Description
本発明は、冷媒ユニットに関するものである。 The present invention relates to a refrigerant unit.
車両用等の熱管理システムは、冷媒回路の吸放熱を利用して、車室内空調等の温調対象に対する熱管理を行うものである。熱管理システムの心臓部である冷媒回路は、車両等の装置内での集中管理を可能にするため、或いは、スペース効率良く装置内に配備できるようにするために、構成要素をコンパクトにユニット化することが求められている。 Thermal management systems for vehicles, etc., use the heat absorption and release of the refrigerant circuit to perform thermal management of temperature-controlled objects such as the air conditioning of the vehicle interior. The refrigerant circuit, which is the heart of the thermal management system, is required to have its components compactly unitized in order to enable centralized management within the device, such as the vehicle, or to enable space-efficient deployment within the device.
ユニット化された冷媒回路（冷媒ユニット）は、冷媒回路の構成要素である、圧縮機、蒸発器又は凝縮器として機能する熱交換器、減圧装置（膨張弁）、気液分離器（アキュムレータ）などを、ベースとなる支持部材に対して集約配置して、ユニットのアッセンブル化を図っている（下記特許文献１参照）。 A unitized refrigerant circuit (refrigerant unit) assembles the components of the refrigerant circuit, such as a compressor, a heat exchanger that functions as an evaporator or condenser, a pressure reducing device (expansion valve), and a gas-liquid separator (accumulator), by concentrating them on a base support member (see Patent Document 1 below).
このような冷媒ユニットでは、各構成要素を、冷媒ユニット全体の重量バランスや冷媒流路となる冷媒配管やその接続部等による各構成要素間の接続関係などを考慮しながら配置して、可能な限り小型化することが求められる。
また、冷媒回路における冷媒流路は、流路長を短くすることで冷媒流路における冷媒の熱損失や圧力損失を抑えることができるため、冷媒流路を可能な限り短くして効率よく取り回すことも求められる。
In such a refrigerant unit, it is necessary to make the individual components as small as possible by arranging them while taking into consideration the weight balance of the entire refrigerant unit and the connection relationships between the individual components via the refrigerant piping that serves as the refrigerant flow path and their connections, etc.
Furthermore, since heat loss and pressure loss of the refrigerant in the refrigerant flow path in the refrigerant circuit can be reduced by shortening the flow path length, it is also required to make the refrigerant flow path as short as possible for efficient routing.
本発明は、このような問題に対処することを課題としている。すなわち、冷媒回路の構成要素をユニット化した冷媒ユニットにおいて、各構成要素を接続する冷媒流路を可能な限り短くして冷媒ユニットの小型化を図ること、などが本発明の課題である。 The present invention aims to address these problems. In other words, the objective of the present invention is to reduce the size of a refrigerant unit by shortening the refrigerant flow paths connecting the components of the refrigerant circuit as much as possible in a refrigerant unit that unitizes the components of the refrigerant circuit.
このような課題を解決するために、本発明の一態様に係る冷媒ユニットは、以下の構成を具備するものである。
冷媒回路と、前記冷媒回路の構成要素を集約的に支持する支持部材とを備えた冷媒ユニットであって、前記冷媒回路は、圧縮機と、第１熱交換器と、前記第１熱交換器とは機能の異なる複数の第２熱交換器とを少なくとも有し、前記支持部材は、前記圧縮機を固定する第１固定面と、前記第１熱交換器及び複数の前記第２熱交換器を固定する第２固定面とを有し、前記圧縮機と前記第１熱交換器とを繋ぐ第１冷媒配管、及び、前記圧縮機と複数の前記第２熱交換器とを繋ぐ第２冷媒配管を、前記第１固定面及び前記第２固定面を貫通するように設けた、冷媒ユニット。
In order to solve such problems, a refrigerant unit according to one aspect of the present invention has the following configuration.
A refrigerant unit comprising a refrigerant circuit and a support member that collectively supports components of the refrigerant circuit, the refrigerant circuit having at least a compressor, a first heat exchanger, and a plurality of second heat exchangers having a function different from that of the first heat exchanger, the support member having a first fixing surface to which the compressor is fixed and a second fixing surface to which the first heat exchanger and the plurality of second heat exchangers are fixed, a first refrigerant piping that connects the compressor and the first heat exchanger, and a second refrigerant piping that connects the compressor and the plurality of second heat exchangers are provided so as to penetrate the first fixing surface and the second fixing surface.
このような特徴を有する冷媒ユニットは、冷媒回路の構成要素をユニット化した冷媒ユニットにおいて、各構成要素を接続する冷媒流路を可能な限り短くして冷媒ユニットの小型化を図ることができる。 A refrigerant unit with these characteristics can reduce the size of the refrigerant unit by shortening the refrigerant flow paths connecting each component as much as possible in a refrigerant unit in which the components of the refrigerant circuit are unitized.
以下、本発明を実施するための形態について、図面を参照しつつ詳細に説明する。以下の説明において、同一の符号は同一の機能の部位を示しており、各図における重複説明は適宜省略する。 Below, the embodiment of the present invention will be described in detail with reference to the drawings. In the following description, the same reference numerals indicate parts with the same functions, and duplicate descriptions in each drawing will be omitted as appropriate.
図１及び図２は、本実施形態に係る冷媒ユニット１０の斜視図である。本実施形態に係る冷媒ユニット１０は、冷媒回路を構成する各構成要素を支持部材１２に固定してユニット化したものであり、例えば、走行用バッテリを備えた車両に搭載され、車室内の空調や車載機器の温度調整などを行う空調装置や熱管理システムに用いられる。 Figures 1 and 2 are perspective views of the refrigerant unit 10 according to this embodiment. The refrigerant unit 10 according to this embodiment is a unit formed by fixing each component of the refrigerant circuit to a support member 12, and is installed in a vehicle equipped with a driving battery, for example, and is used in an air conditioning device or thermal management system that conditions the air in the vehicle cabin and adjusts the temperature of on-board equipment.
