　本発明は、送風機ユニットと対象空気熱交換器ユニットとを有する空気調和装置に関する。 The present invention relates to an air conditioner having a blower unit and a target air heat exchanger unit.
　従来、送風機ユニットと熱交換器ユニットとを有する空気調和装置が知られている（たとえば、特許文献１参照）。特許文献１には、機能別にユニット化された所望のユニットを自在に組み合わせる構成の空気調和装置が開示されている。 Conventionally, an air conditioner having a blower unit and a heat exchanger unit is known (for example, see Patent Document 1). Patent Literature 1 discloses an air conditioner configured to freely combine desired units that are unitized by function.
特開平０６－２２１６１７号公報Japanese Patent Laid-Open No. 06-221617
　特許文献１に開示されている従来の空気調和装置では、送風機は、熱交換器よりも風路の下流側に配置されている。このため、熱交換器で生じた結露水は、風路の下流側に配置された送風機に向かって吹き飛び、送風機に結露水が付着することがある。したがって、従来の空気調和装置では、熱交換器よりも風路の下流側に配置されている送風機に、防水対策を施す必要がある。送風機に防水対策を施すことは、送風機の構造を複雑にし、高コストであった。 In the conventional air conditioner disclosed in Patent Document 1, the blower is arranged on the downstream side of the air passage with respect to the heat exchanger. For this reason, the dew condensation water produced in the heat exchanger blows off toward the blower arranged on the downstream side of the air passage, and the dew condensation water may adhere to the blower. Therefore, in the conventional air conditioning apparatus, it is necessary to take a waterproof measure for the blower disposed on the downstream side of the air path from the heat exchanger. Applying waterproof measures to the blower complicates the structure of the blower and is expensive.
　本発明は、上記課題を解決するためのものであり、熱交換器で生じた結露水が送風機に付着することを防止した空気調和装置を提供することを目的とする。 This invention is for solving the said subject, and it aims at providing the air conditioning apparatus which prevented the dew condensation water produced with the heat exchanger adhering to a fan.

It is.
　本発明に係る空気調和装置によれば、送風機ユニットは、対象空気熱交換器ユニットよりも送風機の生成する風の流れ方向で上流側に配置された。このため、対象空気熱交換器ユニットに収容された対象空気熱交換器で生じた結露水が、送風機ユニットに収容された送風機に付着することを防止した空気調和装置を得ることができる。 According to the air conditioner according to the present invention, the blower unit is disposed upstream of the target air heat exchanger unit in the flow direction of the wind generated by the blower. For this reason, the air conditioning apparatus which prevented that the dew condensation water produced with the object air heat exchanger accommodated in the object air heat exchanger unit adheres to the air blower accommodated in the air blower unit can be obtained.

FIG. 1 is a diagram schematically illustrating an example of a configuration of an air-conditioning apparatus 30 according to Embodiment 1 of the present invention. FIG. 2 is a diagram schematically illustrating an example of the arrangement of the blower unit 10, the target air heat exchanger unit 20, and the heat source side unit 100 in the air-conditioning apparatus 30 according to Embodiment 1 of the present invention.
An air conditioner 30 shown in FIG. 1 performs air conditioning of an air conditioning target room 50 such as a room inside a building or a house. The air conditioner 30 is applied to, for example, a ceiling-embedded air conditioner such as a residential packaged air conditioner or a building multi air conditioner.
　空気調和装置３０は、たとえば、対象空気熱交換器ユニット２０と熱源側ユニット１００とが冷媒配管１２０で接続されて冷媒が循環する冷凍サイクル回路を備えている。 The air conditioner 30 includes, for example, a refrigeration cycle circuit in which the target air heat exchanger unit 20 and the heat source unit 100 are connected by a refrigerant pipe 120 and the refrigerant circulates.
　熱源側ユニット１００は、たとえば、屋外に配置されるものである。熱源側ユニット１００は、圧縮機１０２と、流路切替装置１０４と、熱源側熱交換器１０６と、制御器１１０と、を有している。また、熱源側ユニット１００は、熱源側熱交換器１０６への送風を行う送風機１０８を有している。
　圧縮機１０２は、冷媒配管１２０を流れる冷媒を圧縮する。流路切替装置１０４は、冷媒配管１２０を流れる冷媒の流れを冷房時と暖房時とで切り替える。熱源側熱交換器１０６は、冷媒配管１２０を流れる冷媒と外気とで熱交換させる。制御器１１０は、空気調和装置３０の全体の制御を司る。制御器１１０は、ＣＰＵ、ＲＯＭ、ＲＡＭ、Ｉ／Ｏポートなどを備えたマイコンを有している。 The heat source side unit 100 is arranged outdoors, for example. The heat source side unit 100 includes a compressor 102, a flow path switching device 104, a heat source side heat exchanger 106, and a controller 110. The heat source side unit 100 includes a blower 108 that blows air to the heat source side heat exchanger 106.
