Description

本発明は、居室の壁を利用して空気調和する空気調和方法および空気調和機に関する。   The present invention relates to an air conditioning method and an air conditioner that perform air conditioning using a wall of a living room.
図10は、一般的な壁掛けタイプの空気調和機を構成する室内機1が居室の側壁に取り付けられ、冷房状態にある居室Rの透視斜視図である。従来の冷房時における空気調和方法の一例としては、居室Rの側壁に取り付けられた室内機1から調和空気を図10の矢印に示すように水平乃至下方向に送出して居室R内を冷房する。   FIG. 10 is a perspective view of the room R in which the indoor unit 1 constituting a general wall-hanging type air conditioner is attached to the side wall of the room and is in a cooling state. As an example of a conventional air conditioning method during cooling, the inside of the room R is cooled by sending conditioned air from the indoor unit 1 attached to the side wall of the room R horizontally or downward as indicated by the arrows in FIG. .
特開平10−185290公報(図1)JP-A-10-185290 (FIG. 1) 特開平6−347060公報(図1)JP-A-6-347060 (FIG. 1)
図11は、図10に示した居室Rを設定温度(28℃)で冷房運転した場合の安定状態における居室内の温度分布を示す図である。居室Rはマンション等の集合住宅の最上階に位置し、居室Rの大きさは6畳(高さ2400mm、横3600mm、奥行き2400mm)である。計測ポイントは図10に一点鎖線Dで示した居室Rの中央断面を600mm間隔で高さ方向と横方向にそれぞれ6点・8点の合計48点を計測している。また、冷房安定状態での気流は風量が微風で、吹出しの風向が略水平方向になっている。   FIG. 11 is a diagram showing the temperature distribution in the room in a stable state when the room R shown in FIG. 10 is cooled at a set temperature (28 ° C.). The living room R is located on the top floor of an apartment house such as an apartment, and the size of the living room R is 6 tatami mats (height 2400 mm, width 3600 mm, depth 2400 mm). The measurement points are a total of 48 points of 6 points and 8 points in the height direction and the horizontal direction at 600 mm intervals in the central cross section of the room R indicated by the alternate long and short dash line D in FIG. Further, the airflow in the cooling stable state has a slight air volume, and the blowing air direction is substantially horizontal.
同図によると、居室Rの天井壁近傍の上層部に設置温度28℃よりも室温が3℃乃至4℃高い領域が存在し、また、居室Rの中央部に設定温度28℃よりも約5℃低い領域が存在する。従って、居室Rの上部には略水平方向に等温線が現れ、8℃〜9℃の温度のばらつきが生ずる。即ち、居室R内の上下方向での温度ばらつきが大きくなるという問題があった。特に住宅の最上階の部屋においては上記のような温度分布になる傾向が極めて強い。また、屋上が太陽に熱せられて天井壁が熱源となるため居室R内の冷房が効率よく行なわれないといった問題もあった。また、空気調和機の室内機1周囲の温度は上記理由により高温になっており、空気調和機の室内機1の吹出口から送出される調和空気(図10のB')は、上記理由により高温になった室内機1周囲の空気よりも比重が大きく、そのため重力により下降し、居室R中央部の居住空間に降り注ぐ。同図によると、居室Rの中央部に設定温度28℃よりも約5℃低温の風が降り注いでいる。このため、設定温度付近に達した状態で送風を継続すると使用者に常に冷たい風が当たり続け、使用者に不快感を与えるとともに、局所的に使用者の体温を低下させて健康に害を与えるという課題があった。   According to the figure, there is a region where the room temperature is 3 ° C. to 4 ° C. higher than the installation temperature of 28 ° C. in the upper layer near the ceiling wall of the living room R, and about 5% higher than the set temperature of 28 ° C. in the center of the living room R. There is a region where the temperature is low. Therefore, an isotherm appears in the upper part of the living room R in a substantially horizontal direction, and a temperature variation of 8 ° C. to 9 ° C. occurs. That is, there is a problem that the temperature variation in the vertical direction in the living room R increases. In particular, the temperature distribution as described above tends to be extremely strong in the top floor room of the house. Moreover, since the roof was heated by the sun and the ceiling wall became a heat source, there was a problem that the cooling in the living room R was not performed efficiently. Further, the temperature around the indoor unit 1 of the air conditioner is high for the above reason, and the conditioned air (B ′ in FIG. 10) sent from the air outlet of the indoor unit 1 of the air conditioner is for the above reason. The specific gravity is larger than that of the air around the indoor unit 1 that has become high temperature, so that it descends due to gravity and falls into the living space in the center of the living room R. According to the figure, wind having a temperature lower by about 5 ° C. than the set temperature of 28 ° C. is pouring into the center of the living room R. For this reason, if the air flow is continued in the state where the temperature has reached the preset temperature, the cold wind will continue to hit the user, causing the user to feel uncomfortable, and locally lowering the user's body temperature and harming the health. There was a problem.
