The manufacturer of an air conditioner claims a seasonalenergy efficiency ratio (SEER) of 16 (Btu/h)/W for oneof its units. This unit operates on the normal vapor compressionrefrigeration cycle and uses refrigerant-22 as the workingfluid. This SEER is for the operating conditions when the evaporator saturation temperature is 25C and the condensersaturation temperature is 45C. Selected data for refrigerant-22are provided in the table below. (a) Sketch the hardware and the T-s diagram for this air conditioner.(b) Determine the heat absorbed by the refrigerant in the evaporatorper unit mass of refrigerant-22, in kJ/kg.(c) Determine the work input to the compressor and the heatrejected in the condenser per unit mass of refrigerant-22,in kJ/kg. snipp
