[Equest-users] DOE2.2 Systems EVAP-COOL and PTGSD

[Chris Jones]

I am trying to determine the difference between EVAP-COOL, DOE2.2 
System Type #26 and PTGSD, DOE2.2 System #25.  Both are listed in the 
list of system types in BDLKey.OUT.  But only EVAP-COOL is mentioned 
in the Topics Reference manual.  The Library Reference Manual only states:
SUPL Evap/ Desiccant Cooling for <system name>
This report is printed for each system that has a desiccant or 
evaporative cooling unit to supplement the mechanical cooling.
These are systems for which the user has specified DESICCANT = 
LIQ-VEOT-AIR-1, LIQ-VENT-AIR-2, or SOL-
VENT-AIR-1; or EVAP-CL-TYPE = INDIRECT or INDIRECT-DIRECT. This 
report will not be printed for stand-
alone desiccant or evaporative cooling systems (SYSTEM:TYPE = PTGSD 
or EVAP-COOL). In this case the usual
SYSTEMS reports are used.

It would seem that these are two different systems by the above 
reference but given that there is no reference to PTGSD in Topics, I 
am left wondering if the only difference is that PTGSD is, by 
default, packaged desiccant cooling?
