特開２００１−２８９４５０号公報JP 2001-289450 A

従来の空調装置では、室内の暖房運転と乾燥運転と換気運転とが行えるように構成されているものの、その乾燥運転は、暖房運転と換気運転とを組み合わせただけであり、室内から吸引された空気の水蒸気を積極的に除湿する構成とはなっていない。そのため、室内の乾燥運転の効果が不十分なものとなっていた。   Although the conventional air conditioner is configured to perform indoor heating operation, drying operation, and ventilation operation, the drying operation is simply a combination of heating operation and ventilation operation, and is sucked from the room. It is not configured to actively dehumidify water vapor in the air. Therefore, the effect of the indoor drying operation is insufficient.

本発明は、上記の課題に鑑みてなされたものであり、その目的は、高いエネルギ効率で室内の乾燥運転が行えるコンパクトな空調装置を提供する点にある。   The present invention has been made in view of the above problems, and an object of the present invention is to provide a compact air conditioner capable of performing indoor drying operation with high energy efficiency.

上記目的を達成するための本発明に係る空調装置の第１特徴構成は、室内から吸気路へ吸引した空気を吹出口から前記室内へ吹き出すように通風する循環手段と、前記吸気路に設けられてその吸気路を通流する空気を加熱する加熱器と、前記吸気路に設けられた前記加熱器を通流した空気の一部を排気路を通流させて排気する排気作動自在の排気手段とが設けられている空調装置であって、前記吸気路を通流する空気を除湿し、且つ、前記排気路を通流する空気によって再生される除湿作動自在なデシカントロータが、前記室内から吸引された空気を除湿した後で前記加熱器へ通流させるように、前記吸気路と前記排気路とに渡って設けられている点にある。 In order to achieve the above object, a first characteristic configuration of the air conditioner according to the present invention is provided in the air intake passage and circulation means for ventilating air sucked from the room to the air intake passage so as to blow out from the air outlet to the room. A heater for heating the air flowing through the intake passage, and an exhaust-operable exhaust means for exhausting a part of the air that has passed through the heater provided in the intake passage through the exhaust passage And a desiccant rotor capable of dehumidifying the air flowing through the intake passage and regenerated by the air flowing through the exhaust passage. It is in the point provided over the said intake passage and the said exhaust passage so that it may be made to flow through the said heater after dehumidified.

上記第１特徴構成によれば、室内から吸引された空気を除湿した後で加熱器へ通流させるように、吸気路と排気路とに渡って設けられているデシカントロータが、吸気を通流する空気を除湿し、且つ、排気路を通流する空気によって再生されるように作動する。
つまり、室内の乾燥運転を行うときには、上記加熱器、上記循環手段、上記デシカントロータ、及び、上記排気手段を併せて作動させることで、デシカントロータにおいて、室内から吸引された空気に含まれる湿気が液体から気体へと凝縮されると共に、凝縮した水分量に応じて凝縮熱によって空気が暖められ、次に加熱器にて加熱されて、暖房用の空気として室内に吹き出されることになる。その結果、デシカントロータによって積極的に除湿を行いながら空気の昇温が行われ、その後、加熱器において空気の加熱を行うように、デシカントロータと加熱器とをコンパクトに収容した上で上述のように連動させて運転させているので、室内の空気を暖めるために要するエネルギを低く抑えることが可能となる。
従って、高いエネルギ効率で室内の乾燥運転が行えるコンパクトな空調装置が提供されることになる。 According to the first characteristic configuration, the desiccant rotor provided across the intake passage and the exhaust passage is configured to flow the intake air so that the air sucked from the room is dehumidified and then passed to the heater. The air is dehumidified and is regenerated by the air flowing through the exhaust passage.
That is, when the indoor drying operation is performed, by operating the heater, the circulation unit, the desiccant rotor, and the exhaust unit together, in the desiccant rotor, moisture contained in the air sucked from the room is generated. Condensed from a liquid to a gas, the air is warmed by condensation heat in accordance with the amount of condensed water, and then heated by a heater and blown out indoors as heating air. As a result, the temperature of the air is raised while actively dehumidifying by the desiccant rotor, and then the desiccant rotor and the heater are accommodated in a compact manner so that the air is heated in the heater, as described above. Therefore, the energy required to warm the indoor air can be kept low.
Therefore, a compact air conditioner that can perform indoor drying operation with high energy efficiency is provided.

