The flow rate of warm air into the air conditioning is 5,000 cfm. An air conditioning system takes outdoor air at 95 degrees F dry-bulb and 70% relative humidity, and discharges it at 60 degrees F dry-bulb and 95% relative humidity. The air conditioning system operates on a vapor compression cycle using R134a between 20 and 200 psia. Refrigerant enters the compressor at 20 degrees F and leaves the compressor at 180 degrees F. Refrigerant enters the evaporator coil at a quality of x = 0.3. Determine a) The quantity of water removed from the air, in lb/min. b) The quantity of heat removed from the air, in tons. c) The mass flow rate of refrigerant, in lb/s. d) The compressor's power requirement, in hp.
