Question
How to calculate the CFM to TR?
What is the Formula
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
each TR = 400 CFM
thumb rule
200 Sq.ft = 1 TR ..... 150 to 200 Sq.ft = 1TR

Answer
# 6
each TR = 350 to 400 cfm as per manufacture

thumb rule

150 to 170 Sq.ft = 1 TR should not cross more than 180 sq.ft
 
Is This Answer Correct ?    23 Yes 15 No

Answer
# 7
1 TR= 400 CFM

EX. 10000CFM/400= 25 TR

Answer

We have to do Heat load calculation where we can achieve at
Grand total heat ( Sum of Grand Sen Heat + Grand Lat Heat).

TR = (GTH*1.05)/12000 TR - GTH in Btu/Hr

Calculation of TR from CFM is a thumb rule and dependa upon
inside design conditions. For Comform applications ( DBT-
Inside 2DegC & 55% RH we amy consider 400 Cfm per 1 TR).

In case of low temperature ( DBT:23+/-2 Deg C and RH <50%
this can be 250 to 300 Cfm per 1 TR.

But my recommendation is to do rough Heat load calculation
which can give the appropriate TR requirement.
