の欠点があった。Conventional configuration and its problems Conventionally, as a technology for simply providing a dehumidifying function to an air conditioner, a compressor, a condenser, a throttling device 1, and an evaporator were used.
Configure a refrigerant circuit11. L Reduce the rotational speed of the blower that passes indoor air through the evaporator to an extreme lower than that during normal cooling operation, or turn the blower off frequently to reduce the amount of indoor air passing through the evaporator. This method lowers the surface temperature of the evaporator, lowers the sensible heat ratio, and dehumidifies the indoor air without cooling it too much. However, with this technology, the temperature of the air blown from the air blower drops dramatically, making the occupants feel uncomfortable as a cold draft, and at the same time, the rotation speed of the blower drops dramatically. There are drawbacks such as a decrease in the torque of the motor, which may cause the blower IQ to lock, or a decrease in reliability due to frequent turning-off of the motor.

。Next, its operation will be explained. When the operation switch α is closed, the motor (In) is energized via the speed changeover switch (E), and the blower (4) is rotated at the rotation speed set by the speed changeover switch (E), drawing indoor air to the suction port 00. The air is sucked into the room through the evaporator (3), the wind tunnel (5), and the Suita outlet aυ.At this time, the room air reaches the set temperature T of the controller (a).
! If the temperature is higher than that, the temperature regulator (to) is closed, the motor (2) and the motor are energized, the compressor (2) and the blower are operated, and the indoor air is cooled by the evaporator (3). . When the indoor air is cooled to a temperature 1.2 lower than the set temperature T1, it is detected by the controller Q force and the second temperature ii
1'ii q R: Close au. At this time, if the control switch (c) is closed, the coil (2) is energized, the drive unit (a (9)) is activated, and the door (8) closes the opening (6) shown by the dotted line. In this case, the indoor air sucked in from the suction port 01 passes through the evaporator (3) and is dehumidified and cooled, as shown in the wind circuit indicated by the arrow. The evaporator (3) is bypassed and the opening (6
), mixed again in the wind tunnel (5), and blown into the room from the blower outlet by the blower (4). Furthermore, the indoor air temperature decreases and the above set temperature T2
When the temperature reaches the lower set temperature T8, the controller (to) opens the temperature regulator, stops the compressor (2), blower 04, etc., and stops the cooling operation. It is adjusted so that it does not occur. Conversely, if the indoor air temperature rises with the above-mentioned gate (6) open and reaches the set temperature T4, which is lower than the set temperature 'l゛1 and higher than T2, the controller (b) detects °C. , the second temperature regulator Qυ is opened, and the current supply to the coil 1 is stopped. Stiffness result - (8)
closes the opening (6) and switches back to the original cooling operation. The control switch (c) controls the opening and closing of the door (8).
Disable the automatic operation with the controller switch and always leave the door (
This is a switch to close 8) and perform only cooling operation.

The light temperature also decreases, and the heat exchange surface temperature decreases.As a result, the sensible heat ratio of the amount of heat heated by evaporation (3) decreases, and the amount of heat from the air decreases. Excluding ff1d
jl becomes relatively large. In this way, the air that has been dehumidified in this way bypasses the air evaporator (3) and flows in from the Sekiguchi (6), and is mixed in the wind tunnel (5). if increases and is blown out from the outlet. In other words, it becomes possible to dehumidify indoor air without significantly lowering the Suita air temperature. The temperature of the blown air and the dehumidifier are the air volume of the blower (4) and the door (8).
It is possible to control the air passing through the evaporator (a) by controlling the degree of opening of the evaporator (a).

), but it is clear that a single controller may be used for the control. Moreover, it is a matter of course that this controller can be constructed from an electronic circuit. In addition, the door opening/closing controller (room 7) detects the air temperature.
Although control is performed by comparison with a set temperature, control may also be performed by detecting the entire indoor air temperature and comparing it with a set humidity.

た時に低下する様にしてもよい。In addition, in the above embodiment, when the opening bypassing the evaporator was enclosed, the air flow hL of the indoor unit blower was not controlled, but in order to cope with the increase in the air flow rate of the blower due to the decrease in the air passage resistance of the evaporator. Alternatively, in order to control the dehumidifying capacity of the evaporator when the opening is opened, or to more precisely control the Suita air temperature, the rotational speed of the blower may be lowered when the opening is opened.
