[esp-r] Unable to get Dehumidification Energy

[hiroi at mocha.ocn.ne.jp]

Hello esp-r community,

 

I am unable to get dehumidification energy values when cooling a room with
simple cooler represented by a plant network:

Zone -> Duct_in -> Cooling Coil -> Fan -> Duct_out

 

I built 3 identical (geometry, surface attribution) zones, all with a simple
cooler as described above.

The only difference is the cooling coil inlet water temperature being 5, 10,
15 degC.

Control was set to keep the zone dBT at 27 degc for all zone by controlling
the air movement volume through the cooling coil.

This was done to understand the dehumidification capability of a typical
cooler and the resulting zone RH.

The simulation result confirmed that the lower temperature cooling coil
setup reduces the zone RH, compared to higher temperature cooling coil
setup.

Unfortunately, the dehumidification energy as outputted from the "energy
delivered" summary (enquire about -> energy delivered in the Result
analyser) shows "0" for all zones.

This also the case for the output of the time plot graph.

 

ESP-r is V13.3.11 but this is also the case with V13.2.6.

 

Is there anyone who can help me out?

 

Best Regards,

Hiroi Nishimatsu
