1. There is a steam compression refrigeration cycle using R-134a as working fluid. Pressure of the evaporator and condenser is 0.14 MPa and 0.8 MPa, respectively. If the evaporator outlet is saturated vapor and the condenser outlet is saturated liquid, find the following. (A) The work applied per kilogram of working fluid in a compressor. (B) Heat dissipation per kilogram of working fluid in the condenser. (C) Heat absorption per kilogram of working fluid in the evaporator. (D) Pe ormance coefficient when used as a heat pump p ; however, the following values are known.
