This means air volume control. A conventional device of this type will be described with reference to FIG. ■ is the air conditioner's air intake port 2
It has a heat exchanger 8 and a blower 4, and the conditioned air is sent to an air-conditioned space (indoor) 6 through an air duct 5. Reference numeral 7 denotes a VAV damper provided before the air duct 5 opens into the air-conditioned space 6, and the degree of opening/closing thereof is controlled by the VAV controller 8. Reference numeral 9 represents a temperature sensor that detects the indoor temperature, and reference numeral 10 represents a manual switching device for heating and cooling modes.
ＶＡＶコントローラ８は温度センサ９の検出する室内温
度Ｔを、あらかじめ設定された冷暖房の基準温度Ｓと比
較して空調用空気の空調空間６に供給される量を、ＶＡ
Ｖダンパ７の開閉度を制御することによって調整する。The VAV controller 8 compares the indoor temperature T detected by the temperature sensor 9 with a preset reference temperature S for air conditioning and heating, and determines the amount of air conditioned air supplied to the air conditioned space 6 based on the VA.
Adjustment is made by controlling the opening/closing degree of the V damper 7.
暖房モードにおいて、ＶＡＶダンパ７は、Ｔ＜８ のと
きは開方向に、Ｔ＞８のときは閉方向に動作する。冷房
モードの場合は、ＶＡＶ汐゛ンパワ打Ｌ′しイＳめシ式
は閉方向に、Ｔ＞Ｓのときは開方向に動作する０かくし
て室内温度Ｔは基準温度Ｓに次第に近づき、Ｔ＝８のと
きはＶＡＶ ダンパ７は閉じ、空調用空気の供給は停止
される。In the heating mode, the VAV damper 7 operates in the opening direction when T<8 and in the closing direction when T>8. In the case of cooling mode, the VAV power stroke L' operates in the closing direction, and when T>S, it operates in the opening direction.Thus, the indoor temperature T gradually approaches the reference temperature S, and T= 8, the VAV damper 7 is closed and the supply of air conditioning air is stopped.
一方、空調機ｌにおいて調整された空調用空気は冬期の
暖房運転時は温風であシ、また夏期の冷房運転時は冷風
である。したがって暖房モードにおいて、ＶＡＶダンパ
７は、ＴくＳのときはＴ＝８になる迄温風を供給し、Ｔ
＞８のときはＴ＝８になるまで温風の供給を制限するよ
う動作する。同様に、冷房モードにおいて、ＶＡＶダン
パ７はＴ＜８のときはＴ＝８になるまで冷風の供給を制

れるので暖房運転および冷房運転が円滑に行なわれるの
である。On the other hand, the conditioned air in the air conditioner 1 is warm air during heating operation in winter, and cold air during cooling operation in summer. Therefore, in the heating mode, the VAV damper 7 supplies warm air until T=8 when T
>8, it operates to limit the supply of hot air until T=8. Similarly, in the cooling mode, the VAV damper 7 operates to limit the supply of cold air until T=8 when T<8, and to supply cold air until 'I'=S when T>S. do. That is, since warm air is supplied in the heating mode and cold air is supplied in the cooling mode, heating and cooling operations are performed smoothly.

間期に、空調用空気に温風又は冷風を使用することなく
外気を直接、供給する場合がある。このときの空調用空
気の温度をＲとすると下記の温度条件の下で運転が行な
われる。By the way, in the above-mentioned VAV air conditioner, outside air may be directly supplied as air conditioning air without using hot air or cold air during the intermediate period between winter and summer. Assuming that the temperature of the air conditioning air at this time is R, operation is performed under the following temperature conditions.
ところで（１）のＲ＞Ｔ、Ｔ＜８のときに冷房モードで
運転するとダンパ７は閉じるのでＴは上昇しないから（
１）の場合は暖房モードで運転をすべきである。次に（
２）のＲ＜Ｔ、Ｔ＜８の場合に暖房モードで運転すると
ダンパ７が開いて温度の低い空調用空気が温度の低い室
内空気の温度をさらに低下させるので（２）の場合は冷

場合は暖房モードで、また（４）の場合は冷房モードで
運転することを要する。By the way, when R>T and T<8 in (1), when operating in cooling mode, damper 7 closes and T does not rise (
In the case of 1), you should operate in heating mode. next(
If R<T and T<8 in 2), when operating in heating mode, the damper 7 opens and the low-temperature air conditioning air further lowers the temperature of the low-temperature indoor air, so in the case of (2), the operation is in cooling mode. I have to drive. Similarly, in case (8), it is necessary to operate in heating mode, and in case (4), it is necessary to operate in cooling mode.

Since this was done manually, there is the unavoidable possibility that the driver may make the wrong selection and drive under adverse conditions. It is an object of the present invention to provide a control system for a VAV air conditioner that does not have these drawbacks.
