$(25$prs$)$ A vapor compression refrigeration system using R$-22$ operates at evaporating and

condensing temperatures of $0\backslash$deg C and $36\backslash$deg C$,$ respectively. With the use of a liquid$-$to$-$suction heat

exchanger, the refrigerant exiting from the evaporator is heated from the saturated vapor $(0\backslash$deg C$)$ to

$5\backslash$deg C$,$ and, at the same time, the refrigerant exiting from the condenser is cooled from the saturated

liquid $(36\backslash$deg C$)$ to the subcooled state. A reciprocating compressor has a piston displacement of $0\mathrm{.}002$

m$^(3)$ vith a clearance volume ratio of $5\mathrm{.}0\%,$ and the crankshaft rotates at $40$re$($v$)/($s$).$ The adiabatic

efficiency and the motor efficiency of the compressor are $0\mathrm{.}85$ and $0\mathrm{.}95,$ respectively, and k$=1\mathrm{.}4$k$($g$)/($s$)$ W$^()=$m$^()($n$)/(($n$-1))$P$\_($v$\_($b$))[(($P$\_($c$))/($P$\_($b$)))^(($n$-1)/($n$))-1]$
