Re: Designing a Condenser
hello Salman,
Condenser capacity is not measured by meters but by capacity,
Q [heat you want to reject] = compressor cooling capacity + compressor current draw [+ 10% to 15%]
Thats in KW.
Now you can find the condenser size.
Re: Designing a Condenser
Is compressor current draw in Amperes?
My compressor is 320 KW refrigerant capacity and it will draw 125-130 amperes.

All parameters should be in KW.
Re: Designing a Condenser
Hi Salman,
I might be able to suggest on condenser capacity . But I need the following info:
1) Evaporation temp :
2) condensing TEMP :
3) Comp capacity : 320 kw
4) Kirloskar comp model : Please confirm Model : KC-6 ?? @750 RPM
5) Refrigerant : AMMONIA
6) You will need evaporative condenser .....

Re: Designing a Condenser
Dear Salman,
You need to calculate the total heat of rejection to know exactly what will be your condenser load.
Total heat of rejection can be calculated as total refrigeration load (In KW) + motor power (of compressors in KW if load is in KW) and a correction factor depending on your difference in Dry & Wet bulb.
Then you can use the formula of surface heat transfer i.e: heat transfer coefficient X surface area X log.mean of temperature difference.
Here the temperature difference would be discharge temperature - condensing temperature.
I believe this cold storage is in Lahore (Kasur) I think I have seen this one already :)
Anybody here give some suggestions to refine this, improve this please..