The compressor 102 compresses the refrigerant flowing through the refrigerant pipe 120. The flow path switching device 104 switches the flow of the refrigerant flowing through the refrigerant pipe 120 between cooling and heating. The heat source side heat exchanger 106 exchanges heat between the refrigerant flowing through the refrigerant pipe 120 and the outside air. The controller 110 governs overall control of the air conditioner 30. The controller 110 has a microcomputer equipped with a CPU, ROM, RAM, I / O port, and the like.
　対象空気熱交換器ユニット２０は、たとえば、建物あるいは家屋の内部の設備室６０に配置される。設備室６０は、たとえば、建物あるいは家屋の内部における空調対象室５０の天井の上方の天井裏に形成された空間である。つまり、対象空気熱交換器ユニット２０は、天井裏に配置されている。
　対象空気熱交換器ユニット２０は、絞り装置２２と、対象空気熱交換器２１と、を有している。絞り装置２２は、冷媒配管１２０を流れる冷媒の圧力を調整する。なお、絞り装置２２は、対象空気熱交換器ユニット２０に収容されず、熱源側ユニット１００に収容されてもよい。対象空気熱交換器２１は、冷媒配管１２０を流れる冷媒と空調対象室５０の室内空気から風路４０に流入させた対象空気とを熱交換させる。 The target air heat exchanger unit 20 is disposed, for example, in an equipment room 60 inside a building or a house. The facility room 60 is, for example, a space formed in the back of the ceiling above the ceiling of the air-conditioning target room 50 in a building or house. That is, the target air heat exchanger unit 20 is disposed behind the ceiling.
The target air heat exchanger unit 20 includes a throttle device 22 and a target air heat exchanger 21. The expansion device 22 adjusts the pressure of the refrigerant flowing through the refrigerant pipe 120. The expansion device 22 may be accommodated in the heat source side unit 100 instead of being accommodated in the target air heat exchanger unit 20. The target air heat exchanger 21 exchanges heat between the refrigerant flowing through the refrigerant pipe 120 and the target air that has flowed into the air passage 40 from the room air in the air conditioning target chamber 50.
　また、空気調和装置３０は、送風機ユニット１０を有している。送風機ユニット１０は、たとえば、設備室６０に配置される。つまり、送風機ユニット１０は、対象空気熱交換器ユニット２０と共に天井裏に配置されている。送風機ユニット１０は、送風機としてのシロッコファン１１と、シロッコファン１１を回転駆動する図示しないモータと、モータの回転数を制御する制御器１２と、を有している。制御器１２は、ＣＰＵ、ＲＯＭ、ＲＡＭ、Ｉ／Ｏポートなどを備えたマイコンを有している。
　なお、送風機ユニット１０は、送風機としてシロッコファンでなく、プロペラファンなどを収容してもよい。 The air conditioner 30 includes the blower unit 10. The blower unit 10 is disposed in the equipment room 60, for example. That is, the blower unit 10 is arranged on the back of the ceiling together with the target air heat exchanger unit 20. The blower unit 10 includes a sirocco fan 11 as a blower, a motor (not shown) that rotationally drives the sirocco fan 11, and a controller 12 that controls the rotational speed of the motor. The controller 12 has a microcomputer including a CPU, ROM, RAM, I / O port, and the like.
The blower unit 10 may house a propeller fan or the like instead of a sirocco fan as a blower.
　空調対象室５０と送風機ユニット１０とは、ダクト５４を介して連通している。送風機ユニット１０と対象空気熱交換器ユニット２０とは、ダクト部材１を介して連通している。対象空気熱交換器ユニット２０と空調対象室５０とは、ダクト５６を介して連通している。ダクト５６には、対象空気熱交換器ユニット２０から流出する対象空気が流れる。ダクト５６は、建物あるいは家屋の内部の空気調和を実施する空調対象室５０の上部まで延設されている。
　ダクト部材１および２つのダクト５４、５６は、たとえば、フレキシブルダクトである。 The air conditioning target chamber 50 and the blower unit 10 communicate with each other via a duct 54. The blower unit 10 and the target air heat exchanger unit 20 communicate with each other via the duct member 1. The target air heat exchanger unit 20 and the air conditioning target chamber 50 communicate with each other via a duct 56. The target air flowing out from the target air heat exchanger unit 20 flows through the duct 56. The duct 56 is extended to the upper part of the air-conditioning target room 50 that performs air conditioning inside the building or house.
The duct member 1 and the two ducts 54 and 56 are, for example, flexible ducts.
