An air conditioning system is provided. The air conditioning system allows coolant to selectively flow through a series of bypass pipes and valves connecting an outlet of a compressor and an outlet of an expansion member. The series of bypass pipes and valves allow a defrosting function to be performed without performing a reverse cycle.

Air conditioning system

A silencer having improved noise reduction characteristics is disclosed. The silencer includes a first cylindrical connection pipe for guiding the flow of a fluid, a cylindrical expansion pipe communicating with the first connection pipe at one end thereof for guiding the flow of the fluid, the expansion pipe having a sectional area greater than that of the first connection pipe, and a second cylindrical connection pipe communicating with the other end of the expansion pipe for guiding the flow of the fluid. The expansion pipe has a length (L) decided depending upon a diameter (D) of the first connection pipe or the second connection pipe. According to the present invention, resonance caused by a pipe connected to the silencer is prevented, and therefore, the noise reduction efficiency of the silencer is improved.

Silencer

An air conditioner is disclosed which includes a damper adapted to select a desired path of air humidified by a moisture release portion of a desiccant wheel in accordance with a humidification or dehumidification mode. In accordance with operation of the damper, humidified air is heat-exchanged in a heat exchanger in the dehumidification mode, so that the air is dehumidified. The dehumidified air is discharged into a room. In the humidification mode, the humidified air is directly discharged to the room. Thus, the air conditioner can be used as a humidifier or dehumidifier in accordance with a user selection.

Air conditioner

A humidity adjusting apparatus includes at least one desiccant linearly reciprocated between a dehumidifying unit and a drying unit, and a motor for driving the desiccant to be moved, thereby improving dehumidifying and humidifying efficiency.

Humidity adjusting apparatus using desiccant

An absorption pipe structure of a compressor, capable of reducing vibration of the absorption pipe and making the machinery room small-sized, by making short the length of the absorption pipe connected with the compressor and forming the curved part formed in a proper diameter, is provided.

Absorption pipe structure of compressor

Provided is a pipe structure for an outdoor unit of an air conditioner, in which a length of an induction pipe of a compressor mounted in the outdoor unit is shorter than a connection pipe in the outdoor unit in order to decrease vibration of the outdoor unit of the air conditioner.

Pipe structure for outdoor unit of air conditioner

A pipe structure of an air conditioner, wherein the pipes inside the machinery room are concentrated on one side of the compressor to form long up-down direction so that the pipes inside the machinery room of the air conditioner may be formed in a compact manner, is provided.
