Abstract
A method is provided for operating a refrigerant vapor compression system, for example an air-cooled chiller or air-cooled condensing unit, at optimal energy efficiency rating. The method includes the steps of: determining the instantaneous values of a plurality of selected operating parameters of the system's refrigeration unit, calculating a desired control parameter set point indicative of an optimal energy efficiency rating for the refrigeration unit as a function of the selected operating parameters, sensing the instantaneous value of the control parameter, comparing the sensed instantaneous value of the control parameter to the calculated control parameter set point, and adjusting the operating speed of the condenser fans associated with the air-cooled condenser of the refrigeration unit in response to that comparison.
