Title (EN) MULTI-TYPE AIR CONDITIONING SYSTEM AND INDOOR UNIT
(FR) SYSTÈME DE CLIMATISATION DE TYPE MULTIPLE ET UNITÉ INTÉRIEURE
(JA) マルチタイプ空調システムおよび室内ユニット
Abstract:
(EN) The multi-type air conditioning system according to the present invention includes: an outdoor unit having an outside air heat exchanger; a plurality of indoor units each having an expansion valve into which a refrigerant flows after passing through the outdoor heat exchanger, and an indoor heat exchanger which exchanges heat between the refrigerant decompressed by the expansion valve and air; and a refrigerant pipe which connects the plurality of indoor units in parallel to the outdoor unit and through which the refrigerant flows. The refrigerant pipe located inside each of the indoor units has a plurality of capillaries at the location upstream of the expansion valve and along the flow direction of the refrigerant, and the capillaries are connected in parallel to the refrigerant pipe.
(FR) Le système de climatisation de type multiple selon la présente invention comprend : une unité extérieure ayant un échangeur de chaleur d'air extérieur; une pluralité d'unités intérieures ayant chacune une vanne de détente dans laquelle un fluide frigorigène s'écoule après le passage à travers l'échangeur de chaleur extérieur, et un échangeur de chaleur intérieur qui échange de la chaleur entre le fluide frigorigène décomprimé par la vanne de détente et l'air; et un tuyau de fluide frigorigène qui relie la pluralité d'unités intérieures en parallèle à l'unité extérieure et à travers lequel s'écoule le fluide frigorigène. Le tuyau de fluide frigorigène situé à l'intérieur de chacune des unités intérieures comporte une pluralité de capillaires au niveau de l'emplacement en amont de la vanne de détente et le long de la direction d'écoulement du fluide frigorigène, et les capillaires sont reliés en parallèle au tuyau de fluide frigorigène.
(JA) マルチタイプ空調システムは、室外熱交換器を有する室外ユニットと、室外熱交換器を通過した冷媒が流入する膨張弁および膨張弁で減圧された冷媒と空気との間で熱交換を行なう室内熱交換器を有する複数の室内ユニットと、室外ユニットに対し複数の室内ユニットを並列に接続するとともに冷媒が流れる冷媒配管と、を備えている。室内ユニット内に位置する冷媒配管は、膨張弁よりも冷媒の流れ方向に沿う上流側の箇所に複数本のキャピラリを有し、当該キャピラリが冷媒配管に対し並列に接続されている。
