Description

本発明は、圧縮機から吐出された冷媒の圧力脈動を低減させる消音器を備える車両用空調装置に関するものである。   The present invention relates to a vehicle air conditioner including a silencer that reduces pressure pulsation of refrigerant discharged from a compressor.

車両用空調装置においては、圧縮機から吐出された冷媒は圧縮機の気筒数に応じた圧力脈動を持ち、その圧力脈動が加振力となって凝縮器の振動を励起し、車室内騒音となる。そこで、従来の車両用空調装置は、圧縮機と凝縮器との間に配置された消音器により圧力脈動を低減して、加振力の低減を図っている（例えば、特許文献１参照）。
特開２０００−７３７３７号公報 In a vehicle air conditioner, the refrigerant discharged from the compressor has a pressure pulsation corresponding to the number of cylinders of the compressor, and the pressure pulsation serves as an excitation force to excite the vibration of the condenser. Become. Therefore, the conventional vehicle air conditioner reduces the pressure pulsation with a silencer disposed between the compressor and the condenser to reduce the excitation force (see, for example, Patent Document 1).
JP 2000-73737 A

しかしながら、より低周波数域（例えば、８００Ｈｚ以下）での圧力脈動を低減する場合、消音器の長手方向の長さが増加してしまうが、近年のエンジンルームの省スペース化により、消音器の長手方向寸法が増加した場合にそれを搭載するスペースを確保するのが困難になってきている。   However, when the pressure pulsation in a lower frequency range (for example, 800 Hz or less) is reduced, the length of the silencer in the longitudinal direction increases. However, due to space saving in the engine room in recent years, the length of the silencer is increased. When the directional dimension increases, it becomes difficult to secure a space for mounting it.

本発明は上記点に鑑みて、長手方向寸法が増加した消音器の搭載を可能にして、より低周波数域での圧力脈動を低減することを目的とする。   In view of the above points, an object of the present invention is to enable mounting of a silencer having an increased longitudinal dimension, and to reduce pressure pulsation in a lower frequency range.

本発明は、冷媒の圧力脈動を低減させる消音器（２）を、凝縮器（３）に隣接して配置して凝縮器（３）に接合することを特徴とする。   The present invention is characterized in that the silencer (2) for reducing the pressure pulsation of the refrigerant is disposed adjacent to the condenser (3) and joined to the condenser (3).

長手方向寸法が大きい凝縮器（３）の近傍では、長手方向寸法が増加した消音器（２）の搭載スペースの確保が容易である。したがって、凝縮器（３）に隣接して消音器（２）を配置すれば、長手方向寸法が増加した消音器（２）の搭載が可能となり、より低周波数域での圧力脈動を低減することができる。   In the vicinity of the condenser (3) having a large longitudinal dimension, it is easy to secure a mounting space for the silencer (2) having an increased longitudinal dimension. Therefore, if the silencer (2) is disposed adjacent to the condenser (3), it is possible to mount the silencer (2) having an increased longitudinal dimension, and to reduce pressure pulsation in a lower frequency range. Can do.

この場合、凝縮器（３）の一端側に消音器（２）を接合し、凝縮器（３）の他端側に気液分離器（４）を接合することができる。   In this case, the silencer (2) can be joined to one end side of the condenser (3), and the gas-liquid separator (4) can be joined to the other end side of the condenser (3).

このようにすれば、凝縮器（３）の重心位置を中央に近付け、取付けゴムの偏った変形を抑制することができる。したがって、振動が生じた際も、バランスよく取付けゴムに荷重がかかるようになり、適切な防振効果が得られる。   If it does in this way, the gravity center position of a condenser (3) can be brought close to a center, and the deformation | transformation which the mounting rubber biased can be suppressed. Therefore, even when vibration occurs, a load is applied to the mounting rubber in a well-balanced manner, and an appropriate anti-vibration effect can be obtained.

また、消音器（２）は、膨張式消音器とサイドブランチ式消音器とを組み合わせたものとすることができる。このようにすれば、圧力脈動を低減したい周波数域や減衰率の調整が容易である。   Moreover, the silencer (2) can be a combination of an expansion silencer and a side branch silencer. In this way, it is easy to adjust the frequency range and attenuation rate where pressure pulsation is desired to be reduced.

また、消音器（２）と凝縮器（３）を、２箇所以上で接合することができる。このようにすれば、耐震強度を高くすることができる。   Moreover, the silencer (2) and the condenser (3) can be joined at two or more locations. In this way, the seismic strength can be increased.

