Hi, I would like to input [gH2O/h] in Energyplus simulation to take into account production of humidity such as shower, cooking, tumble dryer on humidity balance of a thermal zone. What is the best way? Example: For a shower I would like to input 300g/h within half an hour. Thank you.

Haave you tried the SteamEquipment object in E+? You can specify your gains in Watts and then set a 100% latent fraction, but you´ll need to convert your gH2O/h into Watts. I´m not sure if there is a more direct method.

The appendix 6.A1 of CIBSE Guide A has latent heat gain values for cooking appliances, reproduced from ASHRAE Handbook: Fundamentals (2013a).

Thank you for this suggestion Rafael, I don't have the 2013a Ashrae or the Cibse guide to see how they define latent heat gain for diverse appliance or use. Could you share them ? Don't know if this forum allow private message.

An answer in this post gives more information about how to set a $g_{water}/hr$ input like this in EnergyPlus.

Hi @AdB if it helps, I´m putting below the table I mentioned above:

Thank you Alfredo, Do you have other table detailing the heat gain rate for home use like shower, tumble dryer, ... ? Regards, Ab

@AdB, did you ever find another table with heat gain rates from other sources (shower)?
