- FIG. 2 is a diagram illustrating an example of changes over time in the indoor temperature and the refrigerant temperature of the indoor heat exchanger 25 when the cooling operation is performed with the rotation speed of the compressor 21 being constant in the first embodiment of the present invention.
- the indoor heat exchanger 25 functions as an evaporator. Therefore, the saturation temperature of the refrigerant is called the evaporation temperature.
- the cooling operation when the cooling operation is started at the start of the operation and the room temperature is lowered, the temperature of the air passing around the indoor heat exchanger 25 is lowered. Therefore, the low-temperature refrigerant in the indoor heat exchanger 25 is less likely to be evaporated and the amount of refrigerant gas is reduced, so that the pressure and the evaporation temperature are reduced.
- FIG. 3 is a diagram illustrating an example of changes over time in the indoor temperature and the refrigerant temperature in the indoor heat exchanger 25 when the heating operation is performed with the rotation speed of the compressor 21 being constant in the first embodiment of the present invention.
- the indoor heat exchanger 25 functions as a condenser. Therefore, the saturation temperature of the refrigerant is called the condensation temperature.
- the heating operation when the heating operation is started at the start of operation and the room temperature rises, the temperature of the air passing around the indoor heat exchanger 25 increases. Therefore, the high-temperature refrigerant in the indoor heat exchanger 25 becomes difficult to condense and liquefy, and the amount of refrigerant gas increases, so the pressure and the condensation temperature rise.
- FIG. 4 shows changes in the capacity (cooling capacity and heating capacity) Q, input W, and operating efficiency COP associated with fluctuations in the compressor rotation speed according to Embodiment 1 of the present invention at the start of operation and after changes in room temperature. It is a figure which shows an example compared by these.
- the refrigerant pressure inside the indoor heat exchanger 25 decreases from the start of operation to after the indoor temperature change, so the density of the refrigerant sucked by the compressor 21 decreases.
- the flow rate of the refrigerant circulating in the refrigeration cycle decreases. Therefore, the cooling capacity Q decreases from the start of operation to after the indoor temperature change.
- the suction pressure of the compressor 21, that is, the pressure on the low pressure side decreases, the pressure difference from the discharge pressure of the compressor 21, that is, the pressure on the high pressure side widens, so that the input W of the compressor 21 increases.
- the pressure of the refrigerant inside the indoor heat exchanger 25 increases from the start of operation to after the change in the indoor temperature. Decreases after temperature change. Further, since the discharge pressure of the compressor 21, that is, the pressure on the high pressure side, increases, the pressure difference from the suction pressure of the compressor 21, that is, the pressure on the low pressure side increases, so that the input W of the compressor 21 increases.
- the cooling capacity Q decreases from the start of operation to after the change in room temperature, and the input W tends to increase from the start of operation to after the change in room temperature.
- (Coefficient of Performance) decreases from the start of operation to after the room temperature has changed.
- the heating capacity Q decreases from the start of operation to after the indoor temperature change, and the input W tends to increase from the start of operation to after the indoor temperature change. It decreases after the room temperature changes. That is, in any case of the cooling operation and the heating operation, the operation efficiency COP of the air conditioner 1 decreases from the start of operation to after the indoor temperature change.
- the operating efficiency COP is a value obtained by dividing the cooling capacity Q or the heating capacity Q by the input W. That is, the operating efficiency COP is a value obtained by dividing the capability Q by the input W.
- the relationship between the capacity Q, the input W, and the operating efficiency COP is examined from the viewpoint of the displacement of the rotation speed of the compressor 21.
- the suction pressure relatively decreases and the discharge pressure increases, so the pressure ratio increases.
- the operating efficiency COP decreases.
- the operation efficiency COP is approximated to a linear expression of the capacity Q, it is expressed as the following expression (1).
- a and B are parameters indicating the operation efficiency COP characteristics, and are determined based on the configuration of the air conditioner 1 and the environmental conditions of the air conditioner 1. As shown in the equation (1), the operating efficiency COP is expressed as A obtained by multiplying A by the capability Q and adding B. Further, as described above, since the operation efficiency COP is a value obtained by dividing the capability Q by the input W, the following expression (2) is derived from the relational expression.
- the input W is represented by dividing the ability Q by Expression (1).
