Modular refrigeration unit health monitoring
First Claim
1. A modular refrigeration unit (MRU) health monitor, comprising:
- a log data input configured to receive log data from an MRU, the log data comprising a plurality of datapoints, each of the plurality of datapoints comprising a position of a control valve of the MRU and a corresponding time; and
MRU health monitoring logic configured to;
determine a plurality of MRU parameters from log data received on the log data input;
determine a plurality of MRU health flags based on the MRU parameters;
add the plurality of MRU health flags to determine an MRU health score;
determine whether the MRU health score is higher than a replacement threshold; and
indicate replacement of the MRU in the event the MRU health score is higher than the replacement threshold;
wherein the plurality of MRU health flags comprises an overtemperature recovery (OTR) rate flag, a control valve position increase flag, control valve position average flag, an expected operating threshold flag, and an OTR flag, and wherein each of the MRU health flags is set to one of zero and one based on the log data.
