The formula to calculate the Coefficient of Performance (coeff_v_abs) is:
\[ coeff\_v\_abs = \frac{T_{evp} \cdot (T_{gen} - T_{cond})}{T_{gen} \cdot (T_{cond} - T_{evp})} \]
Coefficient of Performance of absorption system is defined as Cooling Duty (kW) / Generator Heating Duty (kW).
Let's assume the following values:
Using the formula:
\[ coeff\_v\_abs = \frac{202 \cdot (250 - 300)}{250 \cdot (300 - 202)} \approx -0.412244897959184 \]
The Coefficient of Performance is approximately -0.412244897959184.
