An air-conditioning system shown below has air flowing over tubes carrying Refrigerant 134a. Given the parameters below, ignoring heat transfer at the outer surface of the air conditioner, and neglecting kinetic and potential energy effects, determine at steady state the following: Air P1 =1 bar 1. T=32°C = 305 K (AV) = 50 m/min Refrigerant 134a R-134a P3 = 5 bar X3 = 0.20 R-134a P4 =5 bar T= 20°C Part a.) the mass flow rate of the refrigerant, in kg/min. Part b.) the rate of heat transfer, in kJ/min, between the air and refrigerant. Air 2+P2 = 0.95 bar T= 22°C= 295 K
