Solar Absorption Refrigeration System COP Calculation:
A solar absorption refrigeration system consists of four main components: a generator, an absorber, a condenser, and an evaporator. The COP (Coefficient of Performance) of a refrigeration system is defined as the ratio of the cooling effect produced to the amount of work input required. The maximum possible COP of a solar absorption refrigeration system can be calculated as follows:
1. Determine the generator temperature (Tg), absorber temperature (Ta), condenser temperature (Tc), and evaporator temperature (Te) in Kelvin.
Given: Tg = 360 K, Ta = 300 K, Tc = 300 K, Te = 270 K
2. Calculate the temperature difference between the generator and absorber (Tg-Ta) and between the condenser and evaporator (Tc-Te).
ΔT1 = Tg - Ta = 60 K
ΔT2 = Tc - Te = 30 K
3. Calculate the ratio of the temperature differences (ΔT1/ΔT2).
ΔT1/ΔT2 = 60/30 = 2
4. Calculate the maximum possible COP using the formula:
COPmax = ΔT1 / (ΔT1 - ΔT2)
COPmax = 60 / (60 - 30) = 60 / 30 = 2
5. Convert the COPmax into a percentage.
COPmax% = COPmax x 100
COPmax% = 2 x 100 = 200%
6. Divide the COPmax% by 100 to obtain the COPmax in decimal form.
COPmax = COPmax% / 100
COPmax = 200% / 100 = 2/1 = 1.5
Therefore, the maximum possible COP of the solar absorption refrigeration system with the given temperatures is 1.5.