- the operation mode executed by the air conditioner 1 will be described.
- the air conditioning system includes, for example, normal control and energy saving control as operation modes.
- the normal control the rotational speed of the compressor 21 is controlled according to the difference between the room temperature and the set temperature.
- Energy saving control reduces power consumption compared to normal control.
- the air conditioning system switches between normal control and energy saving control by turning on and off the energy saving mode selected by the user, for example.
- the air conditioning system switches to energy saving control when the energy saving mode is selected, and switches to normal control when the energy saving mode is selected to be off. For example, when the user transmits an operation start command for the air conditioner 1 to the indoor unit 13 with the energy saving mode selected via the remote controller 55, the air conditioner 1 operates with the energy saving control.
- the air conditioning system designates the room temperature to reach the target temperature at the designated time.
- the air conditioner 1 can be started from before the time, and the precooling / preheating operation which is the forward operation control by the energy saving control can be performed.
- the remote controller 55 is used to select the energy saving mode, send the operation start command, and set the timer reservation has been described.

- the eighth calculation unit 144 supplies an energy saving control command to the energy saving control unit 92 when the precooling pre-warming start time has arrived.
- the operation capacity of the air conditioner 1 is controlled so as to minimize the amount of power consumed from the start of operation until the room temperature reaches the target temperature. That is, the air conditioning system executes energy saving control that significantly reduces the total power consumption from the start of the operation of the air conditioner 1 until the room temperature reaches the target temperature.
- the point to note when performing energy-saving control is that if the rotational speed of the compressor 21 is simply reduced compared with the normal control, the operating efficiency COP is improved, but the capacity Q is lowered, so that the room temperature reaches the set temperature. It may be lost or it may take some time for the room temperature to reach the set temperature. Therefore, the air conditioning system needs to appropriately control the rotation speed of the compressor 21 when executing the energy saving control. Therefore, the operation principle of appropriate control will be described below.
- FIG. 8 shows changes in the time interval ⁇ t and the power consumption per time interval ⁇ t corresponding to a change in the room temperature of 1 ° C. accompanying the change in the compressor rotation speed in the first embodiment of the present invention. It is a figure which shows an example compared with after temperature change. In FIG. 8, description will be made assuming that a hollow circle means an operating point of energy saving control.
- the capacity Q of the air conditioner 1 decreases as the rotational speed of the compressor 21 decreases. Therefore, from the equation (3) described above, the time interval ⁇ t increases as the rotational speed of the compressor 21 decreases. Further, from the equation (3) described above, since the room temperature does not change at the rotation speed of the compressor 21 at which the capacity Q of the air conditioner 1 and the thermal load D are equal, the time interval ⁇ t is infinite. Become.
- the thermal load D increases as the temperature difference between the outside air temperature and the room temperature increases. For example, if the outside air temperature is 30 ° C. and the room temperature is 30 ° C. at the start of operation of the air conditioner 1, the temperature difference between the outside air temperature and the room temperature is 0 ° C. Further, if the outside air temperature is 30 ° C. and the room temperature is 25 ° C. after the start of the operation of the air conditioner 1, the temperature difference between the outside air temperature and the room temperature is 5 ° C. Therefore, the heat load D becomes larger after the indoor temperature change than when the operation is started. Accordingly, the time interval ⁇ t takes longer for ⁇ t 2 after the indoor temperature change than for the time ⁇ t 1 at the start of operation.
- the power consumption per time interval ⁇ t has a minimum point.
- the compressor rotational speed is increased from the minimum point, the input W increases and the operating efficiency COP decreases, so that the power consumption increases.
- the time interval ⁇ t is extended, so that the power consumption increases.
- the operation efficiency COP has a smaller slope ( ⁇ A) and becomes gentler after the change in the room temperature than at the start of operation.
- ⁇ A the refrigerant saturation temperature of the indoor heat exchanger 25
- the optimum compressor rotation speed N may be commanded and the set temperature may be commanded at every time interval ⁇ t.
- the cooling capacity Q or the heating capacity Q includes sensible heat and latent heat. However, since the sensible heat capacity affects the change in the room temperature, the cooling capacity Q or the heating capacity Q is the sensible heat component. It is good also as ability Q only.