本発明に係る空調装置の第２特徴構成は、上記第１特徴構成に加えて、前記加熱器、前記排気手段、前記循環手段、及び、前記デシカントロータの作動を制御する制御手段が、前記加熱器を加熱作動させながら前記循環手段を作動させる暖房運転と、前記加熱器を加熱作動させながら前記排気手段と前記循環手段と前記デシカントロータとを作動させる乾燥運転と、前記排気手段を作動させる換気運転とを切替自在に構成されている点にある。 A second characteristic configuration of the air conditioner according to the present invention includes, in addition to the first characteristic configuration, a control unit that controls the operation of the heater, the exhaust unit, the circulation unit, and the desiccant rotor. Heating operation for operating the circulation means while heating the heater, drying operation for operating the exhaust means, the circulation means and the desiccant rotor while heating the heater, and ventilation for operating the exhaust means The point is that the operation can be switched.

上記第２特徴構成によれば、制御手段が、加熱器を加熱作動させながら循環手段を作動させることで室内の暖房運転が行われ、加熱器を作動させながら排気手段と循環手段とデシカントロータとを除湿作動させることで室内の乾燥運転が行われ、排気手段を排気作動させることで室内の排気運転が行われることになり、これら暖房運転と乾燥運転と排気運転とが自在に切り替えられるようになる。その結果、暖房運転と乾燥運転と排気運転とを行うことができる空調装置をコンパクトな構成としながらも、室内の環境を快適に保つことが可能となる。   According to the second feature configuration, the control means operates the circulation means while heating the heater, thereby heating the room, and the exhaust means, the circulation means, and the desiccant rotor are operated while the heater is operated. The indoor drying operation is performed by dehumidifying the air, and the indoor exhaust operation is performed by exhausting the exhaust means so that the heating operation, the drying operation, and the exhaust operation can be freely switched. Become. As a result, the indoor environment can be kept comfortable while the air conditioner capable of performing the heating operation, the drying operation, and the exhaust operation has a compact configuration.

以下に図面を参照して本発明の空調装置２０について説明する。
図１に示す空調装置２０には、室内から吸気路９へ吸引した空気をその吸気路９に設けられた加熱器１にて加熱して室内に通風するように加熱循環作動自在の循環手段としての循環ファン２と、吸気路９に設けられた加熱器１を通流した空気の一部を排気路１０を通流させて排気する排気作動自在の排気手段としての排気ファン３と、吸気路９を通流する空気を除湿し、且つ、排気路１０を通流する空気によって再生される除湿作動自在であり、室内から吸引された空気を除湿した後で加熱器１へ通流させるように、吸気路９と排気路１０とに渡って設けられているデシカントロータ４とが設けられている。 The air conditioner 20 of the present invention will be described below with reference to the drawings.
The air conditioner 20 shown in FIG. 1 serves as a circulation means that can be heated and circulated so that the air sucked into the intake passage 9 from the room is heated by the heater 1 provided in the intake passage 9 and ventilated into the room. Circulation fan 2, exhaust fan 3 serving as an exhaustable exhaust means for exhausting part of the air that has passed through heater 1 provided in intake path 9 through exhaust path 10, and intake path Dehumidifying the air flowing through 9 and regenerating the air regenerated by the air flowing through the exhaust passage 10 so that the air sucked from the room is dehumidified and then passed to the heater 1. A desiccant rotor 4 provided over the intake passage 9 and the exhaust passage 10 is provided.

