Abstract

Un système de réfrigération à compression de vapeur (A2) est composé d'un compresseur (1), d'une soupape à solénoïde à quatre voies (2), d'un condensateur (3), d'un filtre sec (4), d'une soupape d'étranglement (6), d'un évaporateur (9), d'un séparateur liquide/gaz (10), etc. Le système de réfrigération (A2) peut être utilisé dans un appareil de refroidissement/de chauffage tel qu'un climatiseur, un chauffe-eau à pompe à chaleur, etc. Un régulateur de température (25) est monté sur le condensateur (3), et peut définir une température prédéterminée. Le système de réfrigération (A2) est caractérisé en ce que l'eau chaude ayant la température de 40°C est pompée dans le réservoir d'accumulation de chaleur (22) à l'aide du régulateur de température (25) et du système de commande lorsque l'eau froide située dans le condensateur (3) est chauffée à la température définie de 40°C par la chaleur de condensation, et l'eau chaude est ensuite réchauffée à 70°C pour le lavage et le bain à l'aide de l'énergie solaire pendant les jours ensoleillés ou par des pompes à chaleur lorsque le temps est nuageux. L'appareil de refroidissement/de chauffage peut devenir une machine composite multifonctions en utilisant des soupapes à solénoïde à trois voies (30A, 30B).
