Abstract

Cette invention se rapporte à un système de transfert de chaleur utilisable comme climatiseur, comme pompe de chaleur ou similaire et comprenant un compresseur, un condenseur, un dispositif d'expansion principal et un évaporateur raccordé en circuit fermé et dans lequel un réfrigérant est mis en circulation, ainsi qu'une dispositif de dérivation, le sous-refroidissement étant effectué dans ce dispositif de dérivation plutôt que dans la partie aval du condenseur, comme c'est le cas traditionnellement. Le dispositif de sous-refroidissement est constitué par une structure intégrée unitaire comportant un tube interne raccordable par un trajet d'écoulement de réfrigérant principal à la sortie d'un condenseur, un tube externe concentrique comportant des parties terminales fermées hermétiquement à l'extérieur du tube interne, formant ainsi une chambre entourant ledit tube interne, un orifice d'entrée raccordant le tube interne à une extrémité amont du tube externe pour permettre à une partie du réfrigérant s'écoulant dans le tube interne d'être dévié dans la chambre, à une température et à une pression réduites, un orifice de sortie situé à l'extrémité aval du tube externe ; et un conduit de retour en communication avec l'orifice de sortie et pouvant être raccordé au trajet de réfrigérant principal, pour que le réfrigérant dévié puisse s'écouler à travers la chambre assurant ainsi le sous-refroidissement du réfrigérant s'écoulant dans le tube interne et son retour ensuite dans le trajet d'écoulement du réfrigérant principal. L'orifice de sortie peut également être dimensionné pour créer une chute de pression dans le réfrigérant, lorsque celui-ci sort de la chambre, créant ainsi un différentiel de pression entre le réfrigérant dans le dispositif de dérivation et le trajet de réfrigérant principal à l'endroit de sa réintroduction.