各図に示すように、冷媒ユニット１０は、圧縮機２０、アキュムレータ２２、第１熱交換器３０、第２熱交換器４１，４２、流路方向切替手段としての四方弁６０、膨張弁７１，７２を含む減圧装置７０、及び、電磁弁８１，８２を含む流入出制御装置８０、冷媒流路としての冷媒配管５１，５２Ａ，５２Ｂ，９１～９４によって接続した冷媒回路と、これらを集約的に支持する支持部材１２とを備えている。 As shown in each figure, the refrigerant unit 10 includes a compressor 20, an accumulator 22, a first heat exchanger 30, a second heat exchanger 41, 42, a four-way valve 60 as a flow direction switching means, a pressure reducing device 70 including expansion valves 71, 72, an inflow/outflow control device 80 including solenoid valves 81, 82, a refrigerant circuit connected by refrigerant pipes 51, 52A, 52B, 91-94 as a refrigerant flow path, and a support member 12 that collectively supports these.
支持部材１２は、略矩形状の板状部材である底板部１５と、底板部１５と一体的に形成され、底板部１５の中央部において底板部１５に対して垂直に設けられる略矩形状の板状部材である固定壁１６とを有している。底板部１５及び固定壁１６は、冷媒ユニット１０に備えられた各構成要素と冷媒配管が干渉しない十分な高さ及び幅を有している。 The support member 12 has a bottom plate portion 15, which is a substantially rectangular plate-like member, and a fixed wall 16, which is a substantially rectangular plate-like member formed integrally with the bottom plate portion 15 and disposed perpendicular to the bottom plate portion 15 at the center of the bottom plate portion 15. The bottom plate portion 15 and the fixed wall 16 have sufficient height and width so that the refrigerant piping does not interfere with the components provided in the refrigerant unit 10.
底板部１５は、固定壁１６が設けられている面（図示Ｚ方向上側の面）が冷媒回路の構成要素が配備されて固定される固定面（表面）であり、固定壁１６と反対側の面（図示Ｚ方向下側の面）が冷媒ユニット１０を車体等に取り付けるための取付面（裏面）となっている。底板部１５の取付面の４隅を、ゴムブッシュ１１を介して締結具１３によってそれぞれ締結することで、冷媒ユニット１０を車体等の取付対象に取り付けることができる。 The surface of the bottom plate 15 on which the fixed wall 16 is provided (the surface on the upper side in the Z direction in the figure) is the fixed surface (front side) on which the components of the refrigerant circuit are arranged and fixed, and the surface opposite the fixed wall 16 (the surface on the lower side in the Z direction in the figure) is the mounting surface (back side) for mounting the refrigerant unit 10 to a vehicle body or the like. The refrigerant unit 10 can be mounted to a mounting target such as a vehicle body by fastening the four corners of the mounting surface of the bottom plate 15 with fasteners 13 via rubber bushings 11.
底板部１５における固定面は、固定壁１６によって隔てられる２つの領域１５Ａ，１５Ｂを有している。底板部１５において、領域１５Ａ側には、圧縮機２０、アキュムレータ２２、四方弁６０、及び、流入出制御装置８０が配備され、領域１５Ｂ側には、第１熱交換器３０、第２熱交換器４１，４２、及び、減圧装置７０が配備されている。 The fixed surface of the bottom plate portion 15 has two areas 15A and 15B separated by a fixed wall 16. In the bottom plate portion 15, the compressor 20, the accumulator 22, the four-way valve 60, and the inflow/outflow control device 80 are arranged on the side of the area 15A, and the first heat exchanger 30, the second heat exchangers 41 and 42, and the pressure reducing device 70 are arranged on the side of the area 15B.
固定壁１６は、その両面に冷媒回路の各構成要素が固定される。固定壁１６において、底板部１５の領域１５Ａ側の面が圧縮機２０、アキュムレータ２２、四方弁６０、及び、流入出制御装置８０を固定する第１固定面１６Ａであり、領域１５Ｂ側の面が第１熱交換器３０、第２熱交換器４１，４２、及び、減圧装置７０を固定する第２固定面１６Ｂである。 The components of the refrigerant circuit are fixed to both sides of the fixed wall 16. In the fixed wall 16, the surface on the area 15A side of the bottom plate portion 15 is the first fixed surface 16A to which the compressor 20, the accumulator 22, the four-way valve 60, and the inflow/outflow control device 80 are fixed, and the surface on the area 15B side is the second fixed surface 16B to which the first heat exchanger 30, the second heat exchangers 41 and 42, and the pressure reducing device 70 are fixed.
図３は、第１固定面１６Ａ側から見た冷媒ユニット１０の平面図であり、圧縮機２０、アキュムレータ２２、四方弁６０、及び、流入出制御装置８０の位置関係を示している。 Figure 3 is a plan view of the refrigerant unit 10 as viewed from the first fixed surface 16A side, showing the relative positions of the compressor 20, accumulator 22, four-way valve 60, and inflow/outflow control device 80.
