Airflow 2000m3/h Inter-cross Dew Point Indirect Evaporative Air Cooler
Airflow 2000m3/h Inter-cross dew point indirect evaporative air cooler
AJL10-DJ20A
Means serial No. A dew point indirect evaporative air cooler units with nominal cooling capacity 10kw,nominal airflow 2000m3/h,structure type:combined
Marks: standard working conditions for cooling performance
dry bulb temperature 38°C
wet bulb temperature 23°C
Working Principle
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 al the small flows before it crossing 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.
Features
1)High efficiency,COP reach to over 30
2) Comfortable:cool but no moisture added
3) System can work well in 50 environment,and with ambient temperature rises, the cooling ability will increase
4) The supplying air temperature reach to web bulb temperature
6) Easy maintenance
7) Intelligent control:Take central controller to auto adjust the airflow,can be used separately in dry
8) Group control
9) Environment friendly
