Problem $12\mathrm{.}019-$ Actual refrigeration cycle

Skip to question

A refrigerator uses refrigerant$-134$a as the working fluid and operates on the vapor$-$compression refrigeration cycle. The evaporator and condenser pressures are $100\mathrm{.}0$ kPa and $1400$ kPa, respectively. The isentropic efficiency of the compressor is $88$ percent. The refrigerant enters the compressor at a rate of $0\mathrm{.}022$ kg$/$s superheated by $26\mathrm{.}37$C and leaves the condenser subcooled by $4\mathrm{.}4$C$.$
