冷房運転時に室内機から送り出される冷風をなす空気は、室内機に取り込まれる空気よりも相対湿度が高くなる。 The air forming the cold air sent out from the indoor unit during the cooling operation has a higher relative humidity than the air taken into the indoor unit.

室内機の設置箇所と空気調和の対象の居室とが離れている場合、室内機と居室とを繋ぐ給気風路が長くなり、給気風路に滞留する相対湿度の高い空気は、自然には給気風路から排出されにくい。したがって、特許文献1に開示される発明においては、冷房運転の停止後に、給気風路に相対湿度が高い空気が滞留する状態が長時間継続し、給気風路に結露又はカビが発生しやすいという問題があった。 When the installation location of the indoor unit and the room subject to air conditioning are separated, the air supply air passage connecting the indoor unit and the living room becomes long, and the air with high relative humidity staying in the air supply air passage is naturally supplied. It is difficult to be discharged from the air passage. Therefore, in the invention disclosed in Patent Document 1, after the cooling operation is stopped, the air having a high relative humidity stays in the air supply air passage for a long time, and dew condensation or mold is likely to occur in the air supply air passage. There was a problem.

本発明は、上記に鑑みてなされたものであって、室内機から室内機の設置箇所とは異なる居室に通じる給気風路に結露又はカビが発生することを抑制した空気調和システムを得ることを目的とする。 The present invention has been made in view of the above, and is to obtain an air conditioning system that suppresses the generation of dew condensation or mold in the air supply air passage leading from the indoor unit to the living room different from the installation location of the indoor unit. The purpose.

上述した課題を解決し、目的を達成するために、本発明は、空気を加熱又は冷却する熱交換器と、熱交換器を通る空気を送り出す送風機と、熱交換器及び送風機を制御する運転制御部とを備えた室内機と、送風機によって熱交換器から送り出される空気を室内機の設置箇所とは異なる居室に通す給気風路とを備える。運転制御部は、熱交換器で空気を冷却する冷房運転を停止してから一定時間、送風機の運転を継続する。 In order to solve the above-mentioned problems and achieve the object, the present invention has a heat exchanger that heats or cools air, a blower that sends air through the heat exchanger, and an operation control that controls the heat exchanger and the blower. It is provided with an indoor unit equipped with a unit and an air supply air passage that allows air sent from a heat exchanger by a blower to pass through a living room different from the installation location of the indoor unit. The operation control unit continues the operation of the blower for a certain period of time after stopping the cooling operation of cooling the air with the heat exchanger.

本発明によれば、室内機から室内機の設置箇所とは異なる居室に通じる給気風路に給気風路に結露又はカビが発生することを抑制できるという効果を奏する。 According to the present invention, there is an effect that dew condensation or mold can be suppressed from forming in the air supply air passage leading from the indoor unit to the living room different from the installation location of the indoor unit.

It has an air passage 43, an air supply air passage 41 leading to an air outlet 32 provided on the floor of the living room 42, and an air duct 44 connecting the indoor unit 1 and the air supply air passage 41. The indoor unit 1 has a heat exchanger 12 connected to the heat pump units 2a and 2b at the refrigerant flow paths 21a and 21b. The heat exchanger 12 forms one refrigerating cycle with the heat pump unit 2a and the refrigerant flow path 21a, and forms another refrigerating cycle with the heat pump unit 2b and the refrigerant flow path 21b. That is, the heat exchanger 12 comprises two independent refrigeration cycles. The heat exchanger 12 exchanges heat between the air taken in from the living room 42 and the refrigerant circulating between the heat pump units 2a and 2b through the refrigerant flow paths 21a and 21b. Further, the indoor unit 1 has a blower 11 that sends the heat-exchanged air to the air supply air passage 41 through the blower duct 44.

給気風路41は、建物4の基礎45と、建材46とに挟まれた空間であり、室内機1から室内機1の設置箇所とは異なる居室42に通じる。給気風路41は、送風機11によって熱交換器12から送り出される空気を室内機1の設置箇所とは異なる居室42に通す。基礎45の表面には断熱層47が形成されている。また、建材46の表面には、撥水層48が形成されている。なお、建材46に非吸水性材料を適用し、撥水層48を省略した構成にしてもよい。建材46は、床材、柱材及び壁材を例示できる。図1において、給気風路41は、床下空間に設けられているが、天井裏の空間又は内壁と外壁との間の空間に設けられてもよい。また、給気風路41は、建物4内に設置された専用のダクトであってもよい。 The air supply air passage 41 is a space sandwiched between the foundation 45 of the building 4 and the building material 46, and leads from the indoor unit 1 to the living room 42 different from the installation location of the indoor unit 1. The air supply air passage 41 passes the air sent from the heat exchanger 12 by the blower 11 to the living room 42 different from the installation location of the indoor unit 1. A heat insulating layer 47 is formed on the surface of the foundation 45. Further, a water-repellent layer 48 is formed on the surface of the building material 46. A non-water-absorbent material may be applied to the building material 46, and the water-repellent layer 48 may be omitted. Examples of the building material 46 include floor materials, pillar materials, and wall materials. In FIG. 1, the air supply air passage 41 is provided in the underfloor space, but may be provided in the space behind the ceiling or in the space between the inner wall and the outer wall. Further, the air supply air passage 41 may be a dedicated duct installed in the building 4.

