Currently, high heating cost in greenhouses is a main drawback for their widely use.
The heating cost has the highest percentage of the total production cost. In this
research, in order to reduce the heating cost four greenhouses which are 36 m2 were
constructed. One of these greenhouses had a fixed volume while the others were
reduced by 10%, 20% and 30% (variable vertically). The effect of variable volume
on the temperature, relative humidity and fuel economy in the greenhouse was
investigated.
Two different experiment periods showed that volume control affected temperature,
relative humidity and fuel need in the greenhouses. In the greenhouse reduced
volume 30%, temperature increased 9%, relative humidity reduced %12 and fuel
need reduced 24% according to traditional greenhouse.
