Description

本発明は、空気調和機に関する。 The present invention relates to an air conditioner.

従来から、例えば、特許文献１に示すような空気調和機が知られている。この空気調和機は、暖房起動時に圧縮機構から室内熱交換器に向けて送られる冷媒の圧力が所定の高圧閾値に達するまで、室内ファンを停止させる。これにより、冷媒の圧力が高圧になるまでの時間を短縮させ、冷媒が高温にできるまでの時間を短縮させる。また、この空気調和機は、暖房起動時に、室内熱交換器を通過する冷媒の温度が所定の熱交温度に達するまで、室内ファンを停止させる室内熱交温度制御も選択的に行っている。 BACKGROUND ART Conventionally, for example, an air conditioner as shown in Patent Document 1 has been known. This air conditioner stops the indoor fan until the pressure of the refrigerant sent from the compression mechanism to the indoor heat exchanger reaches a predetermined high pressure threshold when heating is started. This shortens the time it takes for the refrigerant to reach a high pressure and shortens the time it takes for the refrigerant to reach a high temperature. This air conditioner also selectively performs indoor heat exchanger temperature control that stops the indoor fan until the temperature of the refrigerant passing through the indoor heat exchanger reaches a predetermined heat exchanger temperature when heating is started.

しかしながら、特許文献１に示すような従来の空気調和機により暖房起動時の温風を迅速に提供しようとする場合、暖房起動時に使用者の皮膚温度より低い風が使用者に当たることにより使用者の体感温度が下がり不快に感じる、いわゆるドラフト感を使用者に生じさせる問題がある。
一方で、このドラフト感を使用者に生じさせることを防ぐために、室内ファンを熱交温度に応じた風量となるように制御する場合には、暖房起動時における室内温度が比較的低いときに、熱交温度も比較的低くなり、室内ファンの風量が低下し、暖房起動時の目標室温への到達時間が比較的長くなるという問題が生じる。 However, when trying to quickly provide hot air when heating is started using a conventional air conditioner as shown in Patent Document 1, when heating is started, air with a temperature lower than the user's skin hits the user, causing There is a problem in that the user feels a so-called draft feeling, which causes the user to feel the temperature drop and feel uncomfortable.
On the other hand, in order to prevent the user from experiencing this draft feeling, when controlling the indoor fan so that the air volume corresponds to the heat exchanger temperature, when the indoor temperature at the time of starting the heating is relatively low, The heat exchanger temperature also becomes relatively low, the air volume of the indoor fan decreases, and the problem arises that it takes a relatively long time to reach the target room temperature when heating is started.

そこで、本発明は、暖房起動時に使用者の皮膚温度より低い風が使用者に当たることにより使用者の体感温度が下がり不快に感じる、いわゆるドラフト感を使用者に生じさせにくくしながらも、暖房起動時の目標室温への到達時間を短縮させることを目的としている。 Therefore, the present invention has been developed to prevent the user from experiencing the so-called draft feeling, in which the user feels uncomfortable due to a drop in the user's perceived temperature due to wind that is lower than the user's skin temperature hitting the user when the heating is started. The aim is to shorten the time it takes to reach the target room temperature.

