This standard applies to factory-made@ forced-circulation free-delivery unit coolers operating with a volatile refrigerant fed by either direct expansion or liquid overfeed at wet and/or dry conditions. This standard does not include the following: a. Air conditioning units used primarily for comfort cooling for which testing methods are given in other standards b. Unit coolers operating at latent load conditions with a refrigerant saturation temperature of less than 32??(0.0?? c. Unit coolers installed in or connected to ductwork or with external air resistance devices not provided by the manufacturer d. Unit coolers using zeotropic refrigerants with glides greater than 12.6??(7.0?? e. Field testing of unit coolers PURPOSE This standard establishes uniform methods of testing for obtaining performance data@ lists and defines the terms used in testing@ specifies data to be recorded and formulas to be used in calculations@ and sets limits and tolerances in testing.
