When shutting down, timer 31 resets, simultaneously, and the TIR Total Indicator Runout of humidity monitor 9.
During the running beginning, timer 31 set pick up counting.During timer 31 timing to 5 minute, regularly time is up, and at this moment, whole indicator lamp 9a of humidity monitor 9,9b, 9c light.
That is since after the running beginning soon, near the indoor units 1 with the room near the floor, inhabitation territory the temperature difference big, be difficult to carry out rightly humidity display, so the different show state of ordinary circumstance that employing and whole indicator lamps are lighted.Thereby can not transmit inappropriate humidity information to the occupant.
In case the timing of timer 31 arrives, with regard to the temperature T a that detects with temperature sensor 28 humidity (absolute humidity) that humidity sensor 8 detects is revised, and as indoor humidity (relative humidity) H sRead in.
At this moment, room temperature Ta that detects and the room temperature region criterion that is stored in the Fig. 8 in the internal storage are in advance compared, judge that room temperature Ta is in the room temperature T that sets with by remote controller sStill be in the outer B zone of specified scope in the a-quadrant for the specified scope at center.In specified scope, when room temperature Ta rise and fall, can guarantee 0.5 ℃ difference, the jump that can not produce judged result.
If judged result is in the B district, then, can judge indoor humidity H according to the humidity range condition of the table of storing in the internal storage 1 sBe to be in the suitable humidity range, still be in outside the suitable humidity range.
Table 1
Low humidity (%) Suitable humidity (%) High humility (%)
Cold air, dehumidifying running H s≤35 35＜H s＜65 65≤H s
The heating installation running H s≤30 30＜H s＜60 60≤H s
That is, when cold air turns round with dehumidifying, the following H that is limited to of the suitable humidity range in B district S1=35%, on be limited to H S2=65%, the heating installation running is limited to H at present S1=30%, on be limited to H S2=60%.
Indoor humidity H s(H in the time of in suitable humidity range S1＜H s＜H S2) then suitable humidity indicator lamp 9b lights separately.
Indoor humidity H s(H in the time of outside being lower than suitable humidity range s≤ H S1), then only light low humidity indicator lamp 9a.
Indoor humidity H s(H in the time of outside being higher than suitable humidity range S2≤ H sThen only light high humility indicator lamp 9c.
On the other hand, if judged result is in the A district, then can judge indoor humidity H according to the humidity range condition of the table of storing in the internal storage 2 sBe within the suitable humidity range or be in outside the suitable humidity range.
Table 2
Low humidity (%) Suitable humidity (%) High humility (%)
Cold air/wet running H s≤30 30＜H s＜70 70≤H s
The heating installation running H s≤25 25＜H s＜65 65≤H s
That is, when cold air turns round with dehumidifying, the following H that is limited to of the suitable humidity range in A district S1=30%, on be limited to H S2=70%, during the heating installation running, be limited to H down S1=25%, on be limited to H S2=65%.
In a word, compare with the B district of the labile state of Ta wide Ts when running begins, Ta has expanded up and down near the suitable humidity range in the A district of the stable state of target Ts.Can not be subjected to room temperature Ta that appropriate humidity display is made in the influence of suitable humidity range therefrom.
And then, with near the indoor units 1 with the floor, residential area in room near the big heating installation running of the temperature difference time compare, during the cold air operation that has a narrow range of temperature suitable humidity range has been expanded up and down.Thereby during regardless of heating installation and cold air operation, can both carry out humidity display rightly.
Yet because the humidity comfort varies with each individual, for this reason, the inboard of plate 2 is provided with humidity correction switch 12 in front.
When humidity correction switch 12 places " ten " side, make the indoor humidity H that to detect sTo the adjustment in direction that reduces 10%.This adjustment in direction is equivalent to suitable humidity range to high humility one side shifting.
If humidity correction switch 12 is placed "-" side, then with the indoor humidity that detects to the adjustment in direction that increases 10%.Correction to this augment direction is equivalent to suitable humidity range to low humidity one side shifting.
Like this, owing to changing suitable humidity range,, has superior versatility so can dispose according to the shape and the size in the room that indoor units 1 is installed according to occupant's wish.
When indoor temperature Ta arrived the room temperature Ts of remote controller setting, compressor 21 interrupted running.When interrupting running, under the situation that indoor fan 27 shuts down, all indicator lamp 9a, 9b, 9c and the same lighting when shutting down.
That is, near the humidity when stopping owing to indoor fan 27 indoor units 1 is uprised by the influence of the dehumidifying moisture that adheres on the indoor heat converter 25, so indicator lamp is all lighted and can be avoided reporting inappropriate humidity information.
When operation interrupted is removed 27 startups of back indoor fan, timer 31 set, indicator lamp 9a, 9b, 9c all light in 5 minutes.At this moment, owing to, therefore all light and to avoid reporting inappropriate humidity information attached to phenomenons such as the dehumidifying moisture on the indoor heat converter 25 disperse.
During the heating installation running, on the surface of the outdoor heat converter of using as evaporimeter 23, there is frost to adhere at leisure, will causes that owing to heat exchange amount is not enough heat supply efficiency reduces if let matters aside.Therefore, detect, when the temperature that detects drops to 0 ℃, switch cross valve 22, the beginning reverse cycle defrosting with the temperature of 29 pairs of outdoor heat converters 23 of heat-exchanger temperature sensor.
When reverse cycle defrosting, supply with the high temperature refrigerant of discharging to outdoor heat converter 23 from compressor 21, remove attached to the frost on the outdoor heat converter 23 with the heat of high temperature refrigerant.Thereafter, when the temperature of heat-exchanger temperature sensor 29 detections rose to setting, cross valve restored, and reverse cycle defrosting stops, and transferred the heating installation running again to.
Defrosting running continues 5～6 minutes, during this period, interrupt the heating installation running and taked to make indoor fan 27 to stop owing to cooperating, guaranteeing not to measures such as blows cold wind indoors, so, indoor humidity as shown in Figure 9, it is bigger just to have begun to descend, and rises again then.
Utilize this humidity to change big defrosting running, the show state of humidity monitor 9 is constant before the running that can keep defrosting.
In the above-described embodiments, except suitable humidity range, only shown suitable humidity two humidity ranges in addition, still, the demonstration number of its humidity range is not limited thereto, and can suitably set.
As mentioned above, according to the present invention,, can report the air conditioner indoor humidity state, that reliability is high definitely to the occupant so can provide owing to be provided with the device that changes suitable humidity range or make the different device of the form of reporting as required.
