃, so the construction process is more complicated. If the old factory is
changed into insulation cotton, the original roof should be removed and the wire mesh should be pulled up. Lay the glass wool on the wire mesh, cover the original roof panel, and then do waterproof treatment.
2。 High efficiency thermal insulation
and reflective coatings are applied to roof panels. The product has good heat insulation performance, and can be directly sprayed on the metal roof. The rift cool roof system is a white reflective thermal insulation coating sprayed on the roof of your
factory in the United States. The system has good heat resistance and anti ultraviolet linearity, and can fully reflect 85% of the sun and 94% of the solar energy. Fire rating A, completely nonflammable. Non toxic, safe and lasting. If this method is
adopted, the construction is convenient, the original roof is not damaged, and the aging of the roof can be prevented.