　ダクト部材１と２つのダクト５４、５６と送風機ユニット１０と対象空気熱交換器ユニット２０とは、空調対象室５０の室内空気を流入させた対象空気が流れる風路４０を構成している。風路４０は、設備室６０に配置されている。つまり。風路４０は、建物あるいは家屋の天井裏に延設されている。送風機ユニット１０、ダクト部材１および対象空気熱交換器ユニット２０は、風路４０の途中に配置されている。
　送風機ユニット１０は、対象空気熱交換器ユニット２０よりも風路４０においてシロッコファン１１が生成する風の流れ方向で上流側に配置されている。 The duct member 1, the two ducts 54 and 56, the blower unit 10, and the target air heat exchanger unit 20 constitute an air passage 40 through which target air into which room air in the air-conditioning target room 50 is introduced flows. The air passage 40 is disposed in the equipment room 60. In other words. The air path 40 is extended behind the ceiling of a building or a house. The blower unit 10, the duct member 1, and the target air heat exchanger unit 20 are arranged in the middle of the air passage 40.
The blower unit 10 is disposed upstream of the target air heat exchanger unit 20 in the air flow direction of the wind generated by the sirocco fan 11 in the air path 40.
　送風機ユニット１０が動作すると、空調対象室５０の空気が、風路４０の入口である吸入口５２を介してダクト５４に吸い込まれる。ダクト５４に吸い込まれた対象空気は、送風機ユニット１０およびダクト部材１を介して対象空気熱交換器ユニット２０に流入する。対象空気熱交換器ユニット２０に流入した対象空気は、対象空気熱交換器２１で冷媒と熱交換される。対象空気熱交換器２１で熱交換された空調空気は、ダクト５６を流れて風路４０の出口である吹出口５８から空調対象室５０に吹き出される。 When the blower unit 10 operates, the air in the air-conditioning target chamber 50 is sucked into the duct 54 through the suction port 52 that is the inlet of the air passage 40. The target air sucked into the duct 54 flows into the target air heat exchanger unit 20 via the blower unit 10 and the duct member 1. The target air that has flowed into the target air heat exchanger unit 20 is heat-exchanged with the refrigerant in the target air heat exchanger 21. The conditioned air heat-exchanged by the target air heat exchanger 21 flows through the duct 56 and is blown out from the air outlet 58 that is the outlet of the air passage 40 to the air-conditioning target chamber 50.
　図３は、本発明の実施の形態１に係る送風機ユニット１０および対象空気熱交換器ユニット２０の構成の一例を示す概略図である。
　図３に示すように、送風機ユニット１０と対象空気熱交換器ユニット２０とは、ダクト部材１で接続されている。
　ダクト部材１は、たとえば、フレキシブルダクトである。このため、ダクト部材１が屈曲あるいは延伸自在であり、送風機ユニット１０および対象空気熱交換器ユニット２０の配置の自由度が向上される。
　送風機ユニット１０は、対象空気熱交換器ユニット２０よりも風路４０におけるシロッコファン１１が生成する風の流れ方向で上流側に配置されている。 FIG. 3 is a schematic diagram illustrating an example of the configuration of the blower unit 10 and the target air heat exchanger unit 20 according to Embodiment 1 of the present invention.
As shown in FIG. 3, the blower unit 10 and the target air heat exchanger unit 20 are connected by a duct member 1.
The duct member 1 is, for example, a flexible duct. For this reason, the duct member 1 can be bent or extended freely, and the degree of freedom of arrangement of the blower unit 10 and the target air heat exchanger unit 20 is improved.
The blower unit 10 is disposed upstream of the target air heat exchanger unit 20 in the flow direction of the wind generated by the sirocco fan 11 in the air path 40.
　送風機ユニット１０と対象空気熱交換器ユニット２０との間隔は、送風機ユニット１０および対象空気熱交換器ユニット２０のそれぞれにおけるユニット筐体１３、２３の風の流れ方向に対応した横幅よりも短い。すなわち、送風機ユニット１０と対象空気熱交換器ユニット２０との風の流れ方向に対応した間隔は、７０ｍｍ以上１００ｍｍ以下である。また、送風機ユニット１０および対象空気熱交換器ユニット２０のそれぞれにおけるユニット筐体１３、２３の風の流れ方向に対応した横幅は、５５０ｍｍ以下である。 The space | interval of the air blower unit 10 and the object air heat exchanger unit 20 is shorter than the horizontal width corresponding to the flow direction of the wind of the unit cases 13 and 23 in each of the air blower unit 10 and the object air heat exchanger unit 20. That is, the space | interval corresponding to the flow direction of the wind of the air blower unit 10 and the object air heat exchanger unit 20 is 70 mm or more and 100 mm or less. Moreover, the horizontal width | variety corresponding to the flow direction of the wind of the unit housing | casing 13 and 23 in each of the air blower unit 10 and the object air heat exchanger unit 20 is 550 mm or less.
