　図面を参照して、利用側熱交換器３側の空気の流れを詳細に説明する。図３Ａ、３Ｂには、本実施形態の屋外空気調和装置１００における、主な空気の流れを矢印に示してある。図４は吹出し口３１ａ、３１ｄ付近の詳細を示す図である。 (3) Configuration of Flowing Air in Outdoor Air Conditioner 100 and Description of Air Flow (3-1) Flow of Air on User-Side Heat Exchanger 3 Referring to the drawings, FIG. The flow of air will be described in detail. 3A and 3B, arrows indicate main air flows in the outdoor air conditioner 100 of the present embodiment. FIG. 4 is a diagram showing details in the vicinity of the outlets 31a and 31d.
　第２ファン４が運転されると、空気は、屋外空気調和装置１００の外部、４側面２０ａ～２０ｄの利用側熱交換器３の前面から、下化粧板２０２を通過して、中間板１６、１７の間の空間に取り込まれる。空気は、利用側熱交換器３を通過し、利用側熱交換器３において、冷媒と熱交換を行う。冷媒によって加熱または冷却された空気は、ベルマウス２６の内側、第２ファン４を通過し、中間板１５、１６の間の空間へ移動する。さらに、第２ファン４によって、空気は、４側面２０ａ～２０ｄに設けられた吹出し口３１ａ～３１ｄから外の空間に、横方向に吹出される。吹出し口３１ａ～３１ｄは、ケーシング１０に形成された穴である。ここで横方向とは、水平方向±３０°で定義する。本実施形態の屋外空気調和装置１００は、フラップ４０２を有しており、水平方向と、水平方向±３０°より広い角度に空気を吹出すことができる。フラップ４０２は、パネル５２に取り付けられている。フラップの向きを変更することにより、ある方向だけ全閉にして、特定の方向だけ空気の吹出しを封止することもできる。また、吹出し口３１ａ～３１ｄに用いる部材、フラップ４０２などは、耐候性材料を用いるか、表面に耐候性処理を施すのが好ましい。ここで耐候性材料の例としては、アクリロニトリルスチレン重合体などであるが、これに限定されない。 When the second fan 4 is operated, the air passes through the lower decorative plate 202 from the outside of the outdoor air conditioner 100, from the front side of the use side heat exchanger 3 on the four side surfaces 20a to 20d, and passes through the intermediate plate 16, It is taken into the space between 17. The air passes through the use-side heat exchanger 3 and performs heat exchange with the refrigerant in the use-side heat exchanger 3. The air heated or cooled by the refrigerant passes through the second fan 4 inside the bell mouth 26 and moves to the space between the intermediate plates 15 and 16. Further, the second fan 4 blows air laterally out of the outlets 31a to 31d provided on the four side surfaces 20a to 20d. The outlets 31a to 31d are holes formed in the casing 10. Here, the horizontal direction is defined as ± 30 ° in the horizontal direction. The outdoor air-conditioning apparatus 100 according to the present embodiment includes the flap 402, and can blow air in a horizontal direction and at an angle wider than ± 30 ° in the horizontal direction. Flap 402 is attached to panel 52. By changing the direction of the flap, it is possible to completely close the airbag in a certain direction and to seal the air blowing only in a specific direction. Further, it is preferable that the members used for the outlets 31a to 31d, the flap 402, and the like be made of a weather-resistant material or subjected to a weather-resistant treatment on the surface. Here, examples of the weather resistant material include an acrylonitrile styrene polymer, but are not limited thereto.
