Abstract
Provided is an air conditioner which has a separator with an oil tank for storing extra oil; a first oil return tube opening above the surface of the extra oil; and a second oil return tube opening below the surface of the extra oil. When the refrigeration cycle cannot maintain the required oil dilution ratio as a result of the refrigerant having been replenished to cope with long piping, extra oil can be supplied from the second oil return tube to maintain the required oil dilution ratio in the refrigeration cycle, while using a highly versatile general compressor.
