Abstract:
A system oil separator oil separating section, and heat exchange sections for a filter drier, a compressor and a system oil separator are at least installed in a pipeline that removably connects a high pressure side connector and flon tank to the high pressure side of the flon filling port of an air conditioner, and a pipeline opening/closing device is installed in a predetermined region, thereby constituting a flon recovery system. And when flon is to be recovered from the air conditioner by the flon recovery system, oil is replenished via the low pressure side of the oil filling port by utilization of flon recovery pressure from the flon filling port connected through a check valve adapted to open when acted on by a predetermined pressure to a pipeline that removably connects a low pressure side connector and flon tank to the low pressure side of the flon filling port of an air conditioner.
