御方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an operation control method for controlling the capacity of an air conditioner.

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
を行なつていた。Conventional configuration and its problems Conventionally, heat pump air conditioners that use a variable capacity compressor to change heating capacity,
As a condition for changing the capacity, the indoor temperature is detected, and as shown in FIG. 1, the capacity level is set based on the difference between the room temperature set value and the indoor temperature, and the capacity is changed according to 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℃に到達すると、一段回
転数の低いF3で運転し、さらに室温が上昇し設
定値に到達したら、もう一度低い回転数F2で運
転し、さらに室温が上昇して、設定値＋t2℃に到
達すると、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 ℃, it is operated at a lower rotational speed of one step, F3 . When the room temperature rises further and reaches the set value, it is operated again at a lower rotation speed F 2 , and when the room temperature rises further and reaches the set value + t 2 °C, it is operated at the lowest rotation speed F 1 .

そして、それぞれの回転数で運転しているとき
に、室温が下降した場合、室温が上昇していつた
時の回転数変化温度より一段低い温度で回転数を
１段づつ上げて行なう。すなわち、設定温度で

低回転数F1でもさらに室温が上昇した場合、設
定温度＋t1℃で圧縮機を停止し、室温が設定値ま
で下がつた時、圧縮機を再びF2の回転数で運転
する。 If the room temperature drops while operating at each rotation speed, the rotation speed is increased one step at a time at a temperature one step lower than the rotation speed change temperature when the room temperature rises. In other words, at the set temperature
F 1 → F 2 , set temperature - t 3 ℃ F 2 → F 3 , set temperature - t 4
At ℃, increase the rotation speed from F 3 to F 4 . Furthermore, if the room temperature rises further even at the minimum rotation speed F 1 , the compressor is stopped at the set temperature + t 1 °C, and when the room temperature falls to the set value, the compressor is operated again at the rotation speed F 2 .

このような制御を行なつた時、圧縮機は停止せ
ず、F1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。 When such control is performed, the rotation speed is set so that the compressor does not stop and operates almost continuously at F1 .

この場合、室温が設定値＋t1℃に近づくにした
がい圧縮機能力を下げて暖房能力を下げ、負荷に
合つ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
風感を与え、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。 In this case, as the room temperature approaches the set value + t 1 °C, the compression function is lowered to lower the heating capacity, and heating is performed in accordance with the load. It has the disadvantage that it gives a feeling of cold air to the human body and such operation becomes stable and continues for a long time.

た。 In addition, some devices detect the temperature of the air outlet and, when the temperature drops, change the direction of the air outlet to prevent the air from entering the living space and to prevent the feeling of cold air. This mainly targets when the compressor is stopped due to the thermostat and when the blowing temperature is low at startup.If the compressor does not blow into the living space during stable operation, the indoor temperature distribution will deteriorate. Therefore, things that can reduce the compression function include:
On the contrary, it worsened comfort and air conditioning efficiency.

The first set value T 1 and the second
When the temperature is between the second set value T 2 , the compression capacity is brought closer to the compression capacity determined by the room temperature by at least one step, and when the outlet temperature is below the second set value T 2 , the compression capacity is reduced by at least one step. control to increase the temperature and maintain the blowout temperature in the vicinity of the first set value T1 and the second set value T2 ,
This prevents the blowout temperature from decreasing.

The operating frequency is determined by comparison with the frequency allocation shown in FIG. 3, and an address signal of the operating frequency is output to the programmable counter 6. The programmable counter 6 divides the reference frequency signal output from the oscillator 7 according to the address signal output from the CPU 5, and outputs an operating frequency signal to the inverter controller 8. The inverter controller 8 outputs a waveform control signal for the inverter 9 based on the operating frequency signal from the programmable counter 6. The inverter 9 is
The AC power input is once converted to DC, and according to the control signal from the inverter controller 8, the DC power is sent to the compressor motor 10 as an AC power at the operating frequency to operate the compressor (not shown).