上述した課題を解決するために、本発明は、冷媒を圧縮する圧縮機と、室内に空気を吹き出す室内ファンと、前記冷媒と前記室内ファンにより吹き出される空気とを熱交換する室内熱交換器と、室内温度を検出する室温検知部と、前記室内熱交換器における熱交温度を検出する熱交温度検知部と、外気と前記冷媒とを熱交換する室外熱交換器と、前記室内ファンを制御する制御部と、を備え、前記制御部は、暖房起動時に前記室内ファンから所定の小風量を吹き出す小風量モード及び前記室内ファンから所定の大風量を吹き出す大風量モードを含み、前記所定の大風量は、前記室内ファンから吹き出す風量の複数段階の設定範囲のうち最も多いレベルの風量を含む一定範囲内の段階のいずれか１つの段階の風量であって、前記所定の小風量から２以上大きい段階の風量であり、前記制御部は、暖房起動時における上記室内温度が第１温度未満である場合には、前記小風量モードを実行し、次に、前記熱交温度が暖房起動時からの上昇過程において人の皮膚温度に基づいて設定された第２温度から第３温度までの範囲内にあるとき、前記小風量モードに対応する前記所定の小風量から前記大風量モードに対応する前記所定の大風量まで上昇させ、前記大風量モードを実行し、前記制御部は、さらに、前記熱交温度が暖房起動時からの上昇過程において前記第２温度に到達して以後、前記熱交温度が前記第３温度に達するまでは、前記室内ファンの回転数を減少させないように制御することを特徴としている。
このように構成された本発明においては、制御部は、暖房起動時における室内温度が第１温度未満である場合には、小風量モードを実行し、次に、熱交温度が暖房起動時からの上昇過程において人の皮膚温度に基づいて設定された第２温度から第３温度までの範囲内にあるとき、大風量モードを実行する。これにより、暖房起動時に使用者の皮膚温度より低い風が使用者に当たることにより使用者の体感温度が下がり不快に感じる、いわゆるドラフト感を使用者に生じさせにくくしながらも、暖房起動時の目標室温への到達時間を短縮させることができる。
このように構成された本発明においては、制御部は、さらに、熱交温度が暖房起動時からの上昇過程において第２温度に到達して以後、熱交温度が第３温度に達するまでは、室内ファンの回転数を減少させないように制御する回転数非減少モードを備える。これにより、熱交温度が暖房起動時からの上昇過程において第２温度に到達して以後は、熱交温度が第２温度未満に低下したとしても、室内ファンにより大風量の供給を維持し、暖房起動時の目標室温への到達時間をより短縮させることができる。 In order to solve the above problems, the present invention provides a compressor that compresses a refrigerant, an indoor fan that blows air indoors, and an indoor heat exchanger that exchanges heat between the refrigerant and the air blown out by the indoor fan. a room temperature detection section that detects the indoor temperature; a heat exchanger temperature detection section that detects the heat exchanger temperature in the indoor heat exchanger; an outdoor heat exchanger that exchanges heat between the outside air and the refrigerant; and the indoor fan. and a control unit for controlling the mode, the control unit including a small air volume mode in which a predetermined small air volume is blown from the indoor fan when heating is started, and a large air volume mode in which a predetermined large air volume is blown out from the indoor fan, The large air volume is the air volume at any one stage within a certain range that includes the highest level of air volume among the multiple setting ranges of the air volume blown out from the indoor fan, and is equal to or greater than the predetermined small air volume. If the indoor temperature at the time of starting the heating is lower than the first temperature, the control unit executes the small air volume mode, and then the control unit executes the small air volume mode, and then the heat exchanger temperature changes from the time of starting the heating to the first temperature. is within the range from the second temperature to the third temperature set based on the human skin temperature in the rising process, from the predetermined small air volume corresponding to the small air volume mode to the predetermined small air volume corresponding to the large air volume mode. The controller further controls the heat exchanger temperature to increase to a predetermined large air volume and execute the large air volume mode, after the heat exchanger temperature reaches the second temperature in the rising process from heating startup. The indoor fan is controlled so as not to reduce its rotational speed until the indoor fan reaches the third temperature .
In the present invention configured in this way, the control unit executes the small air volume mode when the indoor temperature at the time of starting the heating is lower than the first temperature, and then the control unit executes the small air volume mode, and then changes the heat exchanger temperature from the time when the heating starts. When the temperature is within the range from the second temperature to the third temperature set based on the human skin temperature during the rising process, the large air volume mode is executed. As a result, when the heating is turned on, wind that is lower than the user's skin temperature hits the user, which lowers the user's perceived temperature and makes the user feel uncomfortable. The time required to reach room temperature can be shortened.
In the present invention configured in this way, the control section further includes: after the heat exchanger temperature reaches the second temperature in the rising process from the time of starting heating, until the heat exchanger temperature reaches the third temperature, It is equipped with a rotation speed non-reduction mode that controls the rotation speed of the indoor fan so as not to reduce it. As a result, after the heat exchanger temperature reaches the second temperature in the rising process from the heating start, even if the heat exchanger temperature drops below the second temperature, the indoor fan maintains the supply of a large air volume. The time required to reach the target room temperature when starting the heating can be further shortened.

本発明において、好ましくは、前記第１温度は、８℃～１２℃の範囲内に設定される。
このように構成された本発明においては、室内温度Ｂが８℃～１２℃の範囲内に設定された第１温度未満である場合に、小風量モード、大風量モード等の実行により、暖房起動時に使用者の皮膚温度より低い風が使用者に当たることにより使用者の体感温度が下がり不快に感じる、いわゆるドラフト感を使用者に生じさせにくくしながらも、暖房起動時の目標室温への到達時間を短縮させることができる。 In the present invention, preferably the first temperature is set within a range of 8°C to 12°C.
In the present invention configured in this way, when the indoor temperature B is lower than the first temperature set within the range of 8°C to 12°C, the heating is started by executing the small air volume mode, the large air volume mode, etc. The time it takes to reach the target room temperature when the heater is turned on, while preventing the user from experiencing the so-called draft feeling, which is when the user is exposed to wind that is lower than the user's skin temperature, lowering the user's perceived temperature and making them feel uncomfortable. can be shortened.

本発明において、好ましくは、前記第２温度は、２８℃～３３℃の範囲内に設定される。
このように構成された本発明においては、第２温度は、比較的低い室内温度に対応する人の皮膚温度に基づいて設定された、２８℃～３３℃の範囲内に設定されることができる。これにより、暖房起動時に使用者の皮膚温度より低い風が使用者に当たることにより使用者の体感温度が下がり不快に感じる、いわゆるドラフト感を使用者に生じさせにくくしながらも、暖房起動時の目標室温への到達時間を短縮させることができる。 In the present invention, preferably the second temperature is set within a range of 28°C to 33°C.
In the present invention configured in this way, the second temperature can be set within the range of 28°C to 33°C, which is set based on the human skin temperature corresponding to a relatively low indoor temperature. . As a result, when the heating is turned on, wind that is lower than the user's skin temperature hits the user, which lowers the user's perceived temperature and makes the user feel uncomfortable. The time required to reach room temperature can be shortened.

