摘要：
Temperature stratification in the exit stream of cooled air from the plate and fin evaporator in automotive air conditioning occurs under low operating loads. Numerical simulations and analyses show that this malfunction is caused by the uneven distribution of the refrigerant liquid from the two-phase mixture in the header towards the evaporating channel. The applied numerical approach is validated for available experimental conditions. Refrigerant two-phase flows in a header of improved design are numerically investigated and a reduction of the temperature stratification is demonstrated.
