min average max
Ambient temp 38.1 43.1 50.5
House temp 59.2 63.1 72.8
It looks like there is still a heat leak into the sunspace at night. For
instance, at 7 AM, the ambient temp was 38.1, the average house and closet
temp were about 65, and the sunspace was 54.2. If the R20 walls between the
closet and house, and the sunspace, really had an effective R-value of 20,
we would have
R20/32 ft^2 R1/32 ft^2
= Rw = Rg
65 F -------wwww-------------wwww----------- 38.1 F
|
| Tsunspace = 38.1 + (65-38.1)/(Rw+Rg) x Rg
= 39.2 F, not 54.2.
So maybe the closet is leaking warm air into the sunspace at night. Perhaps
the Tedlar film damper is stuck open, and should be replaced with something
heavier, eg Teflon.
