Outre le contr\u00f4le de la temp\u00e9rature des \u00e9quipements de chauffage, les thermostats trouvent \u00e9galement de nombreuses applications dans le domaine de la r\u00e9frig\u00e9ration.<\/span><\/p>

Il s'agit d'une unit\u00e9 de commande essentielle qui recueille les valeurs de temp\u00e9rature transmises par un capteur de temp\u00e9rature, les compare \u00e0 une valeur de consigne, puis d\u00e9termine quand le compresseur doit d\u00e9marrer et s'arr\u00eater.<\/span><\/p>

Il fonctionne en association avec le capteur (en tant qu'\u00e9l\u00e9ment de r\u00e9troaction) et le compresseur (en tant qu'actionneur) pour former un syst\u00e8me en boucle ferm\u00e9e.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Le thermostat d'un r\u00e9frig\u00e9rateur fonctionne selon un principe simple <\/span>commande marche\/arr\u00eat <\/span><\/a><\/span>principe. Il compare en permanence la temp\u00e9rature de consigne \u00e0 la temp\u00e9rature r\u00e9elle \u00e0 l'int\u00e9rieur du r\u00e9frig\u00e9rateur. En fonction du r\u00e9sultat de cette comparaison, il d\u00e9cide s'il faut d\u00e9marrer le compresseur pour lancer le refroidissement ou l'arr\u00eater. Ce cycle se r\u00e9p\u00e8te en continu afin de maintenir la temp\u00e9rature souhait\u00e9e.<\/span><\/p>

Par exemple, supposons que vous ayez r\u00e9gl\u00e9 la temp\u00e9rature du compartiment r\u00e9frig\u00e9rateur sur -2 \u00b0C et que la temp\u00e9rature ambiante soit de 35 \u00b0C. Au fil du temps, la temp\u00e9rature \u00e0 l'int\u00e9rieur du compartiment r\u00e9frig\u00e9rateur augmentera progressivement en raison de la p\u00e9n\u00e9tration de la chaleur. Le capteur de temp\u00e9rature int\u00e9gr\u00e9 d\u00e9tecte cette augmentation de temp\u00e9rature et transmet la valeur mesur\u00e9e au thermostat.<\/span><\/p>

Le thermostat compare cette valeur \u00e0 la consigne de -2 \u00b0C. S'il constate que la temp\u00e9rature interne est trop \u00e9lev\u00e9e, il met imm\u00e9diatement le compresseur en marche. Apr\u00e8s un certain temps de fonctionnement du compresseur (g\u00e9n\u00e9ralement de quelques minutes \u00e0 plusieurs dizaines de minutes), la temp\u00e9rature interne redescend \u00e0 -2 \u00b0C. \u00c0 ce stade, le thermostat coupe l'alimentation du compresseur, ce qui met fin \u00e0 son fonctionnement.<\/span><\/p>

\u00c0 mesure que la temp\u00e9rature ambiante augmente, le compartiment cong\u00e9lateur<\/span>\u00a0La temp\u00e9rature remontera progressivement, et le thermostat relancera le cycle.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Les thermostats \u00e9lectroniques, \u00e9galement appel\u00e9s thermostats num\u00e9riques, sont largement utilis\u00e9s dans divers \u00e9quipements de r\u00e9frig\u00e9ration, notamment les cong\u00e9lateurs, les r\u00e9frig\u00e9rateurs et les vitrines r\u00e9frig\u00e9r\u00e9es.<\/span><\/p>

Ces thermostats sont g\u00e9n\u00e9ralement \u00e9quip\u00e9s d'un \u00e9cran num\u00e9rique et de plusieurs boutons programmables, ce qui leur permet d'effectuer des op\u00e9rations complexes.<\/span><\/p>

Outre un contr\u00f4le pr\u00e9cis de la temp\u00e9rature, ils permettent de r\u00e9guler avec pr\u00e9cision le cycle de d\u00e9givrage, de personnaliser les r\u00e9glages de temp\u00e9rature, d'assurer une surveillance \u00e0 distance via un syst\u00e8me de communication, de d\u00e9clencher des alarmes en cas de surchauffe ou de sous-temp\u00e9rature, et de g\u00e9rer le d\u00e9lai de d\u00e9marrage progressif du compresseur.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Un thermostat m\u00e9canique de r\u00e9frig\u00e9rateur est un dispositif de r\u00e9gulation de base, simple et largement utilis\u00e9 dans les r\u00e9frig\u00e9rateurs simples et les \u00e9quipements de r\u00e9frig\u00e9ration \u00e9conomiques.<\/span><\/p>

Son principe de fonctionnement est simple : lorsque la temp\u00e9rature n'a pas encore atteint ou a atteint la valeur pr\u00e9r\u00e9gl\u00e9e, le thermostat ferme ou ouvre ses contacts \u00e9lectriques en cons\u00e9quence, ce qui d\u00e9clenche ou arr\u00eate le compresseur afin de maintenir la temp\u00e9rature souhait\u00e9e.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Contrairement aux thermostats \u00e9lectroniques, qui permettent un r\u00e9glage flexible de la temp\u00e9rature, les thermostats m\u00e9caniques ne peuvent \u00eatre r\u00e9gl\u00e9s que sur un ou plusieurs niveaux de temp\u00e9rature. Par exemple, les thermostats m\u00e9caniques courants disposent de sept niveaux de temp\u00e9rature, r\u00e9glables entre 0 et 10 degr\u00e9s Celsius.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
