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

A piping structure of an air conditioner causes a looped main piping connected to a compressor of an outdoor unit of the air conditioner to be branched into two or more branch pipings within a predetermined interval of the main piping and cause the branch pipings to be jointed at an arbitrary location. According to the piping structure, it is possible to reduce a vibration by an interference phenomenon, which is generated when either a refrigerant pulsation or a periodic vibration of the compressor is divided and then combined.

Piping structure for air conditioner

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.

Pipe structure of air conditioner

An improved piping structure of an air conditioner can minimize a vibration by change in a piping shape in looped pipings. In the piping structure, a first directional piping part configured on a same plane is changed to be slanted at a predetermined angle on one end thereof, to be displaced onto a third plane, and to be connected with a second directional piping part configured on a different plane from that of the first directional piping part. Further, the piping structure comprises a vertical piping part wound in an up and down direction and a horizontal piping part connected to the vertical piping part having one end changed at a predetermined slant angle.

Piping structure of air conditioner

Cross flow fan having a plurality of unit fans assembled in succession with the unit fans twisted from each other at sides, and an air conditioner fitted with the same. The unit fan includes an annular rim, and a plurality of impellers arranged on a side of the rim vertical to, and along a circumference of the rim. The present invention provides a cross flow fan extension lines from the impellers of the unit fan have a phase difference with the extension lines from the impellers of an adjacent unit fan. The air conditioner includes a casing having an inlet and an outlet, an indoor unit inclusive of an indoor heat exchanger provided in rear of the inlet inside of the casing, and a cross flow fan having a plurality of unit fans assembled at sides in succession, with the unit fans twisted from each other, the cross flow fan being provided inside of the casing, and the unit fan having an annular rim, and a plurality of impellers arranged on a side of the rim vertical to, and along a circumference of the rim, and an outdoor unit having an outdoor heat exchanger and a compressor, the outdoor unit connected to the indoor unit with refrigerant pipe.

Cross flow fan and air conditioner fitted with the same

Cross flow fan, and air conditioner fitted with the same, the cross flow fan including a plurality of annular rims arranged at regular intervals along a horizontal direction, and a plurality of blades on a side surface of the rim vertical thereto, and along a circumference direction of the rim, wherein pitch angles between two adjacent blades are not regular, the pitch angle taking a center of the rim as an apex, and a number of blades are 32 or 35. The pitch angles of the blades are designed by a computer optimization method taking a number of the blades and the like as parameters.
