Efficiency and Performance Flashcards
1
Q
How is the efficiency of a heat engine calculated?
A
η= NetWorkOutput / Heat Input
2
Q
How is the coefficient of performance (COP) of a refrigerator calculated?
A
COP = Q_c / W
Where
Q_c : Heat extracted
W : Work input
3
Q
What is the COP of a heat pump?
A
COP = Q_H / W
Where
Q_H : Heat delivered
