Title (EN) HEAT EXCHANGER AND REFRIGERATION DEVICE
(FR) ÉCHANGEUR DE CHALEUR ET DISPOSITIF DE RÉFRIGÉRATION
(JA) 熱交換器又は冷凍装置
Abstract:
(EN) This indoor heat exchanger (25) is provided with an upwind heat exchange unit (50) in which a first gas-side port (GH1) is formed, a downwind heat exchange unit (60) in which a second gas-side port (GH2) is formed, and a connection tube (70) which forms a connection flow path (RP). The upwind heat exchange unit (50) includes an upwind first header (56), an upwind second header (57) and heat transfer tubes (45), and the downwind heat exchange unit (60) includes a downwind first header (66), a downwind second header (67) and heat transfer tubes (45). During heating operation, in the upwind heat exchange unit (50), a super cooling region (SC1, SC2), an "upwind, outlet-side space" (the upwind sixth space (A6)) communicating with a liquid-side port (LH), and an "upwind, upstream-side space" (the upwind third space (A3)) upstream of the "upwind, outlet-side space" in the refrigerant flow are formed. The connection flow path (RP) allows communication between the "downwind, downstream-side space" (the downwind second header space (Sb2) furthest downstream in the refrigerant flow in the downwind heat exchange unit (60)) and the "upwind, upstream-side space".
(FR) La présente invention concerne le présent échangeur de chaleur intérieur (25) qui est pourvu d'une unité d'échange de chaleur au vent (50) dans laquelle un premier orifice côté gaz (GH1) est formé, d'une unité d'échange de chaleur sous le vent (60) dans laquelle un second orifice côté gaz (GH2) est formé et un tube de raccordement (70) qui forme un trajet d'écoulement de raccordement (RP). L'unité d'échange de chaleur au vent (50) comprend un premier collecteur au vent (56), un second collecteur au vent (57) et des tubes de transfert de chaleur (45) et l'unité d'échange de chaleur sous le vent (60) comprend un premier collecteur sous le vent (66), un second collecteur sous le vent (67) et des tubes de transfert de chaleur (45). Lors de la mise en œuvre du chauffage, dans l'unité d'échange de chaleur au vent (50), une région de super-refroidissement (SC1, SC2), un « espace latéral de sortie, au vent » (le sixième espace au vent (A6)) communiquant avec un orifice côté liquide (LH) et un « espace côté amont, au vent » (le troisième espace au vent (A3)) en amont de l'« espace côté sortie, au vent » dans l'écoulement de fluide réfrigérant sont formés. Le trajet d'écoulement de raccordement (RP) permet la communication entre l'« espace côté aval au vent » (le second espace de collecteur sous le vent (Sb2) le plus en aval dans l'écoulement de fluide réfrigérant dans l'unité d'échange de chaleur sous le vent (60)) et l'« espace côté amont, sous le vent ».
(JA) 室内熱交換器(25)は、第1ガス側出入口(GH1)を形成される風上熱交換部(50)と、第2ガス側出入口(GH2)を形成される風下熱交換部(60)と、接続流路(RP)を形成する接続配管(70)とを備える。風上熱交換部(50)は風上第1ヘッダ(56)と風上第2ヘッダ(57)と伝熱管(45)とを含み、風下熱交換部(60)は風下第1ヘッダ(66)と風下第2ヘッダ(67)と伝熱管(45)とを含む。暖房運転時には、風上熱交換部(50)において、過冷却域(SC1、SC2)、液側出入口(LH)に連通する「風上出口側空間」(風上第6空間(A6))、及び「風上出口側空間」の冷媒流れ上流側の「風上上流側空間」(風上第3空間(A3))が形成される。接続流路(RP)は、「風下下流側空間」(風下熱交換部(60)の冷媒流れの最も下流側の風下第2ヘッダ空間(Sb2))と「風上上流側空間」とを連通させる。
