How to calculate condensing unit and cooling coil?
Hi all,
I am looking for the formula to calculate the proper condensing unit for 75,000 BTU and the cooling coil for 65,000 BTU? Is there a simple way for it?
Thank you.

What is the application temps, and ambient temps, single compressors or multi compressors. More information would get a few responses.

Re: How to calculate condensing unit and cooling coil?
I would use this formula
a = duty
b = size of condensing unit at working conditions
a=b
normally works for me.
Damn that is the metric version
Try this for imperial
b=aLast edited by mad fridgie; 20-01-2012 at 03:04 AM.

INFO REQUD :
SST :
DST :
REFRIGERANT TO BE USED:
REFRIGERATION LOAD :
FIRST SELECT A COMPRESSOR .........
THEN RAISE THE SUCTION SAT TEMP BY ABOUT 7 TO 10 DEG C .....
FIND OUT THE HEAT REJECTED AT THE CONDITION & THAT WILL BE THE CONDENSER HEAT REJECTION
GIVE THE CONDITIONS & WILL WORK OUT A COD UNIT FOR YOU
FOR ANY HELP FURTHER SEND ME A PM : ddk0123@gmail.com

MF, I think you made a fault. It's not b=a for metric but b= c...or was it c=b...mmm...too long i used this formula
It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Always will to accept alternative theories, especially when I am wrong!, so I will have to spend weeks re-writing all my software programs, to ensure that these complex calculations are correct and up to date.
