The air that leaves the pad is therefore cooled and humidified simultaneously without any external energy supply for the evaporation process.
The heat that is needed for the evaporation is taken from the air itself. Although evaporative cooling is most effective in dryer climates, such as suitable for North, Central and west part of India. Slow water contamination and efficient water flow, to achieve temperature 10-12oC +2 oC below ambient temperature 45% RH.Įvaporative cooling, which uses the heat in the air to evaporate water from plants and other wetted surfaces can be used to cool the greenhouse as much as 10 to 12oC below the outside temperature. Even water delivery through distribution pipe will be ensured. Hi Tech Poly House with Celdak Cellulose Pads (Sweden make) to acquire proper CFM of air movement per sq.ft of area will be provided. It can be used for many different cooling purposes but is particularly suitable for cooling of greenhouses where higher air velocity is required. Hi Tech Poly House with fan and pad controlled is used in those systems where high efficiency cooling is required. Air drawn through the wet pads by slow axial fans mounted in the opposite end wall or sidewall is saturated and cools the greenhouse. 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, Cooling pads are mounted in one end wall or sidewall of the Polyhouse. Two temperatures are essential when dealing with evaporative cooling systems.Hi Tech Poly House with fan and pad controlled. As water evaporates, energy is lost from the air causing the temperature drop. It reduces air temperature by evaporation of water into the airstream. The system uses an aluminum frame, a beautiful shape, border, heat distortion is small.Ĭooling fans and cooling pads utilize evaporative cooling. When the outdoor air is sucked vacuum chamber at a constant speed through the gap from the cooling pad, leading to water evaporation, cooling, cool air flows through the greenhouse, interior heat absorbed by the exhaust fan, so as to achieve the purpose of cooling. Cleaning solution for fogging systems: Turn off exhaust fans Wet pads. Say that your greenhouse has a length of 100 ft. The following will serve as an example for designing a pad cooling system for a gutter-connected greenhouse. When you need to cool down, start the fan, air is forced out of the greenhouse, resulting in negative pressure at the same time, the pump will hit the water across the cooling pad wall. Cool-N-Klean is labeled for evaporative cooling pads and approved by pad manufacturers. The ambient air as it passes through the wet pads cools down close to wet bulb temperature. Order Cooling Equipment online at our Greenhouse Megastore or call 1-88 to order from a Sales. We also supply replacement Glacier-Cor pads and Aspen pads as well as pumps and plumbing for Evap Pad Systems. The fan is equipped with light deprivation hood to prevent light goes inside through cooling fans.Ĭooling pad installed in the northern end of the greenhouse, greenhouse fan mounted in the southern end. International Greenhouse Company has everything you need to build a complete Glacier-Cor Evaporative Cooling System (wet wall). Its main purpose is to promote indoor ventilation and cool down the temperature in the greenhouse. Huifa Cooling fans offer high volume output and smooth operation powered by a high-efficiency motor. Evaporative cooling system consists of 2 main parts cooling fans and cooling pads.