切換える。 In the same figure, Ts is the room temperature setting value set by the thermostat, and boundary lines are set at +1℃, +2℃, -1℃, and -2℃. When the room temperature rises, the operation is initially at 75Hz, and when Ts exceeds -1℃, Switch to 60Hz, switch to 45Hz when it exceeds Ts℃, and switch to 30Hz when it exceeds Ts+1℃.

さらに温度が上昇し、Ts＋２℃を越えたら圧
縮機を停止する。圧縮機が停止して復帰する場合
は、室温がTs℃を下回つたときで、45Hzで運転
を始める。 If the temperature rises further and exceeds Ts + 2°C, the compressor will be stopped. When the compressor stops and restarts, it starts operating at 45Hz when the room temperature drops below Ts℃.

When operating at Hz, 30 until it drops to Ts℃
Hz, and when the temperature drops below Ts℃, it becomes 45Hz. If the temperature drops while operating at 45Hz, when the temperature drops below Ts-1℃, it changes to 60Hz, and when going from 60Hz to 75Hz, it changes to Ts-2℃. It is set to trigger when the temperature drops below .

温度コントロールを行う範囲としている。 Also, the temperature range in the shaded area, that is, the room temperature
If the temperature is between Ts℃ and Ts+2℃, it is within the range where the temperature of the air outlet is controlled.

第４図は、吹き出し温度コントロールを行なう
ときの周波数の変更の割り振りを示している。 FIG. 4 shows the allocation of frequency changes when controlling the temperature of the air outlet.

てある。 In other words, when the air outlet temperature is between 40°C and 52°C, if the currently operating frequency is different from the frequency based on room temperature in Figure 3, it should be brought closer to the frequency based on room temperature at 15Hz, and the air outlet temperature will be 52℃
The setting is to lower the 15Hz frequency when the temperature exceeds 40℃, and increase the 15Hz frequency when the temperature is lower than 40℃.

次に、第５図のタイミングチヤートにより、本
実施例の制御方法の動作を説明する。 Next, the operation of the control method of this embodiment will be explained using the timing chart shown in FIG.

出し温度は、40℃と52℃の間にあるので、そのま
まの周波数45Hzで運転を続ける。 Starts at time t 0 , then the room temperature is Ts−1
Since it is as follows, the room temperature is controlled by operating at 75Hz with frequency allocation only for the room temperature as shown in Figure 3. The blowout temperature gradually rises from around room temperature and remains stable at over 52℃. At time t1 , the room temperature reaches Ts-1, the operation changes to 60Hz, and the outlet temperature stabilizes and falls between 40°C and 52°C. The room temperature further increases and reaches Ts at time t2 . At this time, at the same time as starting 45Hz operation by room temperature control as shown in Figure 2,
The blowout temperature control is started, and the blowout temperature is detected by the blowout temperature sensor 3. At this time, the blowout temperature is between 40℃ and 52℃, so operation continues at the same frequency of 45Hz.

そしてt2よりΔtだけ時間が経過した時間t3に、
吹き出した温度を検出する。この時も、吹き出し
温度が40℃と52℃の間にあるのでそのまま45Hz運
転を続け、さらにΔt経過後、時間t4に吹き出し温
度を検出する。この時も、吹き出し温度は40℃と
52℃の間にあるので、そのまま45Hz運転を続け
る。 Then, at time t 3 , when Δt has passed since t 2 ,
Detects the temperature of the blown air. At this time as well, since the blowout temperature is between 40° C. and 52°C, the 45Hz operation continues, and after Δt has elapsed, the blowout temperature is detected at time t4 . At this time, the temperature of the air outlet was 40℃.
Since the temperature is between 52℃, 45Hz operation continues.

次に、時間t5で室温がTs＋１を越えると、室
温制御により30Hz運転となる。 Next, when the room temperature exceeds Ts+1 at time t5 , the room temperature is controlled to operate at 30Hz.

