The American Society of Heating Refrigeration and Air-Conditioning Engineers (ASHRAE) has developed standards that the industry uses to test their Terminal units (ASHRAE Standard 130) and Fan Coils (ASHRAE Standard 79). These documents outline the standard procedure for testing each piece of equipment. Standard 130 outlines terminal unit pressure drop and sound testing, while Standard 79 covers fan coil airflow and cooling/heating capacity testing. Nailor performance data published in our selection software and catalogs are based on these standards. ...