本発明において、好ましくは、前記第３温度は、３６℃～４０℃の範囲内に設定される。
このように構成された本発明においては、第３温度は、比較体高い室内温度に対応する人の皮膚温度に基づいて設定された、３６℃～４０℃の範囲内に設定されることができる。これにより、制御部は、熱交温度が第３温度より大きくなっていない場合に、熱交温度が依然として使用者の想定の皮膚温度の上限を超えるほどには上昇しておらず、大風量モードにより室内温度の上昇をより促進させることができる状態であると判断できる。 In the present invention, preferably the third temperature is set within a range of 36°C to 40°C.

As a result, when the heat exchanger temperature has not become higher than the third temperature, the control unit determines that the heat exchanger temperature has not yet risen to the extent that it exceeds the upper limit of the user's assumed skin temperature, and the control unit is able to set the high air volume mode. Therefore, it can be determined that the situation is such that the increase in indoor temperature can be further promoted.

以下、図１を参照して、本発明の一実施形態による空気調和機について説明する。
図１は本発明の一実施形態による空気調和機の概略構成図である。

The heat exchanger temperature sensor 26 detects a heat exchanger temperature that corresponds to the temperature of the refrigerant in a portion of the indoor heat exchanger 20 where the refrigerant is mainly in a two-phase region. In addition, since there is a correlation between the heat exchanger temperature and the air outlet temperature of the indoor unit 4, an air outlet temperature detection sensor is placed at the air outlet of the indoor unit 4 in place of the heat exchanger temperature sensor 26, and this air outlet temperature is Similar control may be performed by estimating the heat exchanger temperature from the blowout temperature detected by the detection sensor or from the blowout temperature.

制御装置８は、例えば室外機２の圧縮機１２、室外ファン１８及び膨張弁１６、室内機４の室内ファン２２、室内温度センサー２４、熱交温度センサー２６及びリモコンスイッチ１０と電気的に接続されている。制御装置８は、基板上に配置されたＣＰＵ及びメモリ等を備え、メモリ等に記憶された所定の制御プログラム、リモコンスイッチ１０から受信した指令信号等に基づいて、電気的に接続されている機器の制御を行うことができる。 The control device 8 is electrically connected to, for example, the compressor 12, outdoor fan 18, and expansion valve 16 of the outdoor unit 2, the indoor fan 22 of the indoor unit 4, the indoor temperature sensor 24, the heat exchanger temperature sensor 26, and the remote control switch 10. ing. The control device 8 includes a CPU, a memory, etc. arranged on a board, and controls electrically connected devices based on a predetermined control program stored in the memory, command signals received from the remote control switch 10, etc. can be controlled.

大風量設定は、室内機４からの吹き出しの風量Ａ（図３参照）の小風量から大風量までの設定範囲のうち、最も多いレベルの風量の段階に設定される。なお、大風量設定は、必ずしも吹き出しうる最高の風量である必要はなく、最も多いレベルの風量を含む一定範囲内の風量で設定されればよい。例えば、大風量設定は、小風量から大風量までの３段階又は５段階の設定範囲のうち、最も多い風量の段階として設定される。大風量設定は、空気調和機１の出力に対応する大風量として設定され、３．５ｋｗの出力に対応する大風量は例えば１１[ｍ3／ｍｉｎ]であり、５ｋｗの出力に対応する大風量は例えば１３[ｍ3／ｍｉｎ]である。 If the indoor temperature B at the time of starting the heating is less than 10° C. (first temperature B1), the control device 8 sets the indoor heat exchanger temperature C based on the human skin temperature during the rising process from the time of starting the heating. A large air volume mode at heating startup is provided in which the indoor fan 22 is driven at a rotation speed corresponding to the large air volume setting when the temperature is within the range of 32°C (second temperature C2) to 38°C (third temperature C3). . Here, the above-mentioned 10°C (first temperature B1) may be within the range of 8°C to 12°C, and 32°C (second temperature C2) may be within the range of 28°C to 33°C.

The large air volume setting is set to the highest level of air volume within the setting range of the air volume A (see FIG. 3) blown out from the indoor unit 4 from a small air volume to a large air volume. Note that the large air volume setting does not necessarily have to be the maximum air volume that can be blown out, but may be set to an air volume within a certain range that includes the highest level of air volume. For example, the large air volume setting is set as the stage with the highest air volume among the three or five setting ranges from small air volume to large air volume. The large air volume setting is set as a large air volume that corresponds to the output of the air conditioner 1, and the large air volume that corresponds to an output of 3.5 kW is, for example, 11 [m 3 /min], and the large air volume that corresponds to an output of 5 kW. is, for example, 13 [m 3 /min].

(first temperature B1), the control device 8 further controls the indoor heat exchanger temperature C to be 32° C. (second temperature B1) in the process of increasing from the time starting heating. Until C2) is reached, a small air volume mode at heating startup is provided in which the indoor fan 22 is driven at a rotation speed corresponding to the small air volume setting. The small air volume setting is set to the lowest air volume level within the setting range of the air volume A (see FIG. 3) from the small air volume to the large air volume blown out from the indoor unit 4. Note that the small air volume setting does not necessarily have to be the lowest air volume that can be blown out, but may be set to an air volume within a certain range that includes the lowest level of air volume. For example, the small air volume setting is set as the lowest air volume level among the three or five setting ranges from small air volume to large air volume.
The control device 8 further controls the indoor heat exchanger temperature C to reach 38°C (third temperature C3) after the indoor heat exchanger temperature C reaches 32°C (second temperature C2) in the rising process from the time of starting heating. A rotation speed non-reduction mode is provided in which the rotation speed of the indoor fan 22 is controlled so as not to decrease until the rotation speed is reached.