- the rotational speed of the compressor 21 that is the minimum amount of power consumption and the time interval ⁇ t corresponding to a change in the room temperature of 1 ° C. are linked via the thermal load D, and the set temperature If the set temperature is set with a step size of 1 ° C., and the set temperature is linked step by step with the rotation speed of the compressor 21 having the minimum power consumption, the time interval can be changed. The amount of power consumed by the compressor 21 during ⁇ t is minimized. Therefore, the total power consumption from when the operation of the air conditioner 1 is started until the room temperature reaches the target temperature can be greatly reduced. Therefore, the air conditioning system can perform an energy saving operation with less power consumption by increasing the operation efficiency of the air conditioner 1.

- the air conditioning system sets the set temperature to the room temperature + 1 ° C. at the start of operation, and increases the set temperature by 1 ° C. after the time interval ⁇ t 1 has elapsed. After the change in room temperature, the set temperature is increased by 1 ° C. after the time interval ⁇ t 2 has elapsed.
- the compressor speed is controlled according to the temperature difference between the set temperature and the room temperature in the same manner as in the normal control, the air conditioning system is controlled at a speed close to N 1 to N 2 as a result.
- the present invention is not particularly limited thereto.
- the time interval ⁇ t corresponding to a change in the room temperature of 0.1 ° C. may be associated with the compressor speed at which the power consumption of the compressor 21 is minimized.
- the time interval ⁇ t corresponding to the change in the indoor temperature of 1.75 ° C. may be associated with the compressor rotation speed at which the power consumption of the compressor 21 is minimized.

- the operating capacity of the air conditioner 1 is determined. By determining the operating capacity of the air conditioner 1 in this manner, the air conditioning system can minimize the total power consumption until the room temperature reaches the target temperature, that is, the power consumption.