図３に示すように、固定壁１６において、第１固定面１６Ａには、圧縮機２０、アキュムレータ２２、四方弁６０、及び、流入出制御装置８０が固定される。具体的には、圧縮機２０は、底板部１５の領域１５Ａから離間した状態で直接または図示しないブラケットを介して第１固定面１６Ａに固定されている。また、アキュムレータ２２は、図示Ｘ方向において圧縮機２０と隣接し、底板部１５の領域１５Ａから離間した状態で直接または図示しないブラケットを介して第１固定面１６Ａに固定されている。 As shown in FIG. 3, the compressor 20, the accumulator 22, the four-way valve 60, and the inflow/outflow control device 80 are fixed to the first fixed surface 16A of the fixed wall 16. Specifically, the compressor 20 is fixed to the first fixed surface 16A directly or via a bracket (not shown) while spaced apart from the region 15A of the bottom plate portion 15. The accumulator 22 is adjacent to the compressor 20 in the illustrated X direction, and is fixed to the first fixed surface 16A directly or via a bracket (not shown) while spaced apart from the region 15A of the bottom plate portion 15.
四方弁６０は、アキュムレータ２２の図示Ｚ方向上部に固定されると共に、図示しないブラケットを介して第１固定面１６Ａに固定されている。ここで、固定壁１６の四方弁６０と第１熱交換器３０とが固定される位置に、固定壁１６を貫通する貫通孔１６３が設けられている。 The four-way valve 60 is fixed to the upper part of the accumulator 22 in the Z direction as shown, and is also fixed to the first fixed surface 16A via a bracket (not shown). Here, a through hole 163 that penetrates the fixed wall 16 is provided at the position where the four-way valve 60 and the first heat exchanger 30 are fixed to the fixed wall 16.
この貫通孔１６３に、第１熱交換器３０の冷媒流入出口３０Ａ（図５及び図６参照）に設けられた冷媒配管９２の一端との接続部３５が挿入されている。冷媒配管９２の他端は四方弁６０に接続されている。したがって、四方弁６０は、冷媒配管９２と貫通孔１６３に挿入される接続部３５とを介して第２固定面１６Ｂ側に固定される第１熱交換器３０に取り付けられ、固定壁１６を挟んで第１固定面１６Ａ側に固定される。 A connection part 35 for one end of a refrigerant pipe 92 provided at the refrigerant inlet/outlet 30A (see Figures 5 and 6) of the first heat exchanger 30 is inserted into this through hole 163. The other end of the refrigerant pipe 92 is connected to the four-way valve 60. Therefore, the four-way valve 60 is attached to the first heat exchanger 30 fixed to the second fixing surface 16B side via the refrigerant pipe 92 and the connection part 35 inserted into the through hole 163, and is fixed to the first fixing surface 16A side with the fixing wall 16 in between.
流入出制御装置８０は、圧縮機２０の上部に固定されている。流入出制御装置８０には、第２熱交換器４１，４２に対応する２つの電磁弁８１，８２と、電磁弁８１，８２に対して冷媒が合流して流入する合流部又は分岐して流出する分岐部となる接続部８３が設けられている。電磁弁８１，８２は、圧縮機２０の上部において、図示Ｘ方向に並んで配置される。電磁弁８１，８２が配置される位置は、第２固定面１６Ｂに固定される第２熱交換器４１，４２の位置に対応している。 The inflow/outflow control device 80 is fixed to the top of the compressor 20. The inflow/outflow control device 80 is provided with two solenoid valves 81, 82 corresponding to the second heat exchangers 41, 42, and a connection part 83 which serves as a junction where the refrigerant merges and flows into the solenoid valves 81, 82 or a branch part where the refrigerant branches and flows out. The solenoid valves 81, 82 are arranged side by side in the X direction in the figure on the top of the compressor 20. The positions at which the solenoid valves 81, 82 are arranged correspond to the positions of the second heat exchangers 41, 42 fixed to the second fixing surface 16B.
ここで、固定壁１６には、貫通孔１６１，１６２が設けられ、貫通孔１６１，１６２には、第２固定面１６Ｂ側に固定される第２熱交換器４１，４２と第１固定面１６Ａ側に固定される電磁弁８１，８２とを接続する接続部（不図示）が挿入される。電磁弁８１，８２は、貫通孔１６１，１６２に挿入される接続部を介して第２熱交換器４１，４２に取り付けられ、固定壁１６を挟んで第２熱交換器４１，４２が設けられる第２固定面１６Ｂと反対側の面である第１固定面１６Ａ側に固定される。 Here, the fixed wall 16 is provided with through holes 161, 162, and connectors (not shown) are inserted into the through holes 161, 162 to connect the second heat exchangers 41, 42 fixed to the second fixed surface 16B side and the solenoid valves 81, 82 fixed to the first fixed surface 16A side. The solenoid valves 81, 82 are attached to the second heat exchangers 41, 42 via connectors inserted into the through holes 161, 162, and are fixed to the first fixed surface 16A side, which is the surface opposite the second fixed surface 16B on which the second heat exchangers 41, 42 are provided, across the fixed wall 16.
図４は、第２固定面１６Ｂ側からみた冷媒ユニット１０の平面図であり、第１熱交換器３０、第２熱交換器４１，４２、及び、減圧装置７０の位置関係を示している。
図４に示すように、固定壁１６において、第２固定面１６Ｂには、第１熱交換器３０、減圧装置７０、及び、第２熱交換器４１，４２が同一方向（図示Ｘ方向）に並んで配置されている。すなわち、第２固定面１６Ｂにおいて、減圧装置７０を挟んで一方側に第１熱交換器３０、他方側に第２熱交換器４１，４２が固定されている。また、第１熱交換器３０、第２熱交換器４１，４２はいずれも平行に配置されている。
FIG. 4 is a plan view of the refrigerant unit 10 as viewed from the second fixing surface 16B side, and shows the positional relationship between the first heat exchanger 30, the second heat exchangers 41, 42, and the pressure reducing device 70.
