Description

空気調和装置の室外機Air conditioner outdoor unit
　本発明は、加湿ユニットを有する空気調和装置の室外機に関する。 The present invention relates to an outdoor unit of an air conditioner having a humidifying unit.
　加湿機能を有する従来の空気調和装置の中には、空気調和装置の室外機と加湿ユニットとが一体化されたタイプのものがある。例えば、特許文献１（特開２００８－２４１２１２号公報）に開示されている空気調和装置では、室外機が上下仕切板によって上下に仕切られており、加湿ユニットは上下仕切板の上方に設置され、熱交換器や熱交換器に送風するファンは上下仕切板の下方に配置されている。 Among conventional air conditioners having a humidifying function, there is a type in which an outdoor unit of an air conditioner and a humidifying unit are integrated. For example, in the air conditioner disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 2008-241212), the outdoor unit is partitioned up and down by upper and lower partition plates, and the humidification unit is installed above the upper and lower partition plates, A heat exchanger and a fan that blows air to the heat exchanger are disposed below the upper and lower partition plates.
　このような加湿機能を有する室外機は、加湿機能を有しないタイプに比べて大型化するので、その大型化を抑制する必要がある。そのため、加湿ユニットを室外機内で室外熱交換器の空気流れの下流側に配置することも検討されている。
　しかしながら、その場合、加湿に利用する外気を取り入れる際に、室外熱交換器を通過した空気を取り入れる可能性が高い。特に、暖房運転時は、室外熱交換器が蒸発器として機能しており、そこを通過する空気は冷却されているので、低温の空気が加湿ユニット内に取り入れられることになる。その結果、例えば、ヒータへの電力供給が室外熱交換器を通過しない空気を取り込む場合と比較して増加し、消費電力の増加や、水分吸着量の減少による加湿能力の減少などの問題が生じる可能性が高い。
　本発明の課題は、加湿ユニットが内蔵されている、空気調和装置の室外機において、室外熱交換器を通過した空気を加湿ユニットに取り入れさせない室外機を提供することにある。 An outdoor unit having such a humidifying function is increased in size as compared with a type that does not have a humidifying function. Therefore, it is necessary to suppress the increase in size. For this reason, it has been studied to arrange the humidification unit in the outdoor unit on the downstream side of the air flow of the outdoor heat exchanger.
However, in that case, when taking in the outside air used for humidification, there is a high possibility of taking in air that has passed through the outdoor heat exchanger. In particular, during the heating operation, the outdoor heat exchanger functions as an evaporator, and the air passing therethrough is cooled, so that low-temperature air is taken into the humidification unit. As a result, for example, the power supply to the heater increases as compared with the case of taking in air that does not pass through the outdoor heat exchanger, and problems such as an increase in power consumption and a decrease in humidification capacity due to a decrease in the amount of moisture adsorption occur. Probability is high.
The subject of this invention is providing the outdoor unit which does not let the humidification unit take in the air which passed the outdoor heat exchanger in the outdoor unit of the air conditioning apparatus with which the humidification unit is incorporated.
　本発明の第１観点に係る空気調和装置の室外機は、本体ケーシングと、室外熱交換器と、加湿ユニットとを備えている。本体ケーシングは、空気吸込開口と空気吹出開口とを有する。室外熱交換器は、本体ケーシング内で空気吸込開口と対向するように配置される。加湿ユニットは、本体ケーシング内で室外熱交換器の空気流れの下流側に配置される。また、加湿ユニットは、水分吸着素子と、ヒータと、外気取り入れ口とを有している。水分吸着素子は、水分を吸着し、加熱されることによって水分を放出する。ヒータは、水分吸着素子および／または水分吸着素子に向う空気を加熱する。外気取り入れ口は、水分吸着素子に向かう空気を外部から導入する。さらに、外気取り入れ口は、室外熱交換器を通過した空気が流れる流路から外れた空間に設けられている。
　この空気調和装置の室外機では、外気取り入れ口が室外熱交換器を通過した空気が流れる流路から外れることによって、当該空気を取り入れる可能性がほぼ排除される。その結果、取り入れ空気の温度低下によるヒータ消費電力の増加を防止することができる。 The outdoor unit of the air conditioning apparatus which concerns on the 1st viewpoint of this invention is equipped with the main body casing, the outdoor heat exchanger, and the humidification unit. The main body casing has an air suction opening and an air outlet opening. An outdoor heat exchanger is arrange | positioned so that an air suction opening may be opposed in a main body casing. A humidification unit is arrange | positioned in the main body casing at the downstream of the air flow of an outdoor heat exchanger. Moreover, the humidification unit has a moisture adsorption element, a heater, and an outside air intake. The moisture adsorption element adsorbs moisture and releases moisture by being heated. The heater heats the moisture adsorption element and / or air toward the moisture adsorption element. The outside air intake port introduces air from the outside toward the moisture adsorption element. Furthermore, the outside air intake is provided in a space that is out of the flow path through which the air that has passed through the outdoor heat exchanger flows.
In the outdoor unit of this air conditioner, the possibility of taking in the air is almost eliminated by removing the outside air intake from the flow path through which the air that has passed through the outdoor heat exchanger flows. As a result, an increase in heater power consumption due to a decrease in the temperature of intake air can be prevented.
　本発明の第２観点に係る空気調和装置の室外機は、第１観点に係る空気調和装置の室外機であって、室外熱交換器を通過した空気が、空気吹出開口から吹き出される。そして、外気取り入れ口は、空気吹出開口と同じ方向に開口している。
　この空気調和装置の室外機では、少なくとも外気取り入れ口が、空気吹出開口に向って開口していないので、空気吹出開口からの空気を取り入れる可能性がほぼ排除される。 The outdoor unit of the air conditioning apparatus which concerns on the 2nd viewpoint of this invention is an outdoor unit of the air conditioning apparatus which concerns on a 1st viewpoint, Comprising: The air which passed the outdoor heat exchanger blows off from an air blowing opening. The outside air intake port opens in the same direction as the air blowing opening.
In the outdoor unit of this air conditioner, at least the outside air intake port does not open toward the air blowing opening, so the possibility of taking in air from the air blowing opening is almost eliminated.
　本発明の第３観点に係る空気調和装置の室外機は、第２観点に係る空気調和装置の室外機であって、ベルマウスをさらに備えている。ベルマウスは、室外熱交換器を通過した空気を空気吹出開口へ案内する。また、外気取り入れ口は、ベルマウスの周縁より外側に位置する。
　この空気調和装置の室外機では、外気取り入れ口がベルマウスの周縁より外側に位置するので、ベルマウスを通過した空気を取り入れる可能性がほぼ排除される。 The outdoor unit of the air conditioning apparatus which concerns on the 3rd viewpoint of this invention is an outdoor unit of the air conditioning apparatus which concerns on a 2nd viewpoint, Comprising: The bell mouth is further provided. The bell mouth guides the air that has passed through the outdoor heat exchanger to the air blowing opening. The outside air intake is located outside the peripheral edge of the bell mouth.
In the outdoor unit of this air conditioner, since the outside air intake is located outside the peripheral edge of the bell mouth, the possibility of taking in air that has passed through the bell mouth is almost eliminated.
