In this study, the performances of three commonly used greenhouse shapes even-span, uneven-span, and elliptic are compared in the climatic conditions of Marrakech, Morocco. The dimensions (length, width, and height) of the greenhouse types are kept the same. A mathematical model for computing the total hourly solar irradiation gained by each greenhouse shape during the whole year was developed for both north–south and east–west orientations. This model is applicable and suitable for other shapes and locations in the world. Hourly and monthly solar irradiation transmitted inside the greenhouse system were computed individually for all studied greenhouse types and orientations. An extensive comparison was then made to determine the most suitable greenhouse shape and orientation for our site (Marrakech). The results show that the uneven-span shape greenhouse with a roof inclination angle of 12° is the optimum one as it receives the maximum solar irradiation, followed by the even-span with a roof inclination angle of 17° and finally by the elliptical shape. The shape, type, and surface of the roof are the main effective parameters on solar energy availability in greenhouses. East–west orientation is the most suitable configuration for drying applications during winter as it receives more significant solar irradiation in this season. It was found that the uneven-span greenhouse with a roof inclination angle of 12° and oriented east–west is preferred for Marrakech in this regard.

摩洛哥马拉喀什气候条件下温室形状和方向的比较研究

本研究在摩洛哥马拉喀什的气候条件下比较了三种常用的温室形状偶跨、不等跨和椭圆形的性能。温室类型的尺寸(长、宽和高)保持不变。针对南北和东西方向开发了一个数学模型,用于计算全年每个温室形状获得的每小时太阳辐射总量。该模型适用于世界上其他形状和地点。对于所有研究的温室类型和方向,单独计算温室系统内传输的每小时和每月的太阳辐射。然后进行了广泛的比较,以确定最适合我们场地(马拉喀什)的温室形状和方向。结果表明,屋顶倾角为12°的不等跨形状温室是最佳的,因为它受到的太阳辐射最大,其次是屋顶倾角为17°的等跨,最后是椭圆形。 . 屋顶的形状、类型和表面是温室中太阳能可用性的主要有效参数。东西向是冬季干燥应用最合适的配置,因为它在这个季节会受到更多的太阳辐射。研究发现,在这方面,马拉喀什更喜欢屋顶倾角为 12°、东西向的不均匀跨度温室。其次是屋顶倾角为 17° 的偶跨,最后是椭圆形。屋顶的形状、类型和表面是温室中太阳能可用性的主要有效参数。东西向是冬季干燥应用最合适的配置,因为它在这个季节会受到更多的太阳辐射。研究发现,在这方面,马拉喀什更喜欢屋顶倾角为 12°、东西向的不均匀跨度温室。其次是屋顶倾角为 17° 的偶跨,最后是椭圆形。屋顶的形状、类型和表面是温室中太阳能可用性的主要有效参数。东西向是冬季干燥应用最合适的配置,因为它在这个季节受到更显着的太阳辐射。研究发现,在这方面,马拉喀什更喜欢屋顶倾角为 12°、东西向的不均匀跨度温室。
