Abstract

Il compressore rotativo è costruito in modo tale che due tubazioni del refrigeratore dell'olio siano disposte in vicinanza di due elementi di compressione posti alle estremità opposte di un elemento di azionamento elettrico. Con questa costruzione, le prestazioni di raffreddamento del compressore rotativo possono essere raddoppiate. Inoltre, poiché le due tubazioni del refrigeratore dell'olio e due scambiatori di calore sono collegati l'uno con l'altro in serie, non sorge la necessità di ingrandire il volume del compressore rotativo aumentando il diametro dello stesso. In alternativa, il compressore rotativo può includere una tubazione di refrigeratore per condurre il refrigerante in una tubazione di refrigeratore dell'olio e un ventilatore per raffreddare contemporaneamente in modo forzato un serbatoio chiuso e la tubazione di refrigeratore. In questo caso, poiché la temperatura del gas refrigerante da far scorrere nella tubazione di refrigeratore dell'olio può essere abbassata, il lubrificante può essere raffreddato con un alto rendimento. Pertanto, viene fornito un compressore rotativo del tipo chiuso che può manifestare prestazioni sufficientemente alte, alte proprietà e alta affidabilità senza alcuna necessità di ingrandire il volume del compressore rotativo.
