Abstract

Provided is an air conditioner which comprises multiple outdoor units the air conditioner being configured so that with the use of a low cost configuration required refrigeration machine oil is supplied to all the outdoor units through refrigerant piping and so that the air conditioner has increased reliability. An air conditioner is provided with multiple indoor units and with four outdoor units which are connected to the multiple indoor units through refrigerant piping. A line of first refrigerant piping leading from the multiple indoor units is branched into two lines of second refrigerant piping each of the two lines of second refrigerant piping is branched into two lines of third refrigerant piping and the four lines of third refrigerant piping are respectively connected to the four outdoor units.
