Description

本発明は切りタイマ機能を有する空気調和機の快適制御に関するものである。   The present invention relates to comfort control of an air conditioner having a cut-off timer function.

図3は従来の空気調和機の一般的な構成を示す制御ブロック図である。従来、この種の技術は切りタイマが終了しても一定時間強制的に運転し、その後ドライ或いは送風運転を更に一定時間継続する制御としている(例えば、特許文献1参照)。   FIG. 3 is a control block diagram showing a general configuration of a conventional air conditioner. Conventionally, this type of technology is controlled so that a forced operation is performed for a certain period of time after the turn-off timer has expired, and then the dry or air blowing operation is continued for a certain period of time (see, for example, Patent Document 1).

特開昭55−102852号公報JP-A-55-102852

しかしながら、前記従来の構成では切りタイマ終了後も必ず一定時間タイマ終了前の運転を継続し、更にその後、冷房或いは送風運転を一定時間実施する構成なので、室内の空調負荷が低下し空気調和機の運転が不要になったにも係わらず空気調和機が運転を継続するため、近年話題となっている省エネ性の観点において、又利用者に風を当て続けるため健康上の問題において課題を有していた。   However, in the above-described conventional configuration, the operation before the end of the timer is always continued after the end of the turn-off timer, and thereafter, the cooling or blowing operation is performed for a predetermined time. The air conditioner continues to operate despite the fact that it is no longer necessary to operate, so it has problems in terms of energy conservation, which has become a hot topic in recent years, and health problems in order to keep the user on the wind. It was.

本発明は、前記従来の課題を解決するもので、切りタイマ終了後において屋内外の空調負荷と屋外空気の汚れ度合いによっては追加の冷房または除湿運転を行わずに、屋内の空気を屋外に排出し屋外の空気を屋内に導入することで、省エネ性の向上と利用者に快適な空調を提供することを目的とする。   The present invention solves the above-mentioned conventional problems, and after the turn-off timer expires, indoor air is discharged to the outside without performing additional cooling or dehumidifying operation depending on the indoor / outdoor air conditioning load and the degree of contamination of outdoor air. The purpose is to improve the energy saving and provide comfortable air conditioning for users by introducing outdoor air indoors.

前記従来の課題を解決するために、本発明の空気調和機は、人体付近の温度を検出する人体付近温検出手段と、屋外の温度を検知する外気温度検出手段と、空気調和機の吸込温度を検知する吸込温度検出手段と、空気調和機の制御目標室温を設定する温度設定手段と、屋外空気の汚れ度合いを判定する汚れ度合い検出手段と、運転時間をタイマ設定値と比較しタイマ設定値に達した時に空気調和機の運転を停止する切りタイマ手段と、人の存在、不在を検知する人体検知手段と、屋内の空気を屋外に排出しかつ屋外の空気を屋内に導入する換気手段を備え、切タイマ動作終了後の運転モードとして、人が存在する場合において、人体付近の温度が第1の所定温度より高く、かつ屋外温度が第2の所定温度より低くかつ屋外空気の汚れ度合いが低い場合、前記換気手段により屋外の空気を屋内に導入し、人体付近の温度が第1の所定温度より高く、かつ屋外温度が第2の所定温度より低くかつ屋外空気の汚れ度合いが高い場合、又は人体付近の温度が第1の所定温度より高くかつ屋外温度が第2の所定温度より高い場合は、換気は行わずに冷房又は除湿運転を行う制御手段を設けたものである。   In order to solve the above-described conventional problems, an air conditioner of the present invention includes a human body temperature detecting unit that detects a temperature near the human body, an outside air temperature detecting unit that detects an outdoor temperature, and an intake temperature of the air conditioner. A suction temperature detecting means for detecting air temperature, a temperature setting means for setting a control target room temperature of the air conditioner, a dirt degree detecting means for judging the degree of dirt in outdoor air, and a timer set value by comparing the operation time with a timer set value. A timer means for stopping the operation of the air conditioner when it reaches the limit, a human body detecting means for detecting the presence or absence of a person, and a ventilation means for discharging indoor air to the outside and introducing outdoor air to the indoor As an operation mode after the end of the timer operation, when a person is present, the temperature near the human body is higher than the first predetermined temperature, the outdoor temperature is lower than the second predetermined temperature, and the degree of outdoor air contamination is If the outdoor air is introduced indoors by the ventilation means, the temperature near the human body is higher than the first predetermined temperature, the outdoor temperature is lower than the second predetermined temperature, and the degree of contamination of the outdoor air is high, Alternatively, when the temperature in the vicinity of the human body is higher than the first predetermined temperature and the outdoor temperature is higher than the second predetermined temperature, control means for performing cooling or dehumidifying operation without performing ventilation is provided.

