Heat requirement of greenhouse, calculated according
to the principles specified in DIN EN 13032 (formerly DIN 4701) standards,
depends on the type of greenhouse, the equipment, climate condition of
greenhouse location, and the optimum growth temperature of plants. The heat
requirement calculations are usually performed using mean values of daily
temperature. However, calculations based on daily average temperature values
shows difference from actual values. Determination of optimal heat consumption
values in greenhouse were observed when hourly climate values (temperature,
solar radiation, and wind) were used.
Also, the heat requirement of greenhouses depends on
the greenhouse equipments. The type of used heating systems, type of heat
curtains used for heat saving and their leaks affect the heat requirement.
During the day heat energy was stored and causes temperature increasing in
greenhouse. The ISIGER-SERA expert system model calculates the heat requirement
in the greenhouse taking into account all these effects mentioned. In this
study, it is aimed to test the ISIGER-SERA expert system model in high
technology established producer greenhouse located Mediterranean climate zone
(Adana). Results showed that only 3% differences were observed between calculated
heat energy requirement with ISIGER-SERA expert system model and the actual
consumed heat energy in greenhouse.
Serada ısı
gereksinimi, seranın tipine, donanımına, sera kurulacak yerin iklimine ve
bitkilerin arzu ettiği sıcaklığa bağlıdır ve DIN EN 13032 (Eskiden DIN 4701)
standartlarında belirtilen esaslara göre hesaplanmaktadır. Seralarda ısı
gereksinim hesaplamaları daha çok günlük ortalama sıcaklık değerlerinden
gidilerek yapılmaktadır. Ancak günlük ortalama sıcaklık değerlerine göre
yapılan hesaplamalar gerçek değerlerden farklılıklar göstermektedirler.
Seralarda ısı tüketiminin belirlenmesinde en sağlıklı değerler saatlik iklim
değerlerinden (sıcaklık, güneş radyasyonu ve rüzgâr) gidilerek yapılan
hesaplamalarla elde edilmektedir.
