latent load
(OP)
Hello
Let us say we are designing an HVAC project.
the design occupation load as per local code was for example 50 person
we have calculated load and selected equipments based on this data and the project has been constructed.
But in the actual situation the tenant of this building has only 20 employees, so what the situation would be.?
I mean the selected equipment would be oversized for the latent portion of the load, I know it is ok if the equipment was oversized for latent load but how much the percentage would be ok 5%, 10% or more.
does that result to reduce the relative humidity severly?
Can we solve this problem by using fresh air through economizer or HRV which replace the space air periodically?
thanks

RE: latent load
Even if all the other variables are correct, the surface temperatures of a room can dominate the comfort equation, still leaving the occupant uncomfortable. During winter, cold walls, floors or windows seem to suck the heat right out of a room – as well as the body. In Summer, unshaded windows or poorly-insulated walls can turn any room into a virtual oven despite lots of air-conditioning or airflow.

If the population decreases, the space cooling demand decreases, and the supply air temperature is reset up, resulting in less dehumidification.
This is typical of most system where design loads are rarely achieved.
