On the influence of the refrigerant inlet position and circuitry layout on plate-finned tube evaporator performance through the hybrid method

Multiple factors can impact the performance of a plate-.inned tube evaporator in terms of heat transfer rate and refrigerant pressure drops, including the circuitry layout and the position of the refrigerant distributors. In order to assist designers, various circuitry layout alternatives together with different refrigerant inlet positions were examined in this work, using the hybrid method to calculate the evaporator performance. Based on prediction functions coming from the outcomes of either numerical, analytical, or experimental analysis, the hybrid method has the advantage of combining affordable computing costs with accurate .indings. Moreover, the refrigerant inlet position can cause uneven vapor quality entering the various circuits. This characteristic, along with the variation in .low rates it implies, was also examined to investigate their in.luence on the heat exchanger's performance.
