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.

Disclosed is an indoor unit in an air conditioner of which components are arranged symmetrically so as to enable a compact design. The present invention includes a case having an intake port and a blow outlet, a blower installed inside a central part of the case along a length direction of the case, a heat exchanger installed between the intake port and blower so as to heat-exchange a room air which is sucked in, a fan motor coupled with one side of the blower so as to drive the blower, and a pipe part installed at a space opposite to the fan motor centering around the blower and connected between the heat exchanger an outdoor unit so that an operational fluid circulates through the pipe part.

Indoor unit in air conditioner

Disclosed is an air conditioner using a thermoelectric module enabling to supply users individually with fresh and pleasant air for cooling/heating. The present invention includes a thermoelectric module having high and low temperature parts discharging and absorbing heat by an electric power, a heat-absorption accelerating means connected thermally to the low temperature part of the thermoelectric module so as to accelerate heat exchange between the low temperature part and an air, and a heat-dissipation accelerating means connected to the high temperature part of the thermoelectric module to accelerate heat exchange between the high temperature part and air so as to cool the high temperature part.
