[Bldg-sim] PTAC and PTHP EER, fan energy

[Xu, Xiaowei]

Hi,

I have a quick question about the EER requirement for the PTAC and PTHP
system. In Standard 2004, Table 6.8.1D gives out the minimum requirement
for the PTAC and PTHP system. My question is does this EER include the
fan power or not?

 

Also for the PTAC and PTHP system, following the Appendix G fan power
energy calculation, the fan power would be about 0.7~0.8W/cfm. However
the manufacture's catalog data usually gives out the value around
0.2~0.3W/cfm, which means the proposed case would get a lot of fan
energy savings. Does this make sense? Thanks a lot.
