Go out temperature threshold Tdt to be compared.Specifically, judgement discharge temperature Tdr (steps whether consistent with discharge temperature threshold value Tdt
ST25), in the case where discharge temperature Tdr is than discharge temperature threshold value Tdt high (step ST25's is no), the aperture of bulge beats
Open α, and return to step ST24.In addition, in the case where discharge temperature Tdr is lower than discharge temperature threshold value Tdt (step ST25's
It is no), the aperture of bulge closes α, and return to step ST24.On the other hand, in discharge temperature Tdr and discharge temperature threshold value Tdt
Under unanimous circumstances (step ST25's be), the aperture of bulge is kept, to the motion stability of air conditioner.
According to comparative example, such as most preferably swollen in the case that when factory dispatches from the factory set to the installation direction of indoor unit as longitudinal direction
The aperture in swollen portion.Moreover, when indoor unit is installed at the scene, if the installation direction of indoor unit is longitudinal, air conditioner high-efficiency operation.
However, the installation direction of machine is other than longitudinal direction, in the case of such as transverse direction indoors, refrigerant is possible to storage and stays.On the other hand,
The aperture of best bulge in the case that factory is set to the installation direction of indoor unit when dispatching from the factory as transverse direction.Moreover, at the scene
When indoor unit is installed, if the installation direction of indoor unit is laterally, air conditioner high-efficiency operation.However, the installation side of machine indoors
In the case of for longitudinal direction, bulge is excessively opened, thus the degree of superheat is insufficient, and it is possible to make the air blown out from indoor unit
Ramp-up time delay and cause heating capacity to reduce.
In contrast, in present embodiment 1, aperture adjustment unit 53 is being judged as special type by judging unit 51
Installation direction be transverse direction in the case of, than being judged as that the installation direction of special type is longitudinal direction by judging unit 51 in the case of
More open the aperture of bulge 14.Therefore, according to the installation direction of indoor unit 3, opening for best bulge 14 can be set as
Degree.That is, in the case that machine 3 is installed in either direction indoors, the amount of refrigerant appropriate can be also supplied.Thereby, it is possible to press down
The storage of refrigerant processed is stayed, and can inhibit the reduction of the running ability of air conditioner 1.In addition, the heat of the indoor unit 3 due to stopping
Loss is reduced, it is thus possible to reduce power consumption.In addition, even if in the case where being connected with the type that the easy storage of refrigerant is stayed
Supplement refrigerant need not be increased.Therefore working hour when installation indoor unit 3 is cut down, so as to cut down for increasing refrigerant
Cost.In addition, since supplement refrigerant need not be increased, thus the concentration of refrigerating machine oil does not reduce.Therefore it is easy to ensure that compression
The reliability of machine 10.
In addition, there is indoor unit 3 the input switch 34a of the information of input installation direction, judging unit 51 to be based on by defeated
The information for entering the installation direction of switch 34a inputs, judges that difficulty is stayed in the storage for the refrigerant for being stored in indoor unit 3.As a result, for example
When installation personnel installs indoor unit 3, if inputting installation direction using input switch 34a, it will be able to be controlled based on installation direction
The aperture of bulge 14 processed.
In addition, indoor unit 3 has the acceleration transducer (not shown) of the information of detection installation direction, judging unit 51
It can judge that the storage for the refrigerant for being stored in indoor unit 3 is stayed based on the information of the installation direction detected by acceleration transducer
Difficulty.In this case, installation personnel does not input installation direction when installing indoor unit 3, but is controlled based on installation direction
The aperture of bulge 14.Therefore convenience is improved.
In addition, it is also equipped with discharge temperature sensor 6, the discharge temperature for detecting the refrigerant being discharged from compressor 10,
Control unit 50 is also equipped with discharge temperature judging unit 52, for judging that the discharge temperature detected by discharge temperature sensor 6 is
It is no consistent with discharge temperature threshold value, it is being determined as that discharge temperature is different from discharge temperature threshold value by discharge temperature judging unit 52
In the case of, aperture adjustment unit 53 adjusts the aperture of bulge 14.Thus, it is possible to control into the discharge temperature that discharge temperature is target
Degree.
In addition, indoor unit 3 is provided with multiple, bulge 14 is provided with multiple, and one is respectively connected in multiple indoor units 3
Bulge 14.In the past, various indoor units were connected in the air conditioner of multiple, for example, be connected with develop at present being capable of multiple sides
To the indoor unit of setting, if thus not individually adjusting the aperture of the bulge being connect with each indoor unit, 3 nothing of each indoor unit
Method plays original ability.However, in the existing control of Fig. 8, there are whole indoor units for example to be set when factory dispatches from the factory
The case where any one installation direction to indoor unit is the aperture of best parameter that is, bulge.In this case, it is installing
When, assuming that a part indoor unit installation direction difference in the case of, cause in a part of indoor unit and remaining room
In interior machine, the storage of refrigerant stays difficulty etc. to change.
In contrast, in present embodiment 1, aperture adjustment unit 53 is being judged as special type by judging unit 51
Installation direction be transverse direction in the case of, than being judged as that the installation direction of special type is longitudinal direction by judging unit 51 in the case of
More open the aperture of bulge 14.Therefore, even if indoors machine 3 be provided with it is multiple in the case of, also can be according to indoor unit 3
Installation direction is set as the aperture of best bulge 14.