　本発明の第４観点に係る空気調和装置の室外機は、第１観点に係る空気調和装置の室外機であって、防護グリルと、遮蔽板とをさらに備えている。防護グリルは、本体ケーシングのうち空気吹出開口が形成されている前板に取り付けられ、空気吹出開口を覆う。遮蔽板は、防護グリルと前板との間に配置され、空気吹出開口から吹き出される空気が通る吹き出し流路と外気取り入れ口とを仕切る。
　この空気調和装置の室外機では、空気吹出開口から吹き出される空気のうち、防護グリルと前板との間を通って外気取り入れ口に進入しようとする空気を遮蔽板が阻止する。 The outdoor unit of the air conditioning apparatus which concerns on the 4th viewpoint of this invention is an outdoor unit of the air conditioning apparatus which concerns on a 1st viewpoint, Comprising: The protection grille and the shielding board are further provided. The protective grille is attached to a front plate in which an air blowing opening is formed in the main body casing, and covers the air blowing opening. The shielding plate is disposed between the protective grille and the front plate, and partitions the blowing flow path through which the air blown from the air blowing opening passes and the outside air intake.
In the outdoor unit of this air conditioner, the shielding plate blocks air that is about to enter the outside air intake port between the protective grille and the front plate among the air blown from the air blowing opening.
　本発明の第５観点に係る空気調和装置の室外機は、第１観点に係る空気調和装置の室外機であって、加湿ユニットが第２外気取り入れ口をさらに有している。第２外気取り入れ口は、水分を水分吸着素子に吸着させるために使用する外気を取り入れる。また、第２外気取り入れ口が、室外熱交換器を通過した空気が流れる流路から外れた空間に設けられている。 The outdoor unit of the air conditioner according to the fifth aspect of the present invention is the outdoor unit of the air conditioner according to the first aspect, and the humidifying unit further includes a second outside air intake. The second outside air intake takes in outside air used for adsorbing moisture to the moisture adsorption element. Moreover, the 2nd external air intake is provided in the space remove | deviated from the flow path through which the air which passed the outdoor heat exchanger flows.
　暖房運転時、室外熱交換器は蒸発器として機能しており、室外熱交換器を通過する空気中の水分が室外熱交換器と接触して凝縮するので、水分量が減少した空気が加湿ユニット内に取り入れられることになる。その結果、室外熱交換器を通過しない空気を取り込む場合と比較して、水分量が減少した分だけ加湿性能が低下する。しかし、この空気調和装置の室外機では、第２外気取り入れ口が室外熱交換器を通過した空気が流れる流路から外れることによって、当該空気を取り入れる可能性がほぼ排除される。その結果、取り入れ空気の水分量低下による加湿性能の低下を防止することができる。 During heating operation, the outdoor heat exchanger functions as an evaporator, and moisture in the air that passes through the outdoor heat exchanger comes into contact with the outdoor heat exchanger and condenses. It will be incorporated in. As a result, compared with the case where the air which does not pass an outdoor heat exchanger is taken in, humidification performance falls by the part which the water | moisture content reduced. However, in the outdoor unit of the air conditioner, the possibility that the second outdoor air intake port is removed from the flow path through which the air that has passed through the outdoor heat exchanger flows is almost eliminated. As a result, it is possible to prevent a decrease in humidification performance due to a decrease in the moisture content of the intake air.
　本発明の第１観点に係る空気調和装置の室外機では、外気取り入れ口が室外熱交換器を通過した空気が流れる流路から外れることによって、当該空気を取り入れる可能性がほぼ排除される。その結果、取り入れ空気の温度低下によるヒータ消費電力の増加を防止することができる。
　本発明の第２観点に係る空気調和装置の室外機では、少なくとも外気取り入れ口が、空気吹出開口に向って開口していないので、空気吹出開口からの空気を取り入れる可能性がほぼ排除される。
　本発明の第３観点に係る空気調和装置の室外機では、外気取り入れ口がベルマウスの周縁より外側に位置するので、ベルマウスを通過した空気を取り入れる可能性がほぼ排除される。 In the outdoor unit of the air conditioner according to the first aspect of the present invention, the possibility that the outside air intake is removed from the flow path through which the air that has passed through the outdoor heat exchanger flows is almost eliminated. As a result, an increase in heater power consumption due to a decrease in the temperature of intake air can be prevented.
In the outdoor unit of the air conditioner according to the second aspect of the present invention, at least the outside air intake port does not open toward the air blowing opening, so the possibility of taking in air from the air blowing opening is almost eliminated.
In the outdoor unit of the air conditioner according to the third aspect of the present invention, since the outside air intake is located outside the peripheral edge of the bell mouth, the possibility of taking in air that has passed through the bell mouth is almost eliminated.
　本発明の第４観点に係る空気調和装置の室外機では、空気吹出開口から吹き出される空気のうち、防護グリルと前板との間を通って外気取り入れ口に進入しようとする空気を遮蔽板が阻止する。
　本発明の第５観点に係る空気調和装置の室外機では、第２外気取り入れ口が室外熱交換器を通過した空気が流れる流路から外れることによって、当該空気を取り入れる可能性がほぼ排除される。その結果、取り入れ空気の水分量低下による加湿性能の低下を防止することができる。 In the outdoor unit of the air conditioner according to the fourth aspect of the present invention, the air that is about to enter the outside air intake through the space between the protective grille and the front plate among the air blown from the air blowing opening is shielded. Will stop.

　以下、図面を参照しながら、本発明の実施形態について説明する。なお、以下の実施形態は、本発明の具体例であって、本発明の技術的範囲を限定するものではない。
　（１）空気調和装置の構成の概要
　図１は、本発明の一実施形態に係る室外機３０を備えた空気調和装置１０の構成図である。図１において、室内機２０と室外機３０とは冷媒配管１４，１６によって接続されている。空気調和装置１０は、冷房運転、暖房運転、除湿運転、加湿運転、及び給気運転などの複数の運転モードを持っており、これらの運転モードを適宜組み合わせることもできる。
　室内機２０には室内熱交換器２１が設けられ、室外機３０には圧縮機３１、四路切換弁３２、室外熱交換器３３、電動弁３４、アキュムレータ３６、液閉鎖弁３７及びガス閉鎖弁３８が設けられている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments are specific examples of the present invention and do not limit the technical scope of the present invention.
(1) Outline of Configuration of Air Conditioner FIG. 1 is a configuration diagram of an air conditioner 10 including an outdoor unit 30 according to an embodiment of the present invention. In FIG. 1, the indoor unit 20 and the outdoor unit 30 are connected by refrigerant pipes 14 and 16. The air conditioner 10 has a plurality of operation modes such as a cooling operation, a heating operation, a dehumidifying operation, a humidifying operation, and an air supply operation, and these operation modes can be appropriately combined.
The indoor unit 20 includes an indoor heat exchanger 21, and the outdoor unit 30 includes a compressor 31, a four-way switching valve 32, an outdoor heat exchanger 33, an electric valve 34, an accumulator 36, a liquid closing valve 37, and a gas closing valve. 38 is provided.