これによって、空調負荷が大きいまたは屋外空気の汚れ度合いが高い時には追加で運転を行い、利用者が不快感なく就寝できる。また空調負荷が小さい時には余分な運転をせず、温度の高い屋内空気を排出し、屋外より温度が低くかつ汚れ度合いの低い空気を導入することで快適性の向上を図ると共に、無駄なエネルギーの消費を防止することができる。   As a result, when the air-conditioning load is large or the degree of dirt in the outdoor air is high, additional driving is performed, and the user can go to bed without discomfort. In addition, when the air conditioning load is low, it does not operate excessively, exhausts hot indoor air, introduces air that is cooler and less dirty than the outdoors, and improves comfort and wastes energy. Consumption can be prevented.

本発明は、人体付近の温度を検出する人体付近温度検出手段と、屋外の温度を検知する外気温度検出手段と、空気調和機の吸込温度を検知する吸込温度検出手段と、室温を設定する温度設定手段と、運転時間をタイマ設定値と比較しタイマ設定値に達した時に空気調和機の運転を停止する切りタイマ手段と、人の存在、不在を検知する人体検知手段と、室外の空気を室内に導入する換気手段とを備え、人が存在する場合において、切タイマ動作終了後に、人体付近の温度が第1の所定温度より高く、屋外温度が第2の所定温度より低くかつ屋外空気の汚れ度合いが低い場合、換気手段により屋内の空気を屋外に排出して屋外の空気を屋内に導入する。また、人体付近の温度が第1の所定温度より高く、かつ屋外温度が第2の所定温度より低く、かつ屋外空気の汚れ度合いが高い場合、または人体付近の温度が第1の所定温度より高く、屋外温度が第2の所定温度より高い場合は、冷房運転を行うようにしたものである。   The present invention includes a human body temperature detecting means for detecting a temperature in the vicinity of a human body, an outside air temperature detecting means for detecting an outdoor temperature, a suction temperature detecting means for detecting a suction temperature of an air conditioner, and a temperature for setting a room temperature. A setting means, a turn-off timer means for stopping the operation of the air conditioner when the operation time is compared with the timer set value, a human body detecting means for detecting the presence or absence of a person, and outdoor air Ventilation means to be introduced indoors, and when there is a person, after the end of the timer operation, the temperature near the human body is higher than the first predetermined temperature, the outdoor temperature is lower than the second predetermined temperature, and the outdoor air When the degree of contamination is low, indoor air is discharged outdoors by ventilation means and the outdoor air is introduced indoors. Further, when the temperature near the human body is higher than the first predetermined temperature, the outdoor temperature is lower than the second predetermined temperature, and the degree of outdoor air contamination is high, or the temperature near the human body is higher than the first predetermined temperature. When the outdoor temperature is higher than the second predetermined temperature, the cooling operation is performed.

これによって、空調負荷が大きい時には追加で運転を行い、利用者が不快感なく就寝できる。また空調負荷が小さい時には余分な冷房運転をせず換気運転をすることで、快適性を損なうことなく無駄なエネルギーの消費を防止可能となる。   As a result, when the air conditioning load is large, additional driving is performed, and the user can go to bed without discomfort. Further, when the air-conditioning load is small, it is possible to prevent wasteful energy consumption without impairing comfort by performing ventilation operation without excessive cooling operation.

また、人が存在しない場合は本制御を実施しないため、無駄な運転を防止することができる。   Moreover, since this control is not performed when there is no person, useless driving can be prevented.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(実施の形態1)
図1は、本発明の実施の形態1における空気調和機の制御ブロック図を示すものである。図1において、切タイマ手段1はタイマ設定値と運転時間の比較を常に行い、タイマ設定時間に達した場合制御手段9に空気調和機の停止信号を送信する。この停止信号の受信後に、人体付近温検出手段2、外気温度検出手段3、汚れ度合い検出手段7の各検出値に従って空気調和機の動作を決定する。以上のように構成された空気調和機について、以下その動作、作用を説明する。
(Embodiment 1)
FIG. 1 is a control block diagram of the air conditioner according to Embodiment 1 of the present invention. In FIG. 1, the off timer means 1 always compares the timer set value with the operation time, and transmits the air conditioner stop signal to the control means 9 when the timer set time is reached. After receiving this stop signal, the operation of the air conditioner is determined according to the detection values of the human body vicinity temperature detection means 2, the outside air temperature detection means 3, and the contamination degree detection means 7. About the air conditioner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

図2は本発明の実施の形態1における空気調和機の動作を示すフローチャートで、ステップ1、ステップ2にて切タイマ時間の判定を実施する。切タイマ時間に達した場合はステップ3でエアコンを停止させる。ステップ4では人体検知手段8により人の存在、不在を判定する。人が存在しない場合はステップ7でエアコン停止とする。人が存在する場合はステップ5に進む。   FIG. 2 is a flowchart showing the operation of the air conditioner according to Embodiment 1 of the present invention. If the timer time is reached, the air conditioner is stopped in step 3. In step 4, the presence or absence of a person is determined by the human body detection means 8. If no person is present, the air conditioner is stopped in step 7. If a person exists, go to step 5.

