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
