この発明は冷房ぎみ除湿運転および暖房ぎみ除
湿運転を可能とする空気調和機に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an air conditioner that enables cooling-only dehumidifying operation and heating-only dehumidifying operation.
一般に、除湿運転を可能とする空気調和機にあ
つては、室内熱交換器を２つ備え、一方の室内熱
交換器を凝縮器いわゆる再熱器として作用させる
ことにより、除湿空気を通常温度まで再加熱して
から室内へ吹出すようにしている。
In general, air conditioners capable of dehumidifying operation are equipped with two indoor heat exchangers, and one of the indoor heat exchangers functions as a condenser or reheater to bring the dehumidified air up to normal temperature. It is then reheated before being blown into the room.
ところで、このような空気調和機においては、
室内への吹出し空気温度が外気温度の変化に伴な
つて変化するという問題がある。すなわち、外気
温度が上昇するとそれに伴なつて吹出し空気温度
も上昇し、室内が暑くなつてしまう。また、外気
温度が低下すればそれに伴なつて吹出し空気温度
も低下し、室内が冷え過ぎてしまう。 By the way, in such an air conditioner,
There is a problem in that the temperature of the air blown into the room changes as the outside air temperature changes. That is, when the outside air temperature rises, the temperature of the blown air also rises, making the inside of the room hotter. Further, if the outside air temperature decreases, the temperature of the blown air also decreases, causing the room to become too cold.
そこで、除湿運転時、室外フアンの運転をオン
またはオフして再熱器の熱容量を変化させること
により、外気温度が高い場合には冷房ぎみ除湿運
転を行なつて吹出し空気温度を低下させ、外気温
度が低い場合には暖房ぎみ除湿運転を行なつて吹
出し空気温度を上昇させ、室内を快適な状態に維
持するようにしたものがある。 Therefore, during dehumidification operation, by turning on or off the outdoor fan and changing the heat capacity of the reheater, when the outside air temperature is high, cooling-only dehumidification operation is performed to lower the temperature of the blown air, and When the temperature is low, some devices perform a heating-only dehumidifying operation to raise the temperature of the blown air and maintain a comfortable indoor condition.
しかしながら、第１図に示すように、冷房ぎみ
除湿運転時、外気温度が所定値以上になると冷房
ぎみの度合が不足し、吹出し空気温度を必要吹出
し空気温度（快適な室内循環を得るために最低限
必要な温度）以下に維持することができなくな
り、室内温度が上昇して結局は不快感を生じてし
まう。また、暖房ぎみ除湿運転時、外気温度が所
定値以下になると暖房ぎみの度合が不足し、吹出
空気温度を必要吹出し空気温度以上に維持するこ
とができなくなり、室内温度が低下して結局は不
快感を生じてしまう。 However, as shown in Figure 1, during cooling-only dehumidification operation, if the outside air temperature exceeds a predetermined value, the degree of cooling is insufficient, and the outlet air temperature is adjusted to the required outlet air temperature (minimum for comfortable indoor circulation). It becomes impossible to maintain the indoor temperature below the required temperature, and the indoor temperature rises, eventually causing discomfort. In addition, during heating-only dehumidification operation, if the outside air temperature falls below a predetermined value, the degree of heating will be insufficient, making it impossible to maintain the blowout air temperature above the required blowout air temperature, and the indoor temperature will drop, resulting in failure. It causes a feeling of pleasure.
この発明は上記のような事情に鑑みてなされた
もので、その目的とするところは、室内温度の変
化に追従して対抗する最適な吹出空気温度を確保

This invention was made in view of the above-mentioned circumstances, and its purpose is to reduce relative humidity while ensuring an optimal blowout air temperature that follows and counters changes in indoor temperature. The purpose of the present invention is to provide an air conditioner that can improve comfort.

This invention operates the outdoor fan in a range where the indoor temperature is higher than the set temperature and the deviation between the indoor temperature and the set temperature is large, and reduces the capacity of the compressor as the deviation between the indoor temperature and the set temperature increases. When the indoor temperature is lower than the set temperature and the deviation between the indoor temperature and the set temperature is large, the outdoor fan is stopped, and as the deviation between the indoor temperature and the set temperature increases, the compressor capacity is increased. do.