ステップ5では人体付近温度の検出を行う。この時、人体付近の温度が所定温度T1℃
よりも低い場合はエアコンを運転する必要がないため、ステップ6で切りタイマ動作による停止状態を継続したままとする。人体付近の温度が所定温度T1℃より高い場合はステップ6にて外気温度の判定を行う。この時、外気温度が所定温度T2℃より高い場合は、切りタイマ動作後において空調負荷大と判定しステップ8でエアコンを冷房運転させる。また、外気温度が所定温度T2℃より低い場合はステップ9で外気の汚れ度合いを判定する。
In step 5, the temperature near the human body is detected. At this time, the temperature near the human body is a predetermined temperature T1 ° C.
If it is lower than that, the air conditioner does not need to be operated, so in step 6, the stop state by the timer operation is continued. If the temperature in the vicinity of the human body is higher than the predetermined temperature T1 ° C., the outside air temperature is determined in step 6. At this time, if the outside air temperature is higher than the predetermined temperature T2 ° C., it is determined that the air conditioning load is large after the turn-off timer operation, and the air conditioner is cooled in step 8. On the other hand, if the outside air temperature is lower than the predetermined temperature T2 ° C., the degree of contamination of the outside air is determined at step 9.

外気の汚れ度合いが高い場合はステップ8で冷房運転を行い、外気の汚れ度合いが低い場合はステップ10にてエアコンを換気運転させる。これにより、外気の汚れ度合いが低い場合においては、屋内の高温空気を屋外に排出し、屋外の低温空気を屋内に導入することで室温を下げることができる。   If the outside air is dirty, the air conditioning operation is performed in step 8; if the outside air is dirty, the air conditioner is ventilated in step 10. Thereby, when the degree of dirt of the outside air is low, the room temperature can be lowered by discharging indoor high-temperature air to the outdoors and introducing outdoor low-temperature air to the indoors.

以上のように、本実施の形態においては切タイマ動作終了後の空気調和機の運転モードとして、人の存在、不在を判定し、人が存在する場合において、人体付近の温度が低い場合には停止状態を継続し、人体付近の温度が高く、外気温度も高い空調負荷状態においては追加で冷房運転をおこなうことで、利用者が不快感なく就寝できる。   As described above, in the present embodiment, as the operation mode of the air conditioner after the end of the timer operation, the presence or absence of a person is determined, and when a person is present and the temperature near the human body is low, The user can go to bed without discomfort by continuing the stopped state and additionally performing the cooling operation in an air conditioning load state where the temperature near the human body is high and the outside air temperature is high.

また人体付近の温度が高く、外気温度が低く、かつ外気の汚れ度合いが低い場合は換気運転を行うことで、特に夏場において切りタイマ動作後のエアコン停止中での個室の壁面、天井からの輻射熱による室温上昇の場合でも冷房運転を行うことなく室温を下げることができ快適な空調を実現でき、また省エネルギーの点からも無駄なエネルギーの消費を防止する等の効果を有するものである。   In addition, if the temperature near the human body is high, the outside air temperature is low, and the outside air is dirty, the ventilation operation is performed. In particular, the radiant heat from the wall and ceiling of the private room when the air conditioner is stopped after the timer is turned off in summer. Even when the room temperature rises due to the above, it is possible to lower the room temperature without performing the cooling operation, to realize a comfortable air conditioning, and to prevent useless energy consumption from the viewpoint of energy saving.

また、人が存在しない場合は本制御を実施しないため、無駄な運転を防止することができる。   Moreover, since this control is not performed when there is no person, useless driving can be prevented.

以上のように、本発明にかかる空気調和機は、切りタイマ動作後の運転モードについて人の存在、不在を判定し、人が存在する場合において、空調負荷が大きい時には追加で冷房運転を行い、利用者が不快感なく就寝できる。また空調負荷が小さい時には冷房運転ではなく、換気運転を行うことで、余分な冷房運転をせず無駄なエネルギーの消費を防止できるので、切りタイマ機能を有する空気調和機の快適制御の用途に有用である。   As described above, the air conditioner according to the present invention determines the presence or absence of a person with respect to the operation mode after the turn-off timer operation, and performs additional cooling operation when the air conditioning load is large in the presence of a person, Users can go to bed without discomfort. In addition, when the air conditioning load is small, ventilation operation is performed instead of cooling operation, so that unnecessary energy consumption can be prevented without excessive cooling operation. It is.
