Existing warehouse mapping was done with multiple HVAC units running simultaneously over a period of time, which included seasonal extremes. An energy-saving project is being launched to rotate HVAC unit duty cycles in lead-lag arrangements, which will create dynamic conditions, depending on load and external environmental conditions (e.g., extreme outside conditions will cause additional units to cycle on, while milder conditions will cause them to cycle off). Proposed options for this mapping currently include temporarily adding monitoring points to the BMS and allowing it to run for a minimum of 1 year, with additional monitoring probes serving as real-time validation of conditions for warehouse contents. Addition of monitoring points to the BMS may be cost-prohibitive. I am interested in hearing any other options you might consider. The warehouse cannot be taken out of service for long enough to perform these studies with loggers that have no real-time capabilities.
Can you go to non-real time monitoring? Can you have probes in the various locations that you pull, and collect data from and then put back in place.
There are probes which can collect data wirelessly, but they might have battery issues.
OMEGA Temp101A probes (tried and true) are pretty inexpensive, have a long battery, but you must connect to a laptop to get data off of (but it takes like 2 minutes). So you could possibly put it on a schedule and collect data weekly for a year.
