Energy saving principle of fast rolling shutter door

Energy saving 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 to energy saving of fast door is that it has high thermal insulation and thermal insulation performance on the premise of its application function. For office and consumer workshops, it has become a necessary condition to use air conditioning for refrigeration in summer and heating or electric heater in winter. The high sealing and thermal insulation performance of the fast door can effectively avoid the loss of air, and the lifting speed of the fast door is 0.7m/s-2.1m/s, which is isolated from the air through rapid opening and closing. In the cold weather in winter, the indoor and outdoor temperature difference is large. If the air tightness is not high, the indoor and outdoor air constitutes a pressure difference. The outdoor cold air passes through the gap and the room temperature shakes, which affects the room and consumes a lot of heat energy. This phenomenon is called "cold air infiltration"; In the hot summer weather, outdoor high temperature weather and indoor air conditioning refrigeration, the hot air generated by air activities passes through the gap indoor, which reduces the refrigeration energy consumption. Whether it is cold or hot, the temperature difference between indoor and outdoor will consume energy under the condition of poor air tightness. Therefore, the air tightness of fast door is an important measure of energy saving. The fast door adopts new high-frequency welding technology, fully automatic splicing and one-time forming, and the air bag cloth pocket is installed at the bottom of the door curtain, which can be sealed and separated from various uneven air. The guide rail is equipped with a brush to achieve a high sealing effect.
