What are the advantages of bag duct in greenhouse?

Greenhouse planting technology has brought people rich fruits and vegetables, and temperature and humidity control is particularly important for greenhouse planting. Too high or too low temperature and humidity will affect production, even lead to pests and diseases, and directly affect output and income.

How to control the temperature of the greenhouse? At present, it is mainly regulated by ventilation and heating in China.

At present, greenhouse heating is mainly through sunshine during the day and heat preservation and covering at night. Because of the large temperature difference between winter and night, the traditional heat preservation effect is not obvious, which will cause unfavorable factors for the growth of vegetables. We need to provide uniform heating for the greenhouse to ensure the environmental temperature required for vegetable growth. Ensure the fruit maturity rate of vegetables. The main way to cool the greenhouse is to exchange air inside and outside the greenhouse by uncovering the film, and adjust the temperature in the greenhouse by ventilation. But the biggest disadvantage of this method is that it is time-consuming and laborious, which increases the workload of greenhouse managers. The traditional refrigeration and heating technology has some shortcomings, such as uneven heating and air supply, and the effect is not obvious. With the development of science and technology, greenhouse planting gradually introduces high technology to save time and cost.

Bag air duct is a central air conditioning terminal ventilation system woven from special functional fibers, which can replace the traditional iron air duct, glass fiber reinforced plastic air duct, phenolic air duct and so on. The air supply of bag duct is accurate and uniform. Through CFD software calculation, the air supply can be fan-shaped along the radial direction or axial direction of the pipeline, and the air supply direction and distance are accurate, which meets the technological requirements of the greenhouse. Moreover, the weight of the bag-type air duct is extremely light, which is per square meter 150-400g, and the load on the greenhouse skeleton can be ignored.
