Max,
If you have access to the TESS HVAC library you will find a Type508 cooling coil model that includes the control mode that you are looking for.
kind regards,
David
Hi there, I have a question concerning a cooling coil. I want to model a cooling coil Type 123. My goal is to implement a set temperature for the outlet fluid temperature. For example: Cooling power should only be provided if the inlet air temperature is above 20°C and then the coil should have a set temperature for the outlet air temperature to be around 21°C. How can I do this? On/Off Controller doesn't work because there is always the error that the cooling capacity must be greater than 0 which obviously isnt the case if the inlet temperature is below 20°C. I have tried it with an equation and a gt-function but the result isnt satisfying. Thanks for your help!
