Description

本発明は、空気処理システムの制御方法及び空気処理システムに関する。 The present invention relates to a method of controlling an air treatment system and an air treatment system.

生活水準の向上に伴い、人々は、生活しているオフィス・住宅環境による健康問題に対してもますます重視している。 With the improvement of living standards, people are paying more and more attention to health problems caused by the office and residential environments in which they live.

例えば、近年、建材や家具等から放出されるホルムアルデヒドによる問題がますます、重視されており、ホルムアルデヒドを除去する機能が付けられた浄化器や空調装置等の各種の空気処理設備に対する需要も高まっていく。 For example, in recent years, the problem of formaldehyde emitted from building materials and furniture has become more and more important, and demand has also increased for various air treatment equipment such as purifiers and air conditioners that are equipped with functions to remove formaldehyde. go.

ホルムアルデヒドと同様に、建材等の表面に付着したカビが産生するカビ毒素も、人々、特に子供の健康に影響を与えるものである。しかしながら、現在市販されている抗菌・防カビ機能を有する空気処理設備はあまり見られない。 Similar to formaldehyde, mycotoxins produced by mold attached to the surfaces of building materials and the like also affect the health of people, especially children. However, there are not many air treatment equipment with antibacterial and antifungal functions currently available on the market.

本発明は、上記問題に鑑みてなされたものであり、その目的は、カビの発生の防止に寄与する、空気処理システムの制御方法及び空気処理システムを提供することである。 The present invention has been made in view of the above problems, and its purpose is to provide a control method for an air treatment system and an air treatment system that contribute to preventing the growth of mold.

上記目的を達成するために、本発明は、空気処理システムの制御方法であって、前記空気処理システムによって調節される対象空間の相対湿度が第１の目標相対湿度よりも大きい場合、前記空気処理システムにカビ防止運転を実行させ、前記カビ防止運転中に、室内温度が第１の室内温度よりも大きい場合、前記空気処理システムに冷房運転及び／又は除湿運転を実行させ、前記室内温度が第２の室内温度よりも小さい場合、前記空気処理システムに暖房運転を実行させ、前記第２の室内温度が前記第１の室内温度よりも小さい空気処理システムの制御方法を提供する。 To achieve the above object, the present invention provides a method for controlling an air treatment system, in which when the relative humidity of a target space adjusted by the air treatment system is greater than a first target relative humidity, the air treatment The system is caused to perform a mold prevention operation, and when the indoor temperature is higher than a first indoor temperature during the mold prevention operation, the air treatment system is caused to perform a cooling operation and/or a dehumidification operation, and when the indoor temperature is higher than the first indoor temperature. If the second indoor temperature is lower than the first indoor temperature, the air processing system is caused to perform a heating operation, and the second indoor temperature is lower than the first indoor temperature.

ここでいう「除湿運転」は、除湿器による除湿運転だけでなく、空調装置の室内機が弱冷房の方式によって行う除湿運転を含んでもよく、さらに、空調装置の室内機が２以上の熱交換器を備えた場合、少なくとも１つの熱交換器が冷房するが、少なくとも１つの熱交換器が暖房することによって実現された再熱除湿運転を含んでもよい。しかも、第１の目標相対湿度は、実験などによって予め設定されたものであり、かつ、室内の温度に応じて調節されるように設置されてもよい。例えば、室内の温度が高い場合、ある値となるが、室内の温度が低い場合、別の値となる。また、第１の室内温度と第２の室内温度は必要に応じて予め設定されたものであり、例えば、第１の室内温度を２２℃に、第２の室内温度を１８℃に設定してもよい。 The "dehumidifying operation" here may include not only dehumidifying operation using a dehumidifier, but also dehumidifying operation performed by the indoor unit of the air conditioner using a weak cooling method, and furthermore, the indoor unit of the air conditioner may include two or more heat exchangers. When equipped with a heat exchanger, at least one heat exchanger provides cooling, but it may also include a reheat dehumidification operation realized by at least one heat exchanger providing heating. Moreover, the first target relative humidity may be set in advance through experiments or the like, and may be installed so as to be adjusted according to the indoor temperature. For example, if the indoor temperature is high, it will take a certain value, but if the indoor temperature is low, it will take a different value. Further, the first indoor temperature and the second indoor temperature are set in advance as necessary. For example, the first indoor temperature is set to 22°C and the second indoor temperature is set to 18°C. Good too.