　（３－２）熱源側熱交換器６側の空気の流れ
　第１ファン７が運転されると、空気は、屋外空気調和装置１００の外部の、熱源側熱交換器６が配置されている前面から、上化粧板２０１を通過して、中間板１４、１５の間の空間に、取り込まれる。外気は、４側面２０ａ～２０ｄにおいて、取り込まれる。外部から取り込まれた空気は、熱源側熱交換器６を通過して、冷媒と熱交換を行う。冷媒によって、加熱または冷却された空気は、屋外空気調和装置１００の内部で第１ファン７、天板１３の中央の吹出し口２９を通過して、屋外空気調和装置１００の外の上部に、上向きに吹出される。 (3-2) Flow of Air on Heat Source-Side Heat Exchanger 6 When the first fan 7 is operated, air flows outside the outdoor air conditioner 100 on the front side where the heat source-side heat exchanger 6 is arranged. From the upper decorative board 201 and is taken into the space between the intermediate boards 14 and 15. The outside air is taken in on the four side surfaces 20a to 20d. The air taken in from the outside passes through the heat source side heat exchanger 6 and exchanges heat with the refrigerant. The air heated or cooled by the refrigerant passes through the first fan 7 and the outlet 29 at the center of the top plate 13 inside the outdoor air conditioner 100, and is directed upward to the upper part outside the outdoor air conditioner 100. To be blown out.
　（４）性能評価測定
　屋外空気調和装置１００について、室温３５℃の条件下で性能評価試験を行った。利用側熱交換器３は蒸発器として、熱源側熱交換器６は、凝縮器として作動させた。風は、一方向に吹出させた。吹出し温度は、２２℃である。第２吹出し口３１ａ～３１ｄの地面からの高さは１．２５ｍである。風速計としては、無指向性プローブを用いた。 (4) Performance Evaluation Measurement A performance evaluation test was performed on the outdoor air conditioner 100 at room temperature of 35 ° C. The use side heat exchanger 3 was operated as an evaporator, and the heat source side heat exchanger 6 was operated as a condenser. The wind was blown in one direction. The blowing temperature is 22 ° C. The height of the second outlets 31a to 31d from the ground is 1.25 m. An omnidirectional probe was used as the anemometer.
　標準的に、吹出し風速１５．２ｍ／ｓ、吹出し風量８ｍ３／ｍｉｎ（４方に合算すると３２ｍ３／ｍｉｎ相当）で風を吹出させたところ、次の結果を得た。 When the wind was blown off at a blowing wind speed of 15.2 m / s and a blowing air flow rate of 8 m 3 / min (equivalent to 32 m 3 / min when added in four directions), the following results were obtained.
　吹出し口から風下へ１．５ｍ離れたところで、温度はほぼ室温と同等になった。なお、吹出し風量を変化させても、この点は、ほとんど変化が無かった。また、吹出し口から風下へ３ｍ離れ、床面からの高さ０．５ｍの位置において、風速は、０．９ｍ／ｓであった。 温度 At a distance of 1.5 m downwind from the outlet, the temperature was almost equal to room temperature. It should be noted that there was almost no change in this point even when the blowing air volume was changed. The wind speed was 0.9 m / s at a position 3 m away from the outlet and leeward from the outlet and at a height of 0.5 m from the floor.
　今回の実験結果では、吹出し風速１５．２ｍ／ｓ以上、吹出し合算風量、３２ｍ３／ｍｉｎ以上であれば、吹出し口から３ｍ離れた位置で、床面から０．５ｍの高さ位置において、０．８ｍ／ｓ以上の風速を実現することができる。 According to the experimental results of this time, if the blowing air velocity is 15.2 m / s or more, and the total blowing air volume is 32 m 3 / min or more, 0 m at the position 3 m away from the outlet and 0.5 m above the floor surface. A wind speed of 0.8 m / s or more can be realized.
