Dimensionering av klimatsystem vid Hietalas växthus i Övertorneå.
The Hietala Greenhouse is used for cucumber production at the Polar Circle in Sweden. The problem was that the greenhouse temperature varied too much over the day (50C) and that the humidity fell out because of low night temperatures. The suggested system solves this problem by extraction hot humid...
