Temperature is up because you are adding heat. Those dehumidifiers make
heat. Condensing water releases heat (A/C gets cold because it is
evaporating something the part outside gets hot because it is condensing
it.)
Note: I would agree with the vapor barrier and with looking for the
source of the moisture.
Why did you close up the vents?
