Fan And Pad Greenhouse Evaporative Cooling Systems
The 4 or 6 inch thick pad is treated with anti rot salts stiffening and wetting.
Fan and pad greenhouse evaporative cooling systems. Huifa cooling fans offer high volume output and smooth operation powered by a high efficiency motor. Experience has shown that air may heat up as rapidly as 1 f every 10 feet as it moves across the greenhouse on sunny summer days. 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 greenhouse evaporative cooling systems 3 area covered by plants and floor material i e bare soil or concrete.
It contains a cellulose pad overhead water supply pipe gutter to collect excess water a sump tank pump piping and control. Evaporative cooling is the process of having particles of water evaporate which leads to a drop in temperature through increased humidity. Designed with the grower in mind these cooling pads and systems will use heat in the air to evaporate water from plants and other wetted surfaces that will then cool your structure. The basis of any evaporative cooling system is the evaporation of water into an airstream.
The fan and pad system has been the standard system for evaporative cooling for more than 50 years. The most common way of accomplishing evaporative cooling in a greenhouse is with a fan and pad system figure 1. The roof configuration can also influence the temperature increase. In this system aspen or cellulose pads are mounted in one endwall or sidewall of the greenhouse.
Several evaporative cooling systems work well in commercial greenhouses. Evaporative cooling is a tool that can be used to reduce greenhouse temperatures. Cooling fans and cooling pads. Cooling pads cool by creating large amounts of.
A fan and pad system uses exhaust fans to pull air through evaporative cooling pads. There are two systems which use this principle in commercial greenhouses. Note that swamp coolers can be considered stand alone evaporative cooling systems but otherwise operate similarly as pad and fan systems. Pad and fan systems are part of a greenhouse s mechanical ventilation system.
The most common is the fan and pad system. Evaporative cooling system consists of 2 main parts. The preferred cooling method for a greenhouse is through evaporative cooling. The slower the air.
This technique utilizes the cooling effect produced when water evaporates and cools the air as it is pulled through the pad. High pressure fogging and the pad fan cooling system. Two evaporative cooling systems are commonly used in greenhouses. Fan and pad system.
Its main purpose is to promote indoor ventilation and cool down the temperature in the greenhouse. Square box design for easy installation. Evaporative cooling achieve and maintain cooler temperatures in your greenhouse in any climate with a cost effective evaporative cooling system.
