You recently purchased and installed a 6000 BTU window AC unit in your apartment. At full capacity, it consumes 600 W of electricity. How much heat is being dumped out of your window? Btu/hr What is the COP of your AC unit? (c) If your apartment is 850 ft^2, with 8 ft ceilings, and it is 90 degree|F when you turn on the AC, what will be the temperature after 10 minutes? (Assume the apartment is sealed, and ignore the and convective effects from the furnishings. Make other reasonable assumptions as needed.) degree F

Solution

Given Data,

A)

Qin=6000BTU(1758.43Watt), Win=600Watt

from heat balace equation

Qout=Qin-Win

Qout=1758.43-600

Qout=1158.43Watt

B)

COP=Qout/Win

COP=1158.43/600

COP=1.93
