In recent years, after continuous development, rolling shutter door has been used in all walks of life, how to use it to achieve energy-saving effect? The experience of Jinan roller shutter door is as follows:

卷帘门重要的是使门具有高强度、高气密性、高水密性、高精度性、优异的隔热、隔音性能。关键是在满足其使用功能的前提下，具有较高的保温性和隔热性能。对于办公室和生产车间，夏天用空调制冷，冬天用暖气或电热器取暖已成必备条件。其中的能源消耗对企业来说是一笔不小的费用。高度的密封隔热性能有效的防止空气的流失，隔绝空气。

Energy saving of rolling shutter door is important to make the door have high strength, high air tightness, high water tightness, high precision, excellent heat insulation and sound insulation performance. The key is to have high thermal insulation and thermal insulation performance on the premise of meeting its use function. For offices and workshops, it is necessary to use air conditioning in summer and heating or electric heater in winter. The energy consumption is not a small cost for enterprises. High sealing and heat insulation performance can effectively prevent air loss and isolate air.

在冬季寒冷的天气，室内外温差较大，如果气密性不高，导致室内外空气形成压力差，室外冷空气通过缝隙进入室内，造成室温剧烈波动，影响室内环境并消耗大量热能，这种现象我们称之为“冷风渗透”;而在夏季炎热天气，室外的高温天气及空调制冷，空气流动产生的热风通过缝隙进入室内，导致制冷能耗增加。

In the cold weather in winter, the temperature difference between indoor and outdoor is large. If the air tightness is not high, the indoor and outdoor air will form pressure difference. The outdoor cold air enters the room through the gap, causing the room temperature to fluctuate violently, affecting the indoor environment and consuming a lot of heat energy. This phenomenon is called "cold air infiltration"; However, in hot summer weather, outdoor high temperature weather and indoor air conditioning refrigeration, the hot air generated by air flow enters the room through the gap, which leads to the increase of refrigeration energy consumption.

无论是寒冷还是炎热，在气密性不好的情况下，室内外的温差都将导致耗能的增加，因此，卷帘门的气密性能是其的一个重要措施。采用新型高频焊接技术，全自动拼接一次成型，且门帘底部装有气囊布兜，能同各种不平坦地面密封结合，导轨内置毛刷，以达到高度密封效果。

Whether it is cold or hot, in the case of poor air tightness, the temperature difference between indoor and outdoor will lead to the increase of energy consumption. Therefore, the air tightness performance of rolling shutter door is an important measure of energy saving. It adopts new high frequency welding technology, fully automatic splicing and one-time forming, and the bottom of curtain is equipped with air bag pocket, which can be combined with various uneven ground sealing, and the guide rail has built-in brush to achieve high sealing effect.

还有卷帘门的隔热效果。同时装有热水的两瓶，开口的比密封的冷得快，而同时密封的两热水瓶，玻璃瓶要比塑料瓶冷得快。后者的现象表现在材质间的区别。只要存在温差就无法避免热传递，热传递的途径主要是热对流、热传导、和热辐射。密封性能和材质性能以及表面工艺的光滑能分别在对流、传导、辐射三方面减少热能的损失达到效果。我们的门帘材料选择进口的工业聚酯纤维布，高强度聚酯纤维，隔热性好，双面聚氯乙烯涂层，光滑美观。通过快速开启闭合，具有的功效。

There is also the thermal insulation effect of rolling shutter doors. For two bottles containing hot water at the same time, the open one is cooler than the sealed one, while for the two thermos bottles sealed at the same time, the glass bottle is cooler faster than the plastic bottle. The latter phenomenon is shown in the difference between materials. As long as there is temperature difference, heat transfer cannot be avoided. The main ways of heat transfer are heat convection, heat conduction and heat radiation. The sealing performance, material performance and smooth surface technology can reduce the loss of heat energy in convection, conduction and radiation respectively, so as to achieve energy saving effect. Our curtain materials choose imported industrial polyester fiber cloth, high strength environmental protection polyester fiber, good thermal insulation, double-sided PVC coating, smooth and beautiful. Through fast opening and closing, it has excellent energy saving effect.