つぎに、図２により、本発明の一実施形態による空気調和機の暖房起動時の制御内容について説明する。図２において、Ｓは各ステップを示している。 Next, referring to FIG. 2, a description will be given of the control contents when the air conditioner starts heating according to an embodiment of the present invention. In FIG. 2, S indicates each step.

図２に示すように、最初に、Ｓ１において、使用者がリモコンスイッチ１０を操作して暖房の操作指令を制御装置８に送信し、空気調和機１の暖房運転を開始させる。 As shown in FIG. 2, first, in S1, the user operates the remote control switch 10 to transmit a heating operation command to the control device 8, thereby starting the heating operation of the air conditioner 1.

次に、Ｓ２に進み、暖房起動時における室内温度Ｂが１０℃（第１温度Ｂ１）未満か否かを判定する。室内温度Ｂが１０℃未満でない場合には、居室の室内温度Ｂが比較的高く、熱交温度対応風量制御モードにより比較的早く室内中央を目標室温まで暖房できる環境であると判断できるので、Ｓ８に進み、通常の熱交温度に対応した風量を吹き出す熱交温度対応制御モードを実行する。
制御装置８は、室内温度Ｂが１０℃未満である場合には、居室の室内温度Ｂが１０℃未満の比較的低い温度であり、暖房起動時小風量モード、回転数非減少モード、暖房起動時大風量モード等の実行により、熱交温度対応風量制御モードの実行によるよりも早期に室内中央を目標室温まで暖房できる環境であると判断できるので、Ｓ３に進む。 Next, the process proceeds to S2, and it is determined whether the indoor temperature B at the time of starting the heating is less than 10° C. (first temperature B1). If the indoor temperature B is not less than 10°C, it can be determined that the indoor temperature B of the living room is relatively high and the environment is such that the center of the room can be heated to the target room temperature relatively quickly using the heat exchanger temperature corresponding air volume control mode. Proceed to , and execute the heat exchanger temperature compatible control mode that blows out the air volume corresponding to the normal heat exchanger temperature.
When the indoor temperature B is less than 10°C, the control device 8 determines that the indoor temperature B of the living room is a relatively low temperature of less than 10°C, and selects a small air volume mode when starting the heating, a non-reducing rotational speed mode, and a heating starting mode. By executing the large air volume mode or the like, it can be determined that the environment is such that the center of the room can be heated to the target room temperature earlier than by executing the heat exchanger temperature corresponding air volume control mode, so the process proceeds to S3.

次に、Ｓ３に進み、制御装置８は、上述した暖房起動時小風量モードを実行する。
次に、Ｓ４に進み、室内熱交温度Ｃが暖房起動時からの上昇過程において人（使用者）の皮膚温度に基づいて設定された３２℃（第２温度Ｃ２）以上となるか否かを判定する。３２℃（第２温度Ｃ２）は、室内温度Ｂが１０℃未満であるような低温環境における人の皮膚温度として設定される。 Next, the process proceeds to S3, and the control device 8 executes the above-described small air volume mode at heating startup.
Next, the process proceeds to S4, where it is determined whether or not the indoor heat exchanger temperature C becomes 32°C (second temperature C2) or higher, which is set based on the skin temperature of the person (user) during the rising process from the start of heating. judge. 32°C (second temperature C2) is set as the human skin temperature in a low-temperature environment where the indoor temperature B is less than 10°C.

室内熱交温度Ｃが３２℃（第２温度Ｃ２）以上ではないと判定された場合には、Ｓ３に戻り、暖房起動時小風量モードの実行を継続する。 If it is determined that the indoor heat exchanger temperature C is not higher than 32° C. (second temperature C2), the process returns to S3 and continues execution of the small air volume mode at heating startup.

Ｓ４において、室内熱交温度Ｃが３２℃（第２温度Ｃ２）以上であると判定された場合には、Ｓ５に進む。 If it is determined in S4 that the indoor heat exchanger temperature C is equal to or higher than 32° C. (second temperature C2), the process proceeds to S5.

Ｓ５において、制御装置８は室内熱交温度Ｃが３２℃（第２温度Ｃ２）以上と判定された場合には、上述した暖房起動時大風量モードを実行する。 In S5, if the control device 8 determines that the indoor heat exchanger temperature C is equal to or higher than 32° C. (second temperature C2), the control device 8 executes the above-described large air volume mode at heating startup.

次に、Ｓ６に進み、制御装置８は暖房起動時大風量モードの実行の開始と並行して、回転数非減少モードを実行する。
この回転数非減少モードを実行することにより、室内熱交温度Ｃが３２℃（第２温度Ｃ２）よりも下降したとしても、室内機４から吹き出す風量を大風量Ａ２に維持し、室内温度Ｂの上昇を促進させ、暖房起動時の目標室温への到達時間をより短縮させる。 Next, the process proceeds to S6, and the control device 8 executes the rotation speed non-reducing mode in parallel with the start of the execution of the heating start-up large air volume mode.
By executing this rotation speed non-reducing mode, even if the indoor heat exchanger temperature C falls below 32°C (second temperature C2), the air volume blown from the indoor unit 4 is maintained at the large air volume A2, and the indoor temperature B This accelerates the rise in room temperature and further shortens the time it takes to reach the target room temperature when starting heating.

