Question
Chapter 15, Problem 92QAP
To determine
(a)
Show that EER can be expressed as Qc (BTU) /W (W.h) and is therefore nothing more than the coefficient of performance CP expressed in mixed units.
To determine
(b)
Show that the EER is related to the coefficient of performance CP by the equation
To determine
(c)
Typical home freezer of temperature 0.00 F and an outside kitchen temperature of about 70.0 F What is the co-efficient of performance for such a freezer, and how does it compare to the coefficient of performance of the best possible freezer operating between those temperature?
To determine
(d)
What is the EER of the best possible freezer in part (c).
