These two are inseparable! In this four-hour seminar and lab attendees will review and cover the two necessary steps to properly commission a running system. Techniques for airflow evaluation will be reviewed along with interpreting blower performance charts. This seminar will also cover how airflow affects the overall system, airflow measurement methods, common mistakes made during repairs, proper startup, and service methods.  Then once the air side is confirmed, establishing the correct charge will be covered. Superheat, subcooling target acquisition, and charge evaluation will finish with demonstrations of working equipment and testing devices.