本発明は、上記の課題に鑑みてなされたものであり、熱を持った天井壁を冷却して吹出口から送出された調和空気がコアンダ効果により天井壁に沿って流れるようにすることにより居室内全体の温度分布を均一にする空気調和方法および空気調和機を提供することを目的とする。   The present invention has been made in view of the above problems, and by cooling the ceiling wall with heat and allowing the conditioned air sent from the blowout outlet to flow along the ceiling wall by the Coanda effect, An object of the present invention is to provide an air conditioning method and an air conditioner that make the temperature distribution of the entire inside uniform.

The air guide plate 14 is heat-insulated to prevent condensation.
図2は空気調和機の冷凍サイクルを示す回路図である。空気調和機の室内機1に接続される室外機(不図示)には、圧縮機62、四方切替弁63、室外熱交換器64、送風ファン65及び絞り機構66が設けられる。圧縮機62の一端は冷媒配管67により四方切替弁63を介して室外熱交換器64に接続されている。圧縮機62の他端は冷媒配管67により四方切替弁63を介して室内熱交換器9に接続されている。室外熱交換器64と室内熱交換器9とは冷媒配管67により絞り機構66を介して接続されている。   FIG. 2 is a circuit diagram showing a refrigeration cycle of the air conditioner. An outdoor unit (not shown) connected to the indoor unit 1 of the air conditioner is provided with a compressor 62, a four-way switching valve 63, an outdoor heat exchanger 64, a blower fan 65, and a throttle mechanism 66. One end of the compressor 62 is connected to an outdoor heat exchanger 64 through a four-way switching valve 63 by a refrigerant pipe 67. The other end of the compressor 62 is connected to the indoor heat exchanger 9 via a refrigerant pipe 67 via a four-way switching valve 63. The outdoor heat exchanger 64 and the indoor heat exchanger 9 are connected via a throttle mechanism 66 by a refrigerant pipe 67.
冷房運転を開始すると圧縮機62が駆動されるとともに送風ファン7が回転する。これにより、冷媒が圧縮機62、四方切替弁63、室外熱交換器64、絞り機構66、室内熱交換器9及び四方切替弁63を経て圧縮機62に戻る冷凍サイクル68が形成される。   When the cooling operation is started, the compressor 62 is driven and the blower fan 7 is rotated. Thus, a refrigeration cycle 68 is formed in which the refrigerant returns to the compressor 62 through the compressor 62, the four-way switching valve 63, the outdoor heat exchanger 64, the throttle mechanism 66, the indoor heat exchanger 9, and the four-way switching valve 63.
冷凍サイクル68の運転によって、冷房時には室内熱交換器9が周囲温度よりも低温に冷却される。また、暖房運転時には四方切替弁63が切り替えられて送風ファン65が回転し、上記と逆方向に冷媒が流通する。これにより、室内熱交換器9が周囲温度よりも高温に加熱される。   By operating the refrigeration cycle 68, the indoor heat exchanger 9 is cooled to a temperature lower than the ambient temperature during cooling. Further, during the heating operation, the four-way switching valve 63 is switched and the blower fan 65 rotates, and the refrigerant flows in the opposite direction to the above. Thereby, the indoor heat exchanger 9 is heated to a temperature higher than the ambient temperature.
