I am going to use series heat pipes for cooling coils in a model that I´m doing. Energyplus has an object called CoilSystem:CoolingWater:HeatExchangerAssisted to do this. I would like to know what is the average sensible heat transfer effectiveness in energyplus. I know that typical sensible heat transfer effectiveness for this kind of application is 32%. But I did not find a specific value in the engineering reference manual. I will appreciate your help. Thank you.
