Method of Test for Indirect Evaporative Air Coolers
Provides laboratory test procedures and calculations for establishing the cooling capacities and power requirements for indirect evaporative air-cooling equipment. Applies to testing indirect evaporative air coolers operating at steady-state conditions that a) Sensibly cool a primary airstream through heat exchanger(s) by the evaporation of water into a secondary airstream and b) Are packaged systems or are components of packaged systems. This standard does not apply to a) Devices that use mechanical refrigeration or thermal storage to cool the primary airstream, the secondary airstream, or the water provided for evaporation during the test or b) Devices that dry the primary or secondary airstream during the test. Dual units of measurement.
