Re: [EnergyPlus_Support] Latent loads with purchasedair

["Michael J. Witte" <mjwitte@xxxxxxxx>]

Purchased Air is always supplied to the zone at the user specified temperature 
and humidity condition.  All moisture balances in the zone are included in the 
simulation, including the impact of infiltration and internal latent gains.  
But Purchased Air does not actively control the zone humidity to a specific 
level.

Purchased Air Total Cooling Energy (or Rate) reports the latent and sensible 
energy required to bring the return air (plus outside air if specified) to the 
specified supply air temperature and humidity ratio.

Purchased Air Sensible Cooling Energy and Purchased Air Heating Energy report 
sensible energy only.

For definitions of Purchased Air report variables, please see the Input Output 
Reference, p. 716 (pdf p. 755).  For the equations used in Purchased Air, 
please see the Engineering Reference, p. 631 (pdf p. 667).