　（５）特徴
　（５－１）
　本実施形態の屋外空気調和装置１００は、一つのケーシング１０の中に、圧縮機１、熱源側熱交換器６、利用側熱交換器３、第１ファン７、第２ファン４を備えている。ケーシング１０には、第１吹出し口２９と、第２吹出し口３１ａ～３１ｄとが形成されている。第１吹出し口２９は、熱源側熱交換器６を通過した空気を、ケーシング１０の外部上方に向かって吹出す。第２吹出し口３１ａ～３１ｄは、第１吹出し口２９よりも下に配置された吹出し口である。第２吹出し口３１ａ～３１ｄは、利用側熱交換器３を通過した空気を、ケーシング１０の外部横方向に向かって吹出す。 (5) Features (5-1)
The outdoor air conditioner 100 of the present embodiment includes a compressor 1, a heat source side heat exchanger 6, a use side heat exchanger 3, a first fan 7, and a second fan 4 in one casing 10. . The casing 10 has a first outlet 29 and second outlets 31a to 31d. The first outlet 29 blows out the air that has passed through the heat source side heat exchanger 6 toward an upper portion outside the casing 10. The second outlets 31a to 31d are outlets disposed below the first outlet 29. The second outlets 31a to 31d blow the air that has passed through the use-side heat exchanger 3 toward the outside of the casing 10 in a lateral direction.
　本実施形態の屋外空気調和装置１００は、利用側熱交換器３を通過した空気をユーザーがいる方向へ、熱源側熱交換器６を通過した空気をユーザーのいない上方へ排気することができる。 The outdoor air-conditioning apparatus 100 according to the present embodiment can exhaust the air that has passed through the use-side heat exchanger 3 in a direction where a user is present and the air that has passed through the heat-source-side heat exchanger 6 upward without any user.
　本実施形態の屋外空気調和装置１００は、ケーシング１０に、利用側熱交換器３を通過した空気を吹出す第２吹出し口３１ａ～３１ｄが形成されている。別の言い方をすれば、エアガイドやダクトなどの別の流路を経由せずに、空気が吹出される。そのため、利用側熱交換器３を通過した空気の風速、風量、温度などが、あまり変化することなく、吹出すことができる。そこで、屋外空気調和装置１００の周りの空気を広い範囲に、効率良く空気調和することができる。 屋外 In the outdoor air conditioner 100 of the present embodiment, the casing 10 is formed with the second outlets 31a to 31d for blowing out the air that has passed through the use-side heat exchanger 3. In other words, air is blown out without passing through another flow path such as an air guide or a duct. Therefore, the air velocity, air volume, temperature, and the like of the air that has passed through the use-side heat exchanger 3 can be blown out without much change. Therefore, the air around the outdoor air conditioner 100 can be efficiently air-conditioned over a wide range.
　また、本実施形態の空気調和装置１００は、第２吹出し口３１ａ～３１ｄより、横方向に、空気を吹出す。したがって、吹出された空気は、空気調和装置１００より比較的離れた範囲まで到達することができ、比較的広いエリアの空気調和が可能である。 空 気 In addition, the air conditioner 100 of the present embodiment blows air in the lateral direction from the second outlets 31a to 31d. Therefore, the blown air can reach a range relatively far from the air conditioner 100, and air conditioning in a relatively large area is possible.
　さらに、本実施形態の空気調和装置１００においては、第１吹出し口２９は、熱源側熱交換器６を通過した空気を、ケーシング１０の外部上方に向かって吹出す。したがって、第１吹出し口の吹出し方向は、第２吹出し口３１ａ～３１ｄの横向きの吹出し方向と、干渉しにくいように構成されている。この効果は、特に第２吹出し口３１ａ～３１ｄが四方に向かって吹出す場合には顕著である。 Furthermore, in the air conditioner 100 of the present embodiment, the first outlet 29 blows the air that has passed through the heat source side heat exchanger 6 upward and outside the casing 10. Therefore, the blowout direction of the first blowout port is configured not to interfere with the lateral blowout direction of the second blowout ports 31a to 31d. This effect is particularly remarkable when the second outlets 31a to 31d blow out in all directions.
