The formula to calculate the Coefficient of Performance of Refrigerator (COPRefrigerator) is:
\[ \text{COP}_{\text{Refrigerator}} = \frac{Q_{\text{low}}}{RW} \]
The Coefficient of Performance of Refrigerator is defined as heat at a lower temperature per unit of work. Heat from Low Temperature Reservoir is the heat of the material at a lower temperature. Refrigerator work is the work done by the refrigerator in an interval of temperature change.
Let's assume the following values:
Using the formula:
\[ \text{COP}_{\text{Refrigerator}} = \frac{200}{1000} \approx 0.2 \]
The Coefficient of Performance of Refrigerator is approximately 0.2.
| Heat from Low Temperature Reservoir (Joule) | Refrigerator Work (Joule) | COP of Refrigerator |
|---|---|---|
| 150 | 1000 | 0.150000000000000 |
| 175 | 1000 | 0.175000000000000 |
| 200 | 1000 | 0.200000000000000 |
| 225 | 1000 | 0.225000000000000 |
| 250 | 1000 | 0.250000000000000 |