次に、Ｓ７に進み、制御装置８は室内熱交温度Ｃが暖房起動時からの上昇過程において人の皮膚温度に基づいて設定された３８℃（第３温度Ｃ３）より高温であるか否かを判定する。３８℃（第３温度Ｃ３）は、室内温度Ｂが暖房起動時の温度よりも上昇し且つ目標室温以下であるような環境における人の想定上限の皮膚温度である。 Next, the process proceeds to S7, and the control device 8 determines whether the indoor heat exchanger temperature C is higher than 38°C (third temperature C3) set based on the human skin temperature during the rising process from the heating start. Determine. 38° C. (third temperature C3) is the assumed upper limit skin temperature of a person in an environment where the indoor temperature B is higher than the temperature at the time of starting the heating and is below the target room temperature.

制御装置８は、室内熱交温度Ｃが３８℃（第３温度Ｃ３）より高温ではない場合、すなわち３８℃以下の場合には、室内熱交温度Ｃが依然として使用者の想定の皮膚温度の上限を超えるほどには上昇しておらず、暖房起動時大風量モードにより室内温度Ｂの上昇をより促進させることができる状態であると判断できるので、Ｓ５に戻る。
制御装置８は、室内熱交温度Ｃが３８℃（第３温度Ｃ３）より高温となっていると判定される場合には、Ｓ８に進む。Ｓ８では、室内熱交温度Ｃが使用者の想定上限の皮膚温度を超える程度まで上昇しているので、通常の熱交温度対応風量制御モードを実行する。 When the indoor heat exchanger temperature C is not higher than 38°C (third temperature C3), that is, when it is below 38°C, the control device 8 controls the indoor heat exchanger temperature C to still be the upper limit of the user's assumed skin temperature. , and it can be determined that the state is such that the increase in indoor temperature B can be further promoted by the large air volume mode at heating startup, so the process returns to S5.
If it is determined that the indoor heat exchanger temperature C is higher than 38° C. (third temperature C3), the control device 8 proceeds to S8. In S8, since the indoor heat exchanger temperature C has risen to an extent exceeding the assumed upper limit skin temperature of the user, the normal heat exchanger temperature corresponding air volume control mode is executed.

次に、図２及び図３により、本発明の一実施形態による空気調和機及び比較例の空気調和機による暖房起動時の風量、室内温度、熱交換器温度と時間との関係を説明する。
図２のＳ１において、使用者が空気調和機１の暖房運転を開始させる。空気調和機１の暖房運転の開始時間（開始時刻）は、図３において時間ｔ０により示される。時間ｔ０における室内温度Ｂは、室内温度Ｂ０であり、室内熱交温度Ｃもほぼ室内温度Ｂ０と同じ温度となっている。室内温度Ｂ０が１０℃未満の比較的低い温度となっている。 Next, with reference to FIGS. 2 and 3, the relationship between the air volume, room temperature, heat exchanger temperature, and time when heating is started by the air conditioner according to the embodiment of the present invention and the air conditioner of the comparative example will be described.
In S1 of FIG. 2, the user starts the heating operation of the air conditioner 1. The start time (start time) of the heating operation of the air conditioner 1 is indicated by time t0 in FIG. The indoor temperature B at time t0 is the indoor temperature B0, and the indoor heat exchanger temperature C is also approximately the same temperature as the indoor temperature B0. The indoor temperature B0 is relatively low, less than 10°C.

制御装置８はＳ３において暖房起動時小風量モードを実行する。時間ｔ１において室内熱交温度Ｃが所定温度Ｃ１まで上昇すると、室内ファン２２が起動される。室内ファン２２が小風量設定に対応する回転数で回転されるので、室内機４から小風量Ａ１の内気が室内に吹出される。時間ｔ１以後、室内熱交温度Ｃは引き続き上昇する。制御装置８は、室内熱交温度Ｃが上昇したとしても、小風量運転を継続し、室内ファン２２を小風量設定に対応する回転数に維持する。室内機４からは小風量Ａ１の内気が吹出されるのみであるので、室内の室内温度Ｂは、時間ｔ１から後述する時間ｔ２まで室内温度Ｂ０でありほぼ一定となっている。 The control device 8 executes the small air volume mode at heating startup in S3. When the indoor heat exchanger temperature C rises to a predetermined temperature C1 at time t1, the indoor fan 22 is activated. Since the indoor fan 22 is rotated at a rotation speed corresponding to the small air volume setting, the indoor air with the small air volume A1 is blown into the room from the indoor unit 4. After time t1, the indoor heat exchanger temperature C continues to rise. Even if the indoor heat exchanger temperature C rises, the control device 8 continues the small air volume operation and maintains the indoor fan 22 at the rotation speed corresponding to the small air volume setting. Since the indoor unit 4 only blows out the inside air at a small air volume A1, the indoor temperature B in the room remains almost constant at the indoor temperature B0 from time t1 to time t2, which will be described later.

