［産業上の利用分野］

回転数を小さくして過負荷保護を行う空気調和機
に関するものである。[Detailed explanation of the invention] [Industrial application field] This invention sets the indoor air flow rate by the indoor fan to a weak airflow during heating operation, and the rotation speed of the compressor is kept low until the indoor temperature reaches around the set temperature. When the indoor temperature reaches around the set temperature, the room temperature is controlled as a low capacity operation with a low compressor rotation speed, and in the event of an overload, the compressor rotation speed is prioritized over room temperature control to reduce the overload. This invention relates to an air conditioner that performs load protection.
［従来技術］

ないようにする点とを考慮して、両者の妥協点的
な風量に設定されていた。[Prior art] Generally, in this type of air conditioner, the amount of indoor air blown by the indoor fan is set to three levels: strong air, medium air, and weak air. When the temperature is low or during low capacity operation with low compressor rotation speed, the amount of air blown out is too large and the feeling of cold air is not felt. When the indoor temperature is high and the compressor pressure is high. To,
The air volume was set as a compromise between the two, taking into consideration the need to prevent overload protection from activating if the amount of blown air is too small, which would reduce the rotational speed of the compressor and reduce the heating capacity. .

ることができないという問題点があつた。[Problems that the invention aims to solve] As mentioned above, the conventional "low air" setting requires setting the air volume low so as not to give a feeling of cold air, and setting the air volume high so as not to reduce the heating capacity. Since the decision was made by a compromise between conflicting requirements, the settings were half-hearted, and if the air volume was set to satisfy one requirement, it would not be possible to satisfy the other, and both requirements would not be satisfied. There was a problem that both of them could not be satisfied.
本考案は上述の問題点に鑑みなされたもので、

It is an object of the present invention to provide an air conditioner that does not give a feeling of cold air during heating operation and does not cause a decrease in heating capacity.

い。[Function] During heating operation and when the indoor fan is set to "weak wind", when the indoor temperature is lower than the second set temperature, there is no comparison output from the comparison means, so the indoor fan produces a "weak breeze" and gives a feeling of cold air. The compressor operates at high capacity to control the room temperature. When the indoor temperature reaches the second set temperature, a comparison output appears on the output side of the comparison output, and based on this comparison output, the air volume increasing means increases the rotation speed of the indoor fan to change the indoor air flow from weak to weak air. Strong and weak winds increase to promote heat exchange and suppress compressor pressure rise. Therefore, the overload protection operation does not work, the compressor continues to operate at high capacity, and the heating capacity does not deteriorate. Moreover, the second set temperature is set at a temperature that does not give a feeling of cold air even if the indoor air flow rate is increased from a weak breeze to a strong weak breeze, so an increase in the air volume does not give a feeling of cold air.

い。(b) Next, when the remote controller 16 sets the indoor air flow rate to weak air and sends a power-on signal at time t 0 , the rotation speed R of the compressor 20 is set by the control signal from the microcomputer 13. The pressure P of the compressor 20 increases as shown by the solid line in Fig. 2c , and the pressure P of the compressor 20 increases as shown by the solid line in Fig. 2c, resulting in high capacity operation. Therefore, the room temperature T rapidly rises as shown by the solid line in FIG. 2a. At this time, the indoor temperature T is the second set temperature T 2
Since it is lower, there is no comparison output from the comparison means of the microcomputer 13, and only the fourth relay coil 94 is excited by the drive signal of the driver circuit 10. Therefore, the movable piece 64 of the fourth relay switch 44 connects to the normally open contact 54 , the rotational speed of the indoor fan 2 becomes the minimum value, and the indoor air flow rate F becomes as shown by the solid line in Fig. 2d. When the indoor temperature T reaches the second set temperature T 2 as shown by the solid line in Figure 2 a at t 1 o'clock, the weak wind F 4 becomes (c). , the driver circuit 10 is the fourth relay coil 9 4
is de-energized and the third relay coil 93 is energized, so the movable piece 64 of the fourth relay switch 44 switches to the normally closed contact 84 side, and the movable piece 63 of the third relay switch 43 switches to the normally closed contact 84 side. switches to the normally open contact 53 side. Therefore, the rotational speed of the indoor fan 2 increases, and the indoor air blowing amount F increases from a weak weak wind F4 to a strong weak wind F3 , as shown by the solid line in FIG. 2b. Therefore, heat exchange in the heat exchanger on the user side is promoted, and the pressure P of the compressor 20 reaches the setting point P 1 of the overload protection operating range, as shown by the solid line in FIG. 2c.
The rotation speed R of the compressor 20 continues at R 1 (maximum value) as shown by the solid line in d in the figure, so high capacity operation continues and the indoor temperature T decreases.
t Even after 1 o'clock, the heating capacity rises rapidly and the heating capacity does not decrease. Indoor air flow is weak from weak wind F 4 to strong weak wind F 3
The amount of air blown increases by switching to the second set temperature T 2 (for example, 18°C) at the time of this switching, so you will hardly experience the feeling of cold air. do not have.

