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、能力可変形の圧縮機を用い、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. The capacity level was set based on the difference between the room temperature set value and the room temperature, and the capacity was changed depending 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−１３℃に到達すると、一段回転数の低いＴ５で運
転し、さらに室温が上昇し設定値さらに室温が上昇して
設定値−トｔ２℃に到達すると最低回転数２１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 high rotational speed F4, and when the room temperature rises and reaches the set value of -13°C, it is operated at one step lower rotational speed T5, The room temperature further rises to the set value, and when the room temperature further rises and reaches the set value -t2°C, the engine is operated at the minimum rotation speed of 21.
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、室温が上昇していった時の回転数変化
温度より一段低い温度で回転数を１段づつ上げて行う。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.
すなわち、設定温度でＦ１→Ｆ２．設定温度−ｔ３℃で
Ｆ２→Ｆ３．設定温度−ｔ４℃でＦ３→Ｆ４と回転数を
上げて行く。また、最低回転数Ｆ１でもさらに室温が上
昇した場合、設定温度＋１１℃で圧縮機を停市し、室温
が設定値まで下がった時、圧縮機を再びＦ２の回転数で
運転する。That is, at the set temperature, F1→F2. F2 → F3 at set temperature -t3℃. At the set temperature -t4℃, increase the rotation speed from F3 to F4. If the room temperature further rises even at the lowest rotation speed F1, the compressor is stopped at the set temperature +11° C., and when the room temperature falls to the set value, the compressor is operated again at the rotation speed F2.
このような制御を行なった時、圧縮機は停止せず、Ｆ＋
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

い圧縮機能力を下げて暖房能力を下げ、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。When such control is performed, the compressor does not stop and F+
The rotation speed is set so that almost continuous operation occurs. In this case, as the room temperature approaches the set value + t1°C, the compression 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 air outlet temperature decreases, which is harmful to the human body. It has the disadvantage that it gives a feeling of cold air and that such operation becomes stable and continues for a long time.
また、吹き出し温度を検出し、吹き出し温度が低下する
と、吹き出し風が居住空間に入るのを防市し、冷風感を
感じさせないように吹き出し風の方向を変更しているも
のもあるが、この場合は、サーモスタットによる圧縮機

時を主に対象としており、圧縮機の安定運転中に居住空
間への吹き出しを行なわない場合、室内温度分布が悪化
するので、圧縮機能力を低下できるものにはかえって快
適性を悪くシ、空調効率を悪化させていた。In addition, some devices detect the temperature of the air outlet and, when the temperature drops, prevent the air from entering the living space and change the direction of the air outlet so that the person does not feel cold. This mainly targets when the compressor is stopped by the thermostat and when the air temperature is low when starting up.If air is not blown into the living space while the compressor is operating stably, the indoor temperature distribution will change. Therefore, if the compression function can be lowered, the comfort will be worsened and the air conditioning efficiency will be deteriorated.

停止する。圧縮機が停止１７て復帰する場合は、室温が
Ｔｓ″Ｃを下回ったときで、４５Ｈｚで運転を始める。That is, TS is the room temperature setting value set by the thermostat, boundary lines are set at -1℃, 4-2℃, -1℃, -2℃, and when the room temperature rises, the operation is initially at 75H7, and Ts-1℃
If it exceeds TS'C, it becomes 60Hz, and if it exceeds TS'C, it becomes 45H2, T! When the temperature exceeds 9+1℃, switch to 30Hz. When the temperature rises further and exceeds Ts+2°C, the compressor is stopped. When the compressor stops 17 and returns, it starts operating at 45 Hz when the room temperature falls below Ts''C.

る時はＴｓ −２°Ｃを下回ったときと設定している。If the room temperature drops while still operating at each frequency, if it was operating at 30H2, it will continue to operate at 30Hz until it drops to Ts'C.
When TsC is turned on once, set it to 46Hz, and if the temperature drops while operating at 46H2, set it to 60Hz when it falls below Ts-1'G, and when changing from e□Hz to 45)iz, set Ts to 46Hz. It is set as when the temperature drops below -2°C.

出し風は、吹き出し温度が３７°Ｃ以下にあるときは１
上向きとなり、３７℃以下になると下向きとなる。In other words, when the air outlet temperature is between 40°C and 62°C, if the currently operating frequency is different from the frequency based on the room temperature in Figure 3, it should be brought closer to the frequency based on the room temperature of 15Hz, and the air outlet temperature is 52°C. The setting is such that the 15Hz frequency is lowered when the temperature exceeds 40°C, and the 15Hz frequency is increased when the temperature is lower than 40°C. Still blowing air is 1 when the blowing temperature is below 37°C.
It turns upward, and when the temperature drops below 37°C, it turns downward.
次に、第６図のタイミングチャートにより、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 with reference to the timing chart of FIG.

し温度も上昇を続ける。In the figure, the operation starts at time to, and since the room temperature is below Ts-1 at that time, the room temperature is controlled by operating at 75 Hz with frequency allocation only for the room temperature according to FIG. Since the temperature of the air outlet is not higher than the room temperature of 37°C, the direction of the air outlet is horizontal. The blowing temperature gradually rises from around room temperature and exceeds 37° C. at tl. At this time, the direction of the blowing air changes from horizontal to downward, sending warm air into the living space. The frequency remains at 75 Hz, and the room temperature and outlet temperature continue to rise.

At this time, if the blowout temperature is 40° C. or higher, the blowout temperature control causes the operating frequency to be 15H2 closer to the frequency of 30Hz under room temperature control than the current frequency of 4ts Hz, resulting in a 3oHz operation.