また、消音器（２）を、凝縮器（３）のうち過冷却部（３２）を除く部位に接合することができる。   Moreover, a silencer (2) can be joined to the site | part except a supercooling part (32) among condensers (3).

このように、凝縮器（３）のうち最も温度が低い過冷却部（３２）を避けて消音器（２）を接合することにより、消音器（２）から凝縮器（３）への熱伝達を抑制することができる。   In this way, heat transfer from the silencer (2) to the condenser (3) is achieved by joining the silencer (2) while avoiding the supercooling section (32) having the lowest temperature among the condenser (3). Can be suppressed.

また、消音器（２）内の底部と凝縮器（３）内の冷媒通路を連通することができる。このようにすれば、消音器（２）の底部に溜まった圧縮機潤滑用オイルを冷媒中に戻すことができる。   Moreover, the bottom part in a silencer (2) and the refrigerant path in a condenser (3) can be connected. If it does in this way, the oil for compressor lubrication collected at the bottom of silencer (2) can be returned in a refrigerant.

なお、特許請求の範囲およびこの欄で記載した各手段の括弧内の符号は、後述する実施形態に記載の具体的手段との対応関係を示すものである。   In addition, the code | symbol in the bracket | parenthesis of each means described in a claim and this column shows the correspondence with the specific means as described in embodiment mentioned later.

（第１実施形態）
本発明の第１実施形態について説明する。図１は本実施形態に係る車両空調用装置の構成を示す図、図２は図１の消音器の模式的な断面図である。なお、図１中の矢印は、消音器、凝縮器、および気液分離器の、車両搭載状態における天地左右方向を示している。 (First embodiment)
A first embodiment of the present invention will be described. FIG. 1 is a diagram showing a configuration of a vehicle air-conditioning apparatus according to this embodiment, and FIG. 2 is a schematic cross-sectional view of the silencer of FIG. In addition, the arrow in FIG. 1 has shown the top-bottom left-right direction in the vehicle mounting state of the silencer, the condenser, and the gas-liquid separator.

図１、図２に示すように、圧縮機１は図示しない内燃機関によって駆動されて冷媒を圧縮し吐出する。圧縮機１から吐出された高温・高圧の気相冷媒は、消音器２に流入して、冷媒の圧力脈動が低減される。   As shown in FIGS. 1 and 2, the compressor 1 is driven by an internal combustion engine (not shown) to compress and discharge the refrigerant. The high-temperature and high-pressure gas-phase refrigerant discharged from the compressor 1 flows into the silencer 2, and the pressure pulsation of the refrigerant is reduced.

この消音器２を通過した冷媒は、冷媒と外気との熱交換を行う凝縮器３に流入する。より詳細には、凝縮器３は、気相冷媒と外気との熱交換により気相冷媒を凝縮させる凝縮部３１と、凝縮された冷媒と外気との熱交換により冷媒をさらに冷却する過冷却部３２を備えており、消音器２を通過した冷媒は凝縮部３１に流入する。   The refrigerant that has passed through the silencer 2 flows into the condenser 3 that performs heat exchange between the refrigerant and the outside air. More specifically, the condenser 3 includes a condensing unit 31 that condenses the gas-phase refrigerant by heat exchange between the gas-phase refrigerant and the outside air, and a supercooling unit that further cools the refrigerant by heat exchange between the condensed refrigerant and the outside air. The refrigerant that has passed through the silencer 2 flows into the condensing unit 31.

凝縮部３１を通過した冷媒は、気液分離器４にて気相冷媒と液冷媒とに分離される。この気液分離器４で分離された液冷媒が過冷却部３２に流入する。過冷却部３２を通過した冷媒は、膨張弁５および蒸発器６を通過して圧縮機１に戻される。   The refrigerant that has passed through the condensing unit 31 is separated into a gas-phase refrigerant and a liquid refrigerant by the gas-liquid separator 4. The liquid refrigerant separated by the gas-liquid separator 4 flows into the supercooling unit 32. The refrigerant that has passed through the supercooling unit 32 passes through the expansion valve 5 and the evaporator 6 and is returned to the compressor 1.

膨張弁５は、蒸発器６の出口冷媒の過熱度が予め設定した所定値となるように弁開度を調整して、冷媒流量を調整するものである。蒸発器６は、冷媒と車室内空気との熱交換により車室内空気を冷却するものである。   The expansion valve 5 adjusts the flow rate of the refrigerant by adjusting the valve opening so that the degree of superheat of the outlet refrigerant of the evaporator 6 becomes a predetermined value set in advance. The evaporator 6 cools the passenger compartment air by heat exchange between the refrigerant and the passenger compartment air.

