WebEvaporator is an important and widely used heat exchanger in air conditioning and refrigeration industries. Different methods have been used by investigators to increase the heat transfer rates in evaporators. One of the passive techniques to enhance WebThe biggest challenge in the evaporator distribution system is to maintain a uniform distribution of vapor and liquid phases in the evaporator. Uneven distribution will create poor refrigeration effect.