　図４は、本発明の実施の形態１に係る送風機ユニット１０の構成の一例を示す概略図である。
　送風機ユニット１０は、直方体形状の箱型のユニット筐体１３を有している。
　送風機ユニット１０は、ダクト５４に接続される風路４０の風の流れ方向で上流側の接続箇所に、ユニット筐体１３から突出して内部が孔となったフランジ部１４を有している。送風機ユニット１０は、ダクト部材１に接続される風路４０の風の流れ方向で下流側の接続箇所に、ユニット筐体１３から突出して内部が孔となったフランジ部１５を有している。
　これらのフランジ部１４、１５は、送風機ユニット１０におけるユニット筐体１３の側面から円筒状に突出している。このため、フランジ部１４、１５およびフランジ部１４、１５に接続されるダクト５４あるいはダクト部材１のそれぞれの外周で囲われた面積は、送風機ユニット１０におけるユニット筐体１３のフランジ部１４、１５が突出した側面の面積に対して小さい。
　これらのフランジ部１４、１５の中心は、送風機ユニット１０におけるユニット筐体１３のフランジ部１４、１５が突出した側面の中心に対して、上方向に位置がずれるように配置されている。これにより、上側に位置した送風口１１ａからの風向きを横方向に向けられたシロッコファン１１からの送風が効率的になるようにしている。 FIG. 4 is a schematic diagram illustrating an example of the configuration of the blower unit 10 according to Embodiment 1 of the present invention.
The blower unit 10 has a rectangular parallelepiped box-shaped unit housing 13.
The blower unit 10 has a flange portion 14 that protrudes from the unit housing 13 and has a hole in the upstream connection portion in the air flow direction of the air passage 40 connected to the duct 54. The blower unit 10 has a flange portion 15 that protrudes from the unit housing 13 and has a hole in the downstream connection portion in the wind flow direction of the air passage 40 connected to the duct member 1.
These flange portions 14 and 15 protrude in a cylindrical shape from the side surface of the unit housing 13 in the blower unit 10. For this reason, the flange parts 14 and 15 and the flange 54 and 15 of the unit housing | casing 13 in the air blower unit 10 are the area enclosed by the outer periphery of the duct 54 connected to the flange parts 14 and 15, or the duct member 1, respectively. Small relative to the protruding side area.
The center of these flange parts 14 and 15 is arrange | positioned so that a position may shift | deviate upward with respect to the center of the side surface from which the flange parts 14 and 15 of the unit housing | casing 13 in the air blower unit 10 protruded. Thereby, the air from the sirocco fan 11 in which the wind direction from the air blowing port 11a located on the upper side is directed in the horizontal direction is made efficient.
　図４に示すように、送風機ユニット１０は、送風機としてシロッコファン１１を有している。シロッコファン１１は、風路４０の風の流れ方向で下流側を向いた送風口１１ａが、送風機ユニット１０のユニット筐体１３の上側に位置している。シロッコファン１１は、送風口１１ａからの風向きが横方向となるように配置されている。シロッコファン１１は、ユニット筐体１３の内部に収容されても、送風機ユニット１０が対象空気熱交換器ユニット２０よりも風路４０の風の流れ方向で上流側に配置されている。このため、シロッコファン１１には、対象空気熱交換器２１で発生する結露水の影響が及ばず、対象空気熱交換器２１で発生する結露水に対する防水対策が不要となる。 As shown in FIG. 4, the blower unit 10 has a sirocco fan 11 as a blower. In the sirocco fan 11, the air blowing port 11 a facing the downstream side in the wind flow direction of the air passage 40 is located above the unit housing 13 of the blower unit 10. The sirocco fan 11 is arranged so that the wind direction from the air outlet 11a is in the horizontal direction. Even if the sirocco fan 11 is housed inside the unit housing 13, the blower unit 10 is disposed upstream of the target air heat exchanger unit 20 in the air flow direction of the air passage 40. For this reason, the sirocco fan 11 is not affected by the condensed water generated in the target air heat exchanger 21, and a waterproof measure against the condensed water generated in the target air heat exchanger 21 becomes unnecessary.
　また、送風機ユニット１０は、ユニット筐体１３の内部に制御器１２を有している。制御器１２は、熱源側ユニット１００の制御器１１０と通信し、シロッコファン１１のモータの回転数を制御する。制御器１２は、ユニット筐体１３の内部に収容されても、送風機ユニット１０が対象空気熱交換器ユニット２０よりも風路４０の風の流れ方向で上流側に配置されている。このため、制御器１２には、対象空気熱交換器２１で発生する結露水の影響が及ばず、対象空気熱交換器２１で発生する結露水に対する防水対策が不要となる。 Moreover, the blower unit 10 has a controller 12 inside the unit housing 13. The controller 12 communicates with the controller 110 of the heat source side unit 100 and controls the rotation speed of the motor of the sirocco fan 11. Even if the controller 12 is housed inside the unit housing 13, the blower unit 10 is disposed upstream of the target air heat exchanger unit 20 in the wind flow direction of the air passage 40. For this reason, the controller 12 is not affected by the condensed water generated in the target air heat exchanger 21, and a waterproof measure against the condensed water generated in the target air heat exchanger 21 is not required.
