In a heat exchanger, it is observed that ΔT1 = ΔT2, where ΔT1 is the temperature difference between the two single phase fluid streams at one end and ΔT2 is the temperature difference at the other end. This heat exchanger is
1
a condenser
2
an evaporator
3
a counter flow heat exchanger
4
a parallel flow heat exchanger