室内機1は、空気調和システム50を制御する運転制御部13を備えている。居室42に設置されたルームコントローラ31は、運転制御部13と通信可能である。 The indoor unit 1 includes an operation control unit 13 that controls the air conditioning system 50. The room controller 31 installed in the living room 42 can communicate with the operation control unit 13.

送風機11によって給気風路41に送られた熱交換後の空気は、建物4内の居室42の床に設けられた吹出口32から居室42に供給され、居室42が空気調和される。空気調和された居室42内の空気は、還気風路43を通って室内機1に還るため、建物4内で空気を循環させながら居室42の空気調和が行われる。 The air after heat exchange sent to the air supply air passage 41 by the blower 11 is supplied to the living room 42 from the air outlet 32 provided on the floor of the living room 42 in the building 4, and the living room 42 is air-conditioned. Since the air in the air-conditioned living room 42 returns to the indoor unit 1 through the return air passage 43, the air conditioning of the living room 42 is performed while circulating the air in the building 4.

図2は、実施の形態1に係る空気調和システムの機能ブロック図である。ルームコントローラ31は、居室42の室内温度を検知する室温検知部313と、文字列、画像及び音声といった視覚的又は聴覚的な方法でユーザに報知を行う報知部311と、ユーザの入力操作を受け付けるユーザインタフェースである操作部312とを有する。報知部311には、液晶表示装置及びスピーカを例示できる。操作部312には、タッチパネル及びキーボードを例示できる。 FIG. 2 is a functional block diagram of the air conditioning system according to the first embodiment. The room controller 31 receives a room temperature detection unit 313 that detects the room temperature of the living room 42, a notification unit 311 that notifies the user by a visual or auditory method such as a character string, an image, and a voice, and a user input operation. It has an operation unit 312 which is a user interface. A liquid crystal display device and a speaker can be exemplified in the notification unit 311. A touch panel and a keyboard can be exemplified as the operation unit 312.

運転制御部13は、送風機11及び熱交換器12に運転指示を送って空調運転を制御する統合制御部131と、送風機11の運転時間を計測する送風機運転時間計測部132と、冷房運転を停止してから送風機11の運転を継続する時間を記憶する送風機運転継続時間記憶部133と、熱交換器12の運転時間を計測する熱交換器運転時間計測部134と、除湿運転を行うか否かを判定する除湿運転判定部135と、送風機11の運転を終了するか否かを判定する送風機継続運転終了判定部136とを有する。統合制御部131には、送風機運転時間計測部132から送風機11の運転時間の情報が送られる。また、統合制御部131には、熱交換器運転時間計測部134から、熱交換器12が冷房運転、暖房運転又は除湿運転を行った時間の情報が送られる。統合制御部131は、送風機運転時間計測部132及び熱交換器運転時間計測部134から受信した情報に基づいて空調運転を制御する。 The operation control unit 13 stops the cooling operation, the integrated control unit 131 that sends an operation instruction to the blower 11 and the heat exchanger 12 to control the air conditioning operation, the blower operation time measurement unit 132 that measures the operation time of the blower 11. Whether or not to perform dehumidification operation is performed by the blower operation continuation time storage unit 133 that stores the time for continuing the operation of the blower 11 and the heat exchanger operation time measurement unit 134 that measures the operation time of the heat exchanger 12. It has a dehumidifying operation determination unit 135 for determining, and a blower continuous operation end determination unit 136 for determining whether or not to terminate the operation of the blower 11. Information on the operating time of the blower 11 is sent from the blower operating time measuring unit 132 to the integrated control unit 131. Further, information on the time when the heat exchanger 12 has performed the cooling operation, the heating operation, or the dehumidifying operation is sent to the integrated control unit 131 from the heat exchanger operation time measuring unit 134. The integrated control unit 131 controls the air conditioning operation based on the information received from the blower operation time measurement unit 132 and the heat exchanger operation time measurement unit 134.