暖房能力が低下し室内温度Ｔは第２図ａに点線
で示すように上昇率が低下する。 In addition, in the conventional example, the weak wind was set only to a constant value close to F 4 , so when the indoor temperature T rose, heat exchange in the user heat exchanger was not promoted, and the temperature decreased slightly from t 1 o'clock. At the elapsed time t 2 , the pressure P in the compressor 20 reaches the set value P 1 of the overload protection operating range, as shown by the dotted line in FIG. 2c. Therefore, an overload protection operation that takes priority over room temperature adjustment works, that is, the overload detection sensor 14
The inverter control circuit 18 and the inverter circuit 19 are activated by the control signal from the microcomputer 13 based on the detection signal from the microcomputer 13, and the rotation speed R of the compressor 20 is changed from R1 to R1 as shown by the dotted line in FIG. 2d.
R is reduced to 2 , resulting in low capacity operation. Therefore,
As the heating capacity decreases, the rate of increase in the indoor temperature T decreases as shown by the dotted line in FIG. 2a.

(20℃) (e.g. 19.5℃),
The inverter control circuit 18 and the inverter control circuit 19 are activated by a predetermined control signal from the microcomputer 13, and the rotation speed R of the compressor 20 decreases from R 1 to R 3 as shown by the solid line in FIG. 2d, resulting in low capacity. It becomes driving. Therefore, the pressure P of the compressor 20
As shown by the solid line in Fig. 2c, it rapidly decreases immediately after t 3 , and after that it remains almost constant and never reaches the set value P 1 of the overload protection operating range.
As shown by the solid line in Figure a, the indoor temperature T gradually rises to the first set temperature T1 , and this T1
maintain.

℃), the pressure of the compressor becomes high and the overload protection operation is likely to be activated, but the first set temperature T 1 set by the user
is lower than the second set temperature T 2 (18℃) (for example, 16
℃), the same operation as before is performed, but in this case the pressure of the compressor is not so high and the overload protection operation is almost never activated.

The indoor air flow rate is set to a weak breeze until the indoor temperature T reaches the second set temperature T2 , and after the indoor temperature T reaches the second set temperature T2 , the indoor air flow rate is changed from weak to strong. It was configured to increase in weak winds. Therefore, when the indoor temperature T is lower than the second set temperature T2 , the amount of air blown by the indoor fan is weak and does not give a feeling of cold air. Further, when the indoor temperature T reaches the second set temperature T2 , the rotational speed of the indoor fan is increased by the air volume increasing means based on the comparison output of the comparison means, and the indoor air flow rate is increased to a strong weak wind F3 . Since heat exchange in the exchanger is promoted and the pressure increase in the compressor is suppressed, the overload protection operation does not work or the number of times it works can be suppressed to a smaller number than in the past. Therefore, the duration of high-capacity operation of the compressor becomes longer than before, the heating capacity increases, and the indoor temperature T can be rapidly brought closer to the first set temperature T1 . That is, it is possible to suppress a decrease in the heating capacity due to the overload protection operation. Moreover, the second
The set temperature T 2 is set at a temperature that does not give a feeling of cold air even if the indoor air flow rate is increased from a weak breeze to a strong weak breeze, so an increase in the air volume does not give a feeling of cold air. Moreover, the decrease in power consumption of the compressor due to the decrease in compressor pressure (for example, 50W) is greater than the increase in power consumption (for example, 10W) required to increase the rotation speed of the indoor fan.
It also saves energy.
