CA 2596364
A parallel flow (minichannel or microchannel) evaporator includes channels which are crimped at or adjacent to their entrance location which provides for a refrigerant expansion and pressure drop control resulting in the elimination of refrigerant maldistribution in the evaporator and prevention of potential compressor flooding. Progressive crimping to counter-balance factors effecting refrigerant distribution is also disclosed.
L'invention concerne un évaporateur (à mini-canaux ou micro-canaux) à écoulement parallèle, comprenant des canaux qui sont gaufrés sur leur entrée ou adjacents, ce qui permet de fournir une expansion réfrigérante et une régulation de la perte de pression, provoquant l'élimination d'une mauvaise distribution de produit réfrigérant dans l'évaporateur et la prévention d'un engorgement potentiel du compresseur. L'invention concerne également le gaufrage progressif permettant de contrebalancer des facteurs réalisant une distribution de produit réfrigérant.