上記構成の空気調和機において、冷房運転を開始すると、図1に示すように横ルーバ11a、11bは第1開口部5aが少しだけ開いた状態になるように設定され、導風板14は第2開口部5bが開放される位置に設定される。送風ファン7が回転駆動され、室外機(不図示)からの冷媒が室内熱交換器9へ流れて冷凍サイクルが運転される。これにより、室内機1内には吸込口4a、4cから空気が吸い込まれ、エアフィルタ8によって空気中に含まれる塵埃が除去される。   In the air conditioner having the above configuration, when the cooling operation is started, the horizontal louvers 11a and 11b are set so that the first opening 5a is slightly opened as shown in FIG. 2 The opening 5b is set to a position where it is opened. The blower fan 7 is rotationally driven, refrigerant from an outdoor unit (not shown) flows to the indoor heat exchanger 9, and the refrigeration cycle is operated. As a result, air is sucked into the indoor unit 1 from the suction ports 4 a and 4 c, and dust contained in the air is removed by the air filter 8.
室内機1内に取り込まれた空気は室内熱交換器9と熱交換し冷却される。そして、送風経路6及び分岐通路13を流通して吹出口の第2開口部5b及び横ルーバ11a、11bの隙間から矢印A2に示すように前方斜め上方すなわち居室Rの天井壁Sに向けて送出される。この時、分岐通路13の上壁面13aに沿って流通する空気は溝部28によってコアンダ効果が断ち切られ、矢印A2に示すようにフロントパネル3に沿うことなく前方斜め上方に導かれる。   The air taken into the indoor unit 1 is cooled by exchanging heat with the indoor heat exchanger 9. And it distribute | circulates through the ventilation path 6 and the branch channel | path 13, and sends out toward the ceiling wall S diagonally upward, ie, the living room R, as shown by arrow A2 from the clearance gap between the 2nd opening part 5b of a blower outlet, and the horizontal louvers 11a and 11b. Is done. At this time, the air flowing along the upper wall surface 13a of the branch passage 13 is cut off the Coanda effect by the groove 28, and is guided obliquely upward and forward along the front panel 3 as indicated by the arrow A2.
図3は前方斜め上方に送出された冷気流の居室R内での流れを示している。第1、第2開口部5a、5b(図1参照)から前方斜め上方に送出される空気流(B")は室内機1周辺の空気と熱交換しながら居室Rの天井壁Sに到達し、天井壁Sを結露しない程度に先ず冷却する。天井壁Sが冷却されて天井壁Sと空気流(B")との間に暖気が介在しにくくなってコアンダ効果が遠方まで持続することにより天井壁Sから室内機1に対向する壁面、床面、室内機1側の壁面を順次伝って室内機1の両側方から吸込口4a、4cに吸い込まれる。従って、室内機1からの直接風は居室R中央部即ち使用者の居住領域にほとんど降り注ぐことはない。   FIG. 3 shows the flow in the room R of the cold airflow sent obliquely upwards forward. The air flow (B ") sent from the first and second openings 5a and 5b (see FIG. 1) diagonally forward and forward reaches the ceiling wall S of the living room R while exchanging heat with the air around the indoor unit 1. First, the ceiling wall S is cooled to such an extent that the ceiling wall S does not condense.By the cooling of the ceiling wall S, it becomes difficult for warm air to intervene between the ceiling wall S and the air flow (B "), and the Coanda effect continues far away. The air is sucked into the suction ports 4a and 4c from the both sides of the indoor unit 1 through the wall surface, the floor surface facing the indoor unit 1 and the wall surface on the indoor unit 1 side in order from the ceiling wall S. Therefore, the direct wind from the indoor unit 1 hardly falls into the central part of the living room R, that is, the user's living area.
図4は、図3に示す居室Rを冷房運転した時に設定温度(28℃)付近に達した冷房安定状態における室内の温度分布を示している。居室Rの大きさは前述の図10および図11の従来例と同様に6畳(高さ2400mm、横3600mm、奥行き2400mm)であり、計測ポイントは図3に一点鎖線Dで示した居室Rの中央の断面を600mm間隔で高さ方向と横方向にそれぞれ6点・8点の合計48点を計測している。また、冷房安定状態での気流は風量が微風、風向が上方向になっている。   FIG. 4 shows the temperature distribution in the room in the stable cooling state that has reached the set temperature (28 ° C.) when the room R shown in FIG. The size of the room R is 6 tatami mats (height 2400 mm, width 3600 mm, depth 2400 mm) as in the conventional example of FIGS. 10 and 11 described above, and the measurement point of the room R indicated by the alternate long and short dash line D in FIG. A total of 48 points of 6 points and 8 points are measured on the central cross section at intervals of 600 mm in the height direction and the horizontal direction, respectively. Further, the airflow in the cooling stable state has a light air volume and a wind direction upward.