加熱器１は、外部の熱源機１５にて加熱された熱媒が熱媒流入路１１から流入し、熱媒流出路１２からその熱源機１５へと帰還するように構成されたものであり、流入した高温の熱媒が吸気路９を通流する空気に対して放熱を行うことで、吸気路９を通流する空気の加熱が行われるようになっている。従って、制御部１３は、加熱器１を加熱作動させて、吸気路９を通流する空気を加熱させたいときには、熱源機１５から加熱器１へと熱媒が流入するように制御し、加熱器１を加熱作動させないときには、熱源機１５から加熱器１へと熱媒が流入しないように制御する。   The heater 1 is configured such that the heat medium heated by the external heat source device 15 flows in from the heat medium inflow passage 11 and returns to the heat source device 15 from the heat medium outflow passage 12. The inflowing high-temperature heat medium dissipates heat to the air flowing through the intake passage 9 so that the air flowing through the intake passage 9 is heated. Therefore, the control unit 13 controls the heating medium 1 to flow from the heat source unit 15 to the heating unit 1 when the heating unit 1 is heated and the air flowing through the intake passage 9 is heated. When the apparatus 1 is not heated, the heat medium is controlled so as not to flow into the heater 1 from the heat source unit 15.

デシカントロータ４は、除湿材が充填されて回転可能に構成され、吸気路９を通流する空気と接触した除湿材が、その空気中に含まれる水蒸気を吸着して除湿し、その後、排気路４側へと回転され、排気路４を通流する空気と接触したときに、その空気へ水蒸気を引き渡して除湿材が再生されるように作用する。つまり、室内から吸気路９へ流入した空気中に含まれて除湿材で吸収された水蒸気は、排気路４で除湿材が再生されたときに、排気路１０を通流する空気に引き渡されて屋外へと排気されることになる。   The desiccant rotor 4 is configured to be rotatable by being filled with a dehumidifying material, and the dehumidifying material in contact with the air flowing through the intake passage 9 adsorbs water vapor contained in the air and dehumidifies it, and then the exhaust passage. When rotated to 4 side and brought into contact with the air flowing through the exhaust passage 4, the dehumidifying material is regenerated by delivering water vapor to the air. That is, the water vapor contained in the air flowing into the intake passage 9 from the room and absorbed by the dehumidifying material is delivered to the air flowing through the exhaust passage 10 when the dehumidifying material is regenerated in the exhaust passage 4. It will be exhausted outdoors.

そして、この空調装置２０は、リモコン操作部１４からの指令によって室内の乾燥運転、暖房運転と室内温度、及び、換気運転を切替自在に構成されている。図１に例示するのは、リモコン操作部１４からの指令によって、制御部１３が空調装置２０を乾燥運転させている状態を示す図であり、図２に例示するのは制御部１３が空調装置２０を暖房運転させている状態を示す図であり、図３に例示するのは制御部１３が空調装置２０を換気運転させている状態を示す図である。   The air conditioner 20 is configured to be switchable between an indoor drying operation, a heating operation and a room temperature, and a ventilation operation according to a command from the remote control operation unit 14. Illustrated in FIG. 1 is a diagram showing a state in which the control unit 13 is causing the air conditioner 20 to dry in accordance with a command from the remote control operation unit 14, and illustrated in FIG. FIG. 3 is a diagram illustrating a state in which the control unit 13 causes the air conditioner 20 to perform a ventilation operation.

