Insulation of steel structure factory can cut off most of the solar radiation and heat conduction and reduce the indoor greenhouse effect, thus greatly reducing the temperature of the plant and improving the environment of the steel plant.The commonly used methods have the following two options: Steel structure factory roof covered with insulation cotton, general insulation cotton roof is glass wool, commonly used thickness of 50mm, 75mm, 100mm, density of 10kg / m installed can generally reduce the indoor temperature of 5-8 ℃, the construction process is more Complex, if the old plant to do thermal insulation transformation, the need to demolish the original roof, pull the wire mesh, glass wool laying in the wire mesh, cover the original roofing, waterproofing treatment .In the roofing spray efficient insulation reflective coating The thermal insulation of this kind of product is very good and can be coated on various surfaces such as metal, concrete, gray wall, wood surface, asbestos, plastic, FRP, rubber, etc. The coating is 0.25mm thick, the effect is equivalent to 10cm -15cm glass wool effect, it can reflect 99.5% infrared, 92.5% of visible light, the highest soundproof effect of 68%, plant uniform noise effect of more than 50% Completely non-flammable Non-toxic and safe, long-lasting and durable, the service life of more than 15 years (specific introduction can refer to the engineering materials file) .If this method, construction convenience, no damage to the original roof, but also to prevent the roof aging. After the construction and before the plate surface temperature up to 20 ℃, the indoor temperature difference of up to 8-10 ℃, steel structure factory energy consumption can be sharp reduction of 30-70%.
Because some machines in the steel structure produce heat and water vapor, these hot gases and water vapor will accumulate in the plant if they are not discharged in time, so that the temperature of the steel structure factory will affect the environment of the steel structure factory. The solution to these problems is to ensure that the plant is open and air-ventilated, and the right amount of ventilation system installed. The installation of a fair exhaust system will significantly improve the air environment of steel tructure factory, a larger steel tructure factory to reduce the temperature. Installation of roofless motive ventilator No motive ventilator is an air permeable device that relies on air convection principle to ventilate. When there are differences between indoor and outdoor air environment, air activity will be generated to eliminate indoor exhaust gas and hot air. Its strength is that it does not require additional power and is more environmentally friendly. However, the strong dependence on the environment can not be forced to exhaust. The main products are Turbocharger, strip-shaped ventilation (with light with ventilation), such as roof breather. Factory installation roof forced exhaust fan power fan is powered by a kind of ventilation equipment. Its exhaust effect is good, can adapt to any environment of ventilation. Non-powered air diffuser is air-permeable device that relies on the air convection principle to ventilate. When there are differences between indoor and outdoor air environments, air activities are generated, thereby eliminating indoor exhaust gas and hot air. Its strength is that it does not require additional power and is more environmentally friendly. However, the strong dependence on the environment can not be forced to exhaust. The main products are Turbocharger, strip-shaped ventilation (with light with ventilation), such as roof breather.
Forced cooling refers to the installation of the roof of the factory chiller, chiller is the use of water cooling principle of cooling air, the strong exhaust fan to deliver cold air to the indoor machine. It allows the plant room temperature maintained at a quiet temperature of 26-30 ℃. Its power consumption is equivalent to 1/8 of the air conditioner. Cost is air-conditioned 1/2, is a good way to cool the plant forced.