　図５は、本発明の実施の形態１に係る対象空気熱交換器ユニット２０の構成の一例を示す概略図である。
　対象空気熱交換器ユニット２０は、直方体形状の箱型のユニット筐体２３を有している。
　対象空気熱交換器ユニット２０は、ダクト部材１に接続される風路４０の風の流れ方向で上流側の接続箇所に、ユニット筐体２３から突出して内部が孔となったフランジ部２４を有している。対象空気熱交換器ユニット２０は、ダクト５６に接続される風路４０の風の流れ方向で下流側の接続箇所に、ユニット筐体２３から突出して内部が孔となったフランジ部２５を有している。
　これらのフランジ部２４、２５は、対象空気熱交換器ユニット２０におけるユニット筐体２３の側面から円筒状に突出している。このため、フランジ部２４、２５およびフランジ部２４、２５に接続されるダクト部材１あるいはダクト５６のそれぞれの外周で囲われた面積は、対象空気熱交換器ユニット２０におけるユニット筐体２３のフランジ部２４、２５が突出した側面の面積に対して小さい。
　これらのフランジ部２４、２５の中心は、対象空気熱交換器ユニット２０におけるユニット筐体２３のフランジ部２４、２５が突出した側面の中心に対して、上方向に位置をずらして配置されている。これにより、シロッコファン１１からの送風が効率的に対象空気熱交換器ユニット２０に導入できるようにしている。 FIG. 5 is a schematic diagram showing an example of the configuration of the target air heat exchanger unit 20 according to Embodiment 1 of the present invention.
The target air heat exchanger unit 20 has a rectangular parallelepiped box-shaped unit housing 23.
The target air heat exchanger unit 20 has a flange portion 24 that protrudes from the unit housing 23 and has a hole in the upstream connection portion in the wind flow direction of the air passage 40 connected to the duct member 1. is doing. The target air heat exchanger unit 20 has a flange portion 25 that protrudes from the unit housing 23 and has a hole inside at a connection location on the downstream side in the wind flow direction of the air passage 40 connected to the duct 56. ing.
These flange portions 24 and 25 protrude in a cylindrical shape from the side surface of the unit housing 23 in the target air heat exchanger unit 20. For this reason, the area surrounded by the outer periphery of each of the duct members 1 or 56 connected to the flange portions 24 and 25 and the flange portions 24 and 25 is the flange portion of the unit housing 23 in the target air heat exchanger unit 20. 24 and 25 are small with respect to the area of the side surface which protruded.
The centers of the flange portions 24 and 25 are arranged so as to be shifted in the upward direction with respect to the center of the side surface of the unit housing 23 from which the flange portions 24 and 25 protrude in the target air heat exchanger unit 20. . Thereby, the ventilation from the sirocco fan 11 can be efficiently introduced into the target air heat exchanger unit 20.
　ここで、図３に示すように、送風機ユニット１０のフランジ部１５と対象空気熱交換器ユニット２０のフランジ部２４とを接続するダクト部材１の中心は、送風機ユニット１０および対象空気熱交換器ユニット２０のそれぞれにおけるユニット筐体１３、２３のフランジ部１５、２４が突出した側面の中心に対して、上方向に位置がずれて繋がっている。このため、ダクト部材１は、ダクト部材１の下方の障害物を回避することができる。 Here, as shown in FIG. 3, the center of the duct member 1 that connects the flange portion 15 of the blower unit 10 and the flange portion 24 of the target air heat exchanger unit 20 is the blower unit 10 and the target air heat exchanger unit. The unit housings 13 and 23 of the unit housings 13 and 23 are connected to the center of the side surface from which the flange portions 15 and 24 protrude in the upward direction. For this reason, the duct member 1 can avoid an obstacle below the duct member 1.
　図５に示すように、対象空気熱交換器ユニット２０は、ユニット筐体２３の内部の底部に、対象空気熱交換器２１で発生する結露水を受け止める皿状のドレンパン２６を有している。ドレンパン２６は、ユニット筐体２３の内部で対象空気熱交換器２１の配置される領域を下方に投影した投影領域よりも大きく設けられている。 As shown in FIG. 5, the target air heat exchanger unit 20 has a dish-shaped drain pan 26 that receives dew condensation water generated in the target air heat exchanger 21 at the bottom inside the unit housing 23. The drain pan 26 is provided larger than the projection area in which the area where the target air heat exchanger 21 is arranged is projected downward in the unit housing 23.