- the air conditioning system performs a highly efficient operation by operating the operation capacity of the compressor 21, that is, the rotation speed of the compressor 21 with an appropriately low capacity.
- the air conditioning system in the normal control, when the temperature difference between the room temperature and the set temperature is large, the air conditioning system is operated so as to quickly eliminate this temperature difference. Therefore, in the air conditioning system, the operation capacity of the compressor 21 is increased in the normal control. Therefore, in the air conditioning system, in normal control, although the change in the room temperature is accelerated and the deterioration of the comfort of the user can be suppressed to the minimum, the operation capacity COP is increased by the corresponding increase in the operation capacity. Decreases and the power consumption of the air conditioner 1 increases.

The amount of power can be reduced.
- the control part which controls the air conditioner 1 is provided, and a control part is compared with normal control and normal control.
- the air conditioner 1 is controlled by switching between energy saving control for reducing the power consumption, and in the case of normal control, the rotation speed of the compressor 21 is controlled according to the difference between the room temperature and the set temperature.

Abstract
Description
<全体概要>
空気調和システムは、省エネ制御の場合、設定温度と、最小の消費電力量となる圧縮機21(後述する)の回転数と、が紐付けされた状態で、設定温度を段階的に変更する。よって、空気調和システムは、余分に使われる消費電力量を削減する。したがって、空気調和システムは、空調装置1(後述する)の運転を開始してから室内温度が目標温度に到達するまでに使われる余分な消費電力量を削減する。この結果、空気調和システムは、空調装置1(後述する)の運転効率を高め、消費電力の少ない省エネルギー運転を行う。なお、本発明は、冷房又は暖房の消費電力量を抑えて起動制御する空気調和システムに好適である。
図1は、本発明の実施の形態1における空気調和システムの制御対象である空調装置1の概略構成の一例を示す図である。図1に示すように、空調装置1は、室外機11と、室内機13とを備えている。室外機11は、例えば、家屋3の外側に設けられている。室内機13は、例えば、家屋3の内側に設けられている。空調装置1は、室内空間71を空調対象としている。つまり、空調装置1は、室内空間71が空気の制御対象空間である。
例えば、運転モードとして、冷房運転が選択された場合、冷凍サイクルの動作は以下のようになる。圧縮機21から吐出された冷媒は、四方弁22を通過して室外熱交換器23に流れる。室外熱交換器23に流れた冷媒は、室外空間72から吸い込まれた室外空気と熱交換して凝縮液化し、膨張弁24に流れる。膨張弁24に流れた冷媒は、膨張弁24で減圧され、室内熱交換器25に流れる。室内熱交換器25に流れた冷媒は、室内空間71から吸い込まれた室内空気と熱交換して蒸発ガス化し、四方弁22を通過して圧縮機21に再び吸入される。このようにして冷媒が流れることで、室内空間71から吸い込まれた室内空気が室内熱交換器25で冷却される。室内熱交換器25における冷媒と室内空気との熱交換量は、冷却能力Qと呼ばれる。冷却能力Qは、圧縮機21の回転数を変えることで調整される。