　また、加湿運転、及び給気運転では、室内に外気を供給するため、給気ホース１８を通して室内機２０と室外機３０との間で空気の移動がある。特に、加湿運転では、水分を多く含んだ湿度の高い空気を室外機３０から室内機２０に供給するため室外機３０において外気から水分を取り込む。そのために、室外機３０には、外気から水分を取り込む機能を持つ加湿ユニット６０が設けられている。
　（１－１）冷媒の流れ
　次に、冷媒の流れについて、図１を参照しながら説明する。冷房時、四路切換弁３２内の流路は図１の実線で描かれた接続になっている。圧縮機３１で圧縮され吐出された冷媒は、四路切換弁３２を介して室外熱交換器３３に送られる。室外熱交換器３３において外気との熱交換によって熱を奪われた冷媒は、凝縮して高圧の液冷媒となって電動弁３４に送られる。 Further, in the humidifying operation and the air supply operation, air is moved between the indoor unit 20 and the outdoor unit 30 through the air supply hose 18 in order to supply outside air into the room. In particular, in the humidifying operation, in order to supply high humidity air containing a lot of moisture from the outdoor unit 30 to the indoor unit 20, the outdoor unit 30 takes in moisture from the outside air. For this purpose, the outdoor unit 30 is provided with a humidifying unit 60 having a function of taking moisture from the outside air.
(1-1) Refrigerant Flow Next, the refrigerant flow will be described with reference to FIG. During cooling, the flow path in the four-way switching valve 32 is connected as depicted by the solid line in FIG. The refrigerant compressed and discharged by the compressor 31 is sent to the outdoor heat exchanger 33 through the four-way switching valve 32. The refrigerant that has been deprived of heat by heat exchange with the outside air in the outdoor heat exchanger 33 is condensed and sent to the motor operated valve 34 as a high-pressure liquid refrigerant.
　高圧液冷媒は、電動弁３４を通過するときに絞られて圧力が低下し、膨張して温度が低下する。このとき、冷媒は低圧の湿り蒸気に変化する。低圧の冷媒は、液閉鎖弁３７及び液冷媒配管１４を通って室内熱交換器２１に入る。
　室内熱交換器２１では、冷媒は室内空気との熱交換によって蒸発しガス冷媒となる。ガス冷媒は、ガス冷媒配管１６を通り、ガス閉鎖弁３８を経由して四路切換弁３２に送られる。ガス冷媒の進路は、四路切換弁３２によって圧縮機３１の吸込方向に向けられ、アキュムレータ３６を経由して圧縮機３１に吸い込まれる。
　暖房時、四路切換弁３２内の流路は点線で描かれた接続になっている。圧縮機３１で圧縮され吐出された冷媒は、四路切換弁３２を介して室内熱交換器２１に送られる。そして、冷房時とは逆の経路をたどって、室外熱交換器３３を出た冷媒は圧縮機３１に戻ってくる。つまり、圧縮機３１、四路切換弁３２、ガス冷媒配管１６、室内熱交換器２１、液冷媒配管１４、電動弁３４、室外熱交換器３３、四路切換弁３２、アキュムレータ３６及び圧縮機３１の順に冷媒が循環する。 The high-pressure liquid refrigerant is squeezed when it passes through the motor-operated valve 34, the pressure is reduced, and the temperature is lowered by expansion. At this time, the refrigerant changes to low-pressure wet steam. The low-pressure refrigerant enters the indoor heat exchanger 21 through the liquid closing valve 37 and the liquid refrigerant pipe 14.
In the indoor heat exchanger 21, the refrigerant evaporates by heat exchange with room air and becomes a gas refrigerant. The gas refrigerant passes through the gas refrigerant pipe 16 and is sent to the four-way switching valve 32 via the gas closing valve 38. The course of the gas refrigerant is directed in the suction direction of the compressor 31 by the four-way switching valve 32 and sucked into the compressor 31 via the accumulator 36.
During heating, the flow path in the four-way selector valve 32 is connected with a dotted line. The refrigerant compressed and discharged by the compressor 31 is sent to the indoor heat exchanger 21 via the four-way switching valve 32. Then, the refrigerant exiting the outdoor heat exchanger 33 returns to the compressor 31 along a path opposite to that during cooling. That is, the compressor 31, the four-way switching valve 32, the gas refrigerant pipe 16, the indoor heat exchanger 21, the liquid refrigerant pipe 14, the electric valve 34, the outdoor heat exchanger 33, the four-way switching valve 32, the accumulator 36, and the compressor 31. The refrigerant circulates in this order.
　（２）室内機２０の構成
　室内機２０には、図１に示すようにモータで駆動される室内ファン２２が室内熱交換器２１の下流側に設けられている。室内ファン２２は、クロスフローファンである。室内ファン２２が駆動されると、室内機２０上部の吸込口２３から吸い込まれた室内空気は、室内熱交換器２１を通過して室内機２０下部の吹出口２４から吹き出される。
　また、室内機２０には、給気ホース１８の給気口２５が、室内熱交換器２１の上流側空間に設けられている。給気ホース１８は加湿ユニット６０に接続されており、加湿ユニット６０から送られてくる湿度の高い空気が給気口２５から室内熱交換器２１の上流側空間に供給される。このような湿度の高い空気が給気口２５から供給されている状態で室内ファン２２を駆動することにより、室内機２０の吹出口２４から吹き出される調和空気の湿度を高くすることができる。例えば、このとき同時に室内熱交換器２１を蒸発器として用いて、室内機２０に、加湿運転と冷房運転を同時に行わせることができる。 (2) Configuration of Indoor Unit 20 The indoor unit 20 is provided with an indoor fan 22 driven by a motor on the downstream side of the indoor heat exchanger 21 as shown in FIG. The indoor fan 22 is a cross flow fan. When the indoor fan 22 is driven, the indoor air sucked from the inlet 23 at the top of the indoor unit 20 passes through the indoor heat exchanger 21 and is blown out from the outlet 24 at the bottom of the indoor unit 20.
In the indoor unit 20, an air supply port 25 of the air supply hose 18 is provided in the upstream space of the indoor heat exchanger 21. The air supply hose 18 is connected to the humidification unit 60, and high-humidity air sent from the humidification unit 60 is supplied from the air supply port 25 to the upstream space of the indoor heat exchanger 21. By driving the indoor fan 22 in a state where such high-humidity air is supplied from the air supply port 25, the humidity of the conditioned air blown from the air outlet 24 of the indoor unit 20 can be increased. For example, at this time, the indoor heat exchanger 21 can be used as an evaporator at the same time to cause the indoor unit 20 to perform a humidifying operation and a cooling operation at the same time.
　（３）室外機３０の構成
　（３－１）全体構成

The outdoor unit 30 includes an outdoor fan 39 in addition to the outdoor heat exchanger 33 and the humidification unit 60. When the outdoor fan 39 is driven, outside air is sucked in from the rear side of the outdoor heat exchanger 33, passes through the outdoor heat exchanger 33, and is blown out from the outlet 46a (see FIG. 4). The front surface of the air outlet 46a is covered with a protective grill 56 so that the propeller 39b cannot be touched from the outside.

