Thermal insulation of prefabricated steel structure workshop

How to cool down the prefabricated steel structure workshop is a problem that many business owners are very concerned about. Summer is very hot in many countries and regions. It is difficult for people to maintain enthusiasm for work in a high temperature environment. Before building a steel structure workshop, it is necessary to consider the problem of thermal insulation of a prefabricated steel structure workshop.

There are many ways to insulate a prefabricated steel structure workshop. The common ones are ventilation and heat removal, thermal insulation material insulation, cooling equipment insulation, etc. Owners can choose different insulation measures according to different insulation requirements.

1. Ventilation and heat removal:

The circulation of air can transfer heat to the outside of the workshop, and the temperature inside the workshop is much lower than that of the outside. There are several ways to increase the circulation of indoor air:

① Arrange more doors and windows to speed up air convection and take away the high-temperature indoor air;
②Ventilation ball/air building, this method uses the physical principle that the density of hot air will rise, quickly discharges the hot air inside the workshop, and transfers the indoor heat to the outdoors, which is a widely used measure at present.

2. Insulation material:

The use of thermal insulation materials in prefabricated steel workshops is now the most common practice. Many prefabricated steel structure workshops use color steel plates as maintenance materials for roofs and walls. The advantages of color steel plate are low cost and convenient installation. However, the thermal insulation ability of color steel plates is very poor. In summer, the temperature can reach 72 degrees Celsius when the sun is directly shining, and the temperature inside the workshop will also reach more than 40 degrees Celsius. The workshop uses thermal insulation materials, and the internal temperature can be reduced by 5-12 degrees Celsius.

The lower the thermal conductivity of the thermal insulation material, the better the thermal insulation ability. For materials of the same thickness, comparison of thermal insulation capabilities: polyurethane > rock wool > glass wool > EPS. Owners can choose different types and thicknesses of thermal insulation materials according to the usage environment and budget.

3. Insulation of cooling equipment:

The owner chooses the cooling equipment suitable for the prefabricated steel structure workshop for cooling.

①Environmental protection air conditioner, a single unit with 20,000 air volume can cool down 100-150 square meters. It cools the air outside the workshop and sends it into the workshop to cool down. The fan blows air into the workshop, and the fresh outdoor air flows through the wet curtain soaked in water, and the air fully contacts with the moisture to absorb the air heat. It can achieve the effects of cooling, ventilation, dust removal and increasing the oxygen content of the air in the workshop. Environmentally friendly air conditioning is very important to audit workshops with dense workers and more dust.

② Large industrial fan, diameter 3m—7.3m optional, power 0.55—1.5KW. It has a large air volume and a wide coverage area. A single machine can ventilate and cover a workshop area of ​​1800 square meters. The large fan pushes the airflow to the ground in a cone shape from top to bottom, and flows in the horizontal direction when it reaches the ground. When it encounters the horizontal airflow from the side block or the adjacent fan, it pushes it upward to the roof to achieve effective all-round overall ventilation for the workshop environment and personnel. Effective cooling.
