Choosing the right method to cool down the steel structure plant is a comprehensive issue. To solve it, it is necessary to take appropriate measures. First of all, we must find the key factors that affect the temperature of the steel structure plant, and focus on its governance. Other relatively minor factors will be targeted by law. The treatment achieves a good indoor environment, and its cost performance is high.

The following issues should be considered for cooling the steel structure plant：

1. What is the thermal insulation performance of the steel structure plant?

2. Does the steel structure plant have a cooling system?

3. What is the ventilation performance of the steel structure plant?

Ventilation and cooling of a steel structure plant

Because some machines in the steel structure plant will produce heat and water vapor, if these heat and water vapor are not discharged in time, they will accumulate in the plant, causing the temperature of the steel structure plant to increase, affecting the steel structure of the environmental structure of the plant. The way to solve these problems is to ensure reasonable ventilation of the plant and install an appropriate amount of ventilation system. The reasonable installation of the exhaust system will significantly improve the air environment of the steel structure plant and greatly reduce the temperature of the steel structure plant.

Installation of roof forced exhaust fan

A power fan is a kind of ventilation equipment powered by electricity. The exhaust effect is good, and it can adapt to the ventilation and ventilation of any environment.

An unpowered ventilator is a kind of ventilation equipment that relies on the principle of air convection. When there is a difference in the indoor and outdoor air environment, air flow will be generated, thereby eliminating indoor exhaust and hot air. The advantage is that no additional power is required and it is more environmentally friendly. But it is very dependent on the environment and cannot be forcibly discharged. The main products are turbine ventilators, strip ventilators (lighting and ventilation), roof ventilators, etc.

Install a roofless electric ventilator. An unpowered ventilator is a kind of ventilation equipment that relies on the principle of air convection. When there is a difference in the indoor and outdoor air environment, air flow will be generated to exclude indoor exhaust gas and hot air. The advantage is that no additional power is required and it is more environmentally friendly. But it is very dependent on the environment and cannot be forcibly discharged. The main products are turbine ventilators, strip ventilators (lighting and ventilation), roof ventilators, etc.

Forced cooling of two steel structure plants

Forced cooling refers to the installation of cooling fans on the roof of the plant. The air cooler uses the principle of water cooling to cool the air, and the powerful exhaust fan sends the cold air to the indoor unit. It can keep the indoor temperature of the steel structure plant at a comfortable temperature of 26-30℃. Its power consumption is equivalent to 1/8 of that of an air conditioner. The cost is 1/2 of that of air conditioning, which is a good way to force plants to cool down.

Three steel structure plant insulation and cooling

The thermal insulation of the steel structure plant can isolate most of the solar radiation and heat conduction, and reduce the indoor greenhouse effect. Thereby greatly reducing the temperature of the plant and improving the environment of the steel structure plant. There are two options for the commonly used methods now：

Cover the roof of the steel structure plant with thermal insulation cotton. The thermal insulation cotton used on the roof is glass wool. The commonly used thicknesses are 50mm, 75mm, and 100mm, and the density is 64kg/m3.

After installation, the indoor temperature can generally be reduced by 5-8℃. The construction process is more complicated. If the old factory is undergoing thermal insulation transformation, the original roof needs to be removed, the steel wire mesh is pulled out, and glass wool is laid on the steel wire mesh to cover the original roof panels. Then do waterproof treatment.

Roof panels are sprayed with high-efficiency heat-reflective coatings. The product has excellent thermal insulation properties and can be applied to various surfaces such as metal, concrete, gray walls, wooden structure surfaces, asbestos tiles, plastics, glass fiber reinforced plastic, rubber, etc. The coating thickness is 0.25mm, and its effect is equivalent to 250px-375px glass wool. It can reflect 99.5% of infrared light and 92.5% of visible light. The highest sound insulation effect is 68%, and the average sound insulation effect is more than 50%. Fireproof grade A, completely non-combustible. It is very safe, durable, and has a service life of more than 15 years (see the engineering information document for details). If this method is used, the construction is convenient and does not destroy the original roof, which can prevent the roof from aging. The maximum temperature difference between the surface of the sheet after construction and before construction can reach 20℃, and the indoor temperature difference can reach 8-10℃, and the energy consumption of the steel structure plant can be reduced by 30-70%.
