Consider an air$-$conditioning system where air flows over tubes carrying refrigerant $134$ a $.$ The air enters with a rate of $226\mathrm{.}2k\frac{g}{m}in$ at $\frac{1\mathrm{.}10}{b}ar,32C$ and exits at $\frac{0\mathrm{.}95}{b}ar,12C.$ The refrigerant enters the tubes at $4\mathrm{.}0$ bar with a quality of $24\%$ and flows at constant pressure exiting at $20C.$ Determine the refrigerant mass flow rate $m_R^{}$ in $k\frac{g}{m}in$ and the rate of heat transfer $Q_R^{}$ in $k\frac{J}{m}in$ from the refrigerant to the air. Ignore heat transfer at the outer surface of the air conditioner and neglect kinetic and potential energy effects.

$($a$)m_R^{}=k\frac{g}{m}in$

$($b$)Q_R^{}=k\frac{J}{m}in$
