〔産業上の利用分野〕

る。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an all-outside air type air conditioner and an air conditioner with an outside air introduction mechanism, and particularly relates to changes in the temperature of the blown air when the indoor thermometer is turned FF during all-outside air cooling. The present invention relates to a control method for reducing the temperature of the air and obtaining an appropriate blowout temperature even in the face of undesigned changes in outside air temperature.

る。As described in P6 and P7 of PF-8601J,
It is constructed so that 100% outdoor air is always drawn in.

Catalog 50EG-I P, PI3, PI published in 1980
As described in 3, the control for all outside air cooling operation is not incorporated, and the system is configured such that outside air cooling only when the outside air is low temperature, that is, all outside air introduction and compressor operation cannot be performed at the same time.
上記従来技術の第１例に於いては、室内サーモＯＦＦ時
には圧縮機が停止するが１００％の外気が導入されるた
め特に室外空気が高温の場合、吹高空気温度が急変する
ため利用者に不快感を与える問題があった。In the first example of the above-mentioned conventional technology, when the indoor thermostat is turned off, the compressor stops, but 100% outside air is introduced, so especially when the outside air is high temperature, the blow height air temperature changes suddenly, so it is difficult for the user to use the compressor. There was an issue that made me feel uncomfortable.
また第２例に於いては、ダンパ装置は室外空気が低温の
場合に適用される外気冷房運転制御のみが考慮されてお
り、圧縮機を運転して、全外気を導入する全外気冷房制
御に関しては配慮されていなかった。In addition, in the second example, the damper device only takes into consideration the outside air cooling operation control that is applied when the outdoor air is low temperature, and the damper device is only concerned with the outside air cooling operation control that operates the compressor and introduces all the outside air. was not taken into account.

気冷房運転制御を可能とし、また室内サーモＯＦＦ時の
吹出空気温度の急変を防止することにあり、また、まれ
に現われる高外気又は低外気温に対しても、適切な吹出
空気温度を得ることにある。The purpose of the present invention is to enable all outside air cooling operation control for an air conditioner with an outside air introduction mechanism, and to prevent sudden changes in the temperature of the blowing air when the indoor thermostat is turned off. Another purpose is to obtain an appropriate blowout air temperature even at low outside temperatures.

制御手段を設けることにより達成される。The above purpose is to provide an air conditioner in which an outdoor unit consisting of a compressor, a condenser, an expansion valve, and an outdoor blower and an indoor unit consisting of an evaporator and an indoor blower are connected via piping to form a refrigeration cycle. A damper device is provided in the ventilation duct, a damper drive device for mixing indoor air with outside air, indoor air detection means, mixed air blowout temperature detection means, and a compressor, depending on the size relationship between the room temperature setting value and the room temperature. This is achieved by providing a control means for controlling the outdoor blower and the damper drive device.

パ駆動装置を駆動させて外気温度よりも低い室内空気を
高温外気と混合せしめ、混合空気温度、即ち吹出空気温
度が室内空気温度よりも一定値以上の範囲に入るべく制
御すれば良い。In other words, the temperature of the blowing air is detected when the indoor thermometer is set to FF,
If the value is higher than the set room temperature by a certain value, the damper drive device is driven to mix the indoor air, which is lower than the outside air temperature, with the high-temperature outside air, so that the mixed air temperature, that is, the blowing air temperature, is more constant than the indoor air temperature. It is only necessary to control the value so that it falls within a range greater than the value.
また冷房時に高外気温度により吹出温度が高くなれば低
温室内空気を導入外気と混合させれば良い。Furthermore, if the blowout temperature becomes high due to high outside air temperature during cooling, low-temperature indoor air may be mixed with introduced outside air.

高い時のみ、ダンパ装置は室内空気を外気と混合させて
吹出空気温度（ＴＤ）の急上昇を押さえるように作動す
る。従ってＴＯがＴＲ３よりも低い場合には、ダンパ装
置は室内換気側に対して閉止の状態のままであり。When the thermostat is ON, the damper device is kept closed to the indoor ventilation side, that is, in a state where all outside air is maintained. When the thermostat is OFF, the blowing air temperature (TD) (equal to the outside air temperature (To)) is the indoor set temperature. Only when the temperature is higher than (TR8) by a certain value, the damper device operates to mix indoor air with outside air and suppress a sudden rise in the blowout air temperature (TD). Therefore, if TO is lower than TR3, the damper device remains closed to the room ventilation side.
不必要に室内空気を再循環することがないので、全外気
運転の特徴を損うことなく、また誤動作することがない
。Since indoor air is not recirculated unnecessarily, the characteristics of all-outside air operation are not impaired and malfunctions do not occur.

Cooling operation (at 70N) Next, when the room temperature TR is higher than the room temperature set value TR3, that is, when the thermostat is ON, when the cooling switch 14c is turned on, the cooling relay 10b is closed. The compressor motor 1a and the outdoor blower motor 3a are operated, the refrigeration cycle is in a cooling operation state, the outdoor air is cooled by the evaporator 6, and low-temperature air is supplied indoors. 3. When the thermostat is OFF, then TR When the value decreases and becomes lower than TR6, that is, when the thermo-FF state is reached, ARC10b is opened,
The compressor motor 1a and the outdoor blower motor 3a are stopped and the cooling operation is stopped, but the control device 10 calculates the value (including positive and negative) after a certain period of time (TR-TR3) and uses it as the draft width setting device 18a. The value ΔTDW set by

る。4. When the blowout air temperature is high during cooling operation If, for example, the outside air temperature becomes high during cooling operation when the thermostat is ON, the blowout air temperature TD is higher than the value TDMAX set by the maximum blowout air temperature setting device 18b. If the temperature increases, the damper device 9 is reversed as in the previous section 3, and the low-temperature indoor air is mixed with the high-temperature outside air, so that the temperature of the mixed air entering the evaporator 6 becomes lower than the outside air temperature, so TD becomes TDMAX.
will be lower than At that point, the damper device 9 is stopped, but after that, when (T, DMAX-TD) becomes a certain temperature or higher, it is preferable to open the damper device 9 again for a certain period of time. This control has the effect of preventing the blowout temperature from becoming excessive even when the outside temperature is high.

きる。Since the present invention is configured as described above, 1. It is possible not only to prevent a sudden change in the blowout temperature when the thermostat is FF, but also indirectly to prevent a sudden increase in indoor humidity when the outside air is humid and high temperature; 2. Even in cooling operation when the outside air temperature is high, it is possible to obtain an appropriate blowout temperature at the expense of some amount of total outside air introduction.In other words, since there was no conventional control technology for this, In this case, the processing air volume was approximately 2/2 of the normal air flow rate relative to the heat exchanger area, but with this method, the normal air flow rate can be applied at the expense of sacrificing the total outside air quality during rare high outside temperatures. .
