ABSTRACT:
A method of utilizing an economizer to reduce the energy usage of a mechanical refrigeration system. The method comprises the steps of: economizing if both cooling demand and the prerequisites to economize are present; measuring economizer capacity; determining if the measured economizer capacity is sufficient to meet the needs of a zone being conditioned; continuing to economize as long as there is both a cooling demand and the prerequisites to economize; and initiating the use of the mechanical cooling system only if the economizer capacity has been determined to be insufficient to meet the needs of the zone being conditioned.