(3-2) Detailed configuration (3-2-1) Casing 40
The casing 40 is a casing including a front plate 46, a right side plate 47, a top plate 48 (see FIG. 2), a bottom plate 49, a back surface portion 50 (see FIG. 2), and a left side plate (not shown).

The width direction of the partition plate 43 extends in an arc shape from the right end of the outdoor heat exchanger 33 toward the front. As a result, the partition plate 43 has a function of shielding the wind from flowing from the blower chamber 41 to the machine chamber 42.
　また、図４に示すように、前板４６には、円形の吹出口４６ａが形成されている。吹出口４６ａには、その周縁に沿うようにリング状のベルマウス５２が取り付けられている。
　（３－２－２）圧縮機３１
　圧縮機３１は、機械室４２側に位置しており、底板４９に固定されている。運転時、圧縮機３１は高温になるので、機械室４２は送風機室４１に比較して温度が高くなっている。

(3-2-2) Compressor 31
The compressor 31 is located on the machine room 42 side and is fixed to the bottom plate 49. During operation, the compressor 31 is at a high temperature, so that the temperature in the machine room 42 is higher than that in the blower room 41.

　（３－２－６）防護グリル５６
　防護グリル５６は、ケーシング４０の前板４６に取り付けられ、吹出口４６ａを覆っている。防護グリル５６には、外気を吹き出すため、開口部５６ａが多数形成されている。 (3-2-4) Outdoor heat exchanger 33
The outdoor heat exchanger 33 is formed in an L shape so as to face the back surface portion of the casing 40 and the left side plate. Further, the height of the outdoor heat exchanger 33 has a dimension substantially equal to the distance between the top plate 48 and the bottom plate 49.
(3-2-5) Outdoor fan 39
The outdoor fan 39 has a propeller 39b driven by a fan motor 39a, and is provided on the downstream side of the outdoor heat exchanger 33. A part of the propeller 39b is arranged so as to enter a space surrounded by the bell mouth 52.
(3-2-6) Protective grill 56
The protective grill 56 is attached to the front plate 46 of the casing 40 and covers the air outlet 46a. A large number of openings 56a are formed in the protective grill 56 in order to blow out outside air.

FIG. 5 is a perspective view of the outdoor unit 30 with the front plate 46, the right side plate 47, and the electrical component unit 55 removed from the outdoor unit 30 of FIG. 4. In FIG. 5, the humidification unit 60 is disposed above the outdoor fan 39 between the outdoor heat exchanger 33 and the front plate 46. Moreover, the humidification unit 60 is arrange | positioned ranging over the air blower room 41 and the machine room 42, and the height of the upper surface corresponds with the height of the upper end of the outdoor heat exchanger 33. FIG. As shown in FIG. 1, the humidification unit 60 has an adsorption part 61 for adsorbing moisture from the outside air, and a release part 62 for releasing moisture taken in by the adsorption part 61.
(4) Detailed configuration of humidification unit 60 (4-1) Humidification rotor 63
The suction part 61 and the discharge part 62 are constituted by a single disc-shaped humidification rotor 63, and the part that was previously the suction part 61 by rotation becomes the discharge part 62, and the discharge part 62 is the first. The part becomes the adsorption part 61. The humidification rotor 63 is attached so as to rotate about the center of the disk as a rotation axis, and is transmitted to a gear 63a (see FIG. 6) provided around the humidification rotor 63 (see FIG. 6). It is rotated by the power of
　加湿ロータ６３は、ゼオライト等の焼成によって形成されたハニカム構造のゼオライトロータである。ゼオライト等の吸着剤は、常温で空気から水分を吸着し、ヒータなどの熱源で高温に加熱された空気に曝されて温度上昇したときに水分を放出する。つまり、加湿ロータ６３のうちの高温の空気にさらされていない側が吸着部６１になり、高温の空気にさらされている側が放出部６２になる。また、加湿ユニット６０は、加湿ロータ６３の放出部６２を通過させる空気を加熱するため、放出部６２の上方にヒータ７１（図１参照）を有している。なお、加湿ロータ６３の外周の全周囲は、包囲壁によって包囲されている。
　（４－２）吸着用ダクト６８
　図１において、吸着部６１には、吸着部６１に外気を導くための吸着用ダクト６８が設けられている。また、吸着用ダクト６８は、正面部前方に向かって開口していて外気を吸い込む吸着用吸入口２７２を形成している。 The humidification rotor 63 is a zeolite rotor having a honeycomb structure formed by firing of zeolite or the like. Adsorbents such as zeolite adsorb moisture from air at room temperature, and release moisture when exposed to air heated to a high temperature by a heat source such as a heater to raise the temperature. That is, the side of the humidifying rotor 63 that is not exposed to the high-temperature air becomes the adsorption part 61, and the side that is exposed to the high-temperature air becomes the discharge part 62. Further, the humidifying unit 60 has a heater 71 (see FIG. 1) above the discharge unit 62 in order to heat the air that passes through the discharge unit 62 of the humidification rotor 63. Note that the entire outer periphery of the humidification rotor 63 is surrounded by an enclosure wall.
(4-2) Adsorption duct 68
In FIG. 1, the suction part 61 is provided with a suction duct 68 for guiding outside air to the suction part 61. The suction duct 68 is open toward the front of the front portion and forms a suction inlet 272 for sucking outside air.
　水分を含む空気は、吸着用吸入口２７２から吸い込まれた後、吸着用ダクト６８内を流れて加湿ロータ６３に到達し、加湿ロータ６３を透過する際に水分が吸着され、排気口２７３から排出される。排気口２７３は、室外ファン３９が回転するときに負圧になる空間に対向しており、排気口２７３側の気圧が吸着用吸入口２７２側より低くなる原理によって、空気が吸着用吸入口２７２から吸い込まれる。
　図４及び図５に示すように吸着用吸入口２７２は、前板４６の吹出口４６ａの上側に設けられており、吹出口４６ａと同様に前板４６の前方に向かって開口している。吸着用吸入口２７２は前板４６の上部前方の空気を吸い込むが、吹出口４６ａから吹き出された空気を吸い込むことはない。なぜなら、室外ファン３９によって前方へ押し出された空気は、ベルマウス５２に沿って進み、吹出口４６ａから勢いよく吹き出されるからである。 Air containing moisture is sucked from the suction inlet 272, then flows through the suction duct 68, reaches the humidification rotor 63, and moisture is adsorbed when passing through the humidification rotor 63, and is discharged from the exhaust port 273. Is done. The exhaust port 273 is opposed to a space that becomes negative pressure when the outdoor fan 39 rotates, and air is absorbed by the suction port 272 by the principle that the air pressure on the exhaust port 273 side is lower than the suction port 272 side. Sucked from.
As shown in FIGS. 4 and 5, the suction inlet 272 is provided on the upper side of the air outlet 46a of the front plate 46, and is opened toward the front of the front plate 46 like the air outlet 46a. The suction inlet 272 sucks air in front of the upper portion of the front plate 46, but does not suck air blown from the outlet 46a. This is because the air pushed forward by the outdoor fan 39 travels along the bell mouth 52 and is blown out vigorously from the air outlet 46a.
