Title
(EN) EXPANSION CONTROL FOR A CLOSED FLUID CIRCULATION SYSTEM
(FR) CONTROLE DE DILATATION DANS UN SYSTEME DE CIRCULATION DE FLUIDE FERME
Abstract
(EN)
A method for expansion control in a closed fluid circulation system with varying temperature, in which system air is withdrawn from the circulating fluid through the formation of an air head wherein air to be withdrawn is collected and from which air can be blown off, controlled by a valve, to the environment or a receiving space, whilst, further, measures are taken for taking up, when the temperature varies, an attendant expansion and shrinking of the fluid within the closed system, and measures for enabling adding fluid to the system, which fluid is withdrawn from an external stock of fluid under pressure, and the air head volume is measured and when a predetermined value is exceeded, a fluid valve is opened through which fluid is introduced into the air head until the volume of the air head is substantially equal to the predetermined value and the fluid valve is closed.
(FR)
On décrit un procédé de contrôle de dilatation dans un système de circulation de fluide fermé, avec variations de température. Dans ledit système, de l'air est extrait du fluide en circulation grâce à la formation d'une charge supérieure d'air dans laquelle l'air à extraire est recueilli et peut être évacué, sous la commande d'une soupape, dans l'air ambiant ou dans un espace de réception. Ce faisant, des mesures sont prises, en outre, pour réguler, lorsque la température varie, l'expansion ou le retrait du fluide circulant dans le système fermé, ainsi que pour ajouter du fluide au système, ce fluide étant extrait d'une source extérieure de fluide sous pression. Le volume de la charge supérieure d'air est mesuré de telle façon que lorsqu'une valeur définie à l'avance est dépassée, une soupape s'ouvre par laquelle le fluide pénètre dans la charge d'air jusqu'à ce que le volume de cette dernière soit sensiblement égal à la valeur définie à l'avance, à la suite de quoi la soupape se ferme.
