Abstract (en)
A multi-air conditioner capable of simultaneous cooling and heating, includes: a first duct (3) connected to a discharge side of a compressor (1), through which a refrigerant discharged from the compressor (1) passes at the time of cooling operation; a second duct (4) diverged from the first duct (3), through which a refrigerant discharged from the compressor passes at the time of heating operation; and an oil accumulation preventing portion (8) formed at a certain section of the second duct (4) to have a height difference, for preventing oil, which is introduced to the second duct (4) from the compressor (1) together with a refrigerant, from being accumulated in the second duct. Accordingly, the multi-air conditioner capable of simultaneous cooling and heating can prevent damage to the compressor due to a shortage of oil and thusly improve reliability of a compressor by preventing oil accumulation within a duct.