同図によると、居室Rの天井壁近傍に設置温度28℃よりも室温が2℃乃至3℃低い領域が存在し、天井壁Sが冷却されている様子がうかがえる。また、居室Rにおいて上記の領域を除いた場所全域、即ち使用者の居住領域全体が設定温度28℃に略一致して温度ばらつきがほとんどなくなっている。   According to the figure, there is an area where the room temperature is 2 ° C. to 3 ° C. lower than the installation temperature of 28 ° C. in the vicinity of the ceiling wall of the living room R, and it can be seen that the ceiling wall S is cooled. Further, in the living room R, the entire place excluding the above-described area, that is, the entire living area of the user substantially coincides with the set temperature 28 ° C., and the temperature variation is almost eliminated.
上記図3および図4から明らかなように、室内機1から送出された調和空気が天井壁Sを冷却し居室R全体を大きく攪拌するため、居室R内の温度分布が設定温度付近で均一になる。即ち、居室Rの上方の一部を除いて、使用者の居住領域全体が設定温度28℃に略一致して温度ばらつきが小さく直接風もほとんど使用者に当たることのない快適空間を得ることができる。   As is clear from FIGS. 3 and 4 above, the conditioned air sent from the indoor unit 1 cools the ceiling wall S and greatly agitates the entire room R, so that the temperature distribution in the room R is uniform around the set temperature. Become. In other words, except for a part above the living room R, the entire living area of the user substantially coincides with the set temperature of 28 ° C., and a comfortable space can be obtained in which the temperature variation is small and direct wind hardly hits the user. .
なお、空気調和機の室内機1は、調和空気を必要に応じて吹出口の第1開口部5aから図5の矢印A1に示すように略水平方向乃至下方向に向けて送出することもできる。図6はこの時の部屋全体の気流を示している。第1開口部5aから水平乃至下方向に送出される空気(B)は、居室R内を矢印に示すように流通して吸込口4a、4cに戻る。空気調和機の冷房運転開始直後、先ずこの空気調和方法にて居室R内を冷却し、居室R内の室温がやや低下した後、上記の天井壁Sを冷却する冷却方法に切り替えても良い。また、これらの制御をリモートコントローラによる使用者の指示により行なえるようにするとより望ましい。   In addition, the indoor unit 1 of an air conditioner can also send conditioned air from the first opening 5a of the air outlet in a substantially horizontal direction to a downward direction as indicated by an arrow A1 in FIG. . FIG. 6 shows the airflow of the entire room at this time. The air (B) sent from the first opening 5a horizontally or downward flows through the room R as indicated by the arrow and returns to the suction ports 4a and 4c. Immediately after the start of the cooling operation of the air conditioner, first, the room R may be cooled by this air conditioning method, and after the room temperature in the room R is slightly lowered, the cooling method may be switched to the cooling method for cooling the ceiling wall S. It is more desirable that these controls can be performed by a user's instruction from a remote controller.
次に、本発明の第2実施形態の空気調和方法および空気調和機について説明する。空気調和機の室内機の形式が図7に示す室内機1bに変更され、その他構成は上記第1実施形態と同一である。上記構成の空気調和機において、冷房運転を開始すると、図7に示すように吹出口5から天井壁Sに向けてA2の方向に気流が送出される。従って、空気調和方法については図3および図4に示す第1実施形態と略同一の結果となり、そのため上記第1実施形態と同様の効果を得ることができる。   Next, an air conditioning method and an air conditioner according to a second embodiment of the present invention will be described. The format of the indoor unit of the air conditioner is changed to the indoor unit 1b shown in FIG. 7, and the other configuration is the same as that of the first embodiment. In the air conditioner having the above-described configuration, when the cooling operation is started, an air flow is sent from the outlet 5 toward the ceiling wall S in the direction of A2, as shown in FIG. Therefore, the air conditioning method has substantially the same result as that of the first embodiment shown in FIGS. 3 and 4, and therefore, the same effect as that of the first embodiment can be obtained.