例えば、運転モードとして、暖房運転が選択された場合、冷凍サイクルの動作は以下のようになる。圧縮機21から吐出された冷媒は、四方弁22を通過して室内熱交換器25に流れる。室内熱交換器25に流れた冷媒は、室内空間71から吸い込まれた室内空気と熱交換して凝縮液化し、膨張弁24に流れる。膨張弁24に流れた冷媒は、膨張弁24で減圧され、室外熱交換器23に流れる。室外熱交換器23に流れた冷媒は、室外空間72から吸い込まれた室外空気と熱交換して蒸発ガス化し、四方弁22を通過して圧縮機21に再び吸入される。このようにして冷媒が流れることで、室内空間71から吸い込まれた室内空気が室内熱交換器25で加熱される。室内熱交換器25における冷媒と室内空気との熱交換量は、加熱能力Qと呼ばれる。加熱能力Qは、圧縮機21の回転数を変えることで調整される。
次に、冷媒回路内の冷媒が流通することで生じる各種現象及び各種パラメータの変位について、図2~図4を用いて説明する。図2は、本発明の実施の形態1における圧縮機21の回転数を一定にして冷房運転した場合の室内温度及び室内熱交換器25の冷媒温度のそれぞれの経時変化の一例を示す図である。図2に示すように、冷房運転の場合、室内熱交換器25は、蒸発器として機能する。よって、冷媒の飽和温度は蒸発温度と呼ばれる。冷房運転の場合、運転開始時に冷房運転を開始して室内温度が低下すると、室内熱交換器25の周囲を通過する空気温度は下がる。したがって、室内熱交換器25内部の低温の冷媒は、蒸発ガス化しにくくなることで冷媒のガス量が減少するため、圧力及び蒸発温度が低下する。
空気調和システムは、運転モードとして、例えば、通常制御と、省エネ制御とを備えている。通常制御は、室内温度と、設定温度との差に応じて圧縮機21の回転数を制御する。省エネ制御は、通常制御と比べて消費電力量を削減させる。空気調和システムは、例えば、使用者で選択された省エネモードの入切で、通常制御と、省エネ制御との切り替えを行っている。空気調和システムは、省エネモードの入が選択された場合に省エネ制御に切り替え、省エネモードの切が選択された場合に通常制御に切り替える。例えば、使用者は、リモートコントローラー55を介して、省エネモードを選択した状態で、空調装置1の運転開始指令を室内機13に送信した場合、空調装置1は、省エネ制御で運転を行う。
通常制御部91は、通常制御を実行し、例えば、比例制御部101、積分制御部102、及び微分制御部103を備えている。通常制御部91は、省エネ制御が終了した旨を報知された場合又は使用者から直接指令が供給された場合、通常制御を開始する。運転モードが通常制御の場合、空調装置1は、室内温度として室内空間71の代表温度を検知する室内温度センサ41の計測値が、使用者で設定された設定温度となるように運転を実行する。
省エネ制御部92は、省エネ制御を実行し、例えば、図6で後述するように、第1演算部111、第2演算部113、第3演算部115、及び第4演算部119を備えている。また、例えば、図7で後述するように、第1演算部111、第2演算部113、第3演算部115、及び設定温度制御部121を備えていてもよい。省エネ制御部92は、省エネ制御が終了した場合、その旨を通常制御部91に報知する。
式(3)は、室内空間71、すなわち、部屋の熱容量Cと、空調装置1の能力Qと、家屋3の外壁を貫流する熱、換気に起因する熱、日射熱、照明235(後述する)又は人等の内部発熱を意味する熱負荷Dと、に基づいて、室内温度を1℃冷却又は加熱するために必要な時間間隔Δtを表す。
図6は、実施の形態1における圧縮機回転数の制御方法が通常制御と異なる場合の省エネ制御部92の機能ブロックの一例について示す図である。図6においては、例えば、室内機13又は室外機11に省エネ制御部92が組み込まれることが想定される。つまり、省エネ制御部92の出力が圧縮機回転数となる一例である。第1演算部111は、室内温度や室外温度や室内湿度などのセンサ値から運転効率COP特性のA及びBを求める。第2演算部113は、センサ値から熱負荷Dを求める。第3演算部115は、運転効率COP特性のA及びB、並びに熱負荷Dから能力Q0を求める。第4演算部119は、能力Q0とセンサ値と室内風量設定などから圧縮機回転数を求める。
省エネタイマー制御部93は、省エネタイマー制御を実行し、例えば、図5に示すように、第5演算部141、第6演算部142、第7演算部143、及び第8演算部144を備えている。第5演算部141は、使用者で設定された設定値又は過去の情報からの推定値に基づいて、在室情報を求める。在室情報は、例えば、使用者が在室を始める時刻、使用者が在室を続ける時間幅、及び使用者が不在となる時刻を含む。在室情報は、使用者で設定される場合、例えば、リモートコントローラー55が利用される。なお、使用者が在室情報を設定する機器は、リモートコントローラー55に限定されない。例えば、図1に示す計測制御装置51又は計測制御装置53であってもよい。また、図18で後述するHEMSコントローラー223、通信装置228、又は端末229であってもよい。
