Claim One:
1. A method for predicting the performance of a chiller in real time over a range of refrigeration loads as a function of entering condenser water temperature and total rejected heat comprising; a. providing a first means for measuring entering condenser water temperature, b. providing a second means for measuring leaving condenser water temperature, c. calculating total rejected heat from the chiller into the leaving condenser water as a function of a fixed condenser water flow rate and the difference between the entering condenser water temperature and the leaving condenser water temperature, d. providing a third means to determine maximum feasible refrigerant flow from the chiller refrigerant condenser to the chiller refrigerant evaporator at any load and any entering condenser water temperature, e. providing a formula for calculating a predicted refrigeration load of the chiller as a function of total rejected heat from the chiller and the entering condenser water temperature.
