を行なう。BACKGROUND ART In a conventional air conditioner, for example, a circuit that dehumidifies while performing cooling operation is a circuit as shown in FIG. 1A. It consists of an outdoor unit 1 and an indoor unit 2 of a separate air conditioner, and the outdoor unit 1 has a rotary compressor 3, an air-cooled outdoor heat exchanger 4, a capillary tube 5 serving as a pressure reduction mechanism, and an indoor unit. An indoor heat exchanger 6 is provided in the heat exchanger 2, and these sequentially constitute a refrigerant circuit, and an outdoor blower 7 for the outdoor heat exchanger and an indoor blower 8 for indoor heat exchange are provided, respectively. On the indoor unit 2 side, a thermostat (not shown) for adjusting the indoor temperature is provided to appropriately and arbitrarily select the room temperature. In such a circuit, compressor 3
As shown in the time chart in Figure 1B, the operation of the indoor fan 8 and the operation of the compressor 3 are kept constant until the lower limit set point a is reached when the thermostat is set during cooling (dehumidification) operation. The indoor blower 8 is repeatedly operated and stopped at intervals, and the indoor blower 8 is repeatedly operated and stopped in small increments to perform dehumidification while extremely reducing the amount of air blown.

The difference is that the compressor 3a is a rotary dispersion variable type compressor, which is a pole number conversion type or an inverter controlled (frequency conversion type) compressor. Other same symbols indicate the same parts. In this case, the second
As shown in the time chart in Figure B, the compressor 3a
is operated at a low speed with variable rotation speed until the thermostat reaches the lower limit setting point b, and the indoor blower 8 is operated at a very low speed (light breeze). When the room temperature returns after reaching the lower limit set point b, the compressor 3a again enters low speed operation and the indoor blower 8 enters very low speed operation. As described above, in the conventional example shown in FIG. 2, the dehumidifying operation described above is performed by operating the compressor 3a at a low capacity and operating the indoor blower 8 at an extremely low speed.

う課題を有している。Problems to be Solved by the Invention In such a conventional configuration, the capillary tube 5 performs constant pressure reduction, while the indoor heat exchanger 6 operates as an evaporator repeatedly while the evaporation state changes due to indoor load fluctuations. As a result, the indoor temperature (sensible heat) drops considerably due to the instability, and as a result, the sensation of cooling is stronger than the sensation of dehumidification.
Further, since the compressor 3 and the blower 8 are operated and stopped many times, there is a problem that the durability of these devices is deteriorated. Furthermore, in the conventional example shown in Fig. 2,
The dehumidifying operation described above is attempted by operating the compressor 3a at a low capacity and operating the indoor fan 8 at an extremely low speed, but the thermostat senses the room temperature and the dehumidifying operation continues by repeatedly starting and stopping. Therefore, if the indoor temperature is low, the room temperature, which is sensible heat, will decrease, and conversely, if the humidity is high, only a slight decrease in humidity can be expected and the humidity will not decrease. ing.

That is, with respect to the sensor set value line K, the temperature of the sensor 25 changes like a line A, and the temperature of the indoor heat exchanger 23 changes like a line B. However, the pulse signal converter 22 controls the range G to always be within a certain range. That is, this control changes as shown by line C while adjusting the opening degree of the electric expansion valve 21 by the pulse signal converter 22, and at the same time, the indoor blower 26 is turned on as shown by line D and is operated at a very low speed. When it reaches point Y of the sensor set value, it stops, and when it exceeds the center set value and the point where the temperature of the indoor heat exchanger rises, that is, point Y, the indoor blower 26 starts operating again. At the same time, the compressor 18 changes from operation to stop when the temperature of the indoor heat exchanger 23 reaches the lower limit (line B), and then to line B.
When the vehicle starts to rise, the vehicle starts operating from a stopped position. at the same time,
The outdoor blower 20 performs dehumidifying operation while being controlled in stages from strong to medium to weak following line B as shown by line F.

The opening degree of the electric expansion valve 21 and the indoor blower are adjusted so that the difference between the temperature of the indoor heat exchanger 23 acting as an evaporator and the indoor temperature always falls within a certain range of difference, that is, a certain range G. The pulse signal conversion device 22 controls the operation (very low speed) and stop of the compressor 26, the operation and stop of the compressor 18, and the operation and stop of the outdoor blower 20. Note that line H is a differential zone in the detection unit 24 of the indoor heat exchanger 23. Therefore, line A of sensor 25
When the temperature reaches the set temperature, that is, the lower limit temperature, all cooling operations (dehumidification operations) are stopped. In this way, the control device transmits data from the pulse signal converter 22 to the electric expansion valve via the pulse signal converter 22 while keeping the difference between the indoor temperature measured by the sensor 25 and the temperature of the indoor heat exchanger detected by the detection unit 24 constant. Adjust the opening degree of 21 and turn on the indoor fan 26.
It is possible to perform dehumidification operation under the same conditions as cooling operation by operating the air flow rate at ultra-low speed.

This controls the airflow at an extremely low speed.
