Thank you flyrfan.
The big picture is that Carrier intentionally gives no useful information about the variable speed fan performance. In particular, variable speed fans, are designed to work best at very low ESP, probably at 0.2". The general requirement of good efficient duct design is to...
Thank you flyrfan.
I have seen this data. This table is very next to useless for the following reasons:
(1) it does not show how much power it takes to blow the air at any given ESP
(2) for COMFORT setting it shows nothing at all
All it shows is that the blower can deliver the same pre-set CFM...
Thank you trashcanman but:
(1) carrier stopped publishing this data and refuses to give it. There could be some data from comparable commercial unit or released in the past.
(2) Duct work must be matched to the blower performance data as per engineering practice and Manual D, and than per...
The 2006 International Residential Code section N1103.2.1 and the federal Energy Code both require a minimum of R8 insulation of any outdoor ducts and ducts in vented areas. Some jurisdictions made federal Energy Code voluntary, but the IRC is the independent code requirement and most cities...
I am looking for Carrier Infinity 50XT (5Ton) blower performance data, i.e. ESP (external static pressure) vs. CFM vs. Watts in any form.
Also looking for a solid reference stating that residential/commercial ducts should be designed at certain ESP, say 0.2" or 0.5 -- but what is the number...
