Incorrect Question 1 0/20 pts Consider the R134a refrigeration cycle shown in the figure below in which a heat exchanger (HX) is added in an effort to increase the COP ref. The evaporator pressure is Pe=700 kPa and the condenser pressure is 2500 kPa. Assume the refrigerant leaves the evaporator as saturated vapor and the condenser as saturated liquid. The heat exchanger decreases the liquid temperature by 60 C (i.e., the refrigerant enters the throttling valve as a subcooled liquid). Also, assume an isentropic compressor. Calculate the ratio between the COP of this cycle and one without a heat exchanger (i.e., COP with a Hx/COPwithout_a_Hx). a out 3 2 Condenser Compress or E 11 HX Expansi on valve 4 5 Evaporator 2 6 in 1.365
