Presents the principle of chilled water producing technology y indirect evaporative cooling, test ing perform ances of the unit developed and actual application ef fects. Reviews the applications of this technology at present and prospects in the future. The outlet temperature of indirect evaporative w ater chiller units is 16 t o 19 ! , reaching the average value of local outdoor w et ul temperature and dewpoint temperature, and can e used as the cold source. The indirect evaporative chiller and its system have een prom oted to a larger extent in northw est China. Keywords indirect evaporative w ater chiller, dry air, dewpoint temperature
