Calculation of Air Temperature in Plumbing Chase Enclosed by Heated Space & Outdoor Temperature
Calculation of Air Temperature in Plumbing Chase Enclosed by Heated Space & Outdoor Temperature
(OP)
ENGINEERS:
I am attempting to determine the air temperature of the interior of a plumbing/pipe chase that is enclosed by an ABS shower stall (55 F inside the stall in the living space), and by a wood stud-frame wall with only friction-fit 3-1/2 inch fiberglass batt insulation (no interior or exterior finish board on either side of the studs) between the studs to enclose the exterior side of the batt (exposed to the interior of a porch roof space vented to the outside)from -5 F outdoor temperatures. The batt is the only component that separates the cold-air space above the porch roof from the interior of the pipe chase.
If the inside surface temperatures of wall construction of an interior wall and an exterior wall can be determined from resistances of the materials and interior/exterior temperature differentials, can the temperature of the air in the space in a pipe chase (between the walls) in an attic be determined with reasonable accuracy?
If so, how? Do the calculated surface temperatures of the wall areas exposed to the pipe chase assist in determining the air temperature in the space? If so, how?
Could it reasonably be theorized that the air temperature in the chase is the average of the temperatures of the surfaces of exterior & interior walls that face the interior of the enclosed plumbing chase?
Thank you,