　上記のような構成を採る目的は、より水分を含んだ空気を取り込むためである。通常、加湿運転は、暖房運転時に行われるので、室外熱交換器３３を通過した空気は低温低湿になっている。このため、低温空気が吸着用吸入口２７２から吸い込まれた場合、加湿ロータ６３が吸着することができる水分量が低下する。
　しかしながら、吸着用吸入口２７２が吹出空気を吸い込まない構成にしておけば、より水分を含んだ外気を取り込むことができるので、加湿ロータ６３が吸着する水分量が低下することを防止することができる。
　（４－３）ヒータ７１
　ヒータ７１は、放出部６２から水分を放出させるために、加湿ロータ６３の放出部６２の上方に設けられている。ヒータ７１は、加湿用吸入口７２から吸入されて加湿ロータ６３に送られる空気を加熱する。加熱された空気は、加湿ロータ６３を透過するときに加湿ロータ６３から水分を放出させて、高湿の空気となって加湿用第１ダクト７３に入る。 The purpose of adopting the above configuration is to take in more air containing moisture. Usually, since the humidification operation is performed during the heating operation, the air that has passed through the outdoor heat exchanger 33 has low temperature and low humidity. For this reason, when low-temperature air is sucked from the suction inlet 272, the amount of moisture that can be adsorbed by the humidifying rotor 63 is reduced.
However, if the suction inlet 272 is configured so as not to suck in the blown air, it is possible to take in outside air containing more moisture, thereby preventing the amount of moisture adsorbed by the humidifying rotor 63 from decreasing. .
(4-3) Heater 71
The heater 71 is provided above the discharge portion 62 of the humidification rotor 63 in order to release moisture from the discharge portion 62. The heater 71 heats the air sucked from the humidification inlet 72 and sent to the humidification rotor 63. When the heated air passes through the humidification rotor 63, moisture is released from the humidification rotor 63 and enters the humidification first duct 73 as high-humidity air.
　（４－４）加湿用第１ダクト７３
　図１において、加湿用第１ダクト７３は、加湿用吸入口７２から吸い込まれた空気をヒータ７１経由で放出部６２まで導き、さらに加湿ロータ６３を透過した空気をファン７５まで導く。加湿用吸入口７２から吸い込まれる空気の流れは、ファン７５によって発生する。
　加湿用吸入口７２から吸い込まれた空気は、ヒータ７１に加熱されて高温空気になり、さらに、加湿ロータ６３を透過する際に加湿ロータ６３から水分を放出させ高温高湿空気となってファン７５に向う。
　図４及び図５に示すように加湿用吸入口７２は、前板４６の吹出口４６ａの上側に設けられており、吹出口４６ａと同様に前板４６の前方に向かって開口している。加湿用吸入口７２は前板４６の上部前方の空気を吸い込むが、吹出口４６ａから吹き出された空気を吸い込むことはない。なぜなら、室外ファン３９によって前方へ押し出された空気は、ベルマウス５２に沿って進み、吹出口４６ａから勢いよく吹き出されるからである。 (4-4) Humidification first duct 73
In FIG. 1, the first humidifying duct 73 guides air sucked from the humidifying inlet 72 to the discharge portion 62 via the heater 71, and further guides air that has passed through the humidifying rotor 63 to the fan 75. A flow of air sucked from the humidifying inlet 72 is generated by the fan 75.
The air sucked from the humidification inlet 72 is heated by the heater 71 to become high-temperature air, and further, when passing through the humidification rotor 63, moisture is released from the humidification rotor 63 to become high-temperature high-humidity air. Towards.
As shown in FIGS. 4 and 5, the humidification inlet 72 is provided on the upper side of the air outlet 46a of the front plate 46, and is opened toward the front of the front plate 46 in the same manner as the air outlet 46a. The humidifying inlet 72 sucks air in front of the upper portion of the front plate 46, but does not suck air blown out from the outlet 46a. This is because the air pushed forward by the outdoor fan 39 travels along the bell mouth 52 and is blown out vigorously from the air outlet 46a.
　さらに、図２に示すように、遮蔽板７９が、防護グリル５６と前板４６との間に配置され、吹出口４６ａから吹き出される空気が進行する流路と加湿用吸入口７２とを仕切っているので、吹出口４６ａの縁から壁伝いに加湿用吸入口７２に空気が侵入することも防止されている。
　上記のような構成を採る目的は、ヒータ消費電力の増加を防止するためである。通常、加湿運転は、暖房運転時に行われるので、室外熱交換器３３を通過した空気は低温になっている。このため、低温空気が加湿用吸入口７２から吸い込まれた場合、ヒータ７１の発熱量を増やす必要がある。
　しかしながら、加湿用吸入口７２が吹出空気を吸い込まない構成にしておけば、ヒータ７１の発熱量を増やす必要もなく、ヒータ消費電力の増加を防止することができる。 Further, as shown in FIG. 2, a shielding plate 79 is disposed between the protective grill 56 and the front plate 46, and partitions the flow path through which the air blown from the air outlet 46a travels from the humidifying inlet 72. Therefore, it is possible to prevent air from entering the humidifying inlet 72 from the edge of the outlet 46a along the wall.
The purpose of adopting the above configuration is to prevent an increase in heater power consumption. Since the humidification operation is normally performed during the heating operation, the air that has passed through the outdoor heat exchanger 33 has a low temperature. For this reason, when low-temperature air is sucked from the humidifying inlet 72, the amount of heat generated by the heater 71 needs to be increased.
However, if the humidifying inlet 72 does not suck in the blown air, it is not necessary to increase the amount of heat generated by the heater 71, and an increase in heater power consumption can be prevented.
　（４－５）ファン７５
　ファン７５は、加湿空気を所定の方向へ送り出す羽根車７５ａと、その羽根車７５ａを駆動するファンモータ７５ｂとを有している。ファン７５は、羽根車７５ａの回転軸が鉛直方向となる姿勢で配置され、その上方にファンモータ７５ｂが位置し、羽根車７５ａの回転軸にファンモータ７５ｂの回転軸が直結されている。また、ファン７５は送風機室４１に配置され、室外熱交換器３３の空気流れの下流側に位置している。
　通常、加湿ユニット６０の稼動は暖房運転時に行われるので、室外熱交換器３３が蒸発器として機能しており、送風機室４１は機械室４２に比べて低温である。この低温の空気がファンモータ７５ｂを冷却するので、ファンモータ７５ｂの温度上昇は抑制される。
　また、図１に示すように、羽根車７５ａはファンケーシング８１に囲まれており、このファンケーシング８１と水平ダクト部１８１の入口とが繋がっている。ファンモータ７５ｂは、外側をモータカバー８２で覆われている。モータカバー８２は、径の異なる円筒を上下２段に重ねた形状をなしており、大径部８２ａの上に小径部８２ｂが載っている。小径部８２ｂは、完全な円筒形状ではなく、一部に切り欠き８２ｃが形成されている。この小径部８２ｂがファンモータ７５ｂを覆い、そのとき、切り欠き８２ｃは前板４６側を向いている。 (4-5) Fan 75
The fan 75 has an impeller 75a that sends humid air in a predetermined direction, and a fan motor 75b that drives the impeller 75a. The fan 75 is arranged in such a posture that the rotation shaft of the impeller 75a is in the vertical direction, the fan motor 75b is positioned above the fan 75, and the rotation shaft of the fan motor 75b is directly connected to the rotation shaft of the impeller 75a. The fan 75 is disposed in the blower chamber 41 and is located downstream of the air flow in the outdoor heat exchanger 33.
