Title (EN) ERICSSON CYCLE MACHINE
(FR) MACHINE A CYCLE D'ERICSSON
Abstract:
(EN) An Ericsson cycle machine is disclosed which can be used for refrigeration, liquefaction of nitrogen or as an engine. The invention includes a liquid ring compressor (23) linked to a liquid ring expander (29) by a gas loop that includes a recuperator (42). As a refrigeration unit, the liquid ring in the compressor is channeled through a heat exchanger (24) to reject waste heat and liquid is tapped from the expander liquid ring and used as a refrigerant.
(FR) L'invention se rapporte à une machine à cycle d'Ericsson qui peut être utilisée comme unité de réfrigération, comme unité de liquéfaction de l'azote ou comme moteur. Cette machine comprend un organe (23) de compression d'un anneau de liquide, qui est relié à un organe (29) d'expansion d'un anneau de liquide par une boucle de gaz qui contient un récupérateur (42). Lorsque la machine est utilisée comme unité de réfrigération, l'anneau de liquide contenu dans l'organe de compression est canalisé à travers un échangeur thermique (24), de façon à rejeter la chaleur résiduaire, et du liquide est prélevé dans l'anneau de liquide de l'organe d'expansion pour être utilisé comme réfrigérant.
