Janeet,
Type88 and 660 are mathematically equivalent. In addition to the internal/external controls options I believe that Type660 allows you define multiple "zones" that are adjacent to one another. Yes, feeding cold air into the ventilation inputs would be a very simplified equivalency to modeling a temperature level control building.
I would recommend using Type508 as a cooling coil model if possible and I would strongly recommend not using Type32. The others all have features that might (or might not) be useful in your particular circumstance so I'd recommend having a read through the documentation on each.
kind regards,
David
Dear experts,
Currently working on a project to simulate an absorption chiller feeding chilled water to 2 fan coil units which inturn control the temperatures of 2 zones-feeding the ventilation temp and flow rate. For comparison purposes, have set up the simple building loads using type 88 and type 660 and plan to include a temperature level control on the FCU.
1. What is the difference between the type 88 and type 660 apart from the internal conditioning equipment control. Would HVAC equipment feeding cold vent air input be equivalent to a temperature level control for the building?
2. Please advise on the differences amongst the various cooling coils - type 32, type 52, type 508, type 697, type 752. Which would be the most suitable type for the given application?
Thank you for your time in advance.
Regards,Janeet
