Abstract

PROCEDE DE REGULATION DE LA TEMPERATURE D'UN CORPS A UNE VALEUR DE CONSIGNE TC, CE CORPS ETANT CHAUFFE - OU REFROIDI - A PARTIR D'UN FLUIDE DE REGULATION CHAUFFANT - OU REFRIGERANT -, PAR L'INTERMEDIAIRE D'UN ECHANGEUR DE CHALEUR. LE FLUIDE DE REGULATION EST FOURNI PAR UNE SOURCE 2, 3, 4, 7, 8, 10, 11 QUI EST MUNIE DE MOYENS DE REGLAGE 11 PERMETTANT DE REGLER LA TEMPERATURE DUDIT FLUIDE; A. ON MESURE LA TEMPERATURE T DU FLUIDE DE REGULATION EN UN ENDROIT SITUE EN AMONT DE L'ECHANGEUR 5 AINSI QUE LA TEMPERATURE TA. REGNANT DANS LE MILIEU AMBIANT ENTOURANT LEDIT CORPS 1, B.ON CALCULE LA GRANDEUR T DONNEE PAR LA RELATION : T (TC - TAK) TA,OU K EST UNE CONSTANTE DETERMINEE PAR UN ETALONNAGE DE LA RELATION T F (TH), (TH) ETANT LA TEMPERATURE DU CORPS ET F (TH)(TH - TAK) TA, C.ON COMPARE T ET T ENTRE EUX, ET D.ON COMMANDE LES MOYENS DE REGLAGE 11 DE FACON QUE LA QUANTITE T - T SOIT MAINTENUE A UNE VALEUR SENSIBLEMENT NULLE. L'INVENTION S'APPLIQUE NOTAMMENT A LA REGULATION D'ENCEINTES FERMEES VENTILEES.
