Description

Attached-greenhouse gravity-flow ventilation and force ventilation dual purpose system
Technical field
The present invention relates to a kind of apparatus system of attached-greenhouse ventilating system, relate in particular to a kind of attached-greenhouse gravity-flow ventilation and force ventilation dual purpose system.
Background technology
At present, known attached-greenhouse ventilating system is to adopt gravity-flow ventilation or force ventilation mode, only selects wherein a kind of draft type of configuration in actual production is used, and these two kinds of draft types do not have both simultaneously in the greenhouse system.
Adopting gravity-flow ventilation, is the principle of utilizing blast and hot pressing, under many weather conditions, when windy or temperature is not too high as the external world, can reach ventilation effect preferably, and operating cost is low at ordinary times for it, and is easy to maintenance.But be subject to the restriction of conditions such as extraneous natural climate condition influence and effective ventilation distance in using, under hot climate, performance of ventilating does not reach production requirement especially.
The pressure forced air that force ventilation relies on blower fan to produce flows in the greenhouse.Its operational effect of force ventilation is good, and ventilation is guaranteed, is not subjected to extraneous weather influence substantially, can satisfy the air-conditioning requirement of the long distance of large greenhouse.But force ventilation causes short circuit because of leaking out when preventing exhausting, requires the greenhouse seal better, easily so innerly in the greenhouse forms long-pending heat, increase the ventilation operating load, and day-to-day operation is very big to the electric power dependence, and the overall operation cost is higher relatively.
Conventional gravity-flow ventilation adopts the volume film to window or the pivot frame of rack-and-pinion transmission, and the volume film is windowed and is generally used for plastic greenhouse, and its aperture of windowing is bigger, but sealing is difficult for guaranteeing, is difficult to and the supporting use of mechanical ventilation system.Pivot frame formula vent window reaches the purpose of hermetically closing by the tooth bar push-tight forms of mechanism driving, and its sealing is guaranteed, but aperture is less, and opening angle is no more than 45 degree usually, and agency cost is higher relatively, and overall drafting efficiency is relatively poor.
Gravity-flow ventilation operating cost is low, but is difficult for the long-time performance of ventilating that guarantees; The force ventilation performance can satisfy the production instructions for use, but operation for a long time, its operating cost is higher.Function how to gather gravity-flow ventilation and force ventilation, the greenhouse dual-purpose ventilating system that reaches mutual supplement with each other's advantages is still blank so far at home.
Summary of the invention
