Air conditioner

Abstract

Provided is an air conditioner. The air conditioner includes a mechanical chamber receiving a compressor for compressing a refrigerant and a water-cooled heat exchanger for heat-exchanging water introduced from the outside and flowing along a water pipe with the refrigerant, an air-cooled heat exchanger disposed on a top surface of the mechanical chamber, the air-cooled heat exchanger being fluidly connected to the compressor, and a fan disposed above the air-cooled heat exchanger. A refrigerant pipe constituting the air-cooled heat exchanger is bent several times along an outer edge of the fan and has a polygonal pillar shape extending in a vertical direction.
