Abstract: A water cooling type air conditioner is provided. The water cooling type air conditioner includes first and second heat exchangers, a refrigerant pipe, and a direction controlling unit. The first heat exchanger performs heat exchange between air and refrigerant. The second heat exchanger performs heat exchange between the refrigerant and cooling water. The refrigerant pipe is connected between the first heat exchanger and the second heat exchanger to guide a flow of the refrigerant. The direction controlling unit is disposed on one side of the second heat exchanger and controls the refrigerant and the cooling water flowing inside the second heat exchanger to flow in respectively opposite directions.

Abstract: An air conditioner is disclosed. The air conditioner includes a frame having air suction holes formed at upper and opposite lateral surfaces thereof and an air discharge hole formed at a front surface thereof, a heat exchanger having upper, left and right heat exchanger portions located along the air suction holes, and a fan disposed below the heat exchanger and adapted to suction air from radial and rearward directions thereof and to blow the air in a forward direction.

Abstract: A water-cooled air conditioner includes a first heat exchanger where indoor air is heat-exchanged with refrigerant, a compressor for compressing the refrigerant, an accumulator that is installed adjacent to the compressor to filter off liquid-phase refrigerant so that only gas-phase refrigerant can be introduced into the compressor, a plate-shaped second heat exchanger where the refrigerant compressed by the compressor is heat-exchanged with the water, and a refrigerant bypassing unit that selectively operates to allow a portion of the refrigerant compressed in the compressor to be directly returned to the second heat exchanger.
