Refrigerant-134a enters the coils of the evaporator of a refrigeration system as a saturated liquid-vapor mixture at a pressure of 160 kpa. the refrigerant absorbs 180 kj/kg of heat from the cooled space, which is maintained at -5°c, and leaves as a saturated vapor at the same pressure. determine
(a) the entropy change of the refrigerant,
(b) the entropy change of the cooled space, and
(c) the total entropy change for this process.
