Claim of US Patent No. 10,660,241

8. A system for controlling a supply air temperature adjustment for a cooling unit to optimize operation of the cooling unit with respect to room air temperature and humidity requirements, the system comprising:a controller configured to implement:
a machine learning module configured to select which portion or portions of acquired data pertaining to operation of the cooling unit are utilized;
a neural network model which uses information supplied by the machine learning module and learns an operational behavior of the cooling unit, and wherein the machine learning module performs supervised learning and regression for the neural network model;
the neural network model using information supplied by the machine learning module for generating an output;
the neural network model having a Unit Power neural network module which receives inputs from at least one other neural network models including:
a remote air temperature (RET) neural network model representing a rack inlet temperature of the cooling unit, the RET neural network model providing an output to the unit power neural network module; or
a return air temperature (RAT) neural network model for representing a temperature of air being returned to the cooling unit; or
a supply air temperature (SAT) neural network model for representing a temperature of air being generated and output by the cooling unit; and
an optimization module which receives the output from the neural network model and which implements a global optimization routine, using unit power consumption of the cooling unit as an objective function, to produce a supply air temperature set point for use by the cooling unit which optimizes an operating parameter of the cooling unit.
