Fan and pad evaporative cooling system has been available since.

In this system aspen or cellulose pads are mounted in one endwall or sidewall of the greenhouse. The coolest area of the greenhouse is adjacent to the evaporative cooling pads. 330 302 4203evaporative cooling pads are 4 to 6 inches thick 12 inches wide with height increments every 12 inches from 24 to 96 inches. Two evaporative cooling systems are commonly used in greenhouses.

The basis of any evaporative cooling system is the evapora tion of water into an airstream. 2 1 1 fan pad system the fan pad evaporative cooling has been applied since 1954 and is still the most common system in greenhouses during summer purohit 2012. An evaporative cooler also swamp cooler swamp box desert cooler and wet air cooler is a device that cools air through the evaporation of water. These fog systems can be designed and operated to.

Typical fan and pad greenhouse arrangement. It is used to cool the air by using the heat present in the air and evaporate the water from an adjacent surface of the pad. Note that swamp coolers can be considered stand alone evaporative cooling systems but otherwise operate similarly as pad and fan systems. We fabricate qualitative range of fan pad evaporative cooling system.

As this cooled air moves along the width of the greenhouse it sucks up heat so that the exhaust air is warmer than the inlet air. In order to obtain better results the relative distance between cooling pad and fans of the green house should be not more than 50mtrs. Fan and pad system is comprised of three main equipment circulation pumps exhaust fan and evaporative pad. Rating is available when the video has been rented.

The most common way of accomplishing evaporative cooling in a greenhouse is with a fan and pad system figure 1. Evaporative cooling with this new pad cooling system editado duration. High pressure fog systems are also used to cool green houses. Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles.

An exhaust fan is fitted on one side of the greenhouse wall while a wetted. They are supplied with water from a pipe above the pads and excess water is collected in a gutter at the bottom. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate. Pad and fan systems are part of a greenhouse s mechanical ventilation system.
