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 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.
A dual fan design guarantees an advanced heat dissipation.
You can even rest the cooling pad on a pillow or comforter without bothering about overheating.
This technique utilizes the cooling effect produced when water evaporates and cools the air as it is pulled through the pad.
Dual intake vents and a curved architecture concede to use your laptop on both hard and soft surfaces.
The fans exhaust air from the greehnouse and draw in fresh air through the pads.
A fan and pad system uses exhaust fans to pull air through evaporative cooling pads.
The most common is the fan and pad system.
Cooling pads cool by creating large amounts of surface area that are exposed to air being drawn into the greenhouse by exhaust fans.
Evaporative cooling pads are 4 to 6 inches thick 12 inches wide with height increments every 12 inches from 24 to 96 inches.
They are supplied with water from a pipe above the pads and excess water is collected in a gutter at the bottom.
In this system aspen or cellulose pads are mounted in one endwall or sidewall of the greenhouse.
It contains a cellulose pad overhead water supply pipe gutter to collect excess water a sump tank pump piping and control.
Several evaporative cooling systems work well in commercial greenhouses.
For the evaporative cooling system ensure that the evap pads are positioned adjacent to each other to form a continuous pad of the required.
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.

With this type of system exhaust fans are placed in one wall of the greenhouse and pads are in the opposite wall.
