Given left frac right fluidnh
Qg = (ṁ3h3+ṁ5h5) − (ṁ4h4+ṁ6h6) [2]
ṁ3X3 + ṁ5X5 = ṁ4X4 + ṁ6X6 [3]
ṁ9 = ṁ10 [6]
Qcon = ṁ9h9 − ṁ10h10 [7]
ṁ11 = ṁ12 [13]
Qe = ṁ11h11 − ṁ12h12 [14]
Heat Exchanger
ṁ2 = ṁ4 [18]
The COP is adopted for the cycle performance evaluation. It is defined as cooling capacity output divided by the sum of heat input and pump work, given by;
$${COP}_{Ref} = \left( \frac{Q_{l}}{Q_{g} + W_{P}} \right)$$
