本発明は空気調和機の能力制御を行う運転制御方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an operation control method for controlling the capacity of an air conditioner.
従来例の構成とその問題点
従来、能力可変型の圧縮機を用い、暖房能力を変化させ
るヒートポンプ式空気調和機において、能力変更する条
件として室内の温度を検出し、第１図に示すように室温
設定値と室内温度との差により能力段位を設定し、室温
により能力変化を行なっていた。Conventional configuration and its problems Conventionally, in a heat pump air conditioner that uses a variable capacity compressor to change the heating capacity, the indoor temperature is detected as a condition for changing the capacity, and as shown in Figure 1. Capacity levels were set based on the difference between the room temperature set point and the room temperature, and the capacity was changed based on the room temperature.
すなわち、圧縮機の回転数を変化して能力可変を行なう
ものでは、最初高回転Ｆ４で運転し、室温が上昇して設
定値−ｔ３°Ｃに到達すると、一段回転数の低いＦ３で
運転し、さらに室温が上列し設定値に到達したら、工う
一段低い回転数Ｆ２で運転し、さらに室温が上昇して設
定値」−１２°Ｃに到達するき、最低回転数Ｆ１ で運
転する。In other words, in a compressor whose capacity is varied by changing the rotational speed of the compressor, it is first operated at a high rotational speed F4, and when the room temperature rises and reaches the set value -t3°C, it is operated at a lower rotational speed of one step, F3. When the room temperature rises further and reaches the set value, it operates at a lower rotation speed F2, and when the room temperature rises further and reaches the set value -12°C, it operates at the lowest rotation speed F1.
そしてそれぞれの回転数で運転しているときに、室温が

なわち、設定温度でＦｌ−Ｆ２゜設定温度−１３°Ｃで
Ｆ２−Ｆ３．設定温度−ｔ４°ＣでＦ３−Ｆ４と、回転
数を上げて行く。If the room temperature drops while operating at each rotation speed, the rotation speed is increased one step at a time at the discharge temperature from the temperature at which the rotation speed changes when the room temperature rises. That is, at the set temperature, Fl-F2°, and at the set temperature of -13°C, F2-F3. At the set temperature -t4°C, increase the rotation speed to F3-F4.
オ／こ、最低回転数Ｆ１ でもさらに室温が」二列し
た場合、設定流度〜ｔ１°Ｃで圧縮機を停止し、室温が
設定値まで丁かった時、圧縮機を再びＦ２の回転数で運
転する。O/This, if the room temperature becomes even higher than the minimum rotation speed F1, stop the compressor at the set flow rate ~ t1°C, and when the room temperature reaches the set value, turn the compressor back on to the rotation speed F2. drive with
このような制御を行なった時、圧縮機は停止せず、Ｆｌ
でほとんど連続運転となるように回転数は設定されて
いる。この場合、室温が設定値＋ｔ。When such control is performed, the compressor does not stop and the Fl
The rotation speed is set so that almost continuous operation occurs. In this case, the room temperature is set value +t.

下げ、負荷に合った暖房を行なうものであるが、圧縮機
能力を下げると吹き出し温度が低下するので、人体に冷
風感を力え、そのような運転が安定状態となり長時間続
く欠点を有していた。As the temperature approaches °C, the compressor function is lowered to lower the heating capacity, and heating is performed in accordance with the load. However, when the compression function is lowered, the blowout temperature decreases, which gives the human body a feeling of cold air. Such operation has a drawback that it becomes stable and continues for a long time.
また吹き出し温度が下がると、冷風感を与えないだめに
吹き出し風が居住空間へ入らないように吹き出し温度に
より、吹き出し方向を変更しているものにおいては、吹
き出し温度が低いことから居住空間への吹き出しを行な
わないため、空調効率が非常に悪くなる欠点があった。In addition, when the temperature of the air outlet decreases, the direction of the air outlet is changed depending on the temperature of the air outlet so that the air does not enter the living space without giving a feeling of cold air. Since this system does not perform air conditioning, there is a drawback that air conditioning efficiency is extremely poor.

ようにし、吹き出し温度が下降し第２の設定値Ｔ２を下
回った場合は、現在の運転能力より１段高い能力で運転
するようにしたものである。Structure of the Invention In order to achieve this object, the present invention provides a set temperature for the air outlet temperature such that the first set value T1>the second set value T2, and when the room temperature falls within the set temperature range, the air outlet temperature is detected. However, if the outlet temperature rises and exceeds the first set value T1, the operation is made to operate at a capacity one step lower than the current operating capacity, and if the outlet temperature decreases and falls below the second set value T2. , the vehicle is operated at a level one step higher than the current operating capacity.
これにより、吹き出し温度を第１の設定値Ｔ１と第２の
設定値Ｔ２の間に保つように制御を行ない、吹き出し温

ー３により吹き出し温度を検出しはじめる。In the figure, time t. When I started, the room temperature was T.
Since it is less than s-1, the room temperature is controlled by operating at 76 Hz with frequency allocation only for room temperature according to FIG. The blowout temperature gradually rises from around room temperature and remains stable above 52°C. Then, at time t1, the room temperature becomes T s-
1, the operation changes to 6oHz, and the blowout temperature becomes 1.
．． The temperature has fallen steadily and is between 40°C and 62°C. The room temperature further increases and reaches Ts at time t2. At this time, the air outlet temperature control is started at the same time as the room temperature control shown in FIG. 2 enters the 45 Hz operation, and the air outlet temperature sensor 3 begins to detect the air outlet temperature.

。In this case, since the blowout temperature is between 40°C and 52°C, operation continues at the same frequency of 45 Hz. The room temperature further rises during the 45 Hz operation, and at time t3, when the room temperature exceeds Ts+1, the room temperature control changes to the 3o Hz operation, and the blowout temperature begins to decrease. When the blowout temperature falls below 40° C. at time t4, the blowout temperature control is performed by increasing the operating frequency by 15 Hz to 45 Hz operation by frequency correction based on the blowout temperature shown in FIG. After the 45 Hz operation, the room temperature continues to rise gradually until time t5.
When the room temperature reaches Ts+2, the compressor is stopped by the room temperature control shown in FIG. 2, and the blowout temperature control is also canceled.

運転を行う。After the compressor stops, the room temperature drops and at time t6, the room temperature reaches Ts.
When the pressure drops to 100%, the compressor resumes operation. At this time, the operating frequency is 4ts Hz due to the room temperature control shown in Figure 2.
Drive.

同様の動作をくり返す。この時ｔ５からｔ、３の間の時
間は３〜５分程度である。Then, when the room temperature starts to rise during the 45H2 operation and exceeds Ts again, the blowout temperature control is started, and the same operation as after time t2 is repeated thereafter. At this time, the time from t5 to t, 3 is about 3 to 5 minutes.

Stable operation can be achieved for a long time at temperatures below C.
したがって本実施例では、吹き出し温度制御を行うこと
によって吹き出し温度が低い状態で長時間運転すること
を避け、圧縮機停止中の３〜６分程度に短縮できる。Therefore, in this embodiment, by controlling the blowout temperature, it is possible to avoid operating for a long time in a state where the blowout temperature is low, and to shorten the operation time to about 3 to 6 minutes while the compressor is stopped.