　また、特に冷房の場合には、凝縮器である熱源側熱交換器６を通過した暖気を上空に排気することになる。暖気は比較的軽く上に上りやすいので、円滑に排気することができる。 {Circle around (5)} Especially in the case of cooling, the warm air that has passed through the heat source side heat exchanger 6 which is a condenser is exhausted to the sky. Since the warm air is relatively light and easily rises, it can be exhausted smoothly.
　（５－２）
　本実施形態の屋外空気調和装置１００においては、第１吹出し口２９は、ケーシング１０の上面に配置されている。 (5-2)
In the outdoor air-conditioning apparatus 100 of the present embodiment, the first outlet 29 is arranged on the upper surface of the casing 10.
　本実施形態の屋外空気調和装置１００は、ケーシング１０の上面に第１吹出し口２９が設けられており、第１吹出し口２９から外部上方に向かって、熱源側熱交換器６を通過した空気が吹出されるので、よりユーザーに排気が到達しにくい。 In the outdoor air-conditioning apparatus 100 of the present embodiment, the first outlet 29 is provided on the upper surface of the casing 10, and the air that has passed through the heat-source-side heat exchanger 6 from the first outlet 29 to the outside upwards. Because it is blown out, it is more difficult for the exhaust to reach the user.
　（５－３）
　本実施形態の屋外空気調和装置１００は、第１吹出し口２９が、屋外空気調和装置１００の据付設置面から、１．６ｍ以上３ｍ以下の高さに配置されている。 (5-3)
In the outdoor air conditioner 100 of the present embodiment, the first outlet 29 is disposed at a height of 1.6 m or more and 3 m or less from the installation surface of the outdoor air conditioner 100.
　本実施形態の屋外空気調和装置１００は、第１吹出し口２９が、据付設置面から高い位置に設けられているので、排気を効率よく上空に導くことができる。 屋外 In the outdoor air conditioner 100 of the present embodiment, since the first outlet 29 is provided at a position higher than the installation surface, the exhaust air can be efficiently guided to the sky.
　（５－４）
　本実施形態の屋外空気調和装置１００は、第２吹出し口３１ａ～３１ｄが、前記屋外空気調和装置の据付設置面から、０．２ｍ以上１．６ｍ以下の高さに配置されている。 (5-4)
In the outdoor air conditioner 100 of the present embodiment, the second outlets 31a to 31d are arranged at a height of 0.2 m or more and 1.6 m or less from the installation surface of the outdoor air conditioner.
　本実施形態の屋外空気調和装置１００は、第２吹出し口３１ａ～３１ｄが据付設置面から適当な高さに配置され、かつ、横方向に吹出されるため、比較的離れた位置まで、調和空気を到達させることができる。また、この程度の高さであれば、ユーザーが立っていても座っていても上体の近くに、涼風または暖風が当たり、ユーザーに快適性を提供できる。 In the outdoor air conditioner 100 of the present embodiment, the second outlets 31a to 31d are arranged at an appropriate height from the installation surface and are blown out in the lateral direction. Can be reached. In addition, if the height is at this level, a cool or warm wind hits near the upper body even when the user is standing or sitting, and comfort can be provided to the user.
　（５－５）
　本実施形態の屋外空気調和装置１００においては、熱源側熱交換器６は、利用側熱交換器３よりも上に配置されている。 (5-5)
In the outdoor air conditioner 100 of the present embodiment, the heat source side heat exchanger 6 is disposed above the use side heat exchanger 3.
　本実施形態の屋外空気調和装置１００は、熱源側熱交換器６と第１吹出し口２９の距離を短くすることができる。したがって、ケーシング１０の中に余分な空気のパスをもうける必要が無い。また、利用側熱交換機と第２吹出し口３１ａ～３１ｄの距離も短くできる。第２吹出し口３１ａ～３１ｄを適当な高さにする構成も容易に選択できる。 屋外 In the outdoor air conditioner 100 of the present embodiment, the distance between the heat source side heat exchanger 6 and the first outlet 29 can be shortened. Therefore, there is no need to provide an extra air path in the casing 10. Further, the distance between the use side heat exchanger and the second outlets 31a to 31d can be shortened. A configuration in which the second outlets 31a to 31d are set at an appropriate height can be easily selected.
