2ZoneDataCenterHVAC_wEconomizer performance discrepancies between 22-2-0 and 8-6-0

Issue overview

Run "energyplus -w USA_IL_Chicago-OHare.Intl.AP.725300_TMY3.epw -r -x -d output 2ZoneDataCenterHVAC_wEconomizer.idf"

The East Data Center results in very high temperatures, much higher than the cooling setpoint 23C. Some examples:

EAST ZONE:Zone Air Temperature [C](TimeStep)
45.4322699737891
46.6604832262426
47.2421209546278
47.4094961562255
47.413785803083
47.2434725514975
47.169790378188

EAST AIR LOOP OUTLET NODE:System Node Temperature [C](TimeStep)
40.3986960976602
41.2043134854439
41.464040595099
41.334086230615
41.0832801503033
41.0573809536309

Is this expected result - when the cooling setpoint is 23 C? Running the same simulation with version 8-6-0 gets seemingly reasonable results, where the temperatures were around 23C.

The West Data Center is OK.

Checklist

Add to this list or remove from it as applicable. This is a simple templated set of guidelines.

• Defect file added (list location of defect file here)
• Ticket added to Pivotal for defect (development team task)
• Pull request created (the pull request will have additional tasks related to reviewing changes that fix this defect)

Reproduce the issue with the listed energyplus command, USA_IL_Chicago-OHare.Intl.AP.725300_TMY3.epw, and 2ZoneDataCenterHVAC_wEconomizer.idf under versions 22-2-0 and 8-6-0. Compare the East and West zone temperatures and air-loop outlet results. Done means determining whether the 22-2-0 discrepancy is expected and, if not, identifying the defect and updating the checklist items.