制御装置８は、Ｓ４に進み、室内熱交温度Ｃが３２℃（第２温度Ｃ２）以上となるか否かを判定する。室内熱交温度Ｃが３２℃以上でないと判定される場合には、室内熱交温度Ｃが依然として人の皮膚温度に到達しておらず、仮に風量を増大させてしまうと、使用者の皮膚温度より低い風が暖房時に使用者に当たることにより使用者の体感温度が下がり不快に感じる、いわゆるドラフト感を使用者に生じさせてしまう可能性があると判断されるので、Ｓ３に戻る。
Ｓ４において、室内熱交温度Ｃが３２℃以上であると判定された場合には、室内熱交温度Ｃが使用者の皮膚温度に到達しており、仮に風量を増大させたとしても、使用者の皮膚温度より高い風が暖房時に使用者に当たり、いわゆるドラフト感を使用者に生じさせにくいと判断されるので、Ｓ５に進む。 The control device 8 proceeds to S4 and determines whether the indoor heat exchanger temperature C becomes 32° C. (second temperature C2) or higher. If it is determined that the indoor heat exchanger temperature C is not 32°C or higher, the indoor heat exchanger temperature C has not yet reached the human skin temperature, and if the air volume is increased, the user's skin temperature will increase. Since it is determined that there is a possibility that the user may experience a so-called draft feeling in which the user's sensible temperature decreases and the user feels uncomfortable due to the lower temperature wind hitting the user during heating, so the process returns to S3.
In S4, if it is determined that the indoor heat exchanger temperature C is 32°C or higher, the indoor heat exchanger temperature C has reached the user's skin temperature, and even if the air volume is increased, the user's Since it is determined that air having a temperature higher than the skin temperature of the user hits the user during heating and is unlikely to cause a so-called draft feeling to the user, the process proceeds to S5.

Ｓ５において、室内ファン２２を小風量設定に対応する回転数ａ１から大風量設定に対応する回転数ａ２まで上昇させる。室内ファン２２が回転数ａ２で回転されるので、室内機４から大風量Ａ２の内気が室内に吹出される。時間ｔ２以後、室内熱交温度Ｃは一旦第２温度Ｃ２よりも下降する。 In S5, the indoor fan 22 is increased from the rotation speed a1 corresponding to the small air volume setting to the rotation speed a2 corresponding to the large air volume setting. Since the indoor fan 22 is rotated at the rotation speed a2, a large volume of air A2 of indoor air is blown into the room from the indoor unit 4. After time t2, the indoor heat exchanger temperature C once falls below the second temperature C2.

Ｓ６において、制御装置８は、時間ｔ２以後回転数非減少モードを実行することにより、室内熱交温度Ｃが暖房起動時からの上昇過程において３２℃に到達して以後、室内熱交温度Ｃが３８℃に達するまでは、室内ファン２２の回転数を減少させないように制御する。よって、室内熱交温度Ｃが第２温度Ｃ２未満に低下したとしても、制御装置８は、室内ファン２２の回転数を下降させず回転数ａ２に維持する。よって、室内熱交温度Ｃが第２温度Ｃ２よりも下降したとしても、室内機４から吹き出す風量を大風量Ａ２に維持し、室内温度Ｂの上昇を促進させ、暖房起動時の目標室温への到達時間をより短縮させる。時間ｔ２以後は、室内機４からは大風量Ａ２の内気が継続して吹出されるので、室内の室内温度Ｂは、時間ｔ２から大きく上昇し、且つ上昇を継続している。このように制御装置８は、暖房起動時大風量モード及び回転数非減少モードを実行した状態で、Ｓ７に進む。 In S6, the control device 8 executes the rotation speed non-reducing mode after time t2, so that after the indoor heat exchanger temperature C reaches 32°C in the rising process from the start of the heating, the indoor heat exchanger temperature C increases. The rotation speed of the indoor fan 22 is controlled not to be reduced until the temperature reaches 38°C. Therefore, even if the indoor heat exchanger temperature C falls below the second temperature C2, the control device 8 maintains the rotation speed of the indoor fan 22 at the rotation speed a2 without decreasing the rotation speed. Therefore, even if the indoor heat exchanger temperature C falls below the second temperature C2, the air volume blown out from the indoor unit 4 is maintained at the large air volume A2, promoting the rise in the indoor temperature B, and achieving the target room temperature at the time of starting heating. Reduce arrival time. After time t2, the indoor unit 4 continues to blow out the indoor air at a large amount A2, so the indoor temperature B in the room has increased significantly since time t2 and continues to increase. In this manner, the control device 8 proceeds to S7 while executing the heating start-up large air volume mode and the rotation speed non-reducing mode.