次に、本発明の第3実施形態の空気調和方法および空気調和機について説明する。第3実施形態の空気調和機は、ダクトエアコンや全館空調システムといった、居室R内に室内機が存在せず、図8のように居室Rの側壁に吹出口5が設置されたタイプの空気調和システム100である。居室Rの側壁に配置された吹出口5から調和空気が居室R内に送出され、吹出口5の略真下の位置には、居室R内の空気を外部に排出する吸込口4が配置されている。   Next, an air conditioning method and an air conditioner according to a third embodiment of the present invention will be described. The air conditioner of the third embodiment is a type of air conditioner in which there is no indoor unit in the living room R, such as a duct air conditioner or a whole building air conditioning system, and the air outlet 5 is installed on the side wall of the living room R as shown in FIG. System 100. Harmonic air is sent into the living room R from the air outlet 5 arranged on the side wall of the living room R, and a suction port 4 for discharging the air in the living room R to the outside is arranged at a position almost directly below the air outlet 5. Yes.
上記構成の空気調和機において、冷房運転を開始すると、図8に示すように吹出口5から前方上方即ち天井壁Sに向けて冷気流が送出される。図9は、図8に示す居室Rを冷房運転した時に設定温度(28℃)付近に達した冷房安定状態における室内の温度分布を示している。居室Rの大きさは前述の図10および図11の従来例と同様に6畳(高さ2400mm、横3600mm、奥行き2400mm)であり、計測ポイントは図3に一点鎖線Dで示した居室Rの中央の断面を600mm間隔で高さ方向と横方向にそれぞれ6点・8点の合計48点を計測している。   In the air conditioner having the above-described configuration, when the cooling operation is started, a cold airflow is sent out from the blowout port 5 toward the front upper side, that is, toward the ceiling wall S as shown in FIG. FIG. 9 shows a temperature distribution in the room in a stable cooling state that has reached the set temperature (28 ° C.) when the room R shown in FIG. The size of the room R is 6 tatami mats (height 2400 mm, width 3600 mm, depth 2400 mm) as in the conventional example of FIGS. 10 and 11 described above, and the measurement point of the room R indicated by the alternate long and short dash line D in FIG. A total of 48 points of 6 points and 8 points are measured on the central cross section at intervals of 600 mm in the height direction and the horizontal direction, respectively.
図8および図9から明らかなように、本実施形態においても図3および図4に示す第1実施形態と略同一の結果となり、そのため上記第1実施形態と同様の効果を得ることができる。   As is apparent from FIGS. 8 and 9, this embodiment also has substantially the same result as that of the first embodiment shown in FIGS. 3 and 4, so that the same effect as that of the first embodiment can be obtained.
なお、本実施形態の空気調和システム100は居室Rの側壁下部に吸込口4が設けられているが、これが省略されている場合や、図8に示されている以外の位置にあってもよい。その場合は居室R内の温度均一化の効果がやや劣化するが、吸込口4の位置に制約がなくなるため、居室Rの初期設計の自由度が高まる。   In addition, although the air inlet system 4 of the air conditioning system 100 of this embodiment is provided in the lower part of the side wall of the living room R, when this is abbreviate | omitted, it may exist in positions other than being shown by FIG. . In that case, although the effect of temperature equalization in the living room R is somewhat deteriorated, the position of the suction port 4 is not restricted, so the degree of freedom in the initial design of the living room R is increased.
以上、本発明に係る空気調和方法および空気調和機の実施形態を説明してきたが、本発明は上記実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で適宜の変更を加えて実施される。なお、居室Rが最上階に配される場合は天井壁Sを冷却するのが最も効果的であるが、居室Rが例えば西日が直接あたる位置に配されている場合には西側の側壁を冷却すればよく、居室Rが例えば南向きに配されている場合には南側の側壁を冷却すればよい。   The embodiments of the air conditioning method and the air conditioner according to the present invention have been described above, but the present invention is not limited to the above embodiments, and appropriate modifications are made without departing from the spirit of the present invention. Implemented. In addition, when the living room R is arranged on the top floor, it is most effective to cool the ceiling wall S. However, when the living room R is arranged, for example, in a position where the sun directly hits, the side wall on the west side is used. What is necessary is just to cool, and the living room R should just cool the south side wall, for example, when it is arranged southward.
