Abstract

L'invention porte sur un échangeur de chaleur pour un dispositif de réfrigération, tel qu'un échangeur de chaleur d'un dispositif extérieur d'un climatiseur, qui est divisé, en correspondance avec un trajet supérieur et un trajet inférieur, en une pluralité de sections d'échange de chaleur, comprenant au moins une section d'échange de chaleur d'étage supérieur dans laquelle un fluide de refroidissement ne reste pas et une section d'échange de chaleur d'étage inférieur dans laquelle le fluide de refroidissement reste. Chacun parmi des tuyaux ramifiés correspondant aux sections d'échange de chaleur respectives comporte une soupape de détente électronique et un capteur d'échange de chaleur, et utilise ceux-ci pour régler respectivement les pressions de fluide de refroidissement correspondant aux sections d'échange de chaleur respectives. Ceci peut empêcher la diminution des performances d'échange de chaleur durant une opération en charge intermédiaire et réduire la quantité d'énergie d'entrée totale, y compris une quantité d'énergie d'entrée pour entraîner un ventilateur, ce qui économise par là même de l'énergie.
