钢结构厂房如何降温

钢结构厂房的冷却是一个综合性问题。要解决这一问题,就必须找出影响钢结构厂房温度的关键因素,重点进行控制,然后选择合适的方法来处理其他相对较小的因素,才能达到良好的室内环境和高温。性能和价格。比率。

为了降低钢结构车间的温度,应考虑以下问题:
1. 钢结构厂房通风性能如何?
2. 钢结构厂房有冷却系统吗?
3. 钢结构厂房的保温性能如何?
01钢结构厂房通风冷却
由于钢铁厂的一些机器产生热量和蒸汽,如果这些热量和蒸汽不能及时排出,就会在钢铁厂内积聚,从而提高钢铁厂的温度,影响钢铁厂的环境。解决这些问题的方法是保证车间的合理通风,安装合适的通风系统。合理安装排风系统将大大改善钢结构车间的空气环境,大大降低钢结构车间的温度。
02钢结构二车间强制冷却
强制冷却是指在厂房屋顶安装冷却风机。冷却风机是利用水冷原理对空气进行冷却,并通过强力排风机将冷空气送至房间的机器。钢结构厂房室内温度维持在26-30℃,耗电量相当于空调的1/8。其成本仅为空调的1/2,是强制冷却装置的一种好方法。
03三钢结构厂房保温降温
钢结构厂房的保温可以隔离大部分的太阳辐射和传热,减少室内温室效应。从而大大降低了车间的温度,改善了钢结构车间的环境。有两种选择:
1、钢结构厂房屋顶加保温棉。屋顶保温棉一般采用玻璃棉。保温棉的厚度为50m、75mm、100mm,密度为10kg/m,安装保温棉一般能使室内温度降低3-5℃,施工过程较为复杂。如果老厂改成保温棉,就要拆除原来的屋顶,拉起铁丝网。将玻璃棉铺在钢丝网上,覆盖原屋面板然后做防水处理。
2.屋面板采用高效隔热反光涂料。该产品具有良好的隔热性能,可直接喷涂在金属屋顶上。裂谷冷却屋顶系统是一个白色的反射隔热涂料喷涂在您的工厂在美国的屋顶。该系统具有良好的耐热性和抗紫外线性,能充分反射85%的太阳光和94%的太阳能。防火等级A,完全不可燃。无毒、安全、持久。采用这种方法,施工方便,不破坏原有屋面,可防止屋面老化。

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?
3。 How 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 structure workshop
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.
