Abstract:
1. A multivariate system for controlling a refrigeration system, comprising: a plurality of inputs which together represent a plurality of independent variables representing a thermodynamic operational state of the refrigeration system; a memory storing data describing a thermodynamic predictive mathematical model of the refrigeration system associated with the plurality of inputs, the model being adaptively defined based on prior operational states of the plurality of inputs and having at least one adaptively defined timeconstant; at least one processor, configured to receive the plurality of inputs, to access the stored model, to perform an analysis of the model with respect to the plurality of inputs to determine a probable deviance from an optimal operating point, and to determine change in the operational state of the refrigeration system to achieve a predicted most-efficient operational state; and an output port configured to present an output signal representing the determined change in the operational state.