ルームコントローラ31は、統合制御部131と通信可能に接続され、相互に情報の送受信が行われる。具体例をあげると、ルームコントローラ31の操作部312で受け付けた操作の情報及び室温検知部313で検知された室温の情報が統合制御部131に送られる。また、統合制御部131が決定した制御内容がルームコントローラ31に送られ、報知部311からユーザに報知される。 The room controller 31 is communicably connected to the integrated control unit 131, and information is transmitted and received to and from each other. To give a specific example, information on the operation received by the operation unit 312 of the room controller 31 and information on the room temperature detected by the room temperature detection unit 313 are sent to the integrated control unit 131. Further, the control content determined by the integrated control unit 131 is sent to the room controller 31, and the notification unit 311 notifies the user.

送風機運転継続時間記憶部133には、冷房運転中に熱交換器12を一定時間よりも長く運転したか否かの判定を冷房運転停止後に行うのに用いる第1の判定時間と、冷房運転停止後に送風機11を単独で一定時間運転したか否かの判定を行うのに用いる送風機運転継続時間である第2の判定時間と、冷房運転停止後に熱交換器12による除湿運転とともに送風機11を一定時間運転したか否かの判定を行うのに用いる送風機運転継続時間である第3の判定時間とが記憶される。 The blower operation duration storage unit 133 has a first determination time used to determine whether or not the heat exchanger 12 has been operated for longer than a certain period of time during the cooling operation, and a cooling operation stop. The second determination time, which is the duration of the blower operation used to later determine whether or not the blower 11 has been operated independently for a certain period of time, and the dehumidifying operation by the heat exchanger 12 after the cooling operation is stopped, the blower 11 is operated for a certain period of time. The third determination time, which is the operation duration of the blower used to determine whether or not the air conditioner has been operated, is stored.

除湿運転判定部135には、熱交換器12よりも下流側の空気の湿度を計測する空気湿度検知部14と、熱交換器12よりも上流側の空気の温度を計測し、熱交換器12よりも下流側の空気の湿度を推定する熱交換前空気温度検知部15と、熱交換器12よりも下流側の空気の温度を計測し、熱交換器12よりも下流側の空気の湿度を推定する熱交換後空気温度検知部16との少なくともいずれかが接続される。熱交換前空気温度検知部15及び熱交換後空気温度検知部16は、温度の測定結果に基づいて、熱交換器12よりも下流側の空気の湿度を算出してもよいし、温度測定結果と熱交換器12よりも下流側の空気の湿度とが対応付けられたテーブルを参照して、熱交換器12よりも下流側の空気の湿度を推定してもよい。また、除湿運転判定部135には、冷房運転後の除湿運転が必要であるか否かを判定するのに用いられる除湿運転の第1の判定条件と、冷房運転後の除湿運転が必要無くなったか否かを判定するのに用いられる除湿運転の第2の判定条件とが記憶されている。除湿運転の第1の判定条件は、熱交換器12よりも下流側の空気の湿度が第1の湿度よりも高いことであり、除湿運転の第2の判定条件は、熱交換器12よりも下流側の空気の湿度が第2の湿度よりも低いことである。したがって、第1の湿度は、冷房運転後の除湿運転が必要であるか否かの判定での閾値であり、第2の湿度は、冷房運転後の除湿運転が必要無くなったか否かの判定での閾値である。なお、第2の湿度は、第1の湿度以下である。 The dehumidifying operation determination unit 135 includes an air humidity detection unit 14 that measures the humidity of the air downstream of the heat exchanger 12, and a heat exchanger 12 that measures the temperature of the air upstream of the heat exchanger 12. The pre-heat exchange air temperature detector 15 that estimates the humidity of the air downstream of the heat exchanger 12 measures the temperature of the air downstream of the heat exchanger 12, and determines the humidity of the air downstream of the heat exchanger 12. At least one of the estimated heat exchange post-heat exchange air temperature detection unit 16 is connected. The pre-heat exchange air temperature detection unit 15 and the post-heat exchange air temperature detection unit 16 may calculate the humidity of the air downstream of the heat exchanger 12 based on the temperature measurement results, or the temperature measurement results. And the humidity of the air downstream of the heat exchanger 12 may be estimated with reference to the table associated with the humidity of the air downstream of the heat exchanger 12. Further, the dehumidifying operation determination unit 135 has the first determination condition of the dehumidifying operation used for determining whether or not the dehumidifying operation after the cooling operation is necessary, and whether the dehumidifying operation after the cooling operation is no longer necessary. The second determination condition of the dehumidifying operation used to determine whether or not it is stored is stored. The first determination condition of the dehumidification operation is that the humidity of the air downstream of the heat exchanger 12 is higher than the first humidity, and the second determination condition of the dehumidification operation is that the humidity of the air downstream of the heat exchanger 12 is higher than that of the heat exchanger 12. The humidity of the air on the downstream side is lower than that of the second humidity. Therefore, the first humidity is a threshold value in determining whether or not the dehumidifying operation after the cooling operation is necessary, and the second humidity is the threshold value in determining whether or not the dehumidifying operation after the cooling operation is necessary. Is the threshold value of. The second humidity is equal to or lower than the first humidity.

