Fan And Pad Cooling System

A fan and pad system uses exhaust fans to pull air through evaporative cooling pads.

Fan and pad cooling system.

In this system aspen or cellulose pads are mounted in one endwall or sidewall of the greenhouse. For the evaporative cooling system ensure that the evap pads are positioned adjacent to each other to form a continuous pad of the required. You can even rest the cooling pad on a pillow or comforter without bothering about overheating. The 4 or 6 inch thick pad is treated with anti rot salts stiffening and wetting agents.

The fans exhaust air from the greehnouse and draw in fresh air through the pads. Several evaporative cooling systems work well in commercial greenhouses. The most commonly used evaporative cooling system used in greenhouses is the fan and pad evaporative cooling system see figures 5 5 and 5 6. Fan and pad evaporative cooling systems.

A dual fan design guarantees an advanced heat dissipation. They are supplied with water from a pipe above the pads and excess water is collected in a gutter at the bottom. The large fan provides efficient cooling for bigger laptops plus you also get rgb lighting around the edges of the pad with various different modes pulsing blinking or just static lighting of. With this type of system exhaust fans are placed in one wall of the greenhouse and pads are in the opposite wall.

This technique utilizes the cooling effect produced when water evaporates and cools the air as it is pulled through the pad. The fan and pad system has been the standard system for evaporative cooling for more than 50 years.

The most common is the fan and pad system. The system consists of a plastic cooling pad fcp 150 with a large evaporative element made of finely meshed polypropylene as well as a special deflector and a fancom controller. Evaporative cooling pads are 4 to 6 inches thick 12 inches wide with height increments every 12 inches from 24 to 96 inches. It contains a cellulose pad overhead water supply pipe gutter to collect excess water a sump tank pump piping and control.

For pad and fan systems an evaporative cooling pad is installed in the ventilation opening ensuring that all incoming ventilation air travels through the pads before it enters the greenhouse environment. The special deflector ensures that water is well distributed over the pad so the available cooling capacity is fully utilised.
