现代温室的设计是基于在经济范围内最大化太阳辐射传输和最小化热损失之间的折衷。这可以通过使用透明的双层之字形板作为覆盖材料来满足。MatLight计算机模型被开发用于计算由于使用这些板而对温室覆盖物的传输的影响。用双之字形板覆盖没有构造元件如排水沟和玻璃条的温室盖，其跨度为3.2m，屋顶坡度为25度。该温室被证明有1.6%的漫透射损失和增益的透射直接辐射高达5%，在冬季的NS方向，与单玻璃覆盖。覆盖层的绝缘性提高了16%。这是一个有希望的实际应用结果。(C)2001年，Silsoe研究所。
The design of modern greenhouses is based on a compromise between a maximized transmission of solar radiation and a minimized heat loss within an economic context. This could be satisfied by the use of transparent double-layered zigzag plates as a covering material. The MatLight computer model was developed to compute the effect on transmission of a greenhouse cover due to the use of these plates. A greenhouse cover without construction elements such as gutters and glazing bars, with a span width of 3.2 m and a roof slope of 25 degrees, was covered with a double zigzag plate. This greenhouse was proved to have a diffuse transmission loss of 1.6% and a gain in transmitted direct radiation up to 5% in winter for NS-orientation, compared with a single-glass cover. The insulation of the cover increases by 16%. This is a promising result for practical application. (C) 2001 Silsoe Research Institute.