　対象空気熱交換器ユニット２０は、ユニット筐体２３の内部で対象空気熱交換器２１を対象空気が横方向に流れる風の流れ方向に対して傾斜して設置している。
　すなわち、対象空気熱交換器２１は、対象空気熱交換器ユニット２０のユニット筐体２３の内部で上部が下部よりも風路４０の風の流れ方向で上流側に位置するように傾斜して設置されている。 The target air heat exchanger unit 20 is installed inside the unit housing 23 with the target air heat exchanger 21 inclined with respect to the flow direction of the wind in which the target air flows in the lateral direction.
That is, the target air heat exchanger 21 is installed so as to be inclined so that the upper part is located upstream of the lower part in the air flow direction of the air passage 40 inside the unit housing 23 of the target air heat exchanger unit 20. Has been.
　なお、ダクト部材１は、送風機ユニット１０および対象空気熱交換器ユニット２０のそれぞれにおけるユニット筐体１３、２３のフランジ部１５、２４に接続できるものであればよい。ダクト部材１は、送風機ユニット１０あるいは対象空気熱交換器ユニット２０と一体的に形成されたものに適用することができる。
　ここで、送風機ユニット１０と対象空気熱交換器ユニット２０とが、ダクト部材１で着脱することができる場合には、送風機ユニット１０および対象空気熱交換器ユニット２０の設置の自由度および設置時の作業性が向上される。たとえば、フランジ部１５、２４の外周面または内周面にネジ加工が施されており、送風機ユニット１０および対象空気熱交換器ユニット２０とダクト部材１とは、ネジ構造によって接続される。 In addition, the duct member 1 should just be connected to the flange parts 15 and 24 of the unit housing | casing 13 and 23 in each of the air blower unit 10 and the object air heat exchanger unit 20. FIG. The duct member 1 can be applied to one formed integrally with the blower unit 10 or the target air heat exchanger unit 20.
Here, when the blower unit 10 and the target air heat exchanger unit 20 can be attached and detached with the duct member 1, the degree of freedom of installation of the blower unit 10 and the target air heat exchanger unit 20 and the installation time are as follows. Workability is improved. For example, the outer peripheral surface or inner peripheral surface of the flange portions 15 and 24 is threaded, and the blower unit 10 and the target air heat exchanger unit 20 and the duct member 1 are connected by a screw structure.
　図６は、本発明の実施の形態１に係る室内機の能力コードを示す図である。
　図６に示すように、室外機を構成する熱源側ユニット１００の制御器１１０は、送風機ユニット１０と対象空気熱交換器ユニット２０とを組み合わせた室内機の種類によって、室内機の能力コードを判定する。 FIG. 6 is a diagram showing the capacity code of the indoor unit according to Embodiment 1 of the present invention.
As shown in FIG. 6, the controller 110 of the heat source side unit 100 configuring the outdoor unit determines the capacity code of the indoor unit according to the type of the indoor unit that combines the blower unit 10 and the target air heat exchanger unit 20. To do.
　たとえば、空気調和装置３０を設置する作業者が、熱源側ユニット１００の制御器１１０に、室内機に関するデータを入力する。熱源側ユニット１００の制御器１１０は、入力されたデータから室内機の能力コードを判定する。なお、熱源側ユニット１００の制御器１１０は、室内機の能力コードを自動で判定する機能を有していてもよい。
　熱源側ユニット１００の制御器１１０は、室内機の能力コードに応じた運転を実行する。 For example, an operator who installs the air conditioner 30 inputs data related to the indoor unit to the controller 110 of the heat source side unit 100. The controller 110 of the heat source side unit 100 determines the capacity code of the indoor unit from the input data. Note that the controller 110 of the heat source side unit 100 may have a function of automatically determining the capacity code of the indoor unit.
The controller 110 of the heat source side unit 100 performs an operation according to the capacity code of the indoor unit.
　次に、図６を用いて能力コード３の送風機ユニット１０と対象空気熱交換器ユニット２０とを組み合わせた室内機の一例について説明する。
　能力コード３では、中風量の送風機ユニット１０と中容量の対象空気熱交換器ユニット２０とを組み合わせることができる。 Next, an example of an indoor unit in which the blower unit 10 with the capacity code 3 and the target air heat exchanger unit 20 are combined will be described with reference to FIG.
In the capacity code 3, the medium air volume blower unit 10 and the medium capacity target air heat exchanger unit 20 can be combined.
