Hi!
I am using HVACTemplate:IdealLoadsAirSystem in EnergyPlus to estimate the heating and cooling loads to keep all zones within a building between 20 and 25 degrees Celsius.
For the time being, I have both the humidification and dehumidification control types set to None. However, looking at the output variables, I notice that DistrictHeating and DistrictCooling do not equal the Sensible Heating and Cooling being reported.
Sensible heating is reported at 973 kWh while DistrictHeating is at 977 kWh - this might seem negligible, but I am particularly concerned about sensible cooling being reported at 2745 kWh while DistrictCooling is at 3122 kWh - almost a 15% difference!
This leaves me with considerable amounts of Latent Cooling and some amounts of Latent Heating being reported - which in my understanding should not happen since humidification and dehumidification controls are both turned off.
Turning dehumidification ON does increase latent cooling loads considerably (sensible cooling loads remains exactly the same), but turning it off does not set latent cooling to zero.
So my question is, what are some possible sources (besides dehumidification) for the existence of latent cooling in the results?
Many thanks in advance.
