I am modelling the IdealLoadsAirSystem in energyplus with humidistat set to 50%. What does the output report Zone Ideal Loads Supply Air Latent Cooling Rate [W] actually mean? When the indoor RH is less than 50% (say 47%), I would have expected this value to be zero. The only time when this value is zero is when the sensible rate is zero and the indoor RH is less than setpoint. Does this output also include whatever latent cooling happens due to the supply air? If yes, how is it calculated - I did not notice a constant SHR. Thanks, -Rohini