また、在室情報が過去の情報からの推定値で設定される場合、室内空間71に存在する各種機器、例えば、リモートコントローラー55等の過去の情報が用いられることで在室情報が推定され、推定された在室情報が設定されてもよい。具体的には、朝、昼、夕方、及び夜間等の特定の時間帯ごとに、使用者がリモートコントローラー55の操作を初めて行った時間をリモートコントローラー55又は空調装置1に記憶させておく。次に、空気調和システムは、そのようにして記憶させたリモートコントローラー55が使用された時間を収集し、収集した結果に基づいて、使用者が在室を始める時刻、すなわち、在室開始時間を推定し、推定した在室開始時間を設定する。なお、在室開始時間が複数得られる場合、空気調和システムは、例えば、平均値を求め、その平均値を在室開始時間に決定してもよい。
圧縮機21の回転数を適切に制御する一手法として、空調装置1の運転を開始してから室内温度が目標温度に到達するまでの合計の消費電力を大幅に削減させる動作原理について、図8~図10を用いて説明する。図8は、本発明の実施の形態1における圧縮機回転数の変動に伴う室内温度1℃変化に対応する時間間隔Δt及び時間間隔Δtあたりの消費電力量のそれぞれの変動を運転開始時と室内温度変化後とで比較した一例を示す図である。図8においては、中抜きの丸印が省エネ制御の動作点を意味するものとして説明する。
図9は、本発明の実施の形態1における空調装置1を圧縮機回転数の指令で省エネ制御を行った場合の室内温度の経時変化の一例を示す図である。図9は、暖房運転の場合の一例を示す。図9に示すように、空気調和システムは、運転開始時から室内温度変化後にかけて、圧縮機回転数をN1からN2にかけて制御すると、室内温度は、時間間隔Δt1及び時間間隔Δt2のそれぞれで、1℃の温度勾配で変化する。よって、最適な圧縮機回転数Nを指令することで、省エネ制御が実行される。
図10は、本発明の実施の形態1における空調装置1を設定温度の指令で省エネ制御を行った場合の圧縮機回転数の経時変化の一例を示す図である。図10は、暖房運転の場合の一例を示す。図10に示すように、空気調和システムは、運転開始時では設定温度を室内温度+1℃に設定し、時間間隔Δt1経過したら、設定温度を1℃増加する。そして、室内温度変化後では時間間隔Δt2経過したら設定温度を1℃増加する。このとき、空気調和システムは、圧縮機回転数を通常制御と同様に設定温度と室内温度との温度差に応じて制御すると、結果的にN1からN2に近い回転数で制御される。
次に、上記で説明した動作原理に基づいて、省エネ制御を行う動作について図11を用いて説明する。図11は、本発明の実施の形態1における空気調和システムの制御例のうち、省エネ制御処理の一例を説明するフローチャートである。
空気調和システムは、省エネ制御が選択された状態であるか否かを判定する。空気調和システムは、省エネ制御が選択された状態である場合、ステップS12に進む。一方、空気調和システムは、省エネ制御が選択された状態でない場合、ステップS21に進む。
空気調和システムは、温度に関連したデータを取得する。例えば、空気調和システムは、室内温度、外気温度、目標温度、及び在室開始温度等の空調情報を取得する。また、空気調和システムは、空調情報として、設定温度の刻み幅を取得する。
空気調和システムは、nに1を設定する。ここで、nは、複数の時間間隔Δtのうち、該当する時間間隔Δtを参照するために用いる添え字である。よって、nには1以外の値が設定されてもよい。要するに、複数の時間間隔Δtのうち、該当する時間間隔Δtを参照することができればよい。
空気調和システムは、何れの運転モードが選択されているかを判定する。空気調和システムは、運転モードが暖房である場合、ステップS15に進む。空気調和システムは、運転モードが冷房である場合、ステップS16に進む。空気調和システムは、運転モードがそれ以外の場合、ステップS21に進む。
空気調和システムは、室内温度に刻み幅を加算して設定温度とする。例えば、空気調和システムは、設定温度の刻み幅が1℃である場合、設定温度=室内温度+刻み幅℃=室内温度+1℃と設定する。
空気調和システムは、室内温度に刻み幅を減算して設定温度とする。例えば、空気調和システムは、設定温度の刻み幅が1℃である場合、設定温度=室内温度-刻み幅℃=室内温度-1℃と設定する。
空気調和システムは、空調装置1の運転を開始する。
空気調和システムは、時間間隔Δtnが経過したか否かを判定する。空気調和システムは、時間間隔Δtnが経過した場合、ステップS19に進む。一方、空気調和システムは、時間間隔Δtnが経過しない場合、ステップS18に戻る。
空気調和システムは、nに1を加算する。例えば、空気調和システムは、nを+1歩進するために、n=n+1と設定する。
空気調和システムは、設定温度が目標温度に到達したか否かを判定する。空気調和システムは、設定温度が目標温度に到達した場合、ステップS21に進む。一方、空気調和システムは、設定温度が目標温度に到達しない場合、ステップS14に戻る。
空気調和システムは、通常制御を実行し、処理を終了する。なお、通常制御は、上記で説明したように、比例制御、積分制御、及び微分制御の何れか又はその組み合わせである。
次に、省エネ制御を実行させるタイミングの制御例について、図12を用いて説明する。図12は、本発明の実施の形態1における空気調和システムの制御例のうち、省エネタイマー制御処理の一例を説明するフローチャートである。
空気調和システムは、在室情報を取得する。
