Steel structure cooling is a comprehensive title. The steel structure factory needs to deal with this problem when dealing with this problem. First of all, it is necessary to find the first factor that affects the temperature increase of the steel structure factory, focusing on the treatment of one-sided problems, and then selecting the appropriate method. The relatively unnecessary elements will be processed to achieve an excellent indoor environment and the highest cost performance.
一、Insulation and cooling of steel structure workshop
Insulation film of steel structure workshop can isolate most of the solar radiation and conduction heat, reducing the indoor greenhouse effect. Then the temperature of the plant is greatly reduced to improve the environment of the steel structure plant.
At present, there are two common methods to choose: to cover the roof of the steel structure factory with insulation cotton. The insulation cotton used on the roof is glass wool. The commonly used thickness is 50mm, 75mm, 100mm, and the density is 10kg / m. The equipment is generally good. The indoor temperature is reduced by 5-8 ℃, and the construction process is messy. If the insulation of the old plant is renovated, the original roof needs to be cancelled, the steel wire mesh is pulled, the glass wool is laid on the steel wire mesh, and the original roof panel is covered with the steel structure, then Waterproof treatment. Spray high-efficiency heat-reflective coating on the roof panel. This product has excellent thermal insulation performance, and the steel structure can be coated on various surfaces such as metal, concrete, gray walls, wooden structure surfaces, asbestos tiles, plastics, glass steel, and rubber. The coating is 0.25mm thick, and its effect is equivalent to that of 10cm-15cm glass wool. It can reflect 99.5% infrared rays and 92.5% visible light. The highest sound insulation effect is 68%, and the steel structure factory uniform sound insulation effect is more than 50%. Fire-proof grade A, completely non-combustible. Non-toxic safety, long-lasting durability, service life of more than 15 years (refer to engineering materials file for specific introduction). If this method is used, the construction is convenient, no damage to the original roof, and it can restrain the aging of the roof. After construction and before construction, the maximum temperature difference between the surface of the plate can reach 20 ℃, the indoor temperature difference can reach 8-10 ℃, and the energy consumption of the steel structure workshop can be reduced by 30-70%.
二、Steel structure workshop ventilation and cooling
Because some machines in the steel structure factory generate heat and water vapor, these hot gases and water vapor are assumed to be not discharged in time, they will accumulate in the factory, and then increase the temperature of the steel structure factory to affect the environment of the steel structure factory. The way to deal with these problems is to ensure a fair ventilation of the plant, and an appropriate ventilation system with appropriate equipment. Fair air exhaust system equipment will significantly improve the air environment of the steel structure plant, and greatly reduce the temperature of the steel structure plant. Equipment roofless power ventilator is a kind of ventilation device that relies on the principle of air convection. When there is a difference in the air environment in the room surface, air activity will occur, and then the indoor exhaust and hot air will be cleaned. The benefit is that it does not require additional power and is more environmentally friendly. However, it has a strong dependence on the environment and cannot force exhaust. The products mainly include turbine ventilators, strip ventilators (daylighting ventilators), roof ventilators, etc. The forced exhaust fan of steel structure factory equipment roof is a kind of ventilation equipment driven by electricity. It has good exhaust effect and can get used to the ventilation of any environment.
三、Steel structure factory forced cooling
Forced cooling refers to the cooling fan in the factory roof equipment. The cooling fan uses the principle of water cooling to cool the air, and the strong exhaust fan sends the cooling air to the indoor machine. It can keep the indoor temperature of the steel structure workshop at a quiet temperature of 26-30 ℃. Its power consumption is equal to 1/8 of the air conditioner. The cost is 1/2 of the air conditioner, which is a good way to force the plant to cool down.
