Claims (10)

  1. Ejektor, der omfatter: en primær indgang (40); en sekundær indgang (42); en udgang (44); en primær strømningsbane fra den primære indgang til udgangen; en sekundær strømningsbane fraden sekundære indgang til udgangen; en blanderkonvergenssektion (114; 300; 400) på nedstrømssiden af den sekundære indgang; en drivdyse (100), der omgiver den primære strømningsbane på opstrømssiden af en samling med den sekundære strømningsbane og har: en hals (1 06); og en udgang (110) og en aktuator (204), der er koblet til drivdysen for at bevirke en relativ forskydning af drivdyseudgangen og blanderkonvergenssektionen i strømningsretningen, kendetegnet ved, at: koblingen er effektiv til at tilvejebringe den relative forskydning i strømningsretningen langs et bevægelsesinterval mellem en relativt udstrakt tilstand og en relativt tilbagetrukket tilstand; over bevægelsesintervallet er udgangen (110) inde i konvergenssektionen (114; 300; 400); konvergenssektionen har en længde (Lc); drivdysen (100) rager ind i konvergenssektionen (114; 300; 400) med en overlapning (LP); og bevægelsesintervallet omfatter forhold mellem overlapningen (LP) og længden (Lc) på 0,4-0,7.
  2. 2. Ejektor ifølge krav 1, hvilken ejektor endvidere omfatter: en styreenhed (140), der er konfigureret til at styre aktuatorens (204) funktion.
  3. 3. Ejektor ifølge krav 2, hvilken ejektor endvidere omfatter: en trykføler ved ejektorudgangen (44), en trykføler ved den sekundære indgang (42), en styreenhed (140), der er konfigureret til dynamisk at måle den aktuelle trykstigning ved måling af trykket ved ejektorudgangen (44) og den sekundære indgang (42) og ved subtraktion af disse to værdier og til at bevæge drivdysepositionen for at finde den maksimale trykstigningsværdi.
  4. 4. Ejektor ifølge krav 1 eller 3, hvilken ejektor endvidere omfatter: en nål (132), der er monteret til gensidig bevægelse langs den primære strømningsbane mellem en første position og en anden position; og en nåleaktuator (134), der er koblet til nålen for at bevirke nålens bevægelse i forhold til drivdysen.
  5. 5. Ejektor ifølge krav 1, hvor: aktuatoren omfatter en stepmotor.
  6. 6. Ejektor ifølge krav 1, hvor: en general halvvinkel langs længden (Lc) er 5-30°.
  7. 7. Kølesystem, der omfatter: en kompressor (22); en varmeafvisningsvarmeveksler (30), der er koblet til kompressoren for at modtage kølemiddel, der er komprimeret af kompressoren; ejektoren ifølge krav 1; en varmeabsorberingsvarmeveksler (64) og en udskiller (48), der har: en indgang (50), der er koblet til udgangen fra ejektoren for at modtage kølemiddel fra ejektoren; en gasudgang (54) og en væskeudgang (52).
  8. 8. Fremgangsmåde til drift af systemet ifølge krav 7, hvilken fremgangsmåde omfatter: komprimering af kølemidlet i kompressoren; afvisning af varme fra det komprimerede kølemiddel i varmeafvisningsv armeveksleren; passage af en strøm af kølemidlet gennem den primære ejektorindgang; passage af en sekundær strøm af kølemidlet gennem den sekundære indgang for blanding med den primære strøm; måling af ét eller flere driftsparametre, og, som reaktion på de målte driftsparametre, at forårsage, at aktuatoren bevirker den relative forskydning i strømningsretningen.
  9. 9. Fremgangsmåde ifølge krav 8, hvor: forskydningen i strømningsretning forbedrer en virkning af ejektoren og en effektfaktor for systemet.
  10. 10. Fremgangsmåde ifølge krav 8, hvor: funktionen styres af en styreenhed (140), der er programmeret til at styre aktuatorens funktion.