　また、本実施形態においては、熱源側熱交換器６と利用側熱交換器３は、離れて配置されている。両熱交換器の間には第２吹出し口３１ａ～３１ｄが配置されている。このような構成のため、両熱交換器の間の断熱は十分である。また一方の熱交換器を通過した空気がさらに他方の熱交換器と熱交換してしまうといった問題も生じにくい。 In addition, in the present embodiment, the heat source side heat exchanger 6 and the use side heat exchanger 3 are arranged apart from each other. Second outlets 31a to 31d are arranged between the two heat exchangers. Due to such a configuration, the heat insulation between the two heat exchangers is sufficient. Further, a problem that air passing through one heat exchanger further exchanges heat with the other heat exchanger hardly occurs.

If the wind speed is less than 12 m / s, the wind cannot reach far away.

　（６）変形例
　（６－１）変形例１Ａ
　第１実施形態においては、ケーシング１０の４側面全てに第２吹出し口３１ａ～３１ｄが形成されている場合について説明した。変形例１Ａの屋外空気調和装置では、一つの側面には、第２吹出し口が形成されていない。その他は第１実施形態と同様である。屋外といっても、特定の方向には、冷房または暖房を行う必要が無い場合も当然起こりうる。その場合に、一面に第２吹出し口を設けないようにすれば、より効率よくその他の方面に冷房、または暖房を行うことができる。また、２側面に第２吹出し口を設けない構成としてもよい。 (6) Modification (6-1) Modification 1A

In the outdoor air-conditioning apparatus of Modification Example 1A, the second outlet is not formed on one side surface. Others are the same as the first embodiment. Even if it is outdoors, it may occur naturally that there is no need to perform cooling or heating in a specific direction. In this case, if the second outlet is not provided on one side, cooling or heating can be performed more efficiently on the other side. Further, the configuration may be such that the second outlet is not provided on the two side surfaces.
　（６－２）変形例１Ｂ
　第１実施形態の屋外空気調和装置１００は、直方体状の形状を有している。変形例１Ｂの屋外空気調和装置１００は、円筒状の形状を有している。その他は基本的に第１実施形態と同様である。すなわち、屋外空気調和装置１００の上面視がほぼ円形である。この場合、屋外空気調和装置１００の側面は、一つの曲面である。第２吹出し口は、上面視で別の方向に２以上形成されている。ほぼ円の全周にわたって第２吹出し口が形成されていてもよい。屋外空気調和装置１００の上面視が楕円形であってもよい。 (6-2) Modification 1B

The outdoor air-conditioning apparatus 100 according to Modification 1B has a cylindrical shape. Others are basically the same as the first embodiment. That is, the top view of the outdoor air conditioner 100 is substantially circular. In this case, the side surface of the outdoor air conditioner 100 is one curved surface. Two or more second outlets are formed in different directions in a top view. The second outlet may be formed over substantially the entire circumference of the circle. The top view of the outdoor air conditioner 100 may be elliptical.
　（６－３）変形例１Ｃ
　第１実施形態の屋外空気調和装置１００においては、利用側熱交換器３はケーシング１０の４面に配置されている。変形例１Ｃの屋外空気調和装置１００においては、ケーシング１０の３側面のみに、利用側熱交換器３は配置されている。また、利用側熱交換器３の第２吹出し口と、その吸込み口と、熱源側熱交換器６と、その吸込み口は、同一の３側面のみに形成または配置されている。その他は第１実施形態と同様である。 (6-3) Modification 1C
In the outdoor air-conditioning apparatus 100 of the first embodiment, the use-side heat exchangers 3 are arranged on four surfaces of the casing 10. In the outdoor air-conditioning apparatus 100 according to Modification 1C, the use-side heat exchangers 3 are arranged only on three side surfaces of the casing 10. The second outlet of the use side heat exchanger 3, its inlet, the heat source side heat exchanger 6, and its inlet are formed or arranged only on the same three side surfaces. Others are the same as the first embodiment.
