HAP report cooling load difference

HAP report cooling load difference

RE: HAP report cooling load difference

The load on the AHU is going to be a comprised of the office sensible AND latent loads as well as the outside air sensible and latent loads.
It seems that this design has a large proportion of outdoor air (~84%). This is going to be a large contribution to your coil load.

Whether the inputs to this calculation are correct is another question, the OA percentage seems very high.

RE: HAP report cooling load difference

The high OA flow is driving the load. You are correct with the design condition of 107F DB. I review the Air System Design Summary output to see which parts of the envelope, internal loads, fans/pumps or ventilation which are driving the load in terms of SHG and LHG to the zone. This design looks like a MAU serving a lab or kitchen.

RE: HAP report cooling load difference

Yes its 100% OA. Thank you DrRTU and lukaiENG!
