右图为国外最新研制成功的一款新颖的室外冷气太阳伞。其外观与高级太阳伞没什么分别,直径为2.1米,高2.57米。但其伞布均采用了能反射光和热的隔热玻璃纤维遮阳布为材料,并在伞顶装置了一套专门设计的特殊制冷设备,使以伞为中心的四周每分钟可获得15立方米的清凉空气。同时,可通过调控制冷疫备,调节伞内外气温保持在10～12℃之间,确保伞内清凉舒适。
The figure on the right shows a new type of outdoor air-conditioned parasol that has been successfully developed abroad. Its appearance is no different from that of an advanced sun umbrella, with a diameter of 2.1 meters and a height of 2.57 meters. However, the umbrella fabrics are made of heat-insulating glass fiber sunscreens that reflect light and heat, and a specially designed special refrigeration device is installed on the umbrella top so that 15 cubic meters per minute can be obtained around the center of the umbrella. m cool air. At the same time, it is possible to regulate the temperature of the inside and outside of the umbrella to be maintained between 10 and 12°C by regulating the cooling and epidemic preparations to ensure that the umbrella is cool and comfortable.
