Problems solved by technology

Therefore, a disadvantage of the conventional multi-room air conditioner is that each controller cannot be fixedly used in any state without improvement or replacement.
This will cause a problem: in the case where part of the refrigerant accumulates (that is, naturally accumulates) in an outdoor unit that is adjacent to a working outdoor unit, the working unit w

Example Embodiment

[0042] With reference to the drawings, the preferred embodiments of the present invention will be described in detail below.

[0043] To simplify the description of the present invention, the figure symbolically shows two outdoor side units and one indoor side unit. However, the number of outdoor side units and the number of indoor side units are not limited to 2 and 1, respectively, and any number of outdoor side units and indoor side units can be used in the present invention.

[0044] in figure 1 Medium, label 1 1 and 1 2 It stands for the outdoor side unit, and the number 3 represents an indoor side unit (room unit). Outdoor side unit 1 1 Including a collector 10 1 , A compressor 11 1 , An oil (lubricating oil) separator 12 1 , A four-way reversing valve 13 1 , An outdoor heat exchanger 14 1 , An outdoor electric expansion valve 15 1 , And a refrigerant regulating container 16 1 . The number 80 indicates that one is located in the compressor 11 1 Oil surface sensor (detection de

Abstract

In a multiroom air-conditioning apparatus, refrigerant flow between plural outdoor side units is controlled so that abnormality (lack or excess) of refrigerant amount in an outdoor side unit in operation is redressed. For example, when surplus refrigerant exists in an outdoor side unit, the refrigerant flow is so controlled that the surplus refrigerant is pushed out (flow out) into an outdoor side unit in non-operation. In addition, the output of the air-conditioning apparatus is smoothly variable (controllable) in accordance with an air-conditioning load over the whole air-conditioning load range from the minimum (zero) load to the maximum load.