　また、能力コード３では、小風量の送風機ユニット１０と大容量の対象空気熱交換器ユニット２０とを組み合わせることもできる。小風量と大容量との組み合せとすることで、ドラフト感のないマイルド空調あるいは低騒音での運転を提供することができる。
　なお、たとえば、ガラス張り建築などの空調負荷の高い部屋では、空調能力を格上げ使用した際に、風量が大き過ぎてドラフト感を感じたり、騒音が大きくしたりするなど、十分な満足が得られていない可能性がある。 In the capacity code 3, the blower unit 10 having a small air volume and the target air heat exchanger unit 20 having a large capacity can be combined. By combining a small air volume and a large capacity, it is possible to provide mild air conditioning without a draft feeling or operation with low noise.
For example, in a room with a high air conditioning load such as a glass-walled building, when the air conditioning capacity is upgraded and used, the air volume is too large and the draft feeling is felt or the noise is increased. There is no possibility.
　また、能力コード３では、大風量の送風機ユニット１０と小容量の対象空気熱交換器ユニット２０とを組み合わせることもできる。大風量と小容量との組み合せとすることで、多数の部屋にダクト分岐され大風量が必要な場合、あるいは、低湿度地域で冷房時の除湿を抑えたい高顕熱要求の場合などの空気調和装置３０を提供することができる。 In the capacity code 3, the large air volume blower unit 10 and the small capacity target air heat exchanger unit 20 can be combined. A combination of a large air volume and a small capacity allows air conditioning equipment to be used when a large number of air is needed due to the branching of ducts in a large number of rooms, or when high sensible heat is required to reduce dehumidification during cooling in low humidity areas. 30 can be provided.
　能力コード３のいずれの組み合せにおいても冷房能力および暖房能力は同等である。室外機と室内機とのシステム通信あるいは冷媒制御を行うために、室内機側の送風機ユニット１０と対象空気熱交換器ユニット２０との組み合せを認識する必要がある。図６に示す組み合せによる能力コードが付与され、施工時に初期設定する。
　たとえば、能力コード３となる機種選定をする際には、同一能力でも、設置シーンに見合った風量を選定することができる。そして、異なる容量から対象空気熱交換器サイズあるいは対象空気熱交換器ユニット２０のユニットサイズの選択ができる。逆に言えば、送風機ユニット１０と対象空気熱交換器ユニット２０との組み合せで、小刻みな能力コードを得ることができる。 In any combination of the capability codes 3, the cooling capability and the heating capability are the same. In order to perform system communication or refrigerant control between the outdoor unit and the indoor unit, it is necessary to recognize the combination of the blower unit 10 on the indoor unit side and the target air heat exchanger unit 20. The ability code by the combination shown in FIG. 6 is given and is initially set at the time of construction.
For example, when selecting a model with the capability code 3, it is possible to select an air volume suitable for the installation scene even with the same capability. And the target air heat exchanger size or the unit size of the target air heat exchanger unit 20 can be selected from different capacities. In other words, a small capacity code can be obtained by combining the blower unit 10 and the target air heat exchanger unit 20.
　ここで、ダクト式空調では、多様な機外静圧に対応した送風機が必要となる。高機外静圧が必要となる場合は、一般的にファン径が大きくなる。ファン径の異なる送風機ユニット１０を選択することにより、機外静圧ゼロの直吹きから高機外静圧の用途に対応することができる。
　また、風路４０の途中に送風機ユニット１０を複数設置することにより、ブースターファンとして更に機外静圧を引き上げることもできる。 Here, in the duct type air conditioning, a blower corresponding to various external static pressures is required. When high static pressure outside the machine is required, the fan diameter is generally increased. By selecting the blower unit 10 having a different fan diameter, it is possible to cope with a high external static pressure application from a direct blow with no external static pressure.
Further, by installing a plurality of blower units 10 in the middle of the air passage 40, the external static pressure can be further increased as a booster fan.
