Title (EN) SCROLL COMPRESSORS
(FR) COMPRESSEURS EN SPIRALE
Abstract:
(EN) A method of improving the efficiency of a pair of first and second scroll refrigeration compressors, at least the second of which includes an intermediate port is characterised in that the delivery of the first scroll compressor is fed into the intermediate port of the second scroll compressor at a pressure corresponding to the intermediate port in the compression process occurring in the second scroll compressor.
(FR) L'invention se rapporte à un procédé d'amélioration de l'efficacité d'une paire de premier et second compresseurs de réfrigération en spirale, au moins le second comprenant un orifice intermédiaire. Ce procédé se caractérise en ce que l'admission du premier compresseur en spirale soit raccordée à l'orifice intermédiaire du second compresseur en spirale à une pression correspondant à l'orifice intermédiaire dans le processus de compression survenant dans le second compresseur en spirale.
