Secondly, situation when air-conditioner with said structure is used for the adjacent room in two in the rooms that change 10 8 (room that faces south) shown in Figure 2 and the rooms that change 11 (dining room) 6 is described.In addition, this air-conditioner is installed in room on the sunny side.
At first, if when the partition 12 of two adjacent room is in open mode, normal condition is set in the room that this room that two adjacent rooms are regarded as and 1 14 changes can be equal to, so the selector button on the remote controller 45.Like this, this air-conditioner just according to the normal condition in the table 1, in other words as the 14 type work of using alternately, therefore,, can make adjacent two rooms keep comfortable environment by the operation of other button on the remote controller 4.That is to say, the transport maximum electric current of outdoor location 3 (the transport maximum electric current that is equivalent to compressor) is controlled in 14.5A, simultaneously, when air quantity setting shelves are " high wind ", the rotating speed of indoor fan is 1300 rev/mins, being 1150 rev/mins when " weak wind ", is 1000 rev/mins when " gentle breeze ", therefore above-mentioned two adjacent 14 repeatedly size the room can with to sufficient air-conditioning.
, the partition between the two-phase next door 12 is being closed, only to the rooms that change 10 8 (room that faces south) when carrying out air-conditioning, if continue the normal condition that keeps above-mentioned, air-conditioning power will be excessive, so can produce the problem that illustrated in the example in the past.Therefore, after the selector button 5 on pressing remote controller 4, the setting B state, this air-conditioner is just worked under the B state in table 1.At this moment, the transport maximum electric current (A) of outdoor location 3 (the transport maximum electric current that is equivalent to compressor) is limited in less 5.3A, when the setting class of sending out air quantity is " high wind ", the rotating speed of indoor fan is 1100 rev/mins, it is 1000 rev/mins when " weak wind ", when " gentle breeze " be 900 rev/mins, so the air-conditioning power of this air-conditioner drops to the 8 type sizes of using alternately.
Like this, because each air quantity of conversion is simultaneously set shelves corresponding air quantity and transport maximum electric current (the transport maximum electric current that is equivalent to compressor), the air-conditioning power that adapts of the size in conversion and living space (room) in other words, so as shown in Table 1, noise (the pectinid sound that indoor fan produces) is little, and when heating sendible temperature do not descend, overregulate with the less stress joint also for a short time on the indoor temperature curve in addition, therefore can carry out good adjusting (so that making ambient-temp-stable) to room temperature.
Particularly in apartment type house, in the time of can only installing an air-conditioner device in the room that faces south, a high-power air-conditioner of air-conditioning is installed, when for example the room of the room that faces south and passageway one side adjacent with this room being carried out air-conditioning, can carry out air-conditioning to these two rooms fully with this big or small air-conditioning power.In addition, when closing the partition in adjacent two rooms, if the air quantity of conversion air-conditioner and transport maximum electric current, air-conditioning power is transformed to the power that is suitable for room-size on the sunny side when carrying out air-conditioning, noise is little, can also eliminate degradation problem under the sendible temperature, and can carry out air-conditioning to the room that faces south effectively.
In addition,, in a word, can make noise littler, not hinder sleep by conversion air-conditioning power because therefore the air quantity and the transport maximum electric current of this air-conditioner of energy conversion, for example can reduce its air quantity and transport maximum electric current when sleep.In addition, can prevent coldly or overheated, have and help healthy effect.
In the above-described embodiments, though be with 8 repeatedly and two adjacent rooms that change 6 be the explanation that example is done, but the rooms that change 10 that also are applicable to rooms that change 10 for example and constitute by two adjacent rooms or the room of other combination, setting is adapted to each state of its combination, also can be the same with the foregoing description, the air-conditioning power of this air-conditioner is transformed to the power that is suitable for room-size, can obtain same effect.
