The evaporator (a heat exchanger) in an A/C unit has R-410A entering at -20 °C and a quality of 30% and leaves at the same temperature and a quality of 100%. The COP of the air conditioner is known to be 1.3 and the mass flow rate is given as 0.013 kg/s. Find the power input to the cycle. (Note that, here, the evaporator is the part of the A/C unit that accepts [i.e., withdraws] heat from the room maintained at a cold temperature)

Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
