[Equest-users] eQUEST Sunspace

[Jackson, Alan]

Have you tried reverse laying the interior wall? If the interior wall was defined in the sunspace, then the material layer is reversed where the interior material is layer on the sunspace side and exterior is on the interior zone side.


O  |<-GLASS [  S  ] INT-SURFACE->||<-EXT-SURFACE  [  I  ]
U  |        [  U  ]              ||               [  N  ]
T  |        [  N  ]              ||               [  T  ]
D  |        [  S  ]              ||               [  .  ]
O  |        [  P  ]              ||               [  Z  ]
O  |        [  A  ]              ||               [  O  ]
R  |        [  C  ]              ||               [  N  ]
   |<-GLASS [  E  ] INT-SURFACE->||<-EXT-SURFACE  [  E  ]

So let's say your interior wall was brick faced. The brick surface would actually be the interior layer where normally it would be the exterior layer on a standard wall exposure. Put simpler “inside” is the side in the space in which the wall was defined.

See if that helps.

Has anyone in the group used the sunspace option in eQUEST?  I have tried it and  it blew up in LOADS   Following is the .inp description of the Sunspace:

Following is the system description of the sunspace:

   DESIGN-COOL-T    = 75
   SIZING-OPTION    = ADJUST-LOADS
   SPACE            = "EL1 North Perim Plnm (G.N6)"

Following is the error message

***ERROR***********************************************************************
In routine TEMDEV for ZONE EL1 North Perim Pl Zn (G.N6)     on  2/10 hr 11 (InitialFlg =  0)
  SUNSPACE INTERIOR-WALL calculations produced bad values:
  CSSVEC (convection) =           0. CSSVEC (conduction) =     7294864.
  This would cause a  262. degree ZONE temperature change.   Values are being ignored.
  Check wall definitions for errors and report this inp/lib/wth to DOE-2 support.

Any ideas as to where I went wrong?
