Résumé

Air-cooled chillers are generally the major electricity consumers in air-conditioned buildings in the subtropical climate. This paper presents how the COP of these chillers can be improved by modulating heat rejection airflow via variable speed condenser fans. The set point of condensing temperature was used to determine the number and speed of condenser fans staged in various operating conditions. It was found that adjusting the set point in response to the outdoor temperature alone cannot achieve maximum COP when using variable speed condenser fans.
