可利用太阳辐射热能量,以双层塑料棚保暖。其原理是双层间隔,起到真空隔离保暖作用。具体做法如图示。①先架里层框架;②外层框架作成活络式,可取下;③如阳台为水泥地面,框架内要垫泡沫塑料板或干草;如为带隔层的地面,可只垫干草;④棉帘外层最好罩塑膜,更利保温(棉帘晒热),还可防雨。保暖棚尺寸自定。框架一定要严格。根据各地区 Can use solar radiation heat energy, double plastic shed warm. The principle is double-spaced, play a role in vacuum insulation. The specific approach as shown. ① the first frame of the inner frame; ② the outer frame made of live, removable; ③ If the balcony is a concrete floor, the frame to be padded foam board or hay; Cover the best outer cover plastic film, more insulation (cotton curtain sun), but also rain. Warm shed size custom. The framework must be strict. Depending on the area
