HOW TO USE FORCED VENTILATION TO REDUCE TEMPERATURE
Being able to control the temperature inside a greenhouse during the summer months is a challenge and to achieve this, the use of ventilation is essential.
If we look at the way in which air is renewed between indoors and outdoors, there are two types of ventilation in a greenhouse.
- Passive or natural ventilation. This is generated through the zenithal and lateral windows, through which the natural wind enters and renews the air inside.
- Forced or mechanical ventilation. That which, using a series of fans and cooling panels (cooling system), actively controls the temperature and humidity.
Although natural ventilation has traditionally been used more than forced ventilation due to its low cost, in times of high temperatures and in regions with low relative humidity, forced ventilation through the cooling system has proven to be one of the most reliable and efficient ways to reduce the temperature inside the greenhouse.
The main advantages of these cooling systems are that they manage to reduce the temperature in each of the compartments to be air- conditioned, providing the ideal temperature conditions for cultivation and, in addition, they renew the air inside and outside.
With Nutricontrol’s climate control units it is possible to control forced ventilation or cooling. The units are able to control the different stages of the fans and also control the air intake and the evaporative panel pump of the cooling systems.