Normally, the operation of the humidifying unit 60 is performed during the heating operation, so the outdoor heat exchanger 33 functions as an evaporator, and the blower chamber 41 is at a lower temperature than the machine chamber 42. Since this low-temperature air cools the fan motor 75b, the temperature rise of the fan motor 75b is suppressed.
As shown in FIG. 1, the impeller 75 a is surrounded by a fan casing 81, and the fan casing 81 and the inlet of the horizontal duct portion 181 are connected. The fan motor 75b is covered with a motor cover 82 on the outside. The motor cover 82 has a shape in which cylinders with different diameters are stacked in two upper and lower stages, and a small-diameter portion 82b is placed on the large-diameter portion 82a. The small-diameter portion 82b is not completely cylindrical, and a notch 82c is formed in part. The small diameter portion 82b covers the fan motor 75b, and at that time, the notch 82c faces the front plate 46 side.
　ファンモータ７５ｂは冷却されるために送風機室４１側に置かれるので、モータカバー８２が完全にファンモータ７５ｂを覆うよりも切り欠き８２ｃを設けて、切り欠き８２ｃから冷風が入り込むようにしている方が好ましい。
　さらに、このモータカバー８２は、大径部８２ａによってファンケーシング８１をも覆っている。ファンケーシング８１が送風機室４１で低温に曝されると、内部の高温高湿空気の温度が低下して結露の要因になるが、モータカバー８２がファンケーシング８１の外側を覆うことによって、低温の空気はモータカバー８２の外周面に沿って流れるので、ファンケーシング８１が低温空気で直接冷却されることはなく、さらに、モータカバー８２によるファンケーシング８１の断熱効果も作用するので、ファンケーシング８１内部の加湿空気の温度低下を抑制することができる。 Since the fan motor 75b is placed on the blower chamber 41 side to be cooled, the motor cover 82 is provided with a notch 82c rather than completely covering the fan motor 75b, so that cold air enters from the notch 82c. Is preferred.
Further, the motor cover 82 also covers the fan casing 81 with a large diameter portion 82a. When the fan casing 81 is exposed to a low temperature in the blower chamber 41, the temperature of the internal high-temperature and high-humidity air decreases and causes condensation, but the motor cover 82 covers the outside of the fan casing 81, Since the air flows along the outer peripheral surface of the motor cover 82, the fan casing 81 is not directly cooled by the low-temperature air, and further, the heat insulating effect of the fan casing 81 by the motor cover 82 also acts. The temperature drop of the humidified air can be suppressed.
　また、室外機３０は室外に据え付けられるので、風雨時や室外機洗浄時には、背面部５０側から送風機室４１に水が進入する。しかし、ファンモータ７５ｂはモータカバー８２で覆われており、ファンモータ７５ｂへの水かかりは回避される。なお、モータカバー８２の切り欠き８２ｃは前板４６側を向いているので、水が切り欠き８２ｃから進入することは防止されている。
　本実施形態では、ファン７５は、羽根車７５ａの回転軸にファンモータ７５ｂの回転軸を直結させているが、これに限定されるものではなく、ファンモータ７５ｂの回転軸の回転をギアによって羽根車７５ａの回転軸に伝達する構成でもよい。この場合、少なくともファンモータ７５ｂが送風機室４１に配置され、室外熱交換器３３の空気流れの下流側に位置していればよい。 In addition, since the outdoor unit 30 is installed outside, water enters the blower chamber 41 from the back surface portion 50 side during wind and rain or during outdoor unit cleaning. However, the fan motor 75b is covered with the motor cover 82, and water splashing on the fan motor 75b is avoided. Since the notch 82c of the motor cover 82 faces the front plate 46, water is prevented from entering from the notch 82c.
In this embodiment, the fan 75 has the rotation shaft of the fan motor 75b directly connected to the rotation shaft of the impeller 75a. However, the present invention is not limited to this. The structure which transmits to the rotating shaft of the wheel 75a may be sufficient. In this case, at least the fan motor 75b may be disposed in the blower chamber 41 and positioned on the downstream side of the air flow of the outdoor heat exchanger 33.
　（４－６）加湿用第２ダクト１８０
　加湿用第２ダクト１８０は、ファン７５から押し出される高温高湿空気を給気ホース１８の接続口１８３まで導くダクトである。加湿用第２ダクト１８０のほぼ全体が機械室４２に位置しているが、給気ホース１８との接続口１８３を含む所定部分だけは、右側板４７を挟んで機械室４２の反対側に位置する。
　加湿用第２ダクト１８０は、水平ダクト部１８１と傾斜ダクト部１８２とを有している。水平ダクト部１８１は高温高湿空気を水平に導くダクトであり、傾斜ダクト部１８２は水平ダクト部１８１に流入した高温高湿空気を斜め下方に導くダクトである。水平ダクト部１８１は、送風機室４１と機械室４２との境界から右側板４７の後方端に向って延びている。したがって、水平ダクト部１８１の前方には台形状の空間が確保されており、そこに電装品ユニット５５が配置されている。 (4-6) Humidification second duct 180
The humidifying second duct 180 is a duct that guides the high-temperature and high-humidity air pushed out from the fan 75 to the connection port 183 of the air supply hose 18. Almost all of the second humidifying duct 180 is located in the machine room 42, but only a predetermined portion including the connection port 183 with the air supply hose 18 is located on the opposite side of the machine room 42 with the right side plate 47 interposed therebetween. To do.
The humidifying second duct 180 has a horizontal duct part 181 and an inclined duct part 182. The horizontal duct portion 181 is a duct that guides the high-temperature high-humidity air horizontally, and the inclined duct portion 182 is a duct that guides the high-temperature high-humidity air flowing into the horizontal duct portion 181 obliquely downward. The horizontal duct portion 181 extends from the boundary between the blower chamber 41 and the machine chamber 42 toward the rear end of the right side plate 47. Therefore, a trapezoidal space is secured in front of the horizontal duct portion 181, and the electrical component unit 55 is disposed there.
