HAP- EXPERTS I NEED AN INQUIRY

[etchyHA]

HI
i am using a 100% FA A.H.U. with a cap. of 2000 L/S with heat recovery this AHU IS DX PACKAGE UNIT HAP output data was that the total coil load = the sensible load and it cannot be right ! there is for sure a latent load cause when i changed the type of the AHU to tempering it calculates the latent load on the coil .can i took the loads "total and sensible" only from the hap as the type " chilled water coil tempering “regardless of the actually used type DX COIL i mean??

at air system properties iam using air terminal units –split dx fan coil units the ventilation option is either
1-common ventilation system
2- direct ventilation system

the Fresh air must be supplied in 23C so after the cooling and dehumidification FA needs reheat how can i control all this on hap?

If I have the 100 % FA then I ll chose the common ventilation system and from it I ll chose vent system component what I need to be sure is if the cooling coil set point and vent reclaim tabs are the description of the 100% FA equipment I am using to serve these zones ?

Thanks in advance

What percentage of recovery are you using on the heat recovery, and did you calculate with 'total recovery'? I've noticed that HAP's treatment of heat recovery is often pretty spotty.

Is reheat at the RTU or at the terminal units? You can select reheat type at the terminal level.