消音器２は、いわゆるサイドブランチ式消音器であり、圧縮機１に接続される入口部２１から凝縮器３に接続される出口部２２に向かって冷媒が流れる主通路部２３と、この主通路部２３から分岐して先端が行き止りとなる分岐部２４とを備えている。そして、分岐部２４に進んだ圧力波は、その底部にて反射波を生じ、主通路部２３を進む圧力波と合流する。その際、分岐部２４は経路が長いため、脈動の位相がずれる。その位相差を利用して２つの圧力波を干渉させて脈動を低減するようになっている。   The silencer 2 is a so-called side-branch silencer, and a main passage portion 23 through which refrigerant flows from an inlet portion 21 connected to the compressor 1 toward an outlet portion 22 connected to the condenser 3, and the main passage. And a branch part 24 that branches off from the part 23 and has a dead end at the tip. And the pressure wave which advanced to the branch part 24 produces a reflected wave in the bottom part, and merges with the pressure wave which advances the main channel | path part 23. FIG. At that time, the branching section 24 has a long path, so that the phase of pulsation is shifted. Using the phase difference, two pressure waves interfere with each other to reduce pulsation.

ここで、主通路部２３から分岐部２４の底部までの寸法である分岐部長さＬを４００ｍｍ、分岐部２４の内径φｄを３６ｍｍにした場合、８００Ｈｚ付近において大きな騒音低減効果が得られる。   Here, when the branch portion length L, which is the dimension from the main passage portion 23 to the bottom portion of the branch portion 24, is 400 mm and the inner diameter φd of the branch portion 24 is 36 mm, a large noise reduction effect is obtained in the vicinity of 800 Hz.

凝縮器３は直方体であり、消音器２および気液分離器４は円筒形状になっている。消音器２の天地方向の寸法は、凝縮器３の天地方向寸法よりも短く、より詳細には、凝縮部３１の天地方向寸法と略等しくなっている。消音器２の外径は、気液分離器４と同等以下である。   The condenser 3 is a rectangular parallelepiped, and the silencer 2 and the gas-liquid separator 4 have a cylindrical shape. The vertical dimension of the silencer 2 is shorter than the vertical dimension of the condenser 3, and more specifically, is substantially equal to the vertical dimension of the condenser 31. The outer diameter of the silencer 2 is equal to or less than that of the gas-liquid separator 4.

そして、消音器２は、凝縮器３における車両左右方向の一端の側面に密着するように（例えば、凝縮器３の周囲１０ｃｍ以内に収まるように）、また、長手方向が天地方向になるように配置されている。   The silencer 2 is in close contact with the side surface of one end of the condenser 3 in the left-right direction of the vehicle (for example, within 10 cm around the condenser 3), and the longitudinal direction is the vertical direction. Has been placed.

消音器２と凝縮器３は、ボルトまたは溶接等にて接合されている。消音器２と凝縮器３の接合部は、１箇所でもよいが、耐震強度を高くするために２箇所以上にするのが望ましい。また、消音器２から過冷却部３２への熱伝達が行われないように、過冷却部３２には消音器２との接合部を設けていない。   The silencer 2 and the condenser 3 are joined by bolts or welding. Although the joint part of the silencer 2 and the condenser 3 may be one place, it is desirable to use two or more places in order to increase the earthquake resistance. Further, the supercooling section 32 is not provided with a joint portion with the silencer 2 so that heat transfer from the silencer 2 to the supercooling section 32 is not performed.

気液分離器４は、凝縮器３における車両左右方向の他端の側面に密着し、また、長手方向が天地方向になるように配置されている。気液分離器４と凝縮器３は、ボルトまたは溶接等にて接合されている。   The gas-liquid separator 4 is disposed in close contact with the side surface of the other end of the condenser 3 in the left-right direction of the vehicle, and the longitudinal direction is the vertical direction. The gas-liquid separator 4 and the condenser 3 are joined by bolts or welding.

消音器２および気液分離器４が一体化された凝縮器３は、４つのブラケット３３を利用して車体に固定される。なお、ブラケット３３には、防振のために図示しない取付けゴムが装着されている。   The condenser 3 in which the silencer 2 and the gas-liquid separator 4 are integrated is fixed to the vehicle body using four brackets 33. Note that a mounting rubber (not shown) is attached to the bracket 33 for vibration isolation.