本発明における空気処理システムの制御方法によれば、空気処理システムによって調節される室内空間の相対湿度が第１の目標相対湿度よりも大きい場合、空気処理システムにカビ防止運転を実行させ、カビ防止運転中に、室内温度が第１の室内温度よりも大きい場合、空気処理システムに冷房運転及び／又は除湿運転を実行させ、室内温度が第１の室内温度より小さい第２の室内温度よりも小さい場合、空気処理システムに暖房運転を実行させるため、室内の湿度を適切なモードで調節することができ、カビ防止運転中にモードに対する不適切な選択に起因して、空調装置が長時間に亘ってサーモオフ（ｔｈｅｒｍｏ－ｏｆｆ）状態にあり、エネルギーの浪費となり、かつ、予期通りにカビ防止効果を実現させることができないことを回避した。 According to the method for controlling an air treatment system of the present invention, when the relative humidity of the indoor space regulated by the air treatment system is greater than the first target relative humidity, the air treatment system is caused to perform mold prevention operation, and mold prevention is performed. During operation, if the indoor temperature is greater than the first indoor temperature, the air treatment system is caused to perform the cooling operation and/or the dehumidification operation, and the indoor temperature is smaller than the second indoor temperature, which is smaller than the first indoor temperature. In case, the room humidity can be adjusted in the appropriate mode to force the air treatment system to carry out the heating operation, and due to an inappropriate selection of the mode during the anti-mold operation, the air conditioner is operated for a long time. This avoids the situation where the mold is in a thermo-off state, which wastes energy and prevents mold prevention from being achieved as expected.

また、本発明における空気処理システムの制御方法では、好ましくは、前記カビ防止運転中に、前記室内温度が前記第１の室内温度よりも大きく、かつ、室外温度が第１の室外温度よりも大きい場合、前記空気処理システムに冷房運転及び／又は除湿運転を実行させ、前記室内温度が前記第２の室内温度よりも小さく、かつ、前記室外温度が第２の室外温度よりも小さい場合、前記空気処理システムに暖房運転を実行させ、前記第２の室外温度が前記第１の室外温度よりも小さい。 Further, in the method for controlling an air treatment system according to the present invention, preferably, during the mold prevention operation, the indoor temperature is higher than the first indoor temperature, and the outdoor temperature is higher than the first outdoor temperature. If the air processing system is caused to perform a cooling operation and/or a dehumidification operation, and the indoor temperature is lower than the second indoor temperature, and the outdoor temperature is lower than the second outdoor temperature, the air The processing system is caused to perform a heating operation, and the second outdoor temperature is lower than the first outdoor temperature.

ここで、第１の室内温度と第２の室内温度は必要に応じて予め設定されたものであり、例えば、第１の室内温度を２０℃に、第２の室内温度を１６℃に設定してもよい。 Here, the first indoor temperature and the second indoor temperature are set in advance as necessary. For example, the first indoor temperature is set to 20°C and the second indoor temperature is set to 16°C. It's okay.

By adding outdoor temperature as a selection condition for prevention operation, the mold prevention effect can be improved due to the incorrect indoor humidity detection value and the air treatment system not operating according to the preset mold prevention operation method. This can be avoided.

The machine is capable of performing the mold prevention operation, and when the first indoor unit starts the mold prevention operation, the four-way valve is in a switching state that allows the air conditioner to perform the heating operation. is detected, and when any one of the at least one second indoor unit is in heating operation, when the indoor temperature is higher than the first indoor temperature, the four-way valve is turned on to the air conditioner. On the other hand, when the first indoor unit starts the mold prevention operation, the four-way valve causes the air conditioner to perform the cooling operation or the dehumidification operation. If it is detected that a switching state that can be executed is detected, and any one of the at least one second indoor unit is in cooling operation, the indoor temperature becomes the second indoor temperature. When the value is smaller than , the four-way valve is not switched to a switching state that allows the air conditioner to perform heating operation.

