How to ventilate the large glass greenhouse

The glass greenhouse is a kind of greenhouse that is entirely made of glass as the covering material. The common glass greenhouse has a size of one to two to three to five thousand square meters, but there are also glass greenhouses with a large single building area that can reach a single 100,000 square meters, so how can such a large area of glass greenhouses be ventilated and cooled? Let's take a look together here.

1. Natural ventilation at the top to cool down

The principle of natural ventilation at the top is to use the principle of hot air floating up and cold air sinking. The top of the patterned greenhouse is arranged in a small triangle arrangement. On one or both sides of the spire, windows are arranged, and then the motor drive system can be used. Open and close windows. The proportion of the number of ventilation windows and the opening angle of the ventilation windows will affect the ventilation efficiency. The natural ventilation system can fully meet the planting needs in spring, autumn and winter in the greenhouse planting.

2. High pressure spray system

High-pressure atomization equipment refers to a system that uses a high-pressure atomization host to transport the water after precision filtration to a special high-pressure pipe network for fog generation (pressure resistance 14 MPa), and finally spray it into a mist by a special spray nozzle for fog generation. The working principle of the high-pressure atomization system is that high-pressure water is sprayed from the micro-holes and collides with solids to form water mist. The pressurized water (greater than 4 Mpa) is atomized by a professional nozzle through a high-pressure transmission pipeline to produce 0.10-15.00 um micro-mist particles, which can quickly absorb heat from the air to complete vaporization and diffusion, thereby achieving The purpose of air humidification and cooling.

3. Priority Corridor

The ventilation corridor is used to cool the outdoor air through the water curtain and enter the corridor, and then the positive pressure blower is used to transport it to the inside of the greenhouse through the air supply belt, which solves the problem of the short suction distance of the positive pressure fan water curtain.
