Abstract
(EN)
An air conditioner comprises: an outdoor heat exchanger in which N heat exchange units are sequentially spaced in the up and down direction, a first heat exchange unit is located at the uppermost position, an Nth heat exchange unit is located at the lowermost position, and at least one heat exchange unit is located between the first heat exchange unit and the Nth heat exchange unit; N expansion valves which are respectively connected to the N heat exchange units; N hot gas pipes respectively connected to the N heat exchange units, and N hot gas valves respectively mounted on the N hot gas pipes; and a controller which controls the N expansion valves and the N hot gas valves to perform divisional defrost of the N heat exchange units, wherein the controller firstly defrosts the Nth heat exchange unit then defrosts the first heat exchange unit, and then sequentially defrosts the heat exchange units, located blow the first heat exchange unit, from a second heat exchange unit to the Nth heat exchange unit after defrosting the first heat exchange unit.

L'invention concerne un climatiseur comprenant : un échangeur de chaleur extérieur dans lequel N unités d'échange de chaleur sont espacées successivement dans les directions vers le haut et vers le bas, une première unité d'échange de chaleur étant située au niveau de la position la plus haute, une Nième unité d'échange de chaleur étant située au niveau de la position la plus basse, et au moins une unité d'échange de chaleur étant située entre la première unité d'échange de chaleur et la Nième unité d'échange de chaleur ; N détendeurs reliés respectivement aux N unités d'échange de chaleur ; N tuyaux de gaz chaud reliés respectivement aux N unités d'échange de chaleur, et N soupapes de gaz chaud montées respectivement sur les N tuyaux de gaz chaud ; et un dispositif de commande destiné à commander les N détendeurs et les N soupapes de gaz chaud afin d'effectuer un dégivrage séparé des N unités d'échange de chaleur. Le dispositif de commande dégivre premièrement la Nième unité d'échange de chaleur puis dégivre la première unité d'échange de chaleur, et dégivre ensuite successivement les unités d'échange de chaleur situées en dessous de la première unité d'échange de chaleur, de la seconde unité d'échange de chaleur à la Nième unité d'échange de chaleur, après dégivrage de la première unité d'échange de chaleur.
