The coefficient of performance is determined from
$$
\mathrm{COP}_{\mathrm{R}}=\frac{q_L}{w_{\text {in }}}
$$ where $$
\begin{aligned}
& q_L=\left(1-x_6\right)\left(h_1-h_8\right) \text { with } x_6=\frac{h_6-h_f}{h_{f g}} \\
& w_{\text {in }}=w_{\text {compI,in }}+w_{\text {compII,in }}=\left(1-x_6\right)\left(h_2-h_1\right)+(1)\left(h_4-h_9\right)
\end{aligned}
$$