Ｓ７において、時間ｔ３において室内熱交温度Ｃが３８℃より大きくなったと判定された場合、制御装置８は、暖房起動時大風量モード及び回転数非減少モードの実行を終了し、熱交温度対応風量制御モードの実行を開始させる。時間ｔ３において、熱交温度対応風量制御モードにより、室内熱交温度Ｃに基づき、室内ファン２２の回転数が回転数ａ２からわずかに引き上げられて回転数ａ３となっている。室内ファン２２が回転数ａ３で回転されるので、室内機４から大風量Ａ３の内気が室内に吹出される。時間ｔ３以後、室内熱交温度Ｃは、わずかに上昇を継続するものの、変動幅は小さくされ、安定する。時間ｔ３以後、室内熱交温度Ｃに対応して室内ファン２２の回転数は回転数ａ３でほぼ一定となっている。 In S7, if it is determined that the indoor heat exchanger temperature C has become higher than 38° C. at time t3, the control device 8 ends the execution of the large air volume mode at heating startup and the rotation speed non-reduction mode, and changes the temperature corresponding to the heat exchanger temperature. Starts execution of air volume control mode. At time t3, the number of revolutions of the indoor fan 22 is slightly increased from the number of revolutions a2 to the number of revolutions a3 based on the indoor heat exchanger temperature C by the air volume control mode corresponding to the heat exchanger temperature. Since the indoor fan 22 is rotated at a rotation speed a3, a large amount of air A3 of indoor air is blown into the room from the indoor unit 4. After time t3, although the indoor heat exchanger temperature C continues to rise slightly, the fluctuation range is reduced and becomes stable. After time t3, the rotation speed of the indoor fan 22 is approximately constant at the rotation speed a3 corresponding to the indoor heat exchanger temperature C.

次に、比較例として、図３を参照して、本発明と同様の条件下（室内温度Ｂ０且つ時間ｔ０に暖房運転を開始）で暖房を起動し、暖房起動時から熱交温度対応風量制御モードを実行した場合における暖房起動時からの風量、室内温度、熱交換器温度の時間経過を説明する。
先ず、空気調和機１の暖房運転が開始されると、制御装置８は、熱交温度対応風量制御モードを実行する。空気調和機１の暖房運転の開始時間は、図３において時間ｔ０により示される。時間ｔ０における室内の室内温度Ｂは、室内温度Ｂ０であり、室内熱交温度Ｃはほぼ室内温度と同じ温度となっている。制御装置８は、暖房の開始準備ができ次第、例えば室内熱交温度Ｃが所定温度Ｃ１まで上昇し次第、時間ｔ１から室内ファン２２を起動させ、熱交温度対応風量制御モードを実行する。 Next, as a comparative example, referring to FIG. 3, heating is started under the same conditions as in the present invention (indoor temperature B0 and heating operation is started at time t0), and air volume control corresponding to heat exchanger temperature is performed from the time of starting heating. The time course of the air volume, indoor temperature, and heat exchanger temperature from the time of starting heating when the mode is executed will be explained.
First, when the heating operation of the air conditioner 1 is started, the control device 8 executes the air volume control mode corresponding to the heat exchanger temperature. The start time of the heating operation of the air conditioner 1 is indicated by time t0 in FIG. 3. The indoor temperature B in the room at time t0 is the indoor temperature B0, and the indoor heat exchanger temperature C is almost the same as the indoor temperature. As soon as the control device 8 is ready to start heating, for example, as soon as the indoor heat exchanger temperature C rises to a predetermined temperature C1, the control device 8 starts the indoor fan 22 from time t1 and executes the heat exchanger temperature corresponding air volume control mode.

時間ｔ１以後、熱交温度対応風量制御モードにより、時間ｔ１以後、室内熱交温度Ｃが上昇するにつれ、室内ファン２２の回転数がａ１から段階的に上昇されている。これに伴って、室内温度Ｂも徐々に上昇している。室内熱交温度Ｃの上昇に対し段階的に室内ファン２２の回転数を上昇させているため、時間ｔ１からｔ２においては室内ファン２２の回転数がａ１となっている。
比較例において時間ｔ１から時間ｔ３までに室内機４から吹き出される風量の合計は、本実施形態において時間ｔ１から時間ｔ３までに室内機４から吹き出される風量Ａの合計に比べて少なくなっている。従って、比較例及び本実施形態とも時間ｔ３において、室内熱交温度Ｃが第３温度Ｃ３近傍となったとしても、比較例の室内温度Ｂ３’は、本実施形態における室内温度Ｂ３よりも低い値となっている。 After time t1, as the indoor heat exchanger temperature C rises, the rotation speed of the indoor fan 22 is gradually increased from a1 by the heat exchanger temperature corresponding air volume control mode. Along with this, the indoor temperature B is also gradually rising. Since the rotation speed of the indoor fan 22 is increased in stages as the indoor heat exchanger temperature C rises, the rotation speed of the indoor fan 22 is a1 from time t1 to t2.
In the comparative example, the total amount of air blown out from the indoor unit 4 from time t1 to time t3 is smaller than the total amount of air blown out from the indoor unit 4 A from time t1 to time t3 in the present embodiment. There is. Therefore, even if the indoor heat exchanger temperature C becomes near the third temperature C3 at time t3 in both the comparative example and the present embodiment, the indoor temperature B3' in the comparative example is a lower value than the indoor temperature B3 in the present embodiment. It becomes.