空気調和システムは、在室情報に基づいて在室開始時刻を求める。
空気調和システムは、空調情報を取得する。
空気調和システムは、空調情報に基づいて設定温度ごとの時間間隔Δtを求める。
空気調和システムは、時間間隔Δtの合計時間を求める。
空気調和システムは、在室開始時刻から時間間隔Δtの合計時間を差し引いて予冷予暖開始時刻を決定する。
空気調和システムは、予冷予暖開始時刻であるか否かを判定する。空気調和システムは、予冷予暖開始時刻である場合、ステップS48に進む。一方、空気調和システムは、予冷予暖開始時刻でない場合、ステップS47に戻る。
空気調和システムは、省エネ制御処理を実行する。具体的には、上記で説明したステップS11~ステップS20の処理を実行する。
空気調和システムは、通常制御処理を実行する。具体的には、上記で説明したステップS21の処理を実行し、処理を終了する。
次に、図1で説明した空調装置1に各種センサを追加した一例について図13を用いて説明する。図13は、本発明の実施の形態1における空調装置1の概略構成の別の一例を示す図である。図13に示すように、室内機13に赤外線センサ43が設けられ、室内空間71に人感センサ44が設けられている。赤外線センサ43は、放射温度等のような物体の放射エネルギーを検知する。よって、赤外線センサ43は、室内空間71に存在する躯体の温度を検知することができる。したがって、赤外線センサ43の検知結果を空調装置1の制御に用いる各種パラメータのうちの一つである室内温度に利用することができる。なお、赤外線センサ43は、本発明における第1センサに相当する。
図14においては、図5で示した空調装置制御モジュール90と比べ、例えば、温度範囲補正テーブルが追加され、省エネ制御部92に設定温度制限指令が供給される点が相違する。温度範囲補正テーブルは、設定温度の範囲と、制限をかけた目標温度とが紐付けされたものである。省エネ制御部92は、設定温度制限指令が供給された場合、温度範囲補正テーブルを参照し、設定温度に対応する目標温度に制限をかける。
図15において、図5で示した空調装置制御モジュール90と比べ、例えば、使用電流範囲補正テーブルが追加され、省エネ制御部92に電流制限指令が供給される点が相違する。使用電流範囲補正テーブルは、使用電流の範囲と、制限をかけた使用電流の範囲とが紐付けされたものである。省エネ制御部92は、電流制限指令が供給された場合、使用電流範囲補正テーブルを参照し、使用電流に制限をかける。
次に、省エネ制御を時限制御する場合に、外部に許可を求める一例について、図16を用いて説明する。図16は、本発明の実施の形態1における省エネタイマー制御の許可判定を実行して空調装置1を制御する空調装置制御モジュール90の機能ブロックの一例を示す図である。図16においては、図5で示した空調装置制御モジュール90と比べ、省エネタイマー制御部93の第8演算部144から外部に許可判定要求又は運転開始通知が供給される点が相違する。
次に、省エネ制御を時限制御する場合に、人の存否判定結果に応じて、制御内容を変更する一例について図17を用いて説明する。図17は、本発明の実施の形態1における室内空間71での人の存否判定結果に基づいて空調装置1を制御する空調装置制御モジュール90の機能ブロックの一例を示す図である。図17においては、図5で示した空調装置制御モジュール90と比べ、省エネタイマー制御部93の第8演算部144に、人の存否に関するデータである存否判定データが供給されたり、省エネタイマー制御部93の第8演算部144から空調装置1に空調停止命令が供給されたり、省エネタイマー制御部93の第8演算部144から省エネ制御部92に設定温度変更指令が供給されたりする点が相違する。
上記の構成で、空気調和システムは、省エネ制御の場合、設定温度と、最小の消費電力となる圧縮機21の回転数と、を紐付けした状態で、設定温度を段階的に変更することができる。よって、空気調和システムは、余分に使われる消費電力量を削減する。したがって、空気調和システムは、空調装置1の運転を開始してから室内温度が目標温度に到達するまでに使われる余分な消費電力量を削減することができる。この結果、空気調和システムは、空調装置1の運転効率を高めることで、消費電力の少ない省エネルギー運転を行うことができる。
実施の形態1との相違点は、HEMSを空気調和システムの制御対象とする点である。具体的には、実施の形態1では、空調装置制御モジュール90は、空調装置1を制御対象としていた。そこで、実施の形態2では、空調装置制御モジュール90は、空調装置1の他に、HEMSを制御対象に加える。よって、実施の形態2では、HEMSの制御と、空調装置制御モジュール90の制御とが連係して行われることで、余分に使われる消費電力量をさらに削減する。まず、実施の形態2におけるHEMSについて説明する。図18は、本発明の実施の形態2における空気調和システムの制御対象であるHEMSの概略構成の一例を示す図である。
