Answer:
COP = 19.35
Explanation:
given,
realistic air conditioner coefficient = 3.2
to calculate maximum possible coefficient of performance at 63 ∘F inside temperature and 90 ∘F outside temperature.
for
[tex]90^0F = (90 - 32) \times \dfrac{5}{9} + 273 = 305.22 K[/tex]
[tex]63^0F = (63 - 32) \times \dfrac{5}{9} + 273 = 290.22 K[/tex]
[tex]COP = \dfrac{T_{lower}}{T_{higher}-T_{lower}}[/tex]
[tex]COP = \dfrac{290.22}{305.22-290.22}[/tex]
COP = 19.35
