ENERGY SAVING AND CLIMATE CONTROL IN GREENHOUSES WITH CONCERTINA SHAPED SCREENS, MADE OF METALLIZED COMPLEX FILM

Th.F.M. Lommerse
The application of screens changes the greenhouse climate. Supported by scientific research, there is a growing awareness of the possbility of improving the greenhouse climate by means of a screen.

This development requires a screen and a screen installation which provides high energy savings, little light loss and climate control possibilities.

The objective of this project is to prove that with a concertina shaped screen with a closed metallized structure, all these effects can be achieved.

Provisional conclusions:

  • overall light transmission in the greenhouse reduced by concertina screen and screen installation from 68 to 65%.
  • energy savings with a closed screen circa 60%
  • by utilising small screen openings, the relative humidity can be controlled.
  • although small screen openings are used to control the climate, there is still a saving of energy.
  • side screens ensure uniform temperature.