次にt4よりΔt経過後のt6で吹き出し温度を検出
する。この時は、吹き出し温度が、40℃以下に下
がつているため、第４図に示す吹き出し温度制御
による周波数補正、すなわち吹き出し温度制御が
始まり、運転周波数を＋15Hz上げ45Hz運転とす
る。 Next, the blowout temperature is detected at t 6 after Δt has elapsed from t 4 . At this time, since the blowout temperature has fallen below 40°C, frequency correction by blowout temperature control shown in FIG. 4, that is, blowout temperature control, is started, and the operating frequency is increased by +15Hz to 45Hz operation.

次にt6よりΔt後t7で吹き出し温度を検出する。
この時は、吹き出し温度が40℃と52℃の間にある
ので、周波数補正を行なう。 Next, the blowout temperature is detected at t7 after Δt from t6 .
At this time, the blowout temperature is between 40°C and 52°C, so frequency correction is performed.

すなわち、第３図による室温制御では30Hzの周
波数運転の指示であり、現在の運転周波数が45Hz
であるので、15Hzだけ30Hzに近づける周波数補正
を行ない、30Hz運転とする。 In other words, the room temperature control shown in Figure 3 is an instruction to operate at a frequency of 30Hz, and the current operating frequency is 45Hz.
Therefore, the frequency is corrected to bring it closer to 30Hz by 15Hz, resulting in 30Hz operation.

さらに、t7よりΔt経過後t8に吹き出し温度を検
出し、t6と同様の状態であるため、45Hz運転とな
り、以後t6とt7の繰り返し状態が続き、吹き出し
温度は、40℃近辺で安定し、第５図の点線で示す
吹き出し温度制御を行なわない場合のような吹き
出し温度が極端に低下することがさけられる。 Furthermore, the air outlet temperature is detected at t 8 after Δt has elapsed from t 7 , and since it is in the same state as t 6 , it becomes 45Hz operation, and after that, the state of repeating t 6 and t 7 continues, and the air outlet temperature is around 40℃. It is possible to avoid the extreme drop in the temperature of the air outlet, which occurs when the air outlet temperature control shown by the dotted line in FIG. 5 is not carried out.

また室温制御の周波数へ戻すことにより周波数
を高めたままでの連続運転が避けられるため、室
温が上り過ぎ圧縮機を停止する機会を減らすこと
ができ、圧縮機停止による一時的な吹き出し温度
の低下も避けることができる。 In addition, by returning to the room temperature control frequency, continuous operation with a high frequency can be avoided, reducing the chances of stopping the compressor when the room temperature rises too much, and also reducing the chance of a temporary drop in the blowout temperature due to the compressor stopping. It can be avoided.

様の効果が得られる。 In addition, in this embodiment, a method using frequency change using an inverter was explained as a means for varying the capacity of the compressor, but it is also possible to use a method that controls the compressor rotation speed by changing the number of poles of the compressor motor, or A similar effect can be obtained by changing the number of operating compression chambers in a compressor having a plurality of compression chambers, or by changing the amount of refrigerant circulation by performing a bypass.

It is clear that the effect will be even better if the time interval is different.

る。Effects of the Invention As is clear from the above embodiments, the present invention has a variable capacity compressor, a detection means for detecting room temperature, and a detection means for detecting outlet temperature, and has an operational compression function determined by the room temperature. The temperature of the outlet is periodically detected in response to the force, and a set temperature is set for the outlet temperature such that the first set value T 1 > the second set value T 2 .
When the detected air outlet temperature is equal to or higher than the first set value T1 , the compression function is reduced by at least one stage, and the air outlet temperature is between the first set value T1 and the second set value T2 . When the temperature is between the two, the compression function is controlled to approach the compression function determined by the room temperature by at least one step, and when the blowout temperature is below the second set value T2 , the compression capacity is increased by at least one step. This function corrects the air outlet temperature to keep it close to the first set value T1 and the second set value T2 , preventing continuous operation with the air outlet temperature decreasing, and It is possible to provide comfortable heating without causing any discomfort.
Further, in the case where the direction of the air blowing air is changed according to the air blowing temperature, it is possible to prevent the air conditioning efficiency from decreasing due to not blowing air into the living space.