4, in the fixed wall 16, the first heat exchanger 30, the pressure reducing device 70, and the second heat exchangers 41, 42 are arranged side by side in the same direction (the X direction in the figure) on the second fixed surface 16B. That is, on the second fixed surface 16B, the first heat exchanger 30 is fixed on one side of the pressure reducing device 70, and the second heat exchangers 41, 42 are fixed on the other side. In addition, the first heat exchanger 30 and the second heat exchangers 41, 42 are all arranged in parallel.
減圧装置７０は、第２熱交換器４１，４２に対応する２つの膨張弁７１，７２と、膨張弁７１，７２の間に、膨張弁７１，７２に対して冷媒が合流して流入する合流部又は分岐して流出する分岐部となる接続部７３とを有している。膨張弁７１，７２は、第１熱交換器３０と第２熱交換器４１，４２との間において、第１熱交換器３０と第２熱交換器４１，４２とが配列される方向（図示Ｘ方向）と直交する方向（図示Ｚ方向）に並んで配置されている。 The pressure reducing device 70 has two expansion valves 71, 72 corresponding to the second heat exchangers 41, 42, and a connection 73 between the expansion valves 71, 72, which serves as a confluence where the refrigerant merges and flows into the expansion valves 71, 72 or a branch where the refrigerant branches and flows out. The expansion valves 71, 72 are arranged side by side between the first heat exchanger 30 and the second heat exchanger 41, 42 in a direction (Z direction) perpendicular to the direction in which the first heat exchanger 30 and the second heat exchangers 41, 42 are arranged (X direction).
（第１熱交換器３０及び第２熱交換器４１，４２について）
第１熱交換器３０及び第２熱交換器４１，４２は、冷媒と熱媒体（例えば、水）との熱交換を行う冷媒－熱媒体熱交換器であり、冷媒の熱を、熱媒体回路（図示せず）を介して温調対象に供給することで車室内の空調や車載機器の温調などを行う。
(Regarding the first heat exchanger 30 and the second heat exchangers 41, 42)
The first heat exchanger 30 and the second heat exchangers 41, 42 are refrigerant-heat medium heat exchangers that exchange heat between a refrigerant and a heat medium (e.g., water), and perform air conditioning in the vehicle cabin and temperature control of on-board equipment by supplying the heat of the refrigerant to a temperature control target via a heat medium circuit (not shown).
第１熱交換器３０には、冷媒の流通方向に応じて冷媒流入部又は冷媒流出部となる一対の冷媒流入出口３０Ａ，３０Ｂが設けられている（図５及び図６参照）。同様に、第２熱交換器４１には、冷媒の流通方向に応じて冷媒の流入口又は流出口となる一対の冷媒流入出口４１Ａ，４１Ｂが設けられ、第２熱交換器４２には、冷媒の流通方向に応じて冷媒の流入口又は流出口となる一対の冷媒流入出口４２Ａ，４２Ｂが設けられている。各冷媒流入出口には、後述する冷媒配管が接続される（図５及び図６参照）。 The first heat exchanger 30 is provided with a pair of refrigerant inlet/outlet ports 30A, 30B that serve as the refrigerant inlet or outlet port depending on the flow direction of the refrigerant (see Figures 5 and 6). Similarly, the second heat exchanger 41 is provided with a pair of refrigerant inlet/outlet ports 41A, 41B that serve as the refrigerant inlet or outlet port depending on the flow direction of the refrigerant, and the second heat exchanger 42 is provided with a pair of refrigerant inlet/outlet ports 42A, 42B that serve as the refrigerant inlet or outlet port depending on the flow direction of the refrigerant. Refrigerant piping, described later, is connected to each refrigerant inlet/outlet port (see Figures 5 and 6).
本実施形態に係る冷媒ユニット１０では、四方弁６０により冷媒の流通方向を切り替えることが可能であり、第１熱交換器３０及び第２熱交換器４１，４２は、冷媒の流通方向に応じて蒸発器又は凝縮器として機能する。この際、第１熱交換器３０と第２熱交換器４１，４２とは、互いに異なる機能を有するようになっている。 In the refrigerant unit 10 according to this embodiment, the four-way valve 60 can switch the flow direction of the refrigerant, and the first heat exchanger 30 and the second heat exchangers 41, 42 function as an evaporator or a condenser depending on the flow direction of the refrigerant. In this case, the first heat exchanger 30 and the second heat exchangers 41, 42 have different functions.
すなわち、冷媒ユニット１０では、四方弁６０を制御して冷媒の流通方向を切り替えることで、第１熱交換器３０を凝縮器として機能させると共に、第２熱交換器４１，４２を蒸発器として機能させるように冷媒を循環させるか、又は、第１熱交換器３０を蒸発器として機能させると共に、第２熱交換器４１，４２を凝縮器として機能させるように冷媒を循環させることができる。 In other words, in the refrigerant unit 10, by controlling the four-way valve 60 to switch the flow direction of the refrigerant, the refrigerant can be circulated so that the first heat exchanger 30 functions as a condenser and the second heat exchangers 41 and 42 function as evaporators, or the refrigerant can be circulated so that the first heat exchanger 30 functions as an evaporator and the second heat exchangers 41 and 42 function as condensers.
