Abstract:
(EN) Provided is an air conditioning system that suppresses degradation in reliability. This air conditioning system (100), which performs a refrigeration cycle in a refrigerant circuit (RC), is provided with: an outdoor unit (10); a plurality of indoor units (40); a liquid-side communication pipe (La) that forms a liquid-side communication circuit (RC3a), through which at least a refrigerant in a gas-liquid two-phase state flows, between the outdoor unit (10) and the indoor units (40). The liquid-side communication pipe (La) has: liquid-side branch portions (BPa) including a branch pipe group (88); and trap parts (T1). The branch pipe group (88) is a plurality of branch pipes (80) that communicate with some of the indoor units (40). The liquid-side branch portions (BPa) branch the refrigerant from the outdoor unit (10) side. The trap parts (T1) are provided to at least some of the branch pipes (80). The trap parts (T1) fill with the refrigerant in a gas state.
(FR) La présente invention concerne un système de climatisation qui supprime la dégradation de fiabilité. Ce système de climatisation (100), qui effectue un cycle de réfrigération dans un circuit de fluide frigorigène (RC), est pourvu de : une unité extérieure (10) ; une pluralité d’unités intérieures (40) ; un tuyau de communication côté liquide (La) qui forme un circuit de communication côté liquide (RC3a), à travers lequel au moins un fluide frigorigène dans un état biphasique gaz-liquide s’écoule, entre l’unité extérieure (10) et les unités intérieures (40). Le tuyau de communication côté liquide (La) comporte : des parties de dérivation côté liquide (BPa) comprenant un groupe de tuyaux de dérivation (88) ; et des parties de piège (T1). Le groupe de tuyaux de dérivation (88) est une pluralité de tuyaux de dérivation (80) qui communiquent avec certaines des unités intérieures (40). Les parties de dérivation côté liquide (BPa) dévient le fluide frigorigène depuis le côté d’unité extérieure (10). Les parties de piège (T1) sont disposées au niveau d’au moins certains des tuyaux de dérivation (80). Les parties de piège (T1) remplissent avec le fluide frigorigène dans un état gazeux.
(JA) 信頼性低下を抑制する空調システムを提供する。空調システム(100)は、冷媒回路(RC)において冷凍サイクルを行う空調システム(100)であって、室外ユニット(10)と、複数の室内ユニット(40)と、室外ユニット(10)及び室内ユニット(40)間で少なくとも気液二相状態の冷媒が流れる液側連絡回路(RC3a)を形成する液側連絡配管(La)と、を備える。液側連絡配管(La)は、支管群(88)を含む液側分岐部分(BPa)と、トラップ部(T1)と、を有する。支管群(88)は、いずれかの室内ユニット(40)に連通する複数の支管(80)である。液側分岐部分(BPa)は、室外ユニット(10)側から流れる冷媒を分岐させる。トラップ部(T1)は、少なくともいずれかの支管(80)に設けられる。トラップ部(T1)は、ガス状態の冷媒を充満させる。
