Question

Refrigerant 134a enters the compressor of a refrigerator as superheated vapor at 0.20 mpa at -10°c at a rate of 1.0 kg/s and it leaves at 1.2 mpa and 70°c. The refrigerant is cooled in the condenser to 44°c and 1.15 mpa and it is throttled to 0.12 mpa. Disregarding any heat transfer and pressure drops in the c

Answer 1

Answer:

Refrigerant-134a data: T = 20°C: hf = 79.3 kJ/kg, hg = 261.6 kJ/kg; P = 1400 ... in the condenser to 44°C and 1.15 MPa, and it is throttled to 0.21 MPa.
