転・停止を行う室温調節器の接点である。Generally, the temperature of the evaporator 111 at that point is not necessarily constant depending on the operating conditions, and the dew point of the indoor air is not constant depending on the temperature and humidity of the indoor air, so the moisture attached to the evaporator (1) evaporates. evaporator (1
), which has the disadvantage that it is not always sufficient in terms of effectively utilizing the cooling capacity. Submit an air conditioner that has been shut down. In the figure, the same symbols as in Figures 1 and 2 indicate the same or equivalent parts, α is a dew point thermometer that detects the dew point temperature of indoor air, and the handle is an evaporator that detects the average temperature of the evaporator (1). The thermometer, αη, is a temperature comparison device that compares the dew point temperature and the evaporator temperature, and the α field is the output signal of the temperature comparison device an, which energizes or deenergizes the first electromagnetic relay, and controls the indoor blower (2). The indoor blower control device controls operation/stop, and Ql is the contact point of the room temperature controller that is energized by a comparison signal between the room temperature and the set temperature and controls the operation/stop of the compressor (8) and the outdoor blower (7). It is.

発器（１１は十分に冷却されており。With the above configuration, when the room temperature drops to the lower limit of the set temperature during cooling operation, the room temperature controller detects this, opens the contact α field of the room temperature controller, and connects the compressor (8) and the outdoor fan ( 6) Stop operation. At this point, the evaporator (11) is sufficiently cooled.

適な空気調和機を提供することができる。Next, when the room temperature rises to the upper limit of the set temperature, the room temperature regulator α detects this and closes the contact Q9 of the room temperature regulator. As a result, the compressor (8) as well as the outdoor blower (6)
enters the operating state, and the temperature of the evaporator (1) also begins to decrease. The temperature comparison device αη compares the output signal of the dew point thermometer (to) and the output signal of the evaporator thermometer (IQ), and compares the output signal of the evaporator thermometer (IQ).
When the temperature of 1 becomes lower than the dew point temperature of the indoor air,
The first electromagnetic relay built in the indoor blower control device is energized, and the indoor blower (3) is operated by opening contact 0 of the first electromagnetic relay. In other words, the indoor blower (2)
is independent of whether the compressor (8) is running or stopping, and the evaporator (1)
) becomes lower than the dew point temperature of the indoor air, and the evaporator (
1) Compare the temperature at which the water droplets attached to the evaporator will evaporate and increase the indoor humidity with the dew point temperature of the indoor air that comes into contact with the evaporator, and the water droplets attached to the evaporator will evaporate and increase the indoor humidity. Since the indoor blower is operated only when there is no danger, waste of energy consumed for dehumidification is eliminated, providing an economical and comfortable air conditioner that does not cause discomfort to residents due to increased humidity. can do.
