The formula to calculate the Coefficient of Performance of Refrigerator is:
\[ \text{COP}_R = \frac{Q_L}{Q_H - Q_L} \]
Where:
COP of Refrigerator given Heat in the cold and hot reservoir is the ratio of the heat removed from the system to the work required by the system.
Let's assume the following values:
Using the formula:
\[ \text{COP}_R = \frac{350}{640 - 350} \]
Evaluating:
\[ \text{COP}_R = 1.20689655172414 \]
The Coefficient of Performance of Refrigerator is 1.20689655172414.
