Abstract

La présente invention concerne un système de conditionnement d'air à fonctionnement commandé par un fluide supercritique. La présente invention concerne en particulier l'utilisation d'un état supercritique par variation de la pression et de la température dans le système de circuit de conditionnement d'air. Dans un mode de réalisation préféré, cette modulation de l'enthalpie spécifique est réalisée par variation de la pression avant l'étranglement. Le fluide frigorifique est refroidi autant que possible au moyen du milieu de refroidissement disponible, et la pression est régulée pour donner l'enthalpie requise. La présente invention est conçue de manière efficace afin de fournir un mécanisme d'échange de chaleur permettant de résoudre des problèmes associés aux fluides frigorifiques actuellement disponibles par la fourniture de conditions écologiques, économiques, compactes et efficaces pour les exigences de moyenne à grande échelle, par exemple, bâtiments, entrepôts frigorifiques, espaces commerciaux, etc.
