DESCRIPTION

  • This is a Polyhouse Fan Pad System. This system can be deployed on plain ground.
  •  A Polyhouse typically made from G.I. and covered in polyethene.
  •  For structure, this system has the following main parts are G.I. Truss, truss supports & Columns.
  •  The system consists of 14 G.I. Truss & truss supports as well as 21 Columns. On one side of the structure having Cellulose Pads (Honeycomb Structure) and on the opposite side two fan units of 1.1 KW AC motors.for cooling of pads water delivered through the distridution pipe.

size

  • Total area required: (28 m*16.12 m) = 451.36 mtr2 = 4858.40 sq.feet.

CONSTRUCTION

  • A polyhouse is a specially constructed structure like a building for growing plants under controlled conditions.
  •  It is covered with a transparent material like     polyethene as such permits the entry of natural light.
  •  polyhouse is covered hence it provides protection to crop from harmful UV rays, excessive rainfall, frost and pests.

working

  • In this system, Cooling pads are mounted in one end wall or sidewall of the Polyhouse.
  •  They are supplied with water from a pipe above the pads and excess water is collected in a gutter at the bottom.
  • Air drawn through the wet pads by slow axial fans mounted in the opposite end wall or sidewall is saturated and cools the greenhouse.
