Experimental Research on Outlet Water Temperature Characteristic of Indirect Evaporative Water Chiller

The water temperature of indirect evaporative water chiller was tested in summer,that is a real project in Xinjiang.In the test range,the results show that the outlet water temperature of indirect evaporative water chiller between wet bulb temperature and dew point temperature outdoor air,lower 2～3 ℃ than wet bulb temperature.The approximation degree(evaporative cooling of the unit type water temperature of output and outdoor temperature difference between the dew point),and a rising trend with the change of outdoor air condition.However,the difference between outlet water mean temperature of indirect evaporative water chiller and wet bulb temperature outdoor air(this difference value is defined as cold depth) relatively stable and changes in 2～3 ℃.Therefore the cold depth is relatively appropriate for the outlet water temperature characteristic of indirect evaporative water chiller.
