A Heat Pump Cycle Is Executed with R-134a Under the Saturation

A heat pump cycle is executed with R-134a under the saturation dome between the pressure limits of 1.6 MPa and 0.2 MPa. If the power consumption of the heat pump is 4.2 kW, the maximum rate of heat supply to the heated space is

A) 4.20 kJ/s
B) 3.58 kJ/s
C) 20.4 kJ/s
D) 16.2 kJ/s
E) 0.86 kJ/s
