Re: [EnergyPlus_Support] Sensible Heat ratio in EPlus





Javed,
Latent + Sensible + Lost = 1.0 ALWAYS
For electric equipment, it is possible to have latent (moisture) load; examples are a coffee pot and an electric humidifier.
If your electric equipment generates moisture and has sensible heat ratio of 65%, then I think the latent fraction should be .35.

Hi,

I am trying to simulate a internal equipment in a zone with a known sensible heat ratio that would be transferred to the zone air heat gain. I referred I/O reference file an found following are the three heat ratios types based on source type. In my case, Fraction latent and Fraction radiation is "0" as given in the specification sheet.  My question is what would be the correct value to simulate Sensible heat ratio of 65% in the following heat ratio objects?
