Claims

[Scope of utility model registration request]

In a multi-room air conditioner capable of cooling and heating, which consists of connecting multiple indoor units to one outdoor unit, air conditioning is carried out between the compressor suction pipes from the middle of the piping that becomes the high-pressure gas pipe during cooling operation, and between the compressor suction pipes during heating operation. A multi-room air conditioner characterized in that a capillary tube for pressure balance is provided between the compressor suction pipes from the middle of the piping that becomes the high-pressure gas pipe.
