VENTILATION METHODOLOGIES IN GREENHOUSES

A. NICOLAUS
The symposium title indicates that in the first place simple ventilation methods are concerned. In fact the most simple method with regart to climate regulation is mechanical ventilation fully automatically controlled and operated both on air temperature, air humidity and even air quality. A more complicated method of ventilation probably is natural ventilation but fully automatically controlled. Even more complicated is natural ventilation semi-automatically controlled (e.g. roof vents operated automatically and side vents manually opened) or full manually controlled.

In the context of the symposium simple methologies need to be interpreted as the study of inexpensive but reliable solutions based on natural ventilation effects and even manually controlled.

In fact the design of any ventilation system undoubtly must be based on a number of criteria:

  1. climate parameters with accent on insolation, temperature, wind influences,
  2. design of the greenhouse : geometrics and dimensions, orientation and locally inplantation,
  3. design of the proper ventilation systems of the house implying the study of the vent surface, the spreading of the vent surface over the construction and the control of the vent system.

In the paper only general information and indications as introductory statements are dealt with. More practical results certainly will be given in the different contributions and also presented during the poster session.
