Besant and Johnson (1995) describe commissioning run-around systems.
In addition to starting and controlling run-around systems, run -around systems for ventilation air energy exchange should be commissioned for performance over a range of ambient temperatures from cold to hot. That is commissioning a run-around system should take place over a duration of at least six months and perhaps one year. Similar evaluations should be done periodically after the initial commissioning to ensure that the performance has not declined.