上述した本発明の一実施形態による空気調和機１によれば、制御装置８は、暖房起動時における室内温度が第１温度未満である場合には、小風量モードを実行し、次に、室内熱交温度Ｃが暖房起動時からの上昇過程において人の皮膚温度に基づいて設定された第２温度Ｃ２から第３温度Ｃ３までの範囲内にあるとき、大風量モードを実行する。これにより、暖房起動時に使用者の皮膚温度より低い風が使用者に当たることにより使用者の体感温度が下がり不快に感じる、いわゆるドラフト感を使用者に生じさせにくくしながらも、暖房起動時の目標室温への到達時間を短縮させることができる。 According to the air conditioner 1 according to the embodiment of the present invention described above, the control device 8 executes the small air volume mode when the indoor temperature at the time of starting the heating is lower than the first temperature, and then When the heat exchanger temperature C is within the range from the second temperature C2 to the third temperature C3, which is set based on the human skin temperature during the rising process from the time of starting the heating, the large air volume mode is executed. As a result, when the heating is turned on, wind that is lower than the user's skin temperature hits the user, which lowers the user's perceived temperature and makes the user feel uncomfortable. The time required to reach room temperature can be shortened.

さらに、本発明の一実施形態による空気調和機１によれば、制御装置８は、さらに、室内熱交温度Ｃが暖房起動時からの上昇過程において第２温度Ｃ２に到達して以後、室内熱交温度Ｃが第３温度Ｃ３に達するまでは、室内ファン２２の回転数を減少させないように制御する回転数非減少モードを備える。これにより、室内熱交温度Ｃが暖房起動時からの上昇過程において第２温度Ｃ２に到達して以後は、室内熱交温度Ｃが第２温度Ｃ２未満に低下したとしても、室内ファン２２により大風量の供給を維持し、暖房起動時の目標室温への到達時間をより短縮させることができる。 Furthermore, according to the air conditioner 1 according to the embodiment of the present invention, the control device 8 further controls the indoor heat exchanger temperature after the indoor heat exchanger temperature C reaches the second temperature C2 in the rising process from the time of starting the heating. A rotation speed non-reduction mode is provided in which the rotation speed of the indoor fan 22 is controlled not to be reduced until the exchange temperature C reaches the third temperature C3. As a result, after the indoor heat exchanger temperature C reaches the second temperature C2 during the rising process from the heating start, even if the indoor heat exchanger temperature C falls below the second temperature C2, the indoor fan 22 will increase the temperature. The supply of air volume can be maintained, and the time required to reach the target room temperature when heating is started can be further shortened.

さらに、本発明の一実施形態による空気調和機１によれば、室内温度Ｂが８℃～１２℃の範囲内に設定された第１温度未満である場合に、小風量モード、大風量モード等の実行により、暖房起動時に使用者の皮膚温度より低い風が使用者に当たることにより使用者の体感温度が下がり不快に感じる、いわゆるドラフト感を使用者に生じさせにくくしながらも、暖房起動時の目標室温への到達時間を短縮させることができる。 Furthermore, according to the air conditioner 1 according to the embodiment of the present invention, when the indoor temperature B is lower than the first temperature set within the range of 8° C. to 12° C., the small air volume mode, the large air volume mode, etc. As a result, when the heating is turned on, wind that is lower than the user's skin temperature hits the user, lowering the user's perceived temperature and making the user feel uncomfortable. The time required to reach the target room temperature can be shortened.

さらに、本発明の一実施形態による空気調和機１によれば、第２温度Ｃ２は、比較的低い室内温度Ｂに対応する人の皮膚温度に基づいて設定された、２８℃～３３℃の範囲内に設定されることができる。これにより、暖房起動時に使用者の皮膚温度より低い風が使用者に当たることにより使用者の体感温度が下がり不快に感じる、いわゆるドラフト感を使用者に生じさせにくくしながらも、暖房起動時の目標室温への到達時間を短縮させることができる。 Further, according to the air conditioner 1 according to the embodiment of the present invention, the second temperature C2 is in the range of 28°C to 33°C, which is set based on the human skin temperature corresponding to the relatively low indoor temperature B. can be set within. As a result, when the heating is turned on, wind that is lower than the user's skin temperature hits the user, which lowers the user's perceived temperature and makes the user feel uncomfortable. The time required to reach room temperature can be shortened.

さらに、本発明の一実施形態による空気調和機１によれば、第３温度Ｃ３は、比較的高い室内温度Ｂに対応する人の皮膚温度に基づいて設定された、３６℃～４０℃の範囲内に設定されることができる。これにより、制御装置８は、室内熱交温度Ｃが第３温度Ｃ３より大きくなっていない場合に、室内熱交温度Ｃが依然として使用者の想定の皮膚温度の上限を超えるほどには上昇しておらず、暖房起動時大風量モードにより室内温度Ｂの上昇をより促進させることができる状態であると判断できる。 Further, according to the air conditioner 1 according to the embodiment of the present invention, the third temperature C3 is in the range of 36°C to 40°C, which is set based on the human skin temperature corresponding to the relatively high indoor temperature B. can be set within. As a result, the control device 8 determines that when the indoor heat exchanger temperature C has not become higher than the third temperature C3, the indoor heat exchanger temperature C still rises to the extent that it exceeds the upper limit of the user's assumed skin temperature. Therefore, it can be determined that the state is such that the increase in indoor temperature B can be further promoted by the large air volume mode at heating startup.
