GATE 2016 ME (ME3) – Question 57

In the vapour compression cycle shown in the figure, the evaporating and condensing temperatures are 260 K and 310 K, respectively. The compressor takes in liquid-vapour mixture (state 1) and isentropically compresses it to a dry saturated vapour condition (state 2). The specific heat of the liquid refrigerant is 4.8 kJ/kg-K and may be treated as constant. The enthalpy of evaporation for the refrigerant at 310 K is 1054 kJ/kg. The difference between the enthalpies at state points 1 and 0 (in kJ/kg) is ____________ State 0 is saturated liquid at 260 K.
