Why is air introduced into the greenhouse through a tube in the winter cooling system?
What will be an ideal response?
Incoming air can be colder than the desired inside temperature. To
prevent cold spots in the plant zone, incoming air exits from holes along the sides
of the tube in turbulent streams such that it mixes with warmer greenhouse air
before reaching the plants.
