METHOD FOR INSTALLING FREEZER/AIR CONDITIONER

Japanese Patent JP2010019550

A

To shorten the time required for recovering mineral oil remaining in the existing piping used in a freezer/air conditioner employing CFC or HCFC based refrigerant when the existing piping is used in a freezer/air conditioner employing HFC based refrigerant.

Before the freezer/air conditioner employing CFC or HCFC based refrigerant is removed, operation for recovering mineral oil in the refrigerant piping is performed. After the freezer/air conditioner employing HFC based refrigerant is fixed, the time required for mixing ester oil in a compressor uniformly with mineral oil flowing from the existing piping into the compressor is estimated from the operating time, operating mode, operating capacity, and the like of the compressor and the timing for checking oil in the compressor is indicated thus checking refrigerating machine oil in the compressor with good timing.
