1. Top full window system
The top full-opening window is a U-shaped rack installed at the girder position of the patterned multi-span glass greenhouse. The window reduction motor works by rotating and connecting the drive shaft, and the drive shaft drives the U-shaped rack to slowly push the window open. And closed. The advantage of this kind of window opening method is that the roof is fully open for ventilation, dehumidification, and cooling effects. However, the wind resistance of the fully open roof is slightly worse. Be cautious in windy areas.2. Continuous staggered window opening system
The windows of the greenhouse are located on a slope of the spire, and the drive system is installed at the position of the bracket of the girder and works along the truss beam (span direction). When the window is opened, the geared motor drives the drive shaft in one direction by pushing the support rod fixed in the slideway of the window frame to work back and forth. The advantage of this kind of window opening method of the patterned glass multi-span greenhouse is that the windows can be opened according to their actual needs and the main local wind direction. This method of top opening is currently used in the greenhouse industry. A relatively broad method.
3.Side opening window system
Greenhouse window opening system refers to the equipment system that uses electricity or manpower in the greenhouse to open and close the top window or side window of the greenhouse through the window drive mechanism. This chapter mainly describes the sliding window system commonly used in modern greenhouses and relying on electric power. the design of. The greenhouse window system is mainly used for the natural ventilation of the greenhouse. Natural ventilation is very necessary for the use and planting of greenhouses. It can effectively regulate indoor air temperature, temperature and CO2 concentration to meet the needs of normal sound field requirements for indoor cultivated plants. Moreover, the investment cost of window system equipment required for natural ventilation is not High, operation and management costs are also very low, and the shading area is small, which does not hinder indoor production operations.
