Abstract

Ce dispositif se caractérise en ce qu'il comporte un échangeur de chaleur supplémentaire dont le circuit primaire est branché entre un évaporateur et une pompe de compression et dont le circuit secondaire est intercalé entre un condenseur et une soupape de détente, cette soupape de détente étant réglée à une température ou à une pression de sortie fixe telle que la température de sortie du gaz ne soit pas inférieure à la température de solidification de la vapeur présente dans le gaz en question, et des moyens réglables de dissipation de chaleur pour le condenseur, l'agencement étant tel qu'au primaire de l'échangeur de chaleur, l'agent de refroidissement soit complètement vaporisé dans toutes les circonstances et soit légèrement surchauffe, les moyens de dissipation de chaleur étant réglables de telle manière que, quand les charges diminuent, ledit échangeur de chaleur remplisse au moins en partie le rôle du condenseur. Un des avantages du dispositif est de pouvoir fonctionner à n'importe quelle charge.This device is characterized in that it comprises an additional heat exchanger whose primary circuit is connected between an evaporator and a compression pump and whose secondary circuit is interposed between a condenser and an expansion valve, this expansion valve being set at a fixed outlet temperature or pressure such that the outlet temperature of the gas is not lower than the solidification temperature of the vapor present in the gas in question, and adjustable heat dissipation means for the condenser, the arrangement being such that at the primary of the heat exchanger the cooling medium is completely vaporized under all circumstances and is slightly overheated, the heat dissipating means being adjustable so that when the loads decrease , said heat exchanger at least partially fulfills the role of the condenser. One of the advantages of the device is that it can operate at any load.
