Abstract
A horizontal-installation-type scroll compressor requiring small installation space adopts a technique which can reduce the amount of refrigerating machine oil circulating through the refrigeration cycle. By using this scroll compressor, an air conditioner is provided whose unit body has a reduced depth and which has satisfactory ventilation efficiency and cyclic efficiency. The scroll compressor includes a closed container which is separated into a section lodging an electric motor and a compression mechanism and a section where a discharge pipe is provided. Refrigerating machine oil is stored in the section including the discharge pipe in order to ensure the requisite amount of refrigerating machine oil. An oil separation mechanism is provided in the passage of the refrigerant gas so that refrigerant gas containing little amount of refrigerating machine oil may be sent out from the discharge pipe. Further, electrical parts and this scroll compressor are arranged below a heat exchange section equipped with a heat exchanger and a centrifugal fan, thus forming an outdoor unit.
