An air-conditioning system is shown in the figure below in which air flows over tubes carrying Refrigerant 134a. Air enters with a volumetric flow rate of (AV)₁ = 170 m³/min at 32°C, 1 bar, and exits at 22°C, 0.95 bar. Refrigerant enters the tubes at 5 bar with a quality of 20% and exits at 5 bar, 20°C. R-134a Py = 5 bar Ty= 0.20 (AV)₁ Refrigerant 134a Air P₁ = 1 bar T₁= = 32°C=305 K Air 2+P₂-0.95 bar T₂=22°C = 295 K R-134a P4= 5 bar T₁=20°C Ignoring heat transfer at the outer surface of the air conditioner, and neglecting kinetic and potential energy effects, determine at steady state: (a) the mass flow rate of the refrigerant, in kg/min. (b) the rate of heat transfer, in kJ/min, to the air from the refrigerant. An air-conditioning system is shown in the figure below in which air flows over tubes carrying Refrigerant 134a.