ところで、凝縮器３は天地方向および横方向（本例では、車両左右方向）の寸法が大きいため、凝縮器３の近傍では、長手方向寸法が増加した消音器２の搭載スペースの確保が容易である。したがって、本実施形態のように、凝縮器３に隣接して消音器２を配置すれば、長手方向寸法が増加した消音器２の搭載が可能となり、より低周波数域での圧力脈動を低減することができる。   By the way, since the condenser 3 has large dimensions in the vertical direction and the horizontal direction (in this example, the vehicle left-right direction), it is easy to secure a mounting space for the silencer 2 whose longitudinal dimension has increased in the vicinity of the condenser 3. is there. Therefore, if the silencer 2 is arranged adjacent to the condenser 3 as in the present embodiment, the silencer 2 having an increased longitudinal dimension can be mounted, and pressure pulsation in a lower frequency range is reduced. be able to.

また、凝縮器３の一端側に消音器２を配置し、凝縮器３の他端側に気液分離器４を配置しているため、凝縮器３の重心位置を中央に近付け、取付けゴムの偏った変形を抑制することができる。したがって、振動が生じた際も、バランスよく取付けゴムに荷重がかかるようになり、適切な防振効果が得られる。   Further, since the silencer 2 is disposed on one end side of the condenser 3 and the gas-liquid separator 4 is disposed on the other end side of the condenser 3, the position of the center of gravity of the condenser 3 is brought closer to the center, Uneven deformation can be suppressed. Therefore, even when vibration occurs, a load is applied to the mounting rubber in a well-balanced manner, and an appropriate anti-vibration effect can be obtained.

（第２実施形態）
本発明の第２実施形態について説明する。図３は本実施形態に係る車両空調用装置における消音器の模式的な断面図である。第１実施形態と同一もしくは均等部分には同一の符号を付し、その説明を省略する。 (Second Embodiment)
A second embodiment of the present invention will be described. FIG. 3 is a schematic cross-sectional view of a silencer in the vehicle air-conditioning apparatus according to the present embodiment. The same or equivalent parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

第１実施形態では、サイドブランチ式の消音器２を用いたが、本実施形態では、サイドブランチ式消音器と膨張式消音器を組合せた消音器２を用いている。因みに、膨張式消音器は、冷媒通路の断面積を拡大し縮小することで、その変化部（縮小部）において圧力波を反射させ干渉させて圧力脈動を低減するものである。   In the first embodiment, the side branch type silencer 2 is used, but in this embodiment, the silencer 2 in which the side branch type silencer and the expansion silencer are combined is used. By the way, the expansion silencer expands and reduces the cross-sectional area of the refrigerant passage, and reflects and interferes with the pressure wave at the changing portion (reducing portion) to reduce pressure pulsation.

図３に示すように、消音器２は円筒形状になっており、長手方向の中間部に設けた仕切り板２５により、内部空間が分岐部２４と膨張室２６に分離されている。但し、分岐部２４と膨張室２６は、仕切り板２５に設けた絞り穴２７により連通している。なお、膨張室２６の部分が膨張式消音器に相当する。また、分岐部２４の部分がサイドブランチ式消音器に相当する。   As shown in FIG. 3, the silencer 2 has a cylindrical shape, and an internal space is separated into a branch portion 24 and an expansion chamber 26 by a partition plate 25 provided at an intermediate portion in the longitudinal direction. However, the branch portion 24 and the expansion chamber 26 communicate with each other through a throttle hole 27 provided in the partition plate 25. The portion of the expansion chamber 26 corresponds to an expansion silencer. Further, the branching portion 24 corresponds to a side branch type silencer.

本実施形態によると、仕切り板２５の位置を変えることにより、圧力脈動を低減したい周波数域や減衰率を調整することができる。   According to the present embodiment, by changing the position of the partition plate 25, it is possible to adjust the frequency range and the attenuation rate where pressure pulsation is desired to be reduced.

In each of the above embodiments, an oil return hole is provided to communicate the bottom portion in the silencer 2 and the refrigerant passage in the condenser 3 so that the compressor lubricating oil accumulated at the bottom portion of the silencer 2 is returned to the refrigerant. It may be. At this time, the oil return hole is preferably provided at a position within 5 cm from the bottom surface of the silencer 2. Further, it is desirable that the compressor lubricating oil collected at the bottom of the silencer 2 is returned to the condensing unit 31 instead of the supercooling unit 32.

上記各実施形態において、消音器２と凝縮器３の接合部に、防振のために例えばゴム製の弾性部材を設けるのが望ましい。   In each of the above embodiments, it is desirable to provide, for example, an elastic member made of rubber at the joint between the silencer 2 and the condenser 3 for vibration isolation.
