Abstract

Installation frigorifique à compresseur avec deux compartiments à températures différentes, dont les évaporateurs sont en parallèle et sont desservis par un compresseur et un condenseur communs; un premier thermostat, situé dans l'un des deux compartiments, commande le compresseur et un second thermostat, situé dans l'autre compartiment, commande un dispositif d'arrêt monté en amont de l'entrée de l'évaporateur du compartiment à température supérieure. Le premier thermostat 15, commandant le compresseur 1, est disposé dans le compartiment 5 à température supérieure ; le second thermostat 18, commandant le dispositif d'arrêt 11, est disposé dans le compartiment 8 à temperature inférieure ; le dispositif d'arrêt est mis en action lorsque la température inférieure dépasse une valeur limite supérieure. Application : installations, notamment armoires frigorifiques.
