Evaporator, Refrigerant Distribution, Expansion Valve


Many factors, such as loading, flow circuiting, phase separation, and distributor effectiveness determine how uniformly refrigerant is distributed within a multicircuited heat exchanger. This work describes the development of a test procedure for evaluation of refrigerant flow distribution in a multicircuited round tube evaporator as well as a comparison between a typical valve/distributor combination and a novel expansion device that integrates the distributor into the valve body. The results of this study show that refrigerant flow distribution can be made more uniform through implementation of this device.