図２、図４に示すように、第１熱交換器３０には、熱媒体回路を循環する熱媒体が流入又は流出する熱媒体配管３０１，３０２が接続され、第２熱交換器４１には、熱媒体回路を循環する熱媒体が流入又は流出する熱媒体配管４１１，４１２が接続され、第２熱交換器４２には、熱媒体回路を循環する熱媒体が流入又は流出する熱媒体配管４２１，４２２が接続されている。 As shown in Figures 2 and 4, the first heat exchanger 30 is connected to heat medium pipes 301 and 302 through which the heat medium circulating in the heat medium circuit flows in and out, the second heat exchanger 41 is connected to heat medium pipes 411 and 412 through which the heat medium circulating in the heat medium circuit flows in and out, and the second heat exchanger 42 is connected to heat medium pipes 421 and 422 through which the heat medium circulating in the heat medium circuit flows in and out.
第１熱交換器３０には、熱媒体回路を循環する熱媒体が、熱媒体配管３０１又は熱媒体配管３０２の一方から流入し第１熱交換器３０において冷媒と熱交換して熱媒体配管３０２又は熱媒体配管３０１の他方に流出する。 The heat medium circulating in the heat medium circuit flows into the first heat exchanger 30 from either the heat medium pipe 301 or the heat medium pipe 302, exchanges heat with the refrigerant in the first heat exchanger 30, and flows out of the other of the heat medium pipe 302 or the heat medium pipe 301.
同様に、第２熱交換器４１には、熱媒体回路を循環する熱媒体が、熱媒体配管４１１又は熱媒体配管４１２の何一方から流入し、第２熱交換器４１において冷媒と熱交換して熱媒体配管４１２又は熱媒体配管４１１の他方に流出する。 Similarly, the heat medium circulating in the heat medium circuit flows into the second heat exchanger 41 from either the heat medium piping 411 or the heat medium piping 412, exchanges heat with the refrigerant in the second heat exchanger 41, and flows out of the other of the heat medium piping 412 or the heat medium piping 411.
第２熱交換器４２には、熱媒体回路を循環する熱媒体が、熱媒体配管４２１又は熱媒体配管４２２の一方から流入し、第２熱交換器４２において冷媒と熱交換して熱媒体配管４２２又は熱媒体配管４２１の他方に流出する。 The heat medium circulating in the heat medium circuit flows into the second heat exchanger 42 from either the heat medium pipe 421 or the heat medium pipe 422, exchanges heat with the refrigerant in the second heat exchanger 42, and flows out of the other of the heat medium pipe 422 or the heat medium pipe 421.
（冷媒回路の各構成要素の接続関係について）
冷媒ユニット１０において、冷媒回路の各構成要素は、次のように接続されている（図５及び図６参照）。圧縮機２０の冷媒吸入口は、冷媒配管９４によってアキュムレータ２２と接続され、圧縮機２０の冷媒吐出口は、冷媒配管９１によって四方弁６０に接続されている。また、四方弁６０は、冷媒配管９２によって第１熱交換器３０の冷媒流入出口３０Ａと接続されると共に、冷媒配管９３によって流入出制御装置８０の接続部８３と接続されている。
(Regarding the connection relationship of each component of the refrigerant circuit)
In the refrigerant unit 10, the components of the refrigerant circuit are connected as follows (see FIGS. 5 and 6 ). The refrigerant suction port of the compressor 20 is connected to the accumulator 22 by a refrigerant pipe 94, and the refrigerant discharge port of the compressor 20 is connected to the four-way valve 60 by a refrigerant pipe 91. The four-way valve 60 is connected to the refrigerant inlet/outlet 30A of the first heat exchanger 30 by a refrigerant pipe 92, and is connected to the connection part 83 of the inlet/outlet control device 80 by a refrigerant pipe 93.
冷媒配管９１，９２，９３が四方弁６０に接続されているので、四方弁６０により冷媒の流通方向を切り替えることで、冷媒配管９１，９２を連通させて圧縮機２０から吐出された冷媒を第１熱交換器３０へ流す、又は、冷媒配管９１，９３を連通させて圧縮機２０から吐出された冷媒を流入出制御装置８０（電磁弁８１，８２）を介して第２熱交換器４１，４２に流すことができる。 Since the refrigerant pipes 91, 92, and 93 are connected to the four-way valve 60, the four-way valve 60 can be used to switch the flow direction of the refrigerant, allowing the refrigerant pipes 91 and 92 to communicate with each other and allow the refrigerant discharged from the compressor 20 to flow to the first heat exchanger 30, or allowing the refrigerant pipes 91 and 93 to communicate with each other and allow the refrigerant discharged from the compressor 20 to flow to the second heat exchangers 41 and 42 via the inflow/outflow control device 80 (solenoid valves 81 and 82).
第１熱交換器３０の冷媒流入出口３０Ｂは、冷媒配管５１によって減圧装置７０の接続部７３と接続されている。減圧装置７０の膨張弁７１は第２熱交換器４１の冷媒流入出口４１Ａと冷媒配管５２Ａによって接続される。同様に、減圧装置７０の膨張弁７２は第２熱交換器４２の冷媒流入出口４２Ａと冷媒配管５２Ｂによって接続される。 The refrigerant inlet/outlet 30B of the first heat exchanger 30 is connected to the connection part 73 of the pressure reducing device 70 by a refrigerant pipe 51. The expansion valve 71 of the pressure reducing device 70 is connected to the refrigerant inlet/outlet 41A of the second heat exchanger 41 by a refrigerant pipe 52A. Similarly, the expansion valve 72 of the pressure reducing device 70 is connected to the refrigerant inlet/outlet 42A of the second heat exchanger 42 by a refrigerant pipe 52B.
