Abstract

This article presents experimental results on the effect of refrigerant distribution in microchannel a parallel flow evaporator that is part of an air conditioner/heat pump system that operates with CO2 in transcritical cycle. The improvements of COP achieved are as high as 20%. Three different refrigerant feeding strategies are discussed.
