Evaporative Condenser Approach

03/25/2020 5:53 AM

Dear all,

I want to calculate APPROACH of an Evaporative condenser. What is the formula for it ?

It is different from the way we calculate APPROACH in a cooling tower , which is cold water temp out - wet bulb air temp.

Thank you

Hi, thanks for your reply. It does not have the formula. And i specifically need the formula for calculation of APPROACH for Evaporative Condensers.

Can you help.

Can't get any clearer than this....

..."To calculate the condenser approach temperature, first obtain the temperature of the Freon refrigerant condensing temperature found on the lower shell side of the condenser heat exchanger. Next, read the temperature of the cooling water that leaves the condenser and returns to the cooling tower. The difference between these two numbers is the condenser approach temperature."...

...which is simple subtraction.

There is no need to repeat anything in this forum, nor is there any need to SHOUT.
