RE: [EnergyPlus_Support] Cold Room

As far is modeling in EnergyPlus is concerned, a cold room would be better served by refrigeration equipment, not air conditioning equipment -- see the input objects Refrigeration:AirChiller, ZoneHVAC:RefrigerationChillerSet, etc.

Subject: [EnergyPlus_Support] Cold Room




I would like to ask a question about cold rooms. I have been modeling a cold room conditioned at 4°C during the year by air conditioners. In the baseline building, all thermal zones at the same floor are conditioned by the same air handling unit according to ASHRAE 90.1 2007, Appendix G. I think it would be wrong that all these zones are conditioned by the same air handling unit throughout the year for this special case. Because other thermal zones have different set-point temperatures (21°C) than cold room.  In the baseline building, the air handling unit should blow the air at very low temperature during the year for conditioning the cold room at 4°C. Therefore, it would be a problem for setting the set-point temperatures of other zones.

What should I do in this special case?

Best Regards