空気湿度検知部14は、給気風路41内に設置され、給気風路41内の空気の湿度の情報を除湿運転判定部135に送信する。空気湿度検知部14は、ルームコントローラ31又は室内機1に内蔵され、居室42又は還気風路43内の空気の湿度を計測し、熱交換器12よりも下流側の空気の湿度を推定してもよい。空気湿度検知部14から受信した情報に基づいて除湿運転判定部135が判定を行う場合、除湿運転判定部135は、給気風路41内の空気の湿度が第1の湿度よりも高い場合に除湿運転の第1の判定条件を満たすと判定し、第2の湿度よりも低くなった場合に除湿運転の第2の判定条件を満たすと判定する。 The air humidity detection unit 14 is installed in the air supply air passage 41, and transmits information on the humidity of the air in the air supply air passage 41 to the dehumidifying operation determination unit 135. The air humidity detection unit 14 is built in the room controller 31 or the indoor unit 1, measures the humidity of the air in the living room 42 or the return air passage 43, and estimates the humidity of the air downstream of the heat exchanger 12. May be good. When the dehumidifying operation determination unit 135 makes a determination based on the information received from the air humidity detection unit 14, the dehumidification operation determination unit 135 dehumidifies when the humidity of the air in the air supply air passage 41 is higher than the first humidity. It is determined that the first determination condition of the operation is satisfied, and when the humidity becomes lower than the second humidity, it is determined that the second determination condition of the dehumidification operation is satisfied.

熱交換前空気温度検知部15が推定する熱交換器12よりも下流側の湿度は、熱交換前の空気の温度が第1の温度よりも高い場合には、第1の湿度よりも高い値となり、第2の温度よりも低い場合には、第2の湿度よりも低い値となる。したがって、熱交換前空気温度検知部15が推定した熱交換器12よりも下流側の空気の湿度に基づいて除湿運転判定部135が判定を行う場合、除湿運転判定部135は、熱交換器12よりも上流側の空気の温度が第1の温度よりも高い場合に除湿運転の第1の判定条件を満たすと判定し、第2の温度よりも低くなった場合に除湿運転の第2の判定条件を満たすと判定する。すなわち、除湿運転判定部135に記憶される除湿運転の第1の判定条件は、第1の温度となり、除湿運転の第2の判定条件は、第2の温度となる。したがって、第1の温度は、冷房運転後の除湿運転が必要であるか否かの判定での閾値であり、第2の温度は、冷房運転後の除湿運転が必要無くなったか否かの判定での閾値である。熱交換前空気温度検知部15は、室内機1内で熱交換器12よりも上流側に設けられる。なお、ルームコントローラ31の室温検知部313が熱交換前空気温度検知部15を兼ねても良い。 The humidity on the downstream side of the heat exchanger 12 estimated by the air temperature detection unit 15 before heat exchange is higher than the first humidity when the temperature of the air before heat exchange is higher than the first temperature. When the temperature is lower than the second temperature, the value is lower than the second humidity. Therefore, when the dehumidifying operation determination unit 135 makes a determination based on the humidity of the air downstream of the heat exchanger 12 estimated by the pre-heat exchange air temperature detection unit 15, the dehumidification operation determination unit 135 uses the heat exchanger 12. When the temperature of the air on the upstream side is higher than the first temperature, it is determined that the first determination condition of the dehumidifying operation is satisfied, and when the temperature is lower than the second temperature, the second determination of the dehumidifying operation is performed. It is determined that the condition is satisfied. That is, the first determination condition of the dehumidification operation stored in the dehumidification operation determination unit 135 is the first temperature, and the second determination condition of the dehumidification operation is the second temperature. Therefore, the first temperature is a threshold value for determining whether or not the dehumidifying operation after the cooling operation is necessary, and the second temperature is the threshold value for determining whether or not the dehumidifying operation after the cooling operation is necessary. Is the threshold value of. The pre-heat exchange air temperature detecting unit 15 is provided in the indoor unit 1 on the upstream side of the heat exchanger 12. The room temperature detection unit 313 of the room controller 31 may also serve as the air temperature detection unit 15 before heat exchange.

