Abstract
Flow mal-distribution in fin-and tube evaporators for residential air-conditioning is investigated by
numerical simulation. In particularly, the interlaced and the face split evaporator are compared in flow maldistribution
conditions. The considered sources of mal-distribution are: Liquid/vapor distribution and airflow
distribution. Furthermore, compensation of flow mal-distribution by control of individual channel superheat
is studied for each type of evaporator. It is shown that the interlaced evaporator is better at flow maldistribution
than the face split evaporator. However, if individual channel superheats are controlled, the face
split evaporator achieves the best performance, i.e. an increase of 7% in UA-value and 1.6% to 2.4% in COP
compared to the interlaced evaporator without compensation.