第２熱交換器４１の冷媒流入出口４１Ｂは接続部（不図示）を介して電磁弁８１と接続され、第２熱交換器４２の冷媒流入出口４２Ｂは接続部（不図示）を介して電磁弁８２と接続されている。電磁弁８１と電磁弁８２は共に接続部８３を介して冷媒配管９３に接続される。 The refrigerant inlet/outlet 41B of the second heat exchanger 41 is connected to the solenoid valve 81 via a connection part (not shown), and the refrigerant inlet/outlet 42B of the second heat exchanger 42 is connected to the solenoid valve 82 via a connection part (not shown). Both the solenoid valve 81 and the solenoid valve 82 are connected to the refrigerant piping 93 via a connection part 83.
前述のように、四方弁６０を制御して冷媒の流通方向を切り替えることで、第１熱交換器３０を凝縮器として機能させると共に、第２熱交換器４１，４２を蒸発器として機能させるように冷媒を循環させるか、又は、第１熱交換器３０を蒸発器として機能させると共に、第２熱交換器４１，４２を凝縮器として機能させるように冷媒を循環させることができる。つまり、冷媒ユニット１０では、第１熱交換器３０に高温冷媒が循環すると共に第２熱交換器４１，４２に低温冷媒が循環する場合と、第１熱交換器３０に低温冷媒が循環すると共に第２熱交換器４１，４２に高温冷媒が循環する場合とがあり、いずれの場合においても、第１熱交換器３０と第２熱交換器４１，４２との距離が近いほど、両者の間で熱移動が生じる。 As described above, by controlling the four-way valve 60 to switch the flow direction of the refrigerant, the refrigerant can be circulated so that the first heat exchanger 30 functions as a condenser and the second heat exchangers 41, 42 function as evaporators, or the first heat exchanger 30 functions as an evaporator and the second heat exchangers 41, 42 function as condensers. In other words, in the refrigerant unit 10, there are cases where a high-temperature refrigerant circulates through the first heat exchanger 30 and a low-temperature refrigerant circulates through the second heat exchangers 41, 42, and cases where a low-temperature refrigerant circulates through the first heat exchanger 30 and a high-temperature refrigerant circulates through the second heat exchangers 41, 42. In either case, the closer the distance between the first heat exchanger 30 and the second heat exchangers 41, 42, the more heat transfer occurs between them.
そこで、本実施形態では、第１熱交換器３０と第２熱交換器４１，４２との間に減圧装置７０を配置することで支持部材１２に各構成要素を効率よく配置しながら、第１熱交換器３０に対して第２熱交換器４１，４２を離間させている。これにより、第１熱交換器３０と第２熱交換器４１，４２との間の熱移動をできる限り抑制している。 In this embodiment, the pressure reducing device 70 is disposed between the first heat exchanger 30 and the second heat exchangers 41, 42, so that the components are efficiently disposed on the support member 12 while the second heat exchangers 41, 42 are spaced apart from the first heat exchanger 30. This suppresses heat transfer between the first heat exchanger 30 and the second heat exchangers 41, 42 as much as possible.
また、第２熱交換器４２は、第２熱交換器４１が配置されている分だけ第１熱交換器３０から更に離間しているので、第２熱交換器４１に比して第１熱交換器３０からの熱による影響が小さい。よって、温調対象に応じて第２熱交換器４１，４２を適宜用いることで、各温調対象における要求熱量を生成することができる。 In addition, the second heat exchanger 42 is further away from the first heat exchanger 30 by the distance where the second heat exchanger 41 is located, so it is less affected by the heat from the first heat exchanger 30 than the second heat exchanger 41. Therefore, by appropriately using the second heat exchangers 41 and 42 depending on the temperature control target, the required heat amount for each temperature control target can be generated.
（冷媒の流れについて）
次に、このような冷媒ユニット１０における冷媒の循環について図５及び図６を用いて説明する。冷媒ユニット１０では、例えば、空調目的又は温調対象に応じて、四方弁６０によって冷媒の循環方向を切替えることができる。
(Refrigerant flow)
5 and 6, the circulation of the refrigerant in the refrigerant unit 10 will be described. In the refrigerant unit 10, the circulation direction of the refrigerant can be switched by the four-way valve 60 according to, for example, the purpose of air conditioning or the target of temperature control.
（１）冷房運転時の冷媒の流れ
例えば、冷媒ユニット１０が用いられる空調装置において冷房運転が行われる場合には、冷媒は以下のように循環する（図５参照）。すなわち、冷媒は、圧縮機２０によって圧縮されて高圧のガス冷媒となって吐出され、冷媒配管９１を流通し、四方弁６０に流入する。高圧のガス冷媒は、四方弁６０から冷媒配管９２を流通し、第１熱交換器３０に流入する。
(1) Refrigerant flow during cooling operation For example, when cooling operation is performed in an air conditioner using the refrigerant unit 10, the refrigerant circulates as follows (see FIG. 5 ). That is, the refrigerant is compressed by the compressor 20 and discharged as high-pressure gas refrigerant, flows through the refrigerant pipe 91, and flows into the four-way valve 60. The high-pressure gas refrigerant flows from the four-way valve 60 through the refrigerant pipe 92, and flows into the first heat exchanger 30.
第１熱交換器３０に流入した冷媒は、第１熱交換器３０において他の熱媒体と熱交換することにより放熱した後に、第１熱交換器３０を流出して冷媒配管５１に流入し、減圧装置７０の接続部７３において分岐し、膨張弁７１，７２に向けて略均等に分流される。膨張弁７１，７２に流入した冷媒は、それぞれ減圧されて膨張し、低圧冷媒となって第２熱交換器４１，４２に流入する。 The refrigerant that flows into the first heat exchanger 30 dissipates heat by exchanging heat with other heat media in the first heat exchanger 30, then flows out of the first heat exchanger 30 into the refrigerant pipe 51, branches at the connection 73 of the pressure reducing device 70, and is divided approximately equally toward the expansion valves 71 and 72. The refrigerant that flows into the expansion valves 71 and 72 is decompressed and expanded, becoming a low-pressure refrigerant that flows into the second heat exchangers 41 and 42.
