As Shown In The Figure Refrigerant 22 Enters The Compressor Of An Air Conditioning Unit Operating At Steady State At 40 1 (45.47 KiB) Viewed 36 times

As shown in the figure, Refrigerant 22 enters the compressor of an air conditioning unit operating at steady state at 40°F, 80 lb-/in² and is compressed to 160°F, 200 lb-/in². The refrigerant exiting the compressor enters a condenser where energy transfer to air as a separate stream occurs, and the refrigerant exits as a liquid at 200 lb/in², 90°F. Air enters the condenser at 85°F, 14.7 lbf/in² with a volumetric flow rate of 750 ft³/min and exits at 110°F. Neglect stray heat transfer and kinetic and potential energy effects, and assume ideal gas behavior for the air. 5 I, = 110°F Compressor 1+ R22 at www www T₂=160°F P₂= 200 lbfin ¹ I₁ = 40°F P1-80 lbf/in.² Condenser 3 Air at T₁ P4-14.71bfin.² (AV), 73-90°F P3= 200 lbf/in. ² T T₂ = 60°F T₁ = 90°F T₁ = 40°F Determine the mass flow rate of refrigerant, in lb/min, and the compressor power, in horsepower.
