Discussion on some problems in establishing the standard of Commercial or industrial evaporative air-conditioners

With an analysis of typical meteorological year data in some representative cities in China’s dry areas and highly humid coastal areas, selects 38 ℃/23 ℃ as the dry bulb temperature and wet bulb temperature of the nominal condition in dry areas and 38 ℃/28 ℃ in coastal areas with high relative humidity. By an analysis obtains the calculation method of the cooling capacity of evaporative air-conditioners, and provides a reference for the determination of the cooling capacity, energy efficiency ratio and testing method.
