Hi, i would like to know the avarege temperature difference the air entering the condenser and the temperature of the air leaving out the condenser.

Thanks alot

Probably around 10 c but would depend on duty and ambient temperature condenser coil cleanliness etc

I would agree with Philfridge around 5 to 10

Normally we design on 30 F temperature difference but what we usually get uin practical is 20-25 F IN/OUT difference

Hi sullie,

sorry but i do not know whether your condenser means air cooled OR water cooled OR hybrid type.

anyway, i learn it has direct relation to the web bulb temperature in ambient of installation.

narrow temp difference = bigger coil and vice versa.

it is economy of scale we should look into.

design is very subjective. but for air cooled, i use dT of 15K normally. BUT, do not neglect wet buld temp; it is important.

hope that helps.

Hendry, on wesak day holiday.