第２熱交換器４１，４２に流入した低圧冷媒は、第２熱交換器４１，４２において他の熱媒体と熱交換することにより吸熱した後に、第２熱交換器４１，４２から流出する。第２熱交換器４１，４２から流出した冷媒は、それぞれ電磁弁８１，８２を通過し、接続部８３で合流して冷媒配管９３に流れる。 The low-pressure refrigerant that flows into the second heat exchangers 41 and 42 absorbs heat by exchanging heat with other heat media in the second heat exchangers 41 and 42, and then flows out of the second heat exchangers 41 and 42. The refrigerant that flows out of the second heat exchangers 41 and 42 passes through solenoid valves 81 and 82, respectively, joins at the connection part 83, and flows into the refrigerant pipe 93.
冷媒配管９３に流入した冷媒は、再び四方弁６０に入り、四方弁６０を介してアキュムレータ２２に流入し、アキュムレータ２２から冷媒配管９４を介して圧縮機２０へ戻る。圧縮機２０に流入した冷媒は、再び圧縮され、上記循環を繰り返す。 The refrigerant that flows into the refrigerant pipe 93 re-enters the four-way valve 60, flows through the four-way valve 60 into the accumulator 22, and returns from the accumulator 22 to the compressor 20 through the refrigerant pipe 94. The refrigerant that flows into the compressor 20 is compressed again, and the above circulation is repeated.
（２）暖房運転時の冷媒の流れ
例えば、冷媒ユニット１０が用いられる空調装置において暖房運転が行われる場合には、冷媒は以下のように循環する（図６参照）。すなわち、冷媒は、圧縮機２０によって圧縮されて高圧のガス冷媒となって吐出され、冷媒配管９１を流通し、四方弁６０に流入する。高圧のガス冷媒は、四方弁から冷媒配管９３を流通し、流入出制御装置８０の接続部８３において分岐し、電磁弁８１，８２に向けて略均等に分流される。
(2) Refrigerant Flow During Heating Operation For example, when heating operation is performed in an air conditioner using the refrigerant unit 10, the refrigerant circulates as follows (see FIG. 6 ). That is, the refrigerant is compressed by the compressor 20 and discharged as high-pressure gas refrigerant, flows through the refrigerant pipe 91, and flows into the four-way valve 60. The high-pressure gas refrigerant flows from the four-way valve through the refrigerant pipe 93, branches at a connection portion 83 of the inflow/outflow control device 80, and is divided approximately equally toward the solenoid valves 81 and 82.
電磁弁８１，８２を流通した冷媒は、それぞれ第２熱交換器４１，４２に流入し、第２熱交換器４１，４２において他の熱媒体と熱交換することにより放熱した後に、第２熱交換器４１，４２を流出して、減圧装置７０の膨張弁７１，７２にそれぞれ流入する。膨張弁７１，７２において減圧されて膨張し、低圧冷媒となった冷媒は、接続部７３で合流して冷媒配管５１に流れ、第１熱交換器３０に流入する。 The refrigerant that has flowed through the solenoid valves 81 and 82 flows into the second heat exchangers 41 and 42, respectively, where it dissipates heat by exchanging heat with other heat media, and then flows out of the second heat exchangers 41 and 42 and into the expansion valves 71 and 72 of the pressure reducing device 70. The refrigerant that has been reduced in pressure and expanded in the expansion valves 71 and 72 and becomes a low-pressure refrigerant joins at the connection 73, flows into the refrigerant pipe 51, and flows into the first heat exchanger 30.
第１熱交換器３０に流入した冷媒は、第１熱交換器３０において他の熱媒体と熱交換することにより吸熱した後に、第１熱交換器３０から流出し、冷媒配管９２を流れて四方弁６０を経てアキュムレータ２２に流入し、冷媒配管９４を介して圧縮機２０へ戻る。圧縮機２０に流入した冷媒は、再び圧縮され、上記循環を繰り返す。 The refrigerant that flows into the first heat exchanger 30 absorbs heat by exchanging heat with another heat medium in the first heat exchanger 30, then flows out of the first heat exchanger 30, flows through the refrigerant pipe 92, passes through the four-way valve 60, flows into the accumulator 22, and returns to the compressor 20 via the refrigerant pipe 94. The refrigerant that flows into the compressor 20 is compressed again, and the above circulation is repeated.
以上述べた如く、本実施形態に係る冷媒ユニット１０によれば、冷媒回路の各構成要素が支持部材１２に支持されることでユニット化され、冷媒ユニット１０に備えられた各構成要素が互いに近接して配置されている。このような冷媒ユニット１０において、第１熱交換器３０と、第１熱交換器３０とは機能の異なる第２熱交換器４１，４２との間に減圧装置７０を配置することで、第１熱交換器３０と第２熱交換器４１，４２とを離間して配置している。 As described above, according to the refrigerant unit 10 of this embodiment, each component of the refrigerant circuit is supported by the support member 12 to form a unit, and each component provided in the refrigerant unit 10 is arranged close to each other. In such a refrigerant unit 10, the first heat exchanger 30 and the second heat exchangers 41, 42, which have a different function from the first heat exchanger 30, are arranged at a distance from each other by arranging the pressure reducing device 70 between them.
