Hybrid Indirect Evaporative Air Cooler uses advantage of cooling using water evaporation without increasing humidity of supply air. It helps in reducing dry bulb temperature and enables its use in all climate zones. This hybrid cooler couples conventional mechanical cooling with evaporative cooling techniques that helps to reduces compressor electricity demand and consumption. Its each component can operate independently or simultaneously, according to ambient conditions and cooling demands. In indirect method, air is passed over water coils to pass heat from air to water. Hybrid Indirect Evaporative Air Cooler is highly efficient and excellent quality cooler suitable for use in scorching summers.
Working flow is divided into many small flows which pass the dry channels in the lower part of the cooling core. Every small flow is cooled by all the small flows before it crosses pass in another side channels called "wet channels".
Dry and wet channels are placed one by one with thinner wall separately made of special materials. Heat transfers but no water exchanges. Working flows are cooled down but no moisture added. Then every flow goes into wet channels placed its two sides by through its controlling holes, contact with the counter-flow water. It is cooled and moisture added. Then bring the heat passed from its two-side. Its temperature is lowed down continuously at the end; its temperature goes under the web-bulb of its beginning flow, near the dew-point temperature.
Supplying flow also is divided into many small flows, go through the dry channels placed in the part of the core. They are cooled by their own two-side working flows crossing flow in the wet channels. No any moisture is added, but the temperature is cooled down under the wet-bulb of its beginning flow.
