CONTROLLER AND METHOD FOR IMPROVING THE EFFICIENCY OF HEATING AND COOLING SYSTEMS
First Claim
1. A method for providing system data for evaluating a steady-state performance of a system, the method comprising:
- providing at least one sensor in an operating heating, ventilation, air conditioning or refrigeration system, the system having at least one cycle;
sampling real-time data at a predefined frequency using the at least one sensor;
computing average values using some of the real-time data for a predefined time interval;
writing to a memory storage device one or more parameters of the system cycle, one or more computed average values, one or more E/C performance parameters, and one or more refrigeration parameters according to a pre-determined bin structure as a first data set; and
providing all or a portion of the data set over a communications network for evaluating the performance and increasing the efficiency of the system.

Abstract
A computerized hardware and software system and a method for processing and storing measured data from various inputs (sensors) that reduces the data memory requirements and data transmission requirements of heating, ventilation, air conditioning, and/or refrigeration systems (HVAC&R) by creating a more compact data structure that retains data resolution, as required, based on the intended use of the measured data. The system and method are especially applicable to data processing and storage associated with the monitoring of such thermal equipment and systems but may be used in other data collection of other types of systems where system performance monitoring is desired.

13. An apparatus for evaluating the performance and efficiency of a steady-state system by providing information over a communications network, comprising:
-
at least one sensor for providing an output corresponding to at least one measurable operating parameter; a signal conditioning and converter circuit for processing the output; a microprocessor for assigning at least some of the data into at least one pre-determined bin, wherein the bin is used for minimizing the amount of memory space for storing the output in a memory device; and a communications network for transmitting the bin information for subsequent evaluation. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
