How to calculate the CFM to TR?
What is the Formula
Answer Posted / sreenivasa rao avupati
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.

If any HVDC line is going with positive & negative(the negative usually have return path of current with earthing electrode). Now the question is if this HVDC earthed electrode which is using as return path and earthed any nearby 400kv or 220kv AC substation equipments. which will be the impact of this on AC substation & its equipment, how severe may be this and what should be the minimum distance require between HVDC earthed electrode and AC substation equipments? It's really an high engineering level question...Dare to answer and increase your knowledge.