　以上の実施の形態１によれば、空気調和装置３０は、圧縮機１０２、熱源側熱交換器１０６、絞り装置２２および対象空気熱交換器２１を冷媒配管１２０で配管接続して構成される冷凍サイクル回路を備えている。空気調和装置３０は、シロッコファン１１を収容した送風機ユニット１０を有している。空気調和装置３０は、対象空気熱交換器２１を収容した対象空気熱交換器ユニット２０を有している。送風機ユニット１０は、対象空気熱交換器ユニット２０よりもシロッコファン１１の生成する風の流れ方向で上流側に配置されている。
　この構成によれば、送風機ユニット１０が対象空気熱交換器ユニット２０よりもシロッコファン１１の生成する風の流れ方向で上流側に配置されている。このため、風路４０では、対象空気がシロッコファン１１から対象空気熱交換器２１に流れる押込み型の構成となる。したがって、対象空気熱交換器ユニット２０に収容された対象空気熱交換器２１で生じた結露水が、対象空気熱交換器ユニット２０よりも風路４０の風の流れ方向で上流側に配置される送風機ユニット１０に収容されたシロッコファン１１に付着することを防止した。また、送風機ユニット１０が対象空気熱交換器ユニット２０とは別体であるため、対象空気熱交換器ユニット２０に収容された対象空気熱交換器２１で生じた結露水が、送風機ユニット１０に収容されたシロッコファン１１に付着することを防止する効果が顕著となる。
　さらに、従来技術とは異なり、空調空気が送風機ユニット１０を通らない構成である。このため、送風機ユニット１０のシロッコファン１１への熱負荷の影響が低減される。
　さらに、シロッコファン１１と対象空気熱交換器２１との間の距離を大きくとることができる。このため、空気調和装置３０の静音性が向上できる。
　また、送風機ユニット１０と対象空気熱交換器ユニット２０とを別ユニットにすることによって、多様な市場ニーズにマッチした機種選定ができる。すなわち、多様な設置環境またはニーズに合わせて、製品サイズ、風量、騒音、機外静圧などをカスタマイズした空気調和装置３０が提供できる。
　なお、従来では、単に必要とする能力のみで室内機の選定を行っていた。このため、サイズ、風量、騒音、機外静圧などが、設置環境およびニーズに合わせられた空気調和装置を得ることは困難であった。
　たとえば、従来の一体型ユニットでは、三角屋根の戸建て住宅において、高さ、幅、奥行きといった製品サイズが大きく天井梁に干渉してしまう場合があった。しかし、実施の形態１によれば、送風機ユニット１０と対象空気熱交換器ユニット２０とが分離した分離設置構造によって梁の位置にダクト部材１あるいは２つのダクト５４、５６のいずれかを配置し、梁をかわすことができる。
　さらに、実施の形態１によれば、送風機ユニット１０と対象空気熱交換器ユニット２０との組み合せ選定によって、それぞれのユニットの更なるサイズ調整が行え、選択肢が広がる。
　また、実施の形態１によれば、低コストのＡＣモータ送風機を備えた送風機ユニット１０と節電能力の高いＤＣモータ送風機を備えた送風機ユニット１０とのいずれかをユーザが選択することができる。 According to the first embodiment described above, the air conditioner 30 is a refrigeration constructed by connecting the compressor 102, the heat source side heat exchanger 106, the expansion device 22 and the target air heat exchanger 21 through the refrigerant pipe 120.

According to this configuration, the blower unit 10 is disposed upstream of the target air heat exchanger unit 20 in the flow direction of the wind generated by the sirocco fan 11. Therefore, the air passage 40 has a push-type configuration in which the target air flows from the sirocco fan 11 to the target air heat exchanger 21. Therefore, the dew condensation water generated in the target air heat exchanger 21 accommodated in the target air heat exchanger unit 20 is arranged upstream of the target air heat exchanger unit 20 in the wind flow direction of the air path 40. It was prevented from adhering to the sirocco fan 11 accommodated in the blower unit 10. Further, since the blower unit 10 is separate from the target air heat exchanger unit 20, the dew condensation water generated in the target air heat exchanger 21 accommodated in the target air heat exchanger unit 20 is accommodated in the blower unit 10. The effect of preventing adhesion to the sirocco fan 11 is remarkable.
Furthermore, unlike the prior art, the conditioned air does not pass through the blower unit 10. For this reason, the influence of the thermal load to the sirocco fan 11 of the blower unit 10 is reduced.
Furthermore, the distance between the sirocco fan 11 and the target air heat exchanger 21 can be increased. For this reason, the silence of the air conditioning apparatus 30 can be improved.
Further, by making the blower unit 10 and the target air heat exchanger unit 20 as separate units, it is possible to select models that match various market needs. That is, it is possible to provide the air conditioner 30 in which the product size, the air volume, the noise, the external static pressure, etc. are customized according to various installation environments or needs.
Conventionally, the indoor unit is selected only by the required capacity. For this reason, it has been difficult to obtain an air conditioner whose size, air volume, noise, external static pressure, etc. are matched to the installation environment and needs.
For example, in the conventional integrated unit, in a detached house with a triangular roof, the product size such as height, width, and depth may be large and interfere with the ceiling beam. However, according to the first embodiment, either the duct member 1 or the two ducts 54 and 56 are arranged at the beam position by the separated installation structure in which the blower unit 10 and the target air heat exchanger unit 20 are separated, You can dodge the beam.
Further, according to the first embodiment, by selecting a combination of the blower unit 10 and the target air heat exchanger unit 20, the size of each unit can be further adjusted, and options can be expanded.
Further, according to the first embodiment, the user can select either the blower unit 10 provided with a low-cost AC motor blower or the blower unit 10 provided with a DC motor blower having a high power saving capability.