これにより、第１熱交換器３０、第２熱交換器４１，４２における熱移動を抑制して、熱移動に起因した熱損失を抑制することができる。つまり、各熱交換器における高温冷媒の温度低下や低温冷媒の温度上昇を抑制し、冷媒ユニット１０が適用される熱管理システムの性能維持を図ることができる。 This makes it possible to suppress heat transfer in the first heat exchanger 30 and the second heat exchangers 41 and 42, thereby suppressing heat loss caused by heat transfer. In other words, it is possible to suppress the temperature drop of the high-temperature refrigerant and the temperature rise of the low-temperature refrigerant in each heat exchanger, thereby maintaining the performance of the thermal management system to which the refrigerant unit 10 is applied.
特に、第２熱交換器４１は、減圧装置７０を挟んで第１熱交換器３０の反対側に位置しているが、第２熱交換器４２は、減圧装置７０に加えて第２熱交換器４１が配置されている分だけ第１熱交換器３０から更に離間しているので、第２熱交換器４１に比して第１熱交換器３０からの熱による影響が小さい。このように、冷媒ユニット１０では、第１熱交換器３０による熱の影響の異なる２つの第２熱交換器４１，４２を、温調対象に応じて適宜用いることで、各温調対象における要求熱量を生成することができる。 In particular, the second heat exchanger 41 is located on the opposite side of the pressure reducing device 70 from the first heat exchanger 30, but the second heat exchanger 42 is further away from the first heat exchanger 30 by the amount of the pressure reducing device 70 and the second heat exchanger 41, so it is less affected by the heat from the first heat exchanger 30 than the second heat exchanger 41. In this way, in the refrigerant unit 10, the two second heat exchangers 41, 42, which are differently affected by the heat from the first heat exchanger 30, are appropriately used according to the temperature control target, so that the required heat amount for each temperature control target can be generated.
また、支持部材１２の固定壁１６に貫通孔１６１，１６２，１６３が設けられ、これら貫通孔１６１，１６２，１６３に、第２熱交換器４１，４２と電磁弁８１，８２との接続部（不図示）、第１熱交換器３０と冷媒配管９２との接続部３５がそれぞれ挿入されている。つまり、第２熱交換器４１，４２と電磁弁８１，８２との接続部、第１熱交換器３０と冷媒配管９２との接続部３５を、固定壁１６を貫通するように設けられている。 In addition, through holes 161, 162, and 163 are provided in the fixed wall 16 of the support member 12, and the connection parts (not shown) between the second heat exchangers 41, 42 and the solenoid valves 81, 82 and the connection part 35 between the first heat exchanger 30 and the refrigerant piping 92 are inserted into these through holes 161, 162, and 163. In other words, the connection parts between the second heat exchangers 41, 42 and the solenoid valves 81, 82 and the connection part 35 between the first heat exchanger 30 and the refrigerant piping 92 are provided to penetrate the fixed wall 16.
これにより、第２熱交換器４１，４２と電磁弁８１，８２との間における冷媒流路の長さ、及び、第１熱交換器３０と冷媒配管９２との間における冷媒流路の長さを、可能な限り短くすることができる。このように、冷媒流路を固定壁１６に貫通させることで、固定壁１６を跨いだり迂回させたりして設けることに比して、冷媒流路をはるかに短くすることができると共に、冷媒流路が支持部材１２の高さ及び幅からはみ出すことがない。したがって、冷媒ユニットの小型化を図ることができると共に、冷媒が流れる流路における冷媒の熱損失や圧力損失を抑えることができる。 This allows the length of the refrigerant flow path between the second heat exchangers 41, 42 and the solenoid valves 81, 82, and the length of the refrigerant flow path between the first heat exchanger 30 and the refrigerant piping 92 to be as short as possible. By penetrating the refrigerant flow path through the fixed wall 16 in this way, the refrigerant flow path can be made much shorter than if it were provided by straddling or bypassing the fixed wall 16, and the refrigerant flow path does not extend beyond the height and width of the support member 12. This allows the refrigerant unit to be made smaller, and reduces heat loss and pressure loss of the refrigerant in the flow path through which the refrigerant flows.
なお、支持部材１２と、第２熱交換器４１，４２と電磁弁８１，８２との接続部（不図示）、第１熱交換器３０と冷媒配管９２との接続部３５とは、それぞれ別個独立の構成である。また、貫通孔１６１，１６２，１６３の周縁と各接続部とが接していないことから、冷媒流路（各接続部）と固定壁１６との間の熱移動が抑制される。 The support member 12, the connection parts (not shown) between the second heat exchangers 41, 42 and the solenoid valves 81, 82, and the connection part 35 between the first heat exchanger 30 and the refrigerant piping 92 are each separate and independent configurations. In addition, since the periphery of the through holes 161, 162, 163 does not contact each connection part, heat transfer between the refrigerant flow path (each connection part) and the fixed wall 16 is suppressed.
このように本実施形態によれば、冷媒回路の構成要素をユニット化した冷媒ユニットにおいて、各構成要素を接続する冷媒流路を可能な限り短くして冷媒ユニットの小型化を図ることができる。 In this way, according to this embodiment, in a refrigerant unit in which the components of a refrigerant circuit are unitized, the refrigerant flow paths connecting each component can be made as short as possible, thereby making the refrigerant unit smaller.
以上、本発明の実施の形態について図面を参照して詳述してきたが、具体的な構成は上述した実施形態に限られるものではなく、本発明の要旨を逸脱しない範囲の設計の変更等があっても本発明に含まれる。 The above describes the embodiments of the present invention in detail with reference to the drawings, but the specific configuration is not limited to the above-mentioned embodiments, and the present invention also includes design changes that do not deviate from the gist of the present invention.
