US 2018/0180340 A1 · DYNAMIC POWER SENSING SYSTEM

Abstract

Systems, methods and apparatuses for monitoring the activity temperature controlled compartments of a refrigeration system by monitoring the activity of the compressor as the compressor changes between the ON or OFF state. In particular, the disclosure describes systems methods and tools for measuring the electrical loads drawn by the compressor for the purpose of predicting and determining the occurrence of unknown events from the energy profile of the compressors. One or more specialized computer systems may be connected between the compressor circuit and an energy source in order to monitor and track the amounts of energy being delivered to the compressor. The specialized computer systems measuring and tracking the electrical load supplied to the compressor may characterize the electrical load supplied as having one or more energy profiles. Each of the energy profiles may correspond to different types of events resulting in the consumption of energy by the compressor.