（空気処理システムの運転）
空気処理システム１では、制御手段１３０は、室内検出手段１２０によって取得された温度データ、湿度データに基づき、空気処理システム１の運転を制御し、空気処理システム１によって調節される対象空間の相対湿度Ｈ％が第１の目標相対湿度Ｈｓｔ％よりも大きい場合、空気処理システム１にカビ防止運転を実行させ、カビ防止運転中に、室内温度Ｔｉが第１の室内温度Ｔ１よりも大きい場合、制御手段１３０は、空気処理システム１に冷房運転を実行させるが、室内温度Ｔｉが第２の室内温度Ｔ２よりも小さい場合、制御手段１３０は、空気処理システム１に暖房運転を実行させ、ここに、第２の室内温度Ｔ２が第１の室内温度Ｔ１よりも小さい。(Operation of air treatment system)

また、図３に示されるように、空気処理システム１によるカビ防止運転が開始した（ステップＳＴ１）後、空調装置１１０が起動され、室外機１１１において、圧縮機１１１１が作動し、室外ファン１１１４が作動するようになり、また、例えば、第１の室内機１１２Ａが起動されると、その室内ファン１１２３が作動することにより、空調装置１１０は、冷媒回路内における冷媒の流動によって冷房運転又は暖房運転を実行する。その状態では、第１の室内機１１２Ａによるカビ防止運転が起動されると、制御手段１３０は、四方弁１１１２の現在の切換え状態を検出する（ステップＳＴ２）。カビ防止運転の起動時、四方弁１１１２が空調装置１１０に暖房運転を実行させることができる切換え状態にあることが検出された場合、室内温度Ｔｉが第１の室内温度Ｔ１（例えば２２℃）よりも大きいか否かを判断し（ステップＳＴ３）、室内温度Ｔｉが第１の室内温度Ｔ１よりも大きいときに、制御手段１３０は、四方弁１１１２を空調装置１１０に冷房運転を実行させることができる切換え状態に切り換え、それに対して、室内温度Ｔｉが第１の室内温度Ｔ１以下である場合、制御手段１３０は、空調装置１１０に暖房乾燥運転を直接に実行させる（ステップＳＴ５）。一方、カビ防止運転の起動時、四方弁１１１２が空調装置１１０に冷房運転を実行させることができる切換え状態にあることが検出された場合、室内温度Ｔｉが第２の室内温度Ｔ２（例えば１８℃）よりも小さいか否かを判断し（ステップＳＴ６）、室内温度Ｔｉが第２の室内温度Ｔ２よりも小さいときに、制御手段１３０は、四方弁１１１２を空調装置１１０に暖房運転を実行させることができる切換え状態に切り換え、それに対して、室内温度Ｔｉが第２の室内温度Ｔ２以上である場合、制御手段１３０は、空調装置１１０に冷房運転を直接に実行させる（ステップＳＴ４）。 Further, as shown in FIG. 3, after the mold prevention operation by the air treatment system 1 has started (step ST1), the air conditioner 110 is started, the compressor 1111 is activated in the outdoor unit 111, and the outdoor fan 1114 is activated. For example, when the first indoor unit 112A is activated, its indoor fan 1123 is activated, and the air conditioner 110 is operated in a cooling operation or a heating operation by the flow of refrigerant in the refrigerant circuit. Execute. In this state, when the mold prevention operation by the first indoor unit 112A is started, the control means 130 detects the current switching state of the four-way valve 1112 (step ST2). When starting the mold prevention operation, if it is detected that the four-way valve 1112 is in a switching state that allows the air conditioner 110 to perform heating operation, the indoor temperature Ti is lower than the first indoor temperature T1 (for example, 22 degrees Celsius). (step ST3), and when the indoor temperature Ti is greater than the first indoor temperature T1, the control means 130 can cause the four-way valve 1112 to cause the air conditioner 110 to perform cooling operation. In contrast, when the indoor temperature Ti is equal to or lower than the first indoor temperature T1, the control means 130 causes the air conditioner 110 to directly perform the heating and drying operation (step ST5). On the other hand, when starting the mold prevention operation, if it is detected that the four-way valve 1112 is in a switching state that allows the air conditioner 110 to perform the cooling operation, the indoor temperature Ti is changed to the second indoor temperature T2 (for example, 18° C. ) (step ST6), and when the indoor temperature Ti is smaller than the second indoor temperature T2, the control means 130 controls the four-way valve 1112 to cause the air conditioner 110 to perform heating operation. If the indoor temperature Ti is equal to or higher than the second indoor temperature T2, the control means 130 causes the air conditioner 110 to directly perform the cooling operation (step ST4).

