Fan And Pad Evaporative Cooling System Has Been Available Since

The basis of any evaporative cooling system is the evapora tion of water into an airstream.

Fan and pad evaporative cooling system has been available since. Pad and fan systems are part of a greenhouse s mechanical ventilation system. 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. Rating is available when the video has been rented. They are supplied with water from a pipe above the pads and excess water is collected in a gutter at the bottom.

These fog systems can be designed and operated to. 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. Glacier cor systemcall to order.

In order to obtain better results the relative distance between cooling pad and fans of the green house should be not more than 50mtrs. Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles. Greenhouse tunnel pad fan humcontrol hd duration. Fan and pad system is comprised of three main equipment circulation pumps exhaust fan and evaporative pad.

We fabricate qualitative range of fan pad evaporative cooling system. An exhaust fan is fitted on one side of the greenhouse wall while a wetted. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate. For the evaporative cooling system ensure that the evap pads are positioned adjacent to each other to form a continuous pad of the required height and length.

Typical fan and pad greenhouse arrangement. 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. Note that swamp coolers can be considered stand alone evaporative cooling systems but otherwise operate similarly as pad and fan systems. The coolest area of the greenhouse is adjacent to the evaporative cooling pads.

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. The fan and pad system has been the standard system for evaporative cooling for more than 50 years. 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. High pressure fog systems are also used to cool green houses.
