A greenhouse is a plastic or glass structure that can provide a
suitable micro-climate for various crops and plants, protecting
them from severe and variable outdoor weather conditions. During
the daytime with intense solar radiation, the greenhouse effect
caused by the absorption of solar radiation makes the temperature
inside the greenhouse even higher than the ambient temperature;
thus, plants and crops may suffer being dried due to high rate
of evapotranspiration caused by the excessive heat, and their
production may decline. To provide a suitable growing environment,
cooling technologies are essential and must be introduced.
It plays a vital role in the greenhouse industry especially in hot
weather although it is still important in any other climate
conditions