ちなみに、本実施形態では、上記ステップＳＴ４は、空調装置１１０が実行する所定の冷房運転によって実現され、当該所定の冷房運転では、例えば、第１の室内機１１２Ａの送風温度を１６℃に設定する。しかも、本実施形態では、上記ステップＳＴ５は、空調装置１１０が実行する所定の暖房運転によって実現され、当該所定の暖房運転では、例えば、室内機の送風温度を室内温度よりも２℃高いように設定する。 Incidentally, in the present embodiment, step ST4 is realized by a predetermined cooling operation performed by the air conditioner 110, and in the predetermined cooling operation, the air temperature of the first indoor unit 112A is set to 16° C., for example. . Moreover, in the present embodiment, step ST5 is realized by a predetermined heating operation performed by the air conditioner 110, and in the predetermined heating operation, for example, the air temperature of the indoor unit is set to be 2° C. higher than the indoor temperature. Set.

また、冷房運転（図３中のステップＳＴ４を参照）と暖房乾燥運転（図３中のステップＳＴ５を参照）とはいずれも、除湿を実現することができるが、両者の除湿原理は異なるものである。具体的には、冷房運転の実行時、室内温度の低下に伴い、空気中の水分飽和濃度が低下するため、温度を低下させる方式により、空気中の水分を凝縮析出して、空気の絶対湿度を低下させ、さらに、空気の相対湿度を低下させることができる。それに対して、暖房乾燥運転の実行時、室内温度の上昇に伴い、空気中の水分飽和濃度が上昇するため、空気の相対湿度も対応して低下する。 Furthermore, both cooling operation (see step ST4 in Figure 3) and heating drying operation (see step ST5 in Figure 3) can achieve dehumidification, but the dehumidification principles of the two are different. be. Specifically, when performing cooling operation, as the indoor temperature decreases, the saturation concentration of moisture in the air decreases. can further reduce the relative humidity of the air. On the other hand, when the heating and drying operation is performed, as the indoor temperature increases, the saturation concentration of water in the air increases, and the relative humidity of the air also decreases accordingly.

また、本実施形態では、空調装置１１０は、１台の第１の室内機１１２Ａと、１台の第２の室内機１１２Ｂを含み、第１の室内機１１２Ａは、カビ防止運転を実行することができ、第１の室内機１１２Ａによるカビ防止運転の起動時、四方弁１１１２が空調装置１１０に暖房運転を実行させる切換え状態にあり、かつ、第２の室内機１１２Ｂが暖房運転にある場合、室内温度Ｔｉが第１の室内温度Ｔ１よりも大きいとき、空調装置１１０を冷房運転に切り換えなく、一方、第１の室内機１１２Ａによるカビ防止運転の起動時、四方弁１１１２が空調装置１１０に冷房運転を実行させる切換え状態にあり、かつ、第２の室内機１１２Ｂが冷房運転にある場合、室内温度Ｔｉが第２の室内温度Ｔ２よりも小さいとき、空調装置１１０を暖房運転に切換えない。 Further, in this embodiment, the air conditioner 110 includes one first indoor unit 112A and one second indoor unit 112B, and the first indoor unit 112A is configured to perform mold prevention operation. is possible, and when the first indoor unit 112A starts the mold prevention operation, the four-way valve 1112 is in a switching state to cause the air conditioner 110 to execute the heating operation, and the second indoor unit 112B is in the heating operation, When the indoor temperature Ti is higher than the first indoor temperature T1, the air conditioner 110 is not switched to cooling operation, and on the other hand, when the first indoor unit 112A starts the mold prevention operation, the four-way valve 1112 switches the air conditioner 110 to the cooling operation.
