Ventilation system for pig farm

In the farm, the smell is always not so good, but there are great differences between the farms, among which the design of the ventilation system is more important.
The types of ventilation system are divided into natural ventilation mode, full mechanical negative pressure ventilation mode, combination mode of natural ventilation and mechanical ventilation, mechanical positive pressure ventilation mode.
Horizontal ventilation: in places where the summer is not very hot and the duration is not long, such as northeast China, Inner Mongolia and northeast Xinjiang, horizontal ventilation can be used, which is suitable for nursing houses and delivery houses, but not for fattening houses,
Longitudinal ventilation: cooling by fan and wet curtain. The calculation of the ventilation system should be based on the pig's body weight in order to obtain the best wind speed.
