In this paper

the mathematical model and experimental platform of the cross-flow heating tower are established. The effect of non-uniform liquid distribution on heat and mass transfer performance in the cross-flow heating tower is studied under different fluid flow and air volume conditions. The results show that the total heat exchange has an inverted “U” curve relation to the uniformity coefficient of liquid distribution

σ. The higher the absolute value of the uniformity coefficient of liquid distribution

|σ| is

the worse the total heat exchange performs. When the mass flow rate of the solution is 1.4 kg/s and σ=0-1

the total heat exchange capacity decreases from 13.60 kW to 12.01 kW(a decrease of 11.69%). The heat and mass transfer performance of the cross-flow heat source tower is related to the size of σ

and has nothing to do with the direction of σ.
