[TRNSYS-users] Estimating sensible and latent loads

[Ali Shahrouzian]

Dear all TRNSYS user,

Hi,

I have two questions about estimating the size of HVAC system of a building.

My 1st question:
As you know, there is a good explanation in 09-Tutorial document regarding estimating the size of HVAC equipment of a building by using the printegrator component (setting its parameter #4 to 15 min and determining the peak 15-minute heating and cooling load for building). However, it is evident that the maximum 15-minute heating and cooling load for the building is highly dependent on the initial temperature of the building, which is set on TRNBuild. When starting a simulation, what should the initial temperature be?

My 2nd question:
How can I estimate the size of humidifier or dehumidifier in the HVAC equipment?

I'd be glad if someone could help me out.

Best regards,
Ali