　変形例１Ｃの屋外空気調和装置１００は、このような構成にすることにより、コストを削減できる。また、屋外であっても、たとえば、壁際に空気調和装置を配置する場合に熱交換器に無駄な構成が無い。 屋外 The outdoor air-conditioning apparatus 100 of Modification 1C can reduce costs by adopting such a configuration. In addition, even when the air conditioner is placed outdoors, for example, when the air conditioner is arranged near a wall, the heat exchanger has no useless structure.
　変形例１Ｃの屋外空気調和装置１００は、３側面に形成する場合であるが、２側面であっても同様である。 屋外 The outdoor air-conditioning apparatus 100 according to Modification 1C is formed on three sides, but the same applies to two sides.
　また、変形例１Ｃは、利用側熱交換器３と、その吹出し口と、その吸込み口と、熱源側熱交換器６と、その吸込み口とが、同一の３側面のみに配置または形成されている場合について説明したが、揃って、３側面に構成されていなくてもよい。たとえば、利用側熱交換器３だけを３側面にすれば、その分、コストを削減することができる。 In the modification 1C, the use side heat exchanger 3, its outlet, its inlet, the heat source side heat exchanger 6, and its inlet are arranged or formed only on the same three side surfaces. Although the description has been given of the case where the three sides are provided, the three sides may not be configured. For example, if only the use-side heat exchanger 3 has three sides, the cost can be reduced accordingly.
　（６－４）変形例１Ｄ
　第１実施形態では、熱源側熱交換器６は利用側熱交換器３の上に配置されている。変形例１Ｄの場合、熱源側熱交換器６は利用側熱交換器３の下に配置されている。しかし、第１吹出し口２９と第２吹出し口３１ａ～３１ｄの位置は、第１実施形態と変更は無い。そのために、変形例１Ｄでは、熱源側熱交換器６を通過した空気の吹出し口２９と熱源側熱交換器を結ぶダクトを利用している。その他は、第１実施形態と同様である。両熱交換器の間に、第２吹出し口３１ａ～３１ｄが配置されているのも同様である。 (6-4) Modification 1D
In the first embodiment, the heat source side heat exchanger 6 is disposed on the use side heat exchanger 3. In the case of Modification 1D, the heat source side heat exchanger 6 is arranged below the use side heat exchanger 3. However, the positions of the first outlet 29 and the second outlets 31a to 31d are not changed from those of the first embodiment. For this purpose, in Modification 1D, a duct connecting the air outlet 29 of the air that has passed through the heat source side heat exchanger 6 and the heat source side heat exchanger is used. Others are the same as the first embodiment. Similarly, the second outlets 31a to 31d are arranged between the two heat exchangers.
　変形例１Ｄの場合、冷房時に次のようなメリットがある。冷房時、利用側熱交換器３である蒸発器においては、空気中の水分が凝縮して水滴が発生する。この水を一部熱源側熱交換器６に垂らす事により、システムの効率が向上する。変形例１Ｄにおいては、利用側熱交換器３である蒸発器が、熱源側熱交換器６である凝縮器の上に配置されているために、上から下へ水の輸送が簡単にできる。 In the case of Modification 1D, there are the following merits during cooling. During cooling, in the evaporator, which is the use-side heat exchanger 3, water in the air is condensed to generate water droplets. By dripping a part of this water to the heat source side heat exchanger 6, the efficiency of the system is improved. In the modification 1D, since the evaporator as the use side heat exchanger 3 is disposed on the condenser as the heat source side heat exchanger 6, water can be easily transported from top to bottom.
