Air cooler is a type of a hydraulic cooler. In order to work smoothly some applications require cool air with no traces of humidity. In hydraulic systems, hydraulic coolers do this task. Hydraulic air coolers enable cool air in the hot regions; it is less the price of an air conditioner but works more efficiently than any other coolers. Hydraulic air cooler is very good option against air conditioner.Air coolers (also called swamp) are devices that cool air through the simple evaporation of water. They differ from refrigeration or absorption air conditioning, which use vapor-compression or absorption refrigeration cycles. In the united states, aircoolers are often called swamp coolers. Air washers and wet cooling towers utilize the same principles as aircoolers, but are optimized for purposes other than air cooling. Aircooling is especially well suited for climates where the air is hot and humidity is low. But aircooling and vapor-compression air conditioning are sometimes used in combination to yield optimal performance. Some aircoolers may also serve as humidifiers in the heating season. In moderate humidity locations there are many cost-effective uses for aircooling, in addition to their widespread use in dry climates. For example, industrial plants, commercial kitchens, laundries, dry cleaners, greenhouses and confinement farming (poultry ranches, hog, and dairy) all often employ aircooling. In highly humid climates, aircooling may have little thermal comfort benefit beyond the increased ventilation and air movement it provides. Direct evaporative cooling (open circuit) is used to lower the temperature of air by using latent heat of evaporation, changing water to vapor. In this process, the energy in the air does not change. Warm dry air is changed to cool moist air. Heat in the air is used to evaporate water. Indirect evaporative cooling (closed circuit) is similar to direct evaporative cooling, but uses some type of heat exchanger. The cooled moist air never comes in direct contact with the conditioned environment. Two-stage evaporative cooling, or indirect-direct. Traditional evaporative coolers use only a fraction of the energy of vapor-compression or absorption air conditioning systems. Unfortunately, except for in very dry climates, they may increase humidity to a level that makes occupants uncomfortable. Two-stage evaporative coolers do not produce humidity levels as high as that produced by traditional single-stage evaporative coolers. Advantages- less expensive to install- estimated cost for installation is 1/8 to 1/2 that of refrigerated air conditioning. Less expensive to operate- estimated cost of operation is 1/4 that of refrigerated air. Power consumption is limited to the fan and water pump vs. Compressors, pumps, and blowers. Ease of maintenance-the only two mechanical parts in most basic evaporative coolers are the fan motor and the water pump, both of which can be repaired for very little and often by a mechanically able homeowner. Ventilation air- the constant and high volumetric flow rate of air through the building reduces the age-of-air in the building dramatically. Evaporative cooling increases humidity which may improve the breath ability of the air.
