Try changing the infiltration air change per hour to zero and to 2 to compare.
There may be other compoent included in the total cooling load.

Subject: [EnergyPlus_Support] A question about Latent Cooling Load in E+
| Dear Colleagues, I got a question about latent cooling load in EnergyPlus. The simulation settings are: a single zone with constant cooling setpoint (26â?? through the day), no internal heat gain, 1 air changes per hour and "Idea Load Air System" automatically used for HVAC configuration. Theoratically, due to there is no internal heat gain in this case, the follow correlation should be valid: "Total cooling load - Total sensible cooling load = Latent cooling load = Infiltration latent heat gain". But the simulation results shown that the infiltration latent heat gain is always less than the latent cooling load (Total cooling load - Total sensible cooling load), 2% for this case (8-9% less was found in other simulation case). I cannot understand why the infiltration heat gain is not equal to the calculated latent cooling load. Really headache! Look forward to discussing with you, thanks very much.
Best regards,
Xiaoshan |
