Abstract

Le circuit comporte, dans une disposition en série, un compresseur 25, un condensateur 28, un tube capillaire 31, un premier évaporateur 14, un conduit 33 muni d'un premier robinet 34 et un second évaporateur 18 raccordé à l'entrée du compresseur. Un conduit 39 muni d'un second robinet 40, monté en parallèle avec le condenseur et le capillaire, raccorde directement le compresseur au premier évaporateur et un conduit 41 muni d'un étranglement 42 est monté, en parallèle avec le conduit 33, entre les deux évaporateurs. En service normal, le premier robinet 34 est ouvert et le second robinet 40 est fermé. Lors du dégivrage, le premier robinet 34 est fermé et le second robinet 40 est ouvert et le compresseur est maintenu en fonctionnement de sorte que le premier évaporateur 14 fonctionne en condenseur et est rapidement dégivré. L'invention est applicable, notamment, aux meubles-présentoirs frigorifiques.
