Calculate the temperature in an unheated space (Tunc) adjacent to a conditioned room with three (3) common surface areas of 175-ft2, 190-ft2, and 210-ft² with an overall heat transfer coefficient of 0.21, 0.27, and 0.32 Btu/h-Ft2 °F, respectively. The surface areas of the unheated space exposed to the outdoors are 175-ft² and 210-ft² with corresponding overall heat transfer coefficients of 0.21 and 0.40 Btu/h- Ft2 °F. The sixth (6th) surface is on the ground and can be neglected for this example as can be the effect of any outdoor air entering the space. Inside & outside design reference temperatures are 70°F & -10°F, respectively. Tunc = 37°F Tunc = 36°F Tunc = 30°F Tunc = 35°F

Question
Transcribed Image Text:Calculate the temperature in an unheated space (Tunc) adjacent to a conditioned
room with three (3) common surface areas of 175-ft2, 190-ft2, and 210-ft² with an
overall heat transfer coefficient of 0.21, 0.27, and 0.32 Btu/h-Ft2 °F, respectively.
The surface areas of the unheated space exposed to the outdoors are 175-ft² and
210-ft² with corresponding overall heat transfer coefficients of 0.21 and 0.40 Btu/h-
Ft².°F. The sixth (6th) surface is on the ground and can be neglected for this
example as can be the effect of any outdoor air entering the space. Inside & outside
design reference temperatures are 70°F & -10°F, respectively.
Tunc = 37°F
Tunc = 36°F
Tunc = 30°F
Tunc = 35°F
