Abstract
Selon la présente invention, un espace dont la température doit être contrôlée est maintenu à une température de point de réglage désirée en réglant la température du réfrigérant à la sortie d'un évaporateur 15 d'un dispositif de refrigération. Quand la temperature dans l'espace tend à varier par rapport au point de réglage choisi en raison d'un changement de charge thermique, le dispositif de commande modifie automatiquement le débit de réfrigérant par l'intermédiaire d'une électrovanne 13 pour établir les conditions souhaitées. Plus particulièrement, en réponse à un accroissement de température dans le compartiment, le débit du réfrigérant croît et en réponse à une chute en dessous du point de réglage, le débit décroît L'électro-vanne 14 sert d'une part à commander le débit, d'autre part de dispositif de détente. Quand la charge thermique sur l'évaporateur est constante, le débit de réfrigerant est commandé pour maintenir la température de sortie de l'évaporateur fixe au point de commande souhaité Application aux climatiseurs pour véhicules automobiles, camions, autobus, etc
