怎么选择温室的通风系统?

  植物生长需要合适的温度和湿度。 相应地,温室需要通风系统来调节和控制室内的温度和湿度,以为植物提供合适的生长环境。 通常,温室通风系统可分为自然通风和强制通风。 所谓自然通风,是指利用温室表面的温度差或风压的开放式温室或天窗的侧窗,完成温室表面的空气对流,并降低温室的温度和湿度 。 所谓的强制通风是通过启动风扇等迫使温室中的空气对流,以调节温室中的温度和湿度。 两种通风方式各有特点,适用于不同的场景。
  Proper temperature and humidity are needed for plant growth. Accordingly, the greenhouse needs ventilation system to regulate and control the temperature and humidity in the room, so as to provide suitable growth environment for plants. Generally, greenhouse ventilation system can be divided into natural ventilation and forced ventilation. The so-called natural ventilation refers to the use of the greenhouse surface temperature difference or wind pressure of the open greenhouse or the side window of the skylight to complete the air convection on the greenhouse surface and reduce the temperature and humidity of the greenhouse. The so-called forced ventilation is to force the air convection in the greenhouse by starting fans and so on, so as to adjust the temperature and humidity in the greenhouse. The two ventilation modes have their own characteristics and are suitable for different scenes.
  为了完成自然通风,人们可以在温室的侧壁或屋顶上安装窗户。 通常,温室的侧窗有利于增加温室周围的通风,但是开放区域有限。 温室天窗的开阔面积更大,并且热风不断上升,因此温室天窗可以更有效地增加整个温室的通风量,有利于促进整个温室的均匀降温。
  In order to achieve natural ventilation, people can install windows on the side wall or roof of the greenhouse. Generally, the side window of greenhouse is beneficial to increase the ventilation around the greenhouse, but the open area is limited. The open area of greenhouse skylight is larger, and the hot wind is rising, so the skylight can increase the ventilation of the whole greenhouse more effectively, which is conducive to promoting the uniform cooling of the whole greenhouse.
  随着单个温室面积的不断扩大,就改善温室通风而言,天窗比侧窗要好得多。 借助开窗系统,可以根据需要打开或关闭温室的侧窗和天窗。 温室的侧窗通常是连接窗。 如果温室覆盖相对坚硬的材料,例如玻璃和PC板,则由连续的齿条齿轮系统驱动。 如果是软质材料(例如薄膜),则可以选择卷卷窗系统。 另一种选择是使用可充气的窗户,该窗户可对气囊充气或放气以完成窗户的关闭和打开。 可以计划将温室天窗沿着温室的屋顶间歇地打开和打开。 如果连接到天窗,则由连续的齿条齿轮系统驱动,每个天窗都使用连续的齿条齿轮系统。 多个连续的天窗也可以与分开的齿条和小齿轮系统一起打开和关闭,也就是说,车窗轴上的扭矩分配器连接到蜗轮减速器的输入轴上,而蜗轮减速器则驱动天窗。  。 当天窗数据是胶片时,您也可以使用胶片打开窗口系统; 如果是破损的天窗,则可以选择桁架式齿轮系统,摇摆式齿轮系统和立柱固定式齿轮系统中的一种。 驱动系统。 同时,桁架齿条系统是常见的,摆动齿条系统很少使用,立柱固定齿条系统仅将桁架齿条系统中的驱动轴和齿轮移下侧 遮挡系统遮挡了入射光,这是开窗系统的发展趋势。

  With the continuous expansion of the area of a single greenhouse, the skylight is much better than the side window in terms of improving greenhouse ventilation. With the window opening system, the side windows and skylights of the greenhouse can be opened or closed as required. The side window of a greenhouse is usually a connecting window. If the greenhouse is covered with relatively hard materials, such as glass and PC board, it is driven by a continuous rack and pinion system. If it is a soft material (such as film), you can choose the rolling window system. Another option is to use an inflatable window that inflates or deflates the air bag to close and open the window. You can plan to open and open the greenhouse skylight intermittently along the roof of the greenhouse. If connected to a sunroof, it is driven by a continuous rack and pinion system, which is used for each sunroof. Multiple continuous skylights can also be opened and closed together with separate rack and pinion systems, that is, the torque distributor on the window shaft is connected to the input shaft of the worm gear reducer, which drives the skylight. When the skylight data is film, you can also use film to open the window system; if the skylight is damaged, you can choose one of truss gear system, swing gear system and column fixed gear system. Drive system. At the same time, the truss rack system is the most common, the swing rack system is rarely used, the column fixed rack system only moves the drive shaft and gear in the truss rack system to the lower side to block the incident light, which is the development trend of the window system.
  温室强制通风系统通常使用低压大流量轴流风扇或循环风扇。 低压大流量轴流风扇主要用于将空气吹入温室,并且可以在温室外通风。 温室外的通风可以避免气流对温室中植物的伤害,通过温室中的缝隙可以补偿温室中的室外空气,有利于在温室中形成均匀适度的气流场。 应用范围更广。  。 循环电流风机是小流量轴流风机,用于促进温室中的空气活动,有利于温室中温度和湿度的均匀化,并促进植物叶片水分的蒸腾作用。 当温室规模超过低压大流量轴流风机的有效工作距离时,可以将循环风机用作继电风扇,以确保强制通风的效果。
  The forced ventilation system of greenhouse usually uses low pressure and large flow axial fan or circulation fan. Low pressure and large flow axial fan is mainly used to blow air into the greenhouse, and can ventilate outside the greenhouse. The ventilation outside the greenhouse can avoid the damage of air flow to the plants in the greenhouse. Through the gap in the greenhouse, the outdoor air in the greenhouse can be compensated, which is conducive to the formation of a uniform and moderate air flow field in the greenhouse. It has a wider range of applications. The circulating current fan is a small flow axial flow fan, which is used to promote the air activity in the greenhouse, to facilitate the homogenization of temperature and humidity in the greenhouse, and to promote the transpiration of plant leaf water. When the scale of greenhouse exceeds the effective working distance of low pressure and large flow axial-flow fan, the circulating fan can be used as relay fan to ensure the effect of forced ventilation.
