GAS TRAP DISTRIBUTOR FOR AN EVAPORATOR

A shell -and- tube evaporator of a refrigerant system includes a refrigerant inlet distributor that traps a pocket of gaseous refrigerant to displace liquid refrigerant underneath the evaporator's tube bundle, thereby reducing the total charge of refrigerant in the evaporator. In some embodimen...

Beschreibung
Zusammenfassung:	A shell -and- tube evaporator of a refrigerant system includes a refrigerant inlet distributor that traps a pocket of gaseous refrigerant to displace liquid refrigerant underneath the evaporator's tube bundle, thereby reducing the total charge of refrigerant in the evaporator. In some embodiments, the distributor comprises four sections interconnected by a central refrigerant feed line, which properly apportions the refrigerant to the four sections. L'invention concerne un évaporateur multitubulaire à calandre d'un système frigorigène comprenant un distributeur d'agent frigorigène qui piège une poche d'agent frigorigène gazeux pour déplacer l'agent frigorigène liquide sous le faisceau tubulaire de l'évaporateur, réduisant ainsi la charge totale d'agent frigorigène dans l'évaporateur. Dans certains modes de réalisation, le distributeur comprend quatre sections interconnectées par une conduite d'alimentation frigorigène centrale, qui répartit l'agent frigorigène de manière appropriée dans les quatre sections.
