ABSTRACT
The article focuses on the control of primary-only- (P-only) plant at same level with the primary/secondary- (P/S-) plant operating at low-load delta-T conditions. It illustrates the performance of P-only-plant with minimum chillers on and controlled for the maintenance of acceptable evaporator velocities. It explains that P/S plant with water temperature entering the air-handler-coil control does better than the P-only plant equipped with minimum towers/chillers.
