Abstract

SOUPAPE DONT L'ORGANE OBTURATEUR PREND UNE POSITION D'EQUILIBRE EN FONCTION DE LA PRESSION DE VAPEUR D'UN FLUIDE, QUI AGIT SUR UNE PREMIERE SURFACE DE PRESSION MOBILE DELIMITANT UN RESERVOIR DE PRESSION, ET D'UNE FORCE AGISSANT EN SENS CONTRAIRE, FOURNIE PAR UN RESSORT ET EVENTUELLEMENT AUSSI DE LA PRESSION REGNANT DANS L'EVAPORATEUR ET AGISSANT SUR UNE SECONDE SURFACE DE PRESSION. AU RESERVOIR DE PRESSION 17 EST ASSOCIE, POUR DETERMINER LA PRESSION DE VAPEUR, UN DISPOSITIF CHAUFFANT 31, QUI EST ALIMENTE EN ENERGIE ELECTRIQUE PAR UN ENSEMBLE DE COMMANDE 35; ON PREVOIT, POUR RAMENER LA TEMPERATURE RESPONSABLE DE LA PRESSION DE VAPEUR,UN CAPTEUR DE TEMPERATURE 33. LE FLUIDE 30 EST CHOISI DE TELLE MANIERE QUE SA TEMPERATURE, POUR UNE PRESSION DE VAPEUR PRODUISANT UN ETAT D'EQUILIBRE, EST SUPERIEURE A LA TEMPERATURE DU FLUIDE REFRIGERANT A L'INTERIEUR DE LA SOUPAPE ETOU A LA TEMPERATURE AMBIANTE. APPLICATION: INSTALLATIONS FRIGORIFIQUES.
