During summer periods, high temperature values that are
being formed in greenhouses can greatly influence the
efficiency of production workers and also decrease the
productivity of plants grown there. A greenhouse production
without the cooling systems can be sustained at the
desirable level by imposing summer restrictions in the areas
with warm climate, and by starting cooling in the areas with
cold climate. A statement can be made regarding both utility
and efficiency of fan-pad cooling systems that they tend to
go up in the areas with low relative air humidity. The
present study has been carried out in order to either prove
or disprove this statement. We have attempted to create a
map of internal greenhouse temperature distribution via
determining the system’s efficiency. As a result of this
study, it was determined that since air temperature and
relative humidity in the air tend to decrease during summer
months by using fan-pad cooling system, temperatures in the
greenhouse can be consequently lowered down to 10-12°C.
Statistical analysis revealed remarkable differences
(p<0.01) between the temperatures at various points in
greenhouses observed.