熱交換後空気温度検知部16が推定する熱交換器12よりも下流側の空気の湿度は、熱交換器12よりも下流側の空気の温度が第3の温度よりも低い場合には、第1の湿度よりも高い値となり、第4の温度よりも高い場合には、第2の湿度よりも低い値となる。したがって、熱交換後空気温度検知部16が推定する熱交換器12よりも下流側の空気の湿度に基づいて除湿運転判定部135が判定を行う場合、除湿運転判定部135は、熱交換器12よりも下流側の空気の温度が第3の温度よりも低い場合に除湿運転の第1の判定条件を満たすと判定し、第4の温度よりも高くなった場合に除湿運転の第2の判定条件を満たすと判定する。すなわち、除湿運転判定部135に記憶される除湿運転の第1の判定条件は、第3の温度となり、除湿運転の第2の判定条件は、第4の温度となる。したがって、第3の温度は、冷房運転後の除湿運転が必要であるか否かの判定での閾値であり、第4の温度は、冷房運転後の除湿運転が必要無くなったか否かの判定での閾値である。 The humidity of the air downstream of the heat exchanger 12 estimated by the air temperature detector 16 after heat exchange is the first when the temperature of the air downstream of the heat exchanger 12 is lower than the third temperature. The value is higher than the humidity of 1, and when the temperature is higher than the fourth temperature, the value is lower than the second humidity. Therefore, when the dehumidifying operation determination unit 135 makes a determination based on the humidity of the air downstream of the heat exchanger 12 estimated by the air temperature detection unit 16 after heat exchange, the dehumidification operation determination unit 135 uses the heat exchanger 12. When the temperature of the air on the downstream side is lower than the third temperature, it is determined that the first determination condition of the dehumidifying operation is satisfied, and when the temperature is higher than the fourth temperature, the second determination of the dehumidifying operation is performed. It is determined that the condition is satisfied. That is, the first determination condition of the dehumidification operation stored in the dehumidification operation determination unit 135 is the third temperature, and the second determination condition of the dehumidification operation is the fourth temperature. Therefore, the third temperature is a threshold value for determining whether or not the dehumidifying operation after the cooling operation is necessary, and the fourth temperature is the threshold value for determining whether or not the dehumidifying operation after the cooling operation is necessary. Is the threshold value of.

なお、除湿運転判定部135は、除湿運転の第1の判定条件を満たすか否かの判定と、除湿運転の第2の判定条件を満たすか否かの判定とに、空気湿度検知部14が計測した熱交換器12よりも下流側の空気の湿度、熱交換前空気温度検知部15が推定した熱交換器12よりも下流側の空気の湿度及び熱交換後空気温度検知部16が推定した熱交換器12よりも下流側の空気のうち異なるものを用いても良い。 In the dehumidifying operation determination unit 135, the air humidity detecting unit 14 determines whether or not the first determination condition of the dehumidifying operation is satisfied and whether or not the second determination condition of the dehumidifying operation is satisfied. The measured air humidity downstream of the heat exchanger 12, the air humidity downstream of the heat exchanger 12 estimated by the pre-heat exchange air temperature detector 15, and the post-heat exchange air temperature detector 16 estimated. A different type of air downstream of the heat exchanger 12 may be used.

熱交換器12よりも下流側の空気の相対湿度が90%以上であることを除湿運転の第1の判定条件とし、熱交換器12よりも下流側の空気の相対湿度が70%未満であることを除湿運転の第2の判定条件と設定することで、給気風路41内が高湿度状態となることを抑制できる。 The first determination condition of the dehumidifying operation is that the relative humidity of the air downstream of the heat exchanger 12 is 90% or more, and the relative humidity of the air downstream of the heat exchanger 12 is less than 70%. By setting this as the second determination condition for the dehumidifying operation, it is possible to prevent the inside of the air supply air passage 41 from becoming in a high humidity state.

除湿運転を行う際には、2台のヒートポンプユニット2a,2bの一方で暖房運転を行い、他方で冷房運転を行うことで、熱交換器12で空気を冷やして除湿した後に再度空気を加熱する再熱除湿運転を行い、居室42の温度が低下することを抑制できる。 When performing the dehumidifying operation, the two heat pump units 2a and 2b are heated on one side and cooled on the other side, so that the air is cooled and dehumidified by the heat exchanger 12 and then heated again. The reheat dehumidification operation can be performed to prevent the temperature of the living room 42 from dropping.

