The maximum possible Coefficient of Performance (COP) for an absorption refrigeration system is determined by the temperatures of the evaporator ($T_L$), generator ($T_G$), and condenser/heat sink ($T_S$). For a reversible cycle, the COP can be calculated using the formula: $COP_{ideal} = \frac{T_L (T_G - T_S)} {T_G (T_S - T_L)}$
In an absorption refrigeration system, the refrigeration temperature is -15 °C. The generator is operated by solar heat, where the temperature reaches to 110 °C. The temperature of the heat sink is 55 °C. What is the maximum possible COP of the system ? - (5) Question not attempted
