Abstract
A system for monitoring an outdoor heat exchange coil of a heating or cooling system includes a neural network for computing the status of the coil. The neural network is trained during a development mode to learn certain characteristics of the heating or cooling system that will allow it to accurately compute the status of the coil. The thus trained neural network timely computes the status of the outdoor heat exchange coil during a run time mode of operation. Information as to the status of the coil is made available for assessment during the run time mode of operation.

A process for monitoring the condition of an outdoor heat exchange coil in a heating or cooling system comprising the steps of:
- reading values of information concerning certain operating conditions of the heating or cooling system wherein at least some of the values are produced by sources of information located within the heating or cooling system;
- processing the read values of information concerning the operating conditions of the heating or cooling system through a neural network so as to produce a computed indication of the condition of the outdoor heat exchange coil that is based on having processed the read values through the neural network;
- comparing the computed indication of the condition of the outdoor heat exchange coil with at least one predetermined value for the condition of the outdoor heat exchange coil of the heating or cooling system;
- and
- transmitting a status message as to the condition of the outdoor heat exchange coil in response to said step of comparing the computed indication of the condition of the outdoor heat exchange coil with at least one predetermined value for the condition of the outdoor heat exchange coil.
A process for learning the characteristics of a heating or cooling system so as to predict the condition of an outdoor heat exchange coil in the heating or cooling system, said process comprising the steps of:
- storing a plurality of sets of data in a storage device for certain operating conditions of the heating or cooling system when the system is subjected to various load and ambient conditions for various known conditions of the outdoor heat exchange coil;
- and
- repetitively processing a number of the stored sets of data through a neural network residing in a processor associated with the storage device so as to teach the neural network to accurately compute indications for at least two known conditions of the outdoor heat exchange coil for the particular sets of data whereby the neural network may be used thereafter to process data for operating conditions of the heating or cooling system wherein the condition of the outdoor heat exchange coil is unknown so as to produce a computed indication of the condition of the heat exchange coil.
