节能重要的是使门具有高强度、高气密性、高水密性、高精度性、优秀的隔热、隔音功用。快速门节能的关键是在其运用功用的前提下，具有较高的保温性和隔热功用。关于工作和消费车间，夏天用空调制冷，冬天用暖气或电热器取暖已成必备条件。
The important aspect of energy-saving is to make the door have high strength, high airtightness, high water tightness, high precision, and excellent insulation and sound insulation functions. The key to energy-saving of fast doors is to have high insulation performance and insulation function under the premise of their application function. Regarding work and consumption workshops, using air conditioning for cooling in summer and heating with heating or electric heaters in winter have become essential conditions.
快速门高度的密封隔热功用有用的防止空气的丢掉，而且快速门升降速度0.7m/s-2.1m/s,通过快速打开闭合隔绝空气。在冬天酷寒的气候，室表里温差较大，假设气密性不高，室表里空气构成压力差。
The sealing and insulation function of the height of the fast door effectively prevents the loss of air, and the lifting speed of the fast door is 0.7m/s-2.1m/s, which isolates air by quickly opening and closing. In the extremely cold climate of winter, there is a large temperature difference between the surface and interior of the room. Assuming that the air tightness is not high, the pressure difference between the surface and interior of the room is formed.
室外冷空气通过缝隙室内，构成室温动摇，影响室内并耗费大量热能，这种现象我们称之为"冷风渗透";而在夏季火热气候，室外的高温气候及室内选用空调制冷，空气活动发生的热风通过缝隙室内，制冷能耗。

The outdoor cold air passes through the gaps inside, causing room temperature to fluctuate, affecting the interior and consuming a large amount of heat energy. This phenomenon is called "cold air infiltration"; In the hot summer climate, outdoor high temperature climate, and indoor air conditioning cooling, the hot air generated by air activities passes through the crevices indoors, resulting in energy consumption for cooling.
无论是酷寒仍是火热，在气密性不好的情况下，室表里的温差都将耗能的，因而，快速门的气密功用是其节能的一个重要措施。快速门选用新式高频焊接技术，全自动拼接一次成型，且 门帘底部装有气囊布兜，能同各种不平整空中密封别离，导轨内置毛刷，以到达高度密封作用
Whether it is extremely cold or hot, the temperature difference in the room surface will consume energy under poor airtightness. Therefore, the airtightness function of the quick door is an important energy-saving measure. The fast door adopts new high-frequency welding technology, fully automatic splicing and one-time molding, and the bottom of the door curtain is equipped with an airbag cloth pocket, which can seal and separate from various uneven air spaces. The guide rail is equipped with a brush to achieve a high sealing effect