図18に示すように、HEMSは、図1に示す家屋3には、空調装置1の室内機13、端末229、IHクッキングヒーター231、レンジグリル233、及び照明235等の家電機器である電気機器が設けられている。また、HEMSは、図1に示す家屋3の屋外には、蓄電池241を搭載した電気自動車211、パワーコンディショナー213、太陽電池アレイ215、分電盤219、及び電力計測器221等の電気機器が設けられている。各電気機器は、電源線251で接続されている。また、電気機器のうち、家電機器は、電力会社217から供給される電力、太陽電池アレイ215から供給される電力、又は電気自動車211に搭載された蓄電池241から供給される電力で駆動し、電力計測器221で消費電力が測定される。
遠隔から通信装置228を用いることで、空調装置1の省エネ制御を実行する一例について説明する。使用者は、携帯電話、スマートフォン、タブレット、パソコン、又はカーナビ等の通信装置228を所有していると想定する。また、家屋3の内側である宅内又は家屋3の外側である宅外の何れかに存在する通信装置228が、公衆回線227を介して各種データをHEMSコントローラー223へ向けて送信したと想定する。
なお、HEMSに空調装置1が複数台ある場合を想定すると、通信装置228から空調装置1の操作指令をするときに、複数台の空調装置1のうち、どの空調装置1を操作対象とするかを選択する必要がある。例えば、通信装置228の操作指令用のアプリケーションに空調装置1を選択するボタン又は選択画面等を表示させてもよい。この場合、1度選択された空調装置1が記憶され、次回操作時には自動的に記憶された空調装置1が操作対象となるようにしてもよい。また、通信装置228ごとに、操作対象となる空調装置1を予め固定登録してもよい。また、通信装置228と、空調装置1との組み合わせ情報は、HEMSコントローラー223で記憶させてもよく、通信装置228で記憶させてもよい。
空気調和システムは、運転指令があるか否かを判定する。空気調和システムは、運転指令がある場合、ステップS62に進む。一方、空気調和システムは、運転指令がない場合、ステップS61に戻る。
空気調和システムは、各種フラグを読み込む。例えば、距離フラグは、運転指令の送信元と、運転指令の送信先との距離が閾値距離内であるか否かを判定する動作をするか否かを規定するものと想定する。また、時間フラグは、予想到着時間が閾値時間内であるか否かを判定する動作をするか否かを規定するものと想定する。
空気調和システムは、距離フラグが1であるか否かを判定する。空気調和システムは、距離フラグが1である場合、ステップS64に進む。一方、空気調和システムは、距離フラグが1でない場合、ステップS65に進む。
空気調和システムは、運転指令の送信元と運転指令の送信先である家との距離が閾値距離内であるか否かを判定する。空気調和システムは、運転指令の送信元と運転指令の送信先である家との距離が閾値距離内である場合、ステップS67に進む。一方、空気調和システムは、運転指令の送信元と運転指令の送信先である家との距離が閾値距離内でない場合、処理を終了する。
空気調和システムは、時間フラグが1であるか否かを判定する。空気調和システムは、時間フラグが1である場合、ステップS66に進む。一方、空気調和システムは、時間フラグが1でない場合、処理を終了する。
空気調和システムは、予想到着時間が閾値時間内であるか否かを判定する。空気調和システムは、予想到着時間が閾値時間内である場合、ステップS67に進む。一方、空気調和システムは、予想到着時間が閾値時間内でない場合、処理を終了する。
空気調和システムは、省エネ制御処理を実行し、処理を終了する。なお、省エネ制御処理は、図11で説明したステップS11~ステップS20の処理に相当する。
空気調和システムは、運転指令があるか否かを判定する。空気調和システムは、運転指令がある場合、ステップS82に進む。一方、空気調和システムは、運転指令がない場合、ステップS81に戻る。
空気調和システムは、運転指令に含まれる識別コードから該当する使用者を特定する。識別コードは、例えば、通信装置228が携帯電話であると想定すると、SIM(Subscriber Identity Module)カードに記憶されている固有のID番号を用いればよい。なお、識別コードは特に限定されない。
空気調和システムは、該当する使用者に対応する生活パターンデータを取得する。
空気調和システムは、取得した生活パターンデータに対応する空調装置1を特定する。
空気調和システムは、該当する使用者の帰宅を検知したか否かを判定する。空気調和システムは、該当する使用者の帰宅を検知した場合、ステップS86に進む。一方、空気調和システムは、該当する使用者の帰宅を検知しない場合、ステップS85に戻る。
空気調和システムは、取得した生活パターンに基づいて取得した生活パターンに対応する空調装置1を制御し、処理を終了する。
上記の説明から、HEMSは、空調装置1の省エネ制御を他の家電機器が多く使われる時間帯を避けて実施することで、家庭全体の消費電力のピークを下げて平準化でき、社会的な電力不足の要請にも節電で貢献することができる。また、HEMSは、家屋3に設置された太陽電池アレイ215又は蓄電池241の電力を家電機器に供給する場合も電力の平準化で効率良く電力を使用することができる。
実施の形態1及び実施の形態2では、空気調和システムの構成例及び動作例について説明した。実施の形態3においては、空気調和システムの実装形態例について、図22を用いて説明する。