　なお、水平ダクト部１８１の長手方向ほぼ中央に、傾斜ダクト部１８２との接続口が設けられている。傾斜ダクト部１８２は、水平ダクト部１８１との接続口から下方且つ右側板４７方向に延び、右側板４７を貫通した直後に鉛直下方に曲げられ、所定長さだけ鉛直下方に進んで終端となる。この終端が、給気ホース１８との接続口１８３である。
　機械室４２の下部には圧縮機３１が設置されているので比較的温度が高く、傾斜ダクト部１８２については高温の圧縮機３１に近づくことによる温度低下抑制効果が期待される。これに対し、水平ダクト部１８１は、機械室４２の上部に位置しており、圧縮機３１の放熱による温度低下抑制効果は傾斜ダクト部１８２に比べて減少する。
　しかし、水平ダクト部１８１の高さ位置は、電装品ユニット５５の高さ方向の厚み範囲にかかるように配置されているので、その温度低下抑制効果の減少分は電装品ユニット５５の放熱を利用することによって補うことができる。 In addition, the connection port with the inclined duct part 182 is provided in the center of the horizontal duct part 181 in the longitudinal direction. The inclined duct portion 182 extends downward from the connection port with the horizontal duct portion 181 and toward the right side plate 47, is bent vertically downward immediately after passing through the right side plate 47, proceeds vertically downward by a predetermined length, and ends. . This end is a connection port 183 with the air supply hose 18.
Since the compressor 31 is installed in the lower part of the machine room 42, the temperature is relatively high, and the inclined duct portion 182 is expected to have a temperature lowering suppression effect by approaching the high-temperature compressor 31. On the other hand, the horizontal duct part 181 is located in the upper part of the machine room 42, and the temperature decrease suppressing effect due to the heat radiation of the compressor 31 is reduced compared to the inclined duct part 182.
However, since the height position of the horizontal duct portion 181 is arranged so as to cover the thickness range in the height direction of the electrical component unit 55, the decrease in the temperature decrease suppression effect uses the heat dissipation of the electrical component unit 55. You can make up for it.
　なお、「水平ダクト部１８１の高さ位置が電装品ユニット５５の高さ方向の厚み範囲にかかる」とは、電装品ユニット５５と水平ダクト部１８１とを前板４６側から視たとき、水平ダクト部１８１の厚みと、電装品ユニット５５の厚みとが重なるような位置関係にあることである。
　（４－７）フレーム６１０
　図２及び図５において、フレーム６１０は、送風機室４１と機械室４２とに跨る樹脂製部材である。前述の加湿ロータ６３、吸着用ダクト６８、ヒータ７１、加湿用第１ダクト７３、ファン７５、ファンケーシング８１、モータカバー８２、及び加湿用第２ダクト１８０は、フレーム６１０に組み込まれて加湿ユニット６０を構成する。
　（４－７－１）フレーム６１０と仕切板４３との位置関係
　本実施形態では、仕切板４３はフレーム６１０を境に上下に２分されており、以後、フレーム６１０より上側の仕切板を上部仕切板４３ａ、下側を下部仕切板４３ｂという。また、上部仕切板４３ａは樹脂製であり、下部仕切板４３ｂは板金製である。 Note that “the height position of the horizontal duct portion 181 falls within the thickness range in the height direction of the electrical component unit 55” means that when the electrical component unit 55 and the horizontal duct portion 181 are viewed from the front plate 46 side, That is, the thickness of the duct portion 181 and the thickness of the electrical component unit 55 are in a positional relationship.
(4-7) Frame 610
2 and 5, the frame 610 is a resin member straddling the blower chamber 41 and the machine chamber 42. The humidification rotor 63, the suction duct 68, the heater 71, the humidification first duct 73, the fan 75, the fan casing 81, the motor cover 82, and the humidification second duct 180 are incorporated in the frame 610 and are added to the humidification unit 60. Configure.
(4-7-1) Positional relationship between the frame 610 and the partition plate 43 In this embodiment, the partition plate 43 is divided into two parts up and down with the frame 610 as a boundary. The partition plate 43a and the lower side are referred to as a lower partition plate 43b. The upper partition plate 43a is made of resin, and the lower partition plate 43b is made of sheet metal.
　本実施形態の構成では、加湿ユニット６０は、ケーシング４０の上部から組み入れられるのが合理的であり、フレーム６１０が下部仕切板４３ｂに載り、上部仕切板４３ａがフレームに載る。それゆえ、下部仕切板４３ｂがフレーム６１０を下から支える構成となり、加湿ユニット６０の位置決めとして利用することができる。
　（４－７―２）上部仕切板４３ａ
　加湿ユニット６０の輪郭は周辺部材の輪郭に合わせて決定されるが、特に、加湿ユニット６０の上側は形状的制約を受け易く、それに従って上部仕切板４３ａも形状的制約を受ける。
　具体的には、図５に示すように、機械室４２内で且つフレーム６１０の上側には加湿用第２ダクト１８０の水平ダクト部１８１が位置するので、上部仕切板４３ａは水平ダクト部１８１との干渉をさけながら、且つ送風機室４１の空気が機械室４２に侵入しないように阻止しなければない。 In the configuration of the present embodiment, it is rational that the humidifying unit 60 is incorporated from the upper part of the casing 40, the frame 610 is placed on the lower partition plate 43b, and the upper partition plate 43a is placed on the frame. Therefore, the lower partition plate 43 b is configured to support the frame 610 from below, and can be used for positioning the humidifying unit 60.
(4-7-2) Upper partition plate 43a
The contour of the humidifying unit 60 is determined in accordance with the contours of the peripheral members. In particular, the upper side of the humidifying unit 60 is easily subject to shape restrictions, and the upper partition plate 43a is also subject to shape restrictions accordingly.
Specifically, as shown in FIG. 5, since the horizontal duct portion 181 of the humidifying second duct 180 is located in the machine room 42 and above the frame 610, the upper partition plate 43a is connected to the horizontal duct portion 181. And the air in the blower chamber 41 must be prevented from entering the machine chamber 42.
　図６は、加湿ユニット６０及び電装品ユニット５５の平面図である。図６において、上部仕切板４３ａは、水平ダクト部１８１のうち送風機室４１と対峙する壁面を覆いつつ、従来の仕切板のように天板４８まで鉛直上方に延び且つ室外熱交換器３３の右端から前方に向かって円弧状に延びる必要があり、複雑な形状が要求される。しかしながら、上部仕切板４３ａは樹脂製であるので、上記のような形状的制約に柔軟に対応することができる。さらに、本実施形態では、モータカバー８２と上部仕切板４３ａとを同一の樹脂材料で一体成形することによって、部品点数の削減を図っている。
　（４－７－３）下部仕切板４３ｂ
　また、下部仕切板４３ｂは、高さ方向の制約を除いては従来の形状を維持することができる。図５に示すように、下部仕切板４３ｂは、フレーム６１０の下面から底板４９側に向って右側板４７（図４参照）と略並行に延びている。また、下部仕切板４３ｂの幅方向は、室外熱交換器３３の右端から前方に向かって円弧状に延びている。その結果、下部仕切板４３ｂは送風機室４１から機械室４２に風が回り込まないように遮蔽することができる。 FIG. 6 is a plan view of the humidification unit 60 and the electrical component unit 55. In FIG. 6, the upper partition plate 43 a covers the wall facing the blower chamber 41 of the horizontal duct portion 181, extends vertically upward to the top plate 48 like a conventional partition plate, and extends to the right end of the outdoor heat exchanger 33. Therefore, a complicated shape is required. However, since the upper partition plate 43a is made of resin, it is possible to flexibly cope with the above-described shape restrictions. Further, in the present embodiment, the motor cover 82 and the upper partition plate 43a are integrally formed of the same resin material, thereby reducing the number of parts.
