[Bldg-sim] Modeling different Energy Recovery Scenarios

[Adam Niederloh]

All,

 

Happy New Year!

 

I know that I recently asked the question shown below; however I did not
receive any replies so I thought I would try again seeing as how it's a
brand new year.  The question as previously asked:  

 

 

I am curious to know what programs/methodologies people have used to
effectively model the following types of energy recovery systems:

 

1.)     Dual Wheel Heat Recovery with a Cooling Coil between the wheels.
This system is similar to the SEMCO Pinnacle system. As the outdoor air
travels through the air handler it passes first through a total energy
wheel, then through a cooling coil and then through a passive
dehumidification wheel.  The exhaust air, as it leaves the building,
travels through the passive dehumidification wheel and then the total
energy wheel.

 

2.)    Twice through Heat Recovery with a Cooling Coil in between the
first and second pass.  This system is similar to a DesertAire system.
The outside air passes through the heat recovery device, through a
cooling coil, and then through the other side of the same heat recovery
device thus pre-cooling the outdoor air and reheating the supply air.

 

Please see the attached PDF for very simple schematic sketches of each
option.

 

Thanks,

 

Adam