図3は、実施の形態1に係る空気調和システムの動作の流れを示すフローチャートである。ステップS1において、統合制御部131が冷房運転を停止させると、送風機運転時間計測部132は、送風機11の運転時間をリセットする。ステップS2において、統合制御部131は、熱交換器運転時間計測部134から受信した熱交換器12の運転時間の情報に基づいて、冷房運転中の熱交換器12の運転時間が第1の判定時間よりも長かったか否かを判断する。冷房運転中の熱交換器12の運転時間が第1の判定時間よりも長ければ、ステップS2でYesとなりステップS3に進む。冷房運転中の熱交換器12の運転時間が第1の判定時間以下であれば、ステップS2でNoとなり、ステップS9に進む。 FIG. 3 is a flowchart showing the flow of operation of the air conditioning system according to the first embodiment. In step S1, when the integrated control unit 131 stops the cooling operation, the blower operation time measuring unit 132 resets the operation time of the blower 11. In step S2, the integrated control unit 131 first determines the operating time of the heat exchanger 12 during the cooling operation based on the information on the operating time of the heat exchanger 12 received from the heat exchanger operating time measuring unit 134. Determine if it was longer than the time. If the operating time of the heat exchanger 12 during the cooling operation is longer than the first determination time, Yes in step S2 and the process proceeds to step S3. If the operating time of the heat exchanger 12 during the cooling operation is equal to or less than the first determination time, the result is No in step S2, and the process proceeds to step S9.

If the first determination condition of the dehumidifying operation is satisfied, the result is Yes in step S3, and the process proceeds to step S6. If the first determination condition of the dehumidifying operation is not satisfied, the result is No in step S3, and the process proceeds to step S4.

ステップS4において、統合制御部131は、送風機11の運転を継続する。ステップS5において、統合制御部131は、送風機運転時間計測部132から受信した送風機11の運転時間の情報に基づいて、冷房運転停止後の送風機11の運転時間が第2の判定時間よりも長いか否かを判断する。冷房運転停止後の送風機11の運転時間が第2の判定時間よりも長ければ、ステップS5でYesとなり、ステップS9に進む。冷房運転停止後の送風機11の運転時間が第2の判定時間以下であれば、ステップS5でNoとなり、ステップS4に戻る。 In step S4, the integrated control unit 131 continues the operation of the blower 11. In step S5, is the integrated control unit 131 longer than the second determination time after the cooling operation is stopped, based on the information on the operation time of the blower 11 received from the blower operation time measurement unit 132? Judge whether or not. If the operating time of the blower 11 after the cooling operation is stopped is longer than the second determination time, the result is Yes in step S5, and the process proceeds to step S9. If the operation time of the blower 11 after the cooling operation is stopped is equal to or less than the second determination time, the result is No in step S5, and the process returns to step S4.

ステップS6において、統合制御部131は、熱交換器12による除湿を開始するとともに、送風機11の運転を継続し、除湿運転を行う。ステップS7において、除湿運転判定部135は、除湿運転の第2の判定条件を満たし、除湿運転が不要になったか否かを判定する。除湿運転の第2の判定条件を満たしていれば、ステップS7でYesとなり、ステップS9に進む。除湿運転の第2の判定条件を満たしていなければ、ステップS7でNoとなり、ステップS8に進む。 In step S6, the integrated control unit 131 starts dehumidification by the heat exchanger 12 and continues the operation of the blower 11 to perform the dehumidification operation. In step S7, the dehumidifying operation determination unit 135 satisfies the second determination condition of the dehumidifying operation and determines whether or not the dehumidifying operation is no longer necessary. If the second determination condition of the dehumidifying operation is satisfied, the result is Yes in step S7, and the process proceeds to step S9. If the second determination condition of the dehumidifying operation is not satisfied, the result is No in step S7, and the process proceeds to step S8.

ステップS8において、統合制御部131は、送風機運転時間計測部132から受信した送風機11の運転時間の情報に基づいて、冷房運転停止後の送風機11の運転時間が第3の判定時間よりも長いか否かを判断する。冷房運転停止後の送風機11の運転時間が第3の判定時間よりも長ければ、ステップS8でYesとなり、ステップS9に進む。冷房運転停止後の送風機11の運転時間が第3の判定時間以下であれば、ステップS8でNoとなり、ステップS7に戻る。 In step S8, is the integrated control unit 131 longer than the third determination time after the cooling operation is stopped, based on the information on the operation time of the blower 11 received from the blower operation time measurement unit 132? Judge whether or not. If the operating time of the blower 11 after the cooling operation is stopped is longer than the third determination time, the result is Yes in step S8, and the process proceeds to step S9. If the operation time of the blower 11 after the cooling operation is stopped is equal to or less than the third determination time, the result is No in step S8, and the process returns to step S7.