図１に示した空調装置２０の乾燥運転について説明すると、制御部１３は、熱源機１５から熱媒を流入させることで加熱器１を加熱作動させながら、排気ファン３と循環ファン２とデシカントロータ４とを作動（除湿作動）させている。その結果、吸気口６を経て室内から吸気路９に流入した空気は、デシカントロータ４によって除湿され、加熱器１によって加熱された後、ルーバ５で風向を制御されながら吹出口７から室内へと吹き出される。また、デシカントロータ４によって除湿され、加熱器１によって加熱された空気の一部は、排気ファン３が作動することによって生じる吸引力によって排気路１０に流入し、デシカントロータ４と接触した後で排気口８から屋外へと排気される。そして、デシカントロータ４によって除湿され、加熱器１によって加熱された空気とデシカントロータ４とが接触するとき、温度の高い乾燥した空気と水蒸気を含んだ除湿材とが接触することになるため、その除湿材の再生が行われることになり、同時に屋外へ排出される空気の湿度が上昇することになる。   Explaining the drying operation of the air conditioner 20 shown in FIG. 1, the control unit 13 heats the heater 1 by flowing a heat medium from the heat source unit 15, while operating the exhaust fan 3, the circulation fan 2, and the desiccant rotor. 4 is operated (dehumidifying operation). As a result, the air flowing into the intake passage 9 from the room through the intake port 6 is dehumidified by the desiccant rotor 4, heated by the heater 1, and then from the blowout port 7 to the room while the air direction is controlled by the louver 5. Blown out. Further, a part of the air dehumidified by the desiccant rotor 4 and heated by the heater 1 flows into the exhaust passage 10 by the suction force generated by the operation of the exhaust fan 3, and is exhausted after contacting the desiccant rotor 4. The air is exhausted from the mouth 8 to the outside. And, when the air dehumidified by the desiccant rotor 4 and the air heated by the heater 1 and the desiccant rotor 4 come into contact with each other, the high-temperature dry air and the dehumidifying material containing water vapor come into contact with each other. Regeneration of the dehumidifying material will be performed, and at the same time, the humidity of the air discharged outdoors will increase.

図２に示した空調装置２０の暖房運転について説明すると、制御部１３は、熱源機１５から熱媒を流入させることで加熱器１を加熱作動させながら循環ファン２を作動（暖房作動）させている。このとき、デシカントロータ４と排気ファン３とは作動していない。その結果、吸気口６を経て室内から吸気路９に流入した空気は、加熱器１によって加熱された後、ルーバ５で風向を制御されながら吹出口７から室内へと吹き出される暖房運転が行われる。   The heating operation of the air conditioner 20 shown in FIG. 2 will be described. The control unit 13 operates the circulation fan 2 (heating operation) while heating the heater 1 by flowing a heat medium from the heat source unit 15. Yes. At this time, the desiccant rotor 4 and the exhaust fan 3 are not operating. As a result, after the air flowing into the intake passage 9 from the room through the intake port 6 is heated by the heater 1, the heating operation is performed in which the air direction is controlled by the louver 5 and blown out from the air outlet 7 into the room. Is called.

図３に示した空調装置２０の換気運転について説明すると、制御部１３は、排気ファン３を作動（換気作動）させている。このとき、熱源機１５から加熱器１への熱媒の流入は行われず、デシカントロータ４及び循環ファン２は作動されず、ルーバ５は閉じられている。その結果、排気ファン３の吸引力が作動することによって生じる吸引力によって吸気口６を経て室内から吸気路９に流入された空気は、排気路１０を経て排気口８から屋外に排出されることになる。   The ventilation operation of the air conditioner 20 shown in FIG. 3 will be described. The control unit 13 operates the exhaust fan 3 (ventilation operation). At this time, the flow of the heat medium from the heat source unit 15 to the heater 1 is not performed, the desiccant rotor 4 and the circulation fan 2 are not operated, and the louver 5 is closed. As a result, the air that flows into the intake passage 9 from the room through the intake port 6 due to the suction force generated by the operation of the suction force of the exhaust fan 3 is discharged from the exhaust port 8 to the outside through the exhaust passage 10. become.

以上のように、制御部１３が、加熱器１を加熱作動させながら循環ファン２を作動させることで室内の暖房運転が行われ、加熱器１を作動させながら排気ファン３と循環ファン２とデシカントロータ４とを除湿作動させることで室内の乾燥運転が行われ、排気ファン３を排気作動させることで室内の排気運転が行われることになり、これら暖房運転と乾燥運転と排気運転とが自在に切り替えられるようになる。   As described above, the control unit 13 activates the circulation fan 2 while heating the heater 1, thereby heating the room. The exhaust fan 3, the circulation fan 2, and the desiccant are operated while the heater 1 is operated. The indoor drying operation is performed by dehumidifying the rotor 4, and the indoor exhaust operation is performed by exhausting the exhaust fan 3, and the heating operation, the drying operation, and the exhaust operation can be freely performed. Can be switched.

