ANSI ARI-410-2001 pdf download FORCED-CIRCULATION AIR-COOLING AND AIR-HEATING COILS
3.3.1 Forced-Circulation Air-Cooling Coil. A heat exchanger, with or without extended surfaces, through which either cold water, cold aqueous ethylene glycol solution or volatile refrigerant is circulated, for the purpose of total cooling (sensible cooling plus latent cooling) of a forced-circulation air stream.
3.3.2 Forced-Circulation Air-Heating Coil. A heat exchanger, with or without extended surfaces, through which either hot water, hot aqueous ethylene glycol solution or steam is circulated for the purpose of sensible heating of a forced-circulation air stream.
3.4 Heating Capacity. The capacity associated with the change in dry-bulb temperature expressed in Btu/h [W].
3.5 Laboratory Tests. Tests conducted by a manufacturer on representative coils to determine basic heat transfer and pressure drop characteristics that shall be used in developing Published Ratings.
3.6 Published Ratings . A compilation of the assigned values of those performance characteristics, under stated rating conditions, by which a coil may be chosen to fit its application. These values apply to all coils of like nominal size and type (identification) produced by the same manufacturer. As used herein, the term Published Ratings includes the ratings of all performance characteristics published in specifications, advertising or other literature controlled by the manufacturer or available through an automated rating/selection computer procedure.
3.6.1 Application Ratings. Ratings determined at conditions outside the range of standard rating conditions.
3.6.2 Standard Ratings. Ratings within the range of standard rating conditions (Table 1) and which are accurate representations of test data.
3.7 “Shall” or “Should”. Shall or “should” shall be interpreted as follows:
3.7.1 Shall. Where “shall” or “shall not” is used for a provision specified, that provision is mandatory if compliance with the standard is claimed.
3.7.2 Should. “Should” is used to indicate provisions which are not mandatory but which are desirable as good practice.
3.8 Standard Air. Air weighing 0.075 lb/ft 3 [1.2 kg/m 3 ] which approximates dry air at 70 °F [21°C] and at a barometric pressure of 29.92 in Hg [101.3 kPa].
3.9 Standard Coil Orientation. The standard coil position is that of horizontal tubes and vertical coil face with horizontal airflow.
3.10 Test Series. A group of related tests performed on the same test coil.
3.11 Turbulators. Mechanical devices inside tubes used to increase turbulence of fluids.