ステップS9において、統合制御部131は、送風機11及び熱交換器12の運転を停止させる。ステップS10において、送風機運転時間計測部132は、送風機11の運転時間をリセットする。また、熱交換器運転時間計測部134は、熱交換器12の運転時間をリセットする。 In step S9, the integrated control unit 131 stops the operation of the blower 11 and the heat exchanger 12. In step S10, the blower operation time measuring unit 132 resets the operation time of the blower 11. Further, the heat exchanger operating time measuring unit 134 resets the operating time of the heat exchanger 12.

以上のように、実施の形態1に係る空気調和システム50は、冷房運転終了後に送風機11の運転を継続し、給気風路41内が高湿度になっている場合は熱交換器12による除湿運転を併用するため、冷房運転終了後に給気風路41内が高湿度となっている状態が解消されるまでの時間を短縮できる。したがって、実施の形態1に係る空気調和システム50は、結露の発生を防止し、カビの発生を抑制できる。また、実施の形態1に係る空気調和システム50は、給気風路41内が高湿度になっている時だけ除湿運転を行うことで、消費電力の低減を図ることができる。また、実施の形態1に係る空気調和システム50は、給気風路41内が高湿度となっている状態が解消されたら送風機11を停止させるため、消費電力の低減を図ることができる。 As described above, the air conditioning system 50 according to the first embodiment continues the operation of the blower 11 after the cooling operation is completed, and when the inside of the air supply air passage 41 is in high humidity, the dehumidification operation by the heat exchanger 12 is performed. Therefore, it is possible to shorten the time until the state of high humidity in the air supply air passage 41 is resolved after the cooling operation is completed. Therefore, the air conditioning system 50 according to the first embodiment can prevent the generation of dew condensation and suppress the generation of mold. Further, the air conditioning system 50 according to the first embodiment can reduce the power consumption by performing the dehumidifying operation only when the inside of the air supply air passage 41 is in high humidity. Further, in the air conditioning system 50 according to the first embodiment, the blower 11 is stopped when the state of high humidity in the air supply air passage 41 is resolved, so that the power consumption can be reduced.

なお、送風機運転継続時間記憶部133は、冷房運転を行った時間の長さと正の相関関係を有する第2の判定時間及び第3の判定時間を複数記憶してもよい。第2の判定時間及び第3の判定時間を送風機運転継続時間記憶部133に複数記憶することにより、送風機11の運転を継続する時間を、冷房運転を行った長さに合わせて変えることができ、消費電力の低減を図ることができる。また、実施の形態1に係る空気調和システム50は、建材46の表面に撥水層48を備えるため、建材46の劣化を抑え、給気風路41にカビが発生することを抑制できる。 The blower operation duration storage unit 133 may store a plurality of second determination time and third determination time having a positive correlation with the length of time during which the cooling operation is performed. By storing a plurality of the second determination time and the third determination time in the blower operation continuation time storage unit 133, the time for continuing the operation of the blower 11 can be changed according to the length of the cooling operation. , Power consumption can be reduced. Further, since the air conditioning system 50 according to the first embodiment is provided with the water-repellent layer 48 on the surface of the building material 46, deterioration of the building material 46 can be suppressed and mold can be suppressed from being generated in the air supply air passage 41.

FIG. 4 is a functional block diagram of the operation control unit of the air conditioning system according to the second embodiment of the present invention. The operation control unit 13 of the air conditioning system 50 according to the second embodiment does not include the blower operation time measurement unit 132, the blower operation continuation time storage unit 133, the dehumidification operation determination unit 135, and the blower continuous operation end determination unit 136. Further, the operation control unit 13 of the air conditioning system 50 according to the second embodiment has a maintenance determination unit 137 for determining whether or not maintenance is necessary. Other than this, it is the same as the operation control unit 13 of the air conditioning system 50 according to the first embodiment.

