Amirreza,
Often times in situations like this you need to add internal controls to the piece of equipment that is being controlled. The cooling coil model in the TESS HVAC Library, some of the solar collectors in the TESS Solar library, and the detailed cooling tower model in the standard v18 library are all examples if you want to look at some code. You'd need to program an internal iterative scheme into the evaporative cooler that is designed to find the flow rate that results in the outlet air temperature that you are looking for.
kind regards,
David

Dear All
I have two air streams in my model, each of them passing from some components like evaporatuive cooler.One of them is cold air, and the other is humid. I want to condense the moisture content of one of them using another but in some hours the dew point of moist air is higher then the cold air temperature so the moisture could not be condensed. Tthe humidity of moist air is dependent to the it's flow rate, so if I could adjust the flow rate such as the moist air dew point could be maintained lower than the coild air temperature at each hour, we could produce significant water. Is there any way in TRNSYS to control the air flow rate such as the moist air dew point maintains lower than the cold air temperature?Thank you