イジタル制御部２４へ供給される。 FIG. 3 shows the main part of the control circuit. In Fig. 3, 20 is a suction air temperature detection circuit, which is the temperature of the air sucked into the indoor unit, that is, the indoor temperature T a
is detected by the temperature sensor 21. Thus, the detection value T a of the detection circuit 20 is supplied to the microcomputer 22 . Further, the indoor temperature setting T p set by an operation unit (not shown) is supplied to the microcomputer 22 . During dehumidification operation, this microcomputer 22 supplies an operation control command Q according to the indoor temperature T a to the switching circuit 23 . The switching circuit 23 controls the fan motor 9M of the outdoor fan 9 with the operation control command Q.
It is activated or deactivated depending on the situation. In other words, depending on the state of the indoor temperature T a , the cooling-only dehumidifying operation or the heating-only dehumidifying operation is performed as appropriate. In addition, microcomputer 2
2 is the outside air temperature corresponding to the intersection point X of the blown air temperature during heating-only dehumidification operation and the required blown-out air temperature, and the blown-air temperature and required blown-out air during cooling-only dehumidification operation, as shown in FIG. 4a. Three operating regions A, B, and C are stored in advance, each bordering on the outside temperature corresponding to the intersection point Y with the temperature, and to which region of each operating region the indoor temperature T a corresponds is determined. A capacity setting command P to the compressor 1 is issued by. That is, the microcomputer 22 operates in operating ranges A, B, and C depending on the indoor temperature T a.
As shown in Figure 5a and b, the indoor temperature T a
This is done based on the deviation between the temperature and the indoor set temperature T p , and in operating region B where the deviation is less than +3°C and more than -3°C, a capacity setting command is issued to operate the compressor 1 at the rated capacity. P is emitted and the deviation is +
In operating region C above 3°C, a capacity setting command P is issued to increase the capacity of the compressor 1 as the deviation increases, and in operating region B where the deviation is less than -3°C.
The compressor 1 has a control means that issues a capacity setting command P to increase the capacity of the compressor 1 as the deviation increases. The ability setting command P is then supplied to the digital control section 24.

房ぎみ除湿運転が行なわれる。 When a dehumidifying operation is started using an operation unit (not shown), the compressor 1 starts operating, the solenoid valve 4 is opened, and the solenoid valve 7 is kept closed. Thereby, a dehumidification cycle is formed, and the first indoor heat exchanger 5 acts as a reheater. Then, the operation of the indoor fan 10 is further started, and dehumidified air is blown into the room. At this time, the detection circuit 20 detects the indoor temperature T a , and if the indoor temperature T a is relatively high, the microcomputer 22 issues an operation control command Q to operate the outdoor fan 9 . Thus, when the outdoor fan 9 is operated, cooling and dehumidifying operation is performed. Conversely, if the indoor temperature T a is relatively low, the microcomputer 22 issues an operation control command Q to stop the operation of the outdoor fan 9 .
When the operation of the outdoor fan 9 is stopped, a heating-only dehumidifying operation is performed.

If the indoor temperature T a corresponds to the operating region B, then
A capacity setting command P is issued to operate the compressor 1 at the rated capacity regardless of the cooling-only dehumidification operation or the heating-only dehumidification operation. Then, the digital control unit 23 and the inverter circuit 27 operate the compressor motor 1M at a steady rotation speed, and the compressor 1 is operated at its rated capacity.

ようにしており、これにより室内が暑くなるよう
なことはない。 By the way, the indoor temperature T a rises and the operating region C
(In this case, the cooling-only dehumidifying operation is being performed), the microcomputer 22 has a capacity corresponding to the difference (T a - T p ) between the indoor temperature T a and the indoor set temperature T p . A capacity setting command P is issued to operate the compressor 1. In this way, as the indoor temperature T a is higher than the indoor set temperature T p , the rotation speed of the compressor motor 1M increases, and the capacity of the compressor 1 increases. In other words, when the degree of cooling is insufficient, the degree of cooling is increased by the amount of the shortage, so that the room does not become hot.

であり、外気温度の上昇に伴なう室内温度の上昇

つ、相対湿度の低下が図れ、快適性が向上する。 In other words, it increases the cooling capacity and lowers the temperature of the blown air, while at the same time increasing the dehumidification capacity, ensuring an optimal blown air temperature that follows and counters the rise in indoor temperature due to the rise in outside air temperature. At the same time, relative humidity can be lowered and comfort improved.

うにしており、これにより室内が低え過ぎてしま
うことはない。 Furthermore, when the indoor temperature T a decreases to a state corresponding to operation region A (in this case, the heating-only dehumidifying operation is being performed), the microcomputer 2
2 is the difference between the indoor temperature T a and the indoor set temperature T p (T a −
A capacity setting command P is issued to operate the compressor 1 at a capacity corresponding to T p ). Thus, the indoor temperature
As T a is lower than the indoor set temperature T p , the rotation speed of the compressor motor 1M increases and the capacity of the compressor 1 increases. In other words, when the degree of heating becomes insufficient, the degree of heating is increased by the amount of the deficiency, thereby preventing the indoor temperature from becoming too low.

であり、外気温度の低下に伴なう室内温度の下降

つ、相対湿度の低下が図れ、快適性が向上する。 In other words, it increases the reheating capacity to raise the temperature of the blown air, and at the same time increases the dehumidification capacity, which allows the optimum blown air temperature to follow and counter the drop in indoor temperature that occurs with the drop in outside air temperature. It is possible to reduce the relative humidity while ensuring the same level of humidity, improving comfort.

As described above, according to the present invention, in a range where the indoor temperature is higher than the set temperature and the deviation between the indoor temperature and the set temperature is large, the outdoor fan is operated and the deviation between the indoor temperature and the set temperature increases. Therefore, the capacity of the compressor is increased, and the outdoor fan is stopped when the indoor temperature is lower than the set temperature and the deviation between the indoor temperature and the set temperature is large, and as the deviation between the indoor temperature and the set temperature becomes large. The compressor has a configuration that increases the capacity of the compressor, so it is possible to maintain an optimal blow-out air temperature that follows and counters changes in indoor temperature, while reducing relative humidity and producing air that improves comfort. We can provide a harmonizer.