図5は、実施の形態2に係る空気調和システムの動作の流れを示すフローチャートである。ステップS11において、統合制御部131は冷房運転を停止させる。ステップS12において、メンテナンス判定部137は、統合制御部131に記憶されている熱交換器12の冷房運転の積算時間が、時間の閾値を超えているか否かを判定する。熱交換器12の冷房運転の積算時間が、時間の閾値を超えていれば、ステップS12でYesとなりステップS13に進む。熱交換器12の冷房運転の積算時間が、時間の閾値を超えていなければ、ステップS12でNoとなりステップS14に進む。 FIG. 5 is a flowchart showing the operation flow of the air conditioning system according to the second embodiment. In step S11, the integrated control unit 131 stops the cooling operation. In step S12, the maintenance determination unit 137 determines whether or not the integrated time of the cooling operation of the heat exchanger 12 stored in the integrated control unit 131 exceeds the time threshold value. If the integrated time of the cooling operation of the heat exchanger 12 exceeds the time threshold, Yes in step S12 and the process proceeds to step S13. If the integrated time of the cooling operation of the heat exchanger 12 does not exceed the time threshold value, No in step S12 and the process proceeds to step S14.

ステップS13において、統合制御部131は、メンテナンスが必要であることを示す情報を報知部311から出力し、ユーザに報知する。報知部311によってユーザに報知される情報は、給気風路41の点検又は清掃を促すものであり、ディスプレイに文章を表示する方法、音声により通知する方法、及び特定のエラーコードを表示する方法を例示できる。また、住宅の管理会社、住宅のメンテナンス業者又は空気調和システム50のメンテナンス業者と契約し、管理会社又はメンテナンス業者へ直接メンテナンス情報を報知し、管理会社又はメンテナンス業者からユーザへメンテナンス時期のアナウンスを行うようにしてもよい。 In step S13, the integrated control unit 131 outputs information indicating that maintenance is necessary from the notification unit 311 and notifies the user. The information notified to the user by the notification unit 311 prompts the inspection or cleaning of the air supply air passage 41, and a method of displaying a sentence on the display, a method of notifying by voice, and a method of displaying a specific error code. It can be exemplified. In addition, a contract is made with a housing management company, a housing maintenance company, or a maintenance company for an air conditioning system 50, maintenance information is directly notified to the management company or maintenance company, and the management company or maintenance company announces the maintenance time to the user. You may do so.

ステップS14において、統合制御部131は、熱交換器12の冷房運転の積算時間を更新して記憶する。 In step S14, the integrated control unit 131 updates and stores the integrated time of the cooling operation of the heat exchanger 12.

ステップS15において、統合制御部131は、送風機11及び熱交換器12の運転を停止させる。 In step S15, the integrated control unit 131 stops the operation of the blower 11 and the heat exchanger 12.

管理会社、メンテナンス業者又はユーザにより適切な点検及び清掃を行った後に、冷房運転時間の積算時間をリセットすることで、引き続き適切なタイミングでユーザにメンテナンス時期を報知することができる。定期的にメンテナンス時期を報知するにあたっては、メンテナンス時期を判定する冷房運転の積算時間は、毎回同じ積算時間を使用してもよいし、メンテナンス情報の報知回数が増加するにつれて次回メンテナンスまでの積算時間を短くしてもよい。 By resetting the integrated cooling operation time after performing appropriate inspections and cleaning by the management company, maintenance company, or user, it is possible to continuously notify the user of the maintenance time at an appropriate timing. In periodically notifying the maintenance time, the same integrated time may be used for the integrated time of the cooling operation for determining the maintenance time each time, or as the number of times of notification of maintenance information increases, the integrated time until the next maintenance. May be shortened.

上記の説明では、熱交換器12の冷房運転時間の積算時間が閾値を超えるか否かに基づいてメンテナンスの要否を判定したが、実施の形態1と同様に熱交換後空気温度検知部16を備えた構成とし、冷房運転中に熱交換後空気温度検知部16にて検知した熱交換器12よりも下流側の空気の温度が、閾値を超えた時間を積算し、積算時間がメンテナンス判定基準を超えたときにメンテナンス情報を報知してもよい。また、実施の形態1と同様に空気湿度検知部14を備えた構成とし、冷房運転中に空気湿度検知部14にて熱交換器12よりも下流側の空気の湿度を検知し、熱交換器12よりも下流側の空気の湿度が閾値を超えた時間を積算し、積算時間がメンテナンス判定基準を超えたときにメンテナンス情報を報知してもよい。 In the above description, the necessity of maintenance is determined based on whether or not the integrated cooling operation time of the heat exchanger 12 exceeds the threshold value, but the air temperature detection unit 16 after heat exchange is the same as in the first embodiment. The time when the air temperature on the downstream side of the heat exchanger 12 detected by the air temperature detection unit 16 after heat exchange during the cooling operation exceeds the threshold value is integrated, and the integrated time is determined for maintenance. Maintenance information may be notified when the standard is exceeded.
