  • Page 41: Demand Limit

    Under normal operation, the chiller will maintain a constant leaving fluid temperature approximately equal to the chilled fluid set point. As the cooler load varies, the entering cooler fluid will change in proportion to the load as shown in Fig. 27. Usually the chiller size and leaving-fluid temperature set point are selected based on a full-load condition.