また、室内の乾燥運転を行うときには、上記加熱器１、上記循環ファン２、上記デシカントロータ４、及び、上記排気ファン３を併せて作動させることで、デシカントロータ４において、室内から吸引された空気に含まれる湿気が液体から気体へと凝縮されると共に、凝縮した水分量に応じて凝縮熱によって空気が暖められ、次に加熱器１にて加熱されて、暖房用の空気として室内に吹き出されることになる。つまり、単に加熱器１において空気の加熱を行うだけでなく、デシカントロータ４によって空気の昇温が行われるようになっているので、室内の空気を暖めるために要するエネルギを低く抑えることが可能となる。   Further, when the indoor drying operation is performed, the air sucked from the room in the desiccant rotor 4 by operating the heater 1, the circulation fan 2, the desiccant rotor 4 and the exhaust fan 3 together. The moisture contained in the water is condensed from liquid to gas, and the air is warmed by the heat of condensation according to the amount of condensed water, and then heated by the heater 1 and blown into the room as heating air. Will be. In other words, not only simply heating the air in the heater 1 but also increasing the temperature of the air by the desiccant rotor 4, it is possible to keep the energy required to warm the indoor air low. Become.

次に、図１に例示した本発明のデシカントロータ４を備えている空調装置２０を乾燥運転させたときの効果が、図４に例示するデシカントロータ４を備えていない従来型の空調装置３０を乾燥運転させたときの効果を上回っていることを表１から表３に示すシミュレーション結果に基づいて説明する。詳細には、デシカントロータ４を備えている空調装置２０と、デシカントロータ４を備えていない空調装置３０とを用いて、洗濯物が干されている浴室内の乾燥運転を行ったとき、乾燥運転開始直後と、洗濯物から水分が蒸発して湿度が最高になった時点と、その後の乾燥運転途中での室内温度、相対湿度、及び、絶対湿度を比較している。   Next, when the air conditioner 20 provided with the desiccant rotor 4 of the present invention illustrated in FIG. 1 is dried, the conventional air conditioner 30 not including the desiccant rotor 4 illustrated in FIG. It will be described based on the simulation results shown in Tables 1 to 3 that the effect of the drying operation is exceeded. Specifically, when the drying operation in the bathroom where the laundry is dried is performed using the air conditioner 20 including the desiccant rotor 4 and the air conditioner 30 not including the desiccant rotor 4, the drying operation is performed. The room temperature, the relative humidity, and the absolute humidity during the subsequent drying operation are compared immediately after the start, when the moisture is evaporated from the laundry and becomes the highest.

表１から表３において明らかであるように、本発明のデシカントロータ４を備えている空調装置２０を運転させたときの方が、絶対湿度（空気１ｋｇ中に含まれる水蒸気の量）が小さくなっており、デシカントロータ４によって積極的に除湿を行った効果が顕著に表れている。   As is apparent from Tables 1 to 3, the absolute humidity (the amount of water vapor contained in 1 kg of air) is smaller when the air conditioner 20 including the desiccant rotor 4 of the present invention is operated. Thus, the effect of positively dehumidifying with the desiccant rotor 4 is prominent.

また、図１に例示した本発明のデシカントロータ４を備えている空調装置２０を乾燥運転させるときに要するエネルギが、図４に例示するデシカントロータ４を備えていない従来型の空調装置３０を乾燥運転させるときに要するエネルギよりも低くなることについて表４に示すように両者を比較して説明する。   Further, the energy required for drying the air conditioner 20 including the desiccant rotor 4 of the present invention illustrated in FIG. 1 dries the conventional air conditioner 30 not including the desiccant rotor 4 illustrated in FIG. The fact that the energy is lower than that required for operation will be described by comparing the two as shown in Table 4.