(4-7-3) Lower partition plate 43b
Moreover, the lower partition plate 43b can maintain the conventional shape except for the restriction in the height direction. As shown in FIG. 5, the lower partition plate 43b extends substantially in parallel with the right side plate 47 (see FIG. 4) from the lower surface of the frame 610 toward the bottom plate 49 side. Further, the width direction of the lower partition plate 43 b extends in an arc shape from the right end of the outdoor heat exchanger 33 toward the front. As a result, the lower partition plate 43b can be shielded from the wind from the blower chamber 41 to the machine chamber 42.
　（４－８）液閉鎖弁３７，ガス閉鎖弁３８と閉鎖弁カバー５７
　液閉鎖弁３７及びガス閉鎖弁３８は、図５に示すように、ケーシング４０の右側面下部に固定されている。液閉鎖弁３７及びガス閉鎖弁３８は、室内機２０からの冷媒配管１４，１６が接続される。液閉鎖弁３７及びガス閉鎖弁３８は、工場出荷時は閉じられているが、空気調和装置１０の据付が完了した後は開かれて冷媒が流れる状態となる。
　閉鎖弁カバー５７は、右側板４７に装着される。閉鎖弁カバー５７は、液閉鎖弁３７及びガス閉鎖弁３８と干渉しないように、予め下方部分が外側に凸となるように弁カバー部５７ａが成形されている。また、閉鎖弁カバー５７の上方部分も、給気ホース１８の接続口１８３と干渉しないよう外側に凸となるようにホースカバー部５７ｂが成形されている。 (4-8) Liquid closing valve 37, gas closing valve 38 and closing valve cover 57
As shown in FIG. 5, the liquid closing valve 37 and the gas closing valve 38 are fixed to the lower portion of the right side surface of the casing 40. The liquid closing valve 37 and the gas closing valve 38 are connected to the refrigerant pipes 14 and 16 from the indoor unit 20. The liquid closing valve 37 and the gas closing valve 38 are closed at the time of shipment from the factory, but after the installation of the air conditioning apparatus 10 is completed, the liquid closing valve 37 and the gas closing valve 38 are opened and the refrigerant flows.
The closing valve cover 57 is attached to the right side plate 47. The closing valve cover 57 is formed with a valve cover portion 57a in advance so that the lower portion is convex outward so as not to interfere with the liquid closing valve 37 and the gas closing valve 38. Further, the hose cover portion 57b is formed so that the upper portion of the shut-off valve cover 57 also protrudes outward so as not to interfere with the connection port 183 of the air supply hose 18.
　加湿用第２ダクト１８０の傾斜ダクト部１８２のうち右側板４７を出てから給気ホース１８の接続口１８３に至るまでの区間は、右側板４７とホースカバー部５７ｂとで囲まれた空間に位置する。右側板４７を出てから接続口１８３に至るまでの区間は、外気に触れて冷却されやすい部分である。この区間が右側板４７とホースカバー部５７ｂとで囲まれた空間に位置することによって、この区間の冷却が抑制され、その内部を通過する高温高湿空気の温度低下、およびその内部での結露が抑制される。
　（５）特徴
　（５－１）
　この室外機３０では、加湿用吸入口７２が室外熱交換器３３を通過した空気が流れる流路から外れた空間に設けられているので、室外熱交換器３３を通過した空気を取り入れる可能性がほぼ排除されている。その結果、吸入空気の温度低下によるヒータ７１の消費電力の増加を防止することができる。 The section from the right side plate 47 to the connection port 183 of the air supply hose 18 in the inclined duct portion 182 of the second humidifying duct 180 is surrounded by the right side plate 47 and the hose cover portion 57b. To position. The section from the right side plate 47 to the connection port 183 is a portion that is easily cooled by touching the outside air. Since this section is located in a space surrounded by the right side plate 47 and the hose cover portion 57b, cooling of this section is suppressed, and the temperature of high-temperature and high-humidity air passing through the section is reduced, and the condensation in the section Is suppressed.
(5) Features (5-1)
In the outdoor unit 30, since the humidification inlet 72 is provided in a space outside the flow path through which the air that has passed through the outdoor heat exchanger 33 flows, there is a possibility that air that has passed through the outdoor heat exchanger 33 is taken in. Almost eliminated. As a result, an increase in power consumption of the heater 71 due to a decrease in the temperature of the intake air can be prevented.
　（５－２）
　また、加湿用吸入口７２は吹出口４６ａに向って開口していないので、吹出口４６ａの空気を取り入れる可能性がほぼ排除されている。
　（５－３）
　また、加湿用吸入口７２はベルマウス５２の周縁より外側に位置するので、ベルマウス５２を通過した空気を取り入れる可能性がほぼ排除される。
　（５－４）
　さらに、遮蔽板７９が防護グリル４５と前板４６との間に配置され、吹出口４６ａから吹き出される空気が通る流路と加湿用吸入口７２とを仕切っている。それゆえ、防護グリル４５と前板４６との間を通って加湿用吸入口７２に進入しようとする空気を遮蔽板７９が阻止することができる。 (5-2)
Further, since the humidifying inlet 72 does not open toward the outlet 46a, the possibility of taking in air from the outlet 46a is almost eliminated.
(5-3)
Further, since the humidifying inlet 72 is located outside the peripheral edge of the bell mouth 52, the possibility of taking in air that has passed through the bell mouth 52 is almost eliminated.
(5-4)
Further, a shielding plate 79 is disposed between the protective grill 45 and the front plate 46, and partitions the flow path through which the air blown from the air outlet 46a passes and the humidifying inlet 72. Therefore, the shielding plate 79 can prevent air from entering the humidifying inlet 72 through the space between the protective grill 45 and the front plate 46.
　（５－５）
　この室外機３０では、水分を加湿ロータ６３に吸着させるために使用する吸着用吸入口２７２が、室外熱交換器３３を通過した空気が流れる流路から外れた空間に設けられている。その結果、水分量が減少した空気を取り入れる可能性がほぼ排除されるので、吸入空気の水分量低下による加湿性能の低下を防止することができる。 (5-5)
In the outdoor unit 30, the suction inlet 272 used for adsorbing moisture to the humidification rotor 63 is provided in a space that is out of the flow path through which the air that has passed through the outdoor heat exchanger 33 flows. As a result, the possibility of taking in air with a reduced amount of moisture is almost eliminated, so that it is possible to prevent a decrease in humidification performance due to a reduction in the amount of moisture in the intake air.
　以上のように、本願発明によれば、加湿ユニットを備えた空調室外機の室外機に限らず、仕切板によって空間を２分割されたケーシング内にそれら２つの空間を跨ぐように他のユニットが配置される機器にも有用である。 As described above, according to the present invention, not only an outdoor unit of an air-conditioning outdoor unit provided with a humidifying unit, but also other units so as to straddle the two spaces in a casing divided into two by a partition plate. It is also useful for the equipment to be placed.