表４及び表１から明らかであるように、３０℃の空気を５０℃にまで昇温しようとしたとき、デシカントロータ４の直後の空気の温度が４４℃にまで昇温されているので、加熱器１では、５０℃−４４℃＝６℃昇温させるだけの加熱を行えばよい。他方で、デシカントロータ４を備えていない従来の空調装置３０では、加熱器１において５０℃−３０℃＝２０℃昇温させるだけの加熱を行わねばならない。このように、本発明の空調装置２０では、デシカントロータ４において水分を凝縮させることに伴う空気の温度上昇により、加熱器１で必要となるエネルギ量を小さくすることが可能となる。   As apparent from Tables 4 and 1, when the temperature of 30 ° C. air was to be raised to 50 ° C., the temperature of the air immediately after the desiccant rotor 4 was raised to 44 ° C. In the vessel 1, it is only necessary to perform heating to raise the temperature by 50 ° C.-44 ° C. = 6 ° C. On the other hand, in the conventional air conditioner 30 that does not include the desiccant rotor 4, the heater 1 must be heated to raise the temperature by 50 ° C.-30 ° C. = 20 ° C. Thus, in the air conditioner 20 of the present invention, the amount of energy required for the heater 1 can be reduced due to the temperature rise of the air accompanying the condensation of moisture in the desiccant rotor 4.

また、表４及び表２から明らかであるように、４０℃の空気を６０℃にまで昇温しようとしたとき、デシカントロータ４の直後の空気の温度が５２℃にまで昇温されているので、加熱器１では、６０℃−５２℃＝８℃昇温させるだけの加熱を行えばよい。他方で、デシカントロータ４を備えていない従来の空調装置３０では、加熱器１において６０℃−４０℃＝２０℃昇温させるだけの加熱を行わねばならない。
同様に、表４及び表３から明らかであるように、４５℃の空気を６５℃にまで昇温しようとしたとき、デシカントロータ４の直後の空気の温度が５５℃にまで昇温されているので、加熱器１では、６５℃−５５℃＝１０℃昇温させるだけの加熱を行えばよい。他方で、デシカントロータ４を備えていない従来の空調装置３０では、加熱器１において６５℃−４５℃＝２０℃昇温させるだけの加熱を行わねばならない。 As is apparent from Tables 4 and 2, when the temperature of the 40 ° C. air is increased to 60 ° C., the temperature of the air immediately after the desiccant rotor 4 is increased to 52 ° C. In the heater 1, it is only necessary to perform heating to raise the temperature by 60 ° C-52 ° C = 8 ° C. On the other hand, in the conventional air conditioner 30 that does not include the desiccant rotor 4, the heater 1 must perform heating to raise the temperature by 60 ° C.−40 ° C. = 20 ° C.
Similarly, as apparent from Tables 4 and 3, when trying to raise the temperature of 45 ° C. air to 65 ° C., the temperature of the air immediately after the desiccant rotor 4 is raised to 55 ° C. Therefore, the heater 1 may be heated to raise the temperature by 65 ° C.-55 ° C. = 10 ° C. On the other hand, in the conventional air conditioner 30 that does not include the desiccant rotor 4, the heater 1 must be heated to raise the temperature by 65 ° C.-45 ° C. = 20 ° C.

以上のように、デシカントロータ４において、室内から吸引された空気に含まれる湿気が液体から気体へと凝縮されると共に凝縮した水分量に応じて空気が暖められ、次に加熱器１にて加熱されて、暖房用の空気として室内に吹き出されることになることで、単に加熱器１において空気の加熱を行うだけでなく、デシカントロータ４によって空気の昇温が行われるようになっているので、室内の空気を暖めるために要するエネルギを低く抑えることが可能となる。   As described above, in the desiccant rotor 4, the moisture contained in the air sucked from the room is condensed from the liquid to the gas, and the air is warmed according to the amount of condensed water, and then heated by the heater 1. Since the air is blown into the room as heating air, the air is heated not only by the heater 1 but also by the desiccant rotor 4. The energy required to warm the indoor air can be kept low.
