20110197617 | CHILLER - A chiller is provided that may include a case; a vapor compression type cycle apparatus installed in the case and including first and second heat exchangers that heat-exchange with first and second heat transfer mediums, respectively, the vapor compression type cycle apparatus including a condenser that serves as the first heat exchanger, an evaporator that serves as the second heat exchanger, a compressor, and an expansion device disposed between the condenser and the evaporator, respectively; a blower configured to supply air to the first heat exchanger; and a liquid spray device configured to spray liquid onto the first heat exchanger. | 08-18-2011 |
20140231051 | TURBO FAN AND CEILING TYPE AIR CONDITIONER USING THE SAME - Provided are a turbo fan and an air conditioner using the same. The turbo fan includes a main plate rotating by power provided from a fan motor, a blade having one end connected to the main plate to rotate, a shroud connected to the other end of the blade, and an orifice guiding a flow of indoor air in a direction of the shroud. The shroud includes a guide surface defining one surface of the shroud, the guide surface having a predetermined curvature and an air guide connected to a side of the shroud, the air guide being disposed in a direction of the orifice from the shroud. | 08-21-2014 |
20140234138 | CEILING TYPE AIR CONDITIONER - A ceiling type air conditioner includes a case defining an outer appearance, a fan disposed to a bottom of the case, a turbo fan disposed within the case, the turbo fan including a main plate rotated by power provided from the fan motor and a blade having a side connected to the main plate, and a heat exchanger disposed outside the turbo fan. A cooling passage cooling the fan motor is defined between the main plate and the bottom surface of the case. The cooling passage includes a flow part through which air passing through the blade flows into the flow part toward the fan motor, and a panel installation part to which a panel is installed for adjusting an amount of air flowing into the flow part toward the fan motor. | 08-21-2014 |
20140314575 | TURBO FAN - Provided is a turbo fan. The turbo fan includes a main plate rotating by a fan motor providing power and a plurality of blades having one ends connected to the main plate, the plurality of blades being disposed along a circumferential direction on the main plate. Each of the plurality of blades includes a first curved part curved in one direction with respect to an extension part and a second curved part curved in the other direction with respect to the extension part. A plurality of projections protruding in one direction from the one end of the blade and a plurality of grooves protruding in the other direction are alternately disposed on the first and second curved parts. Alternatively, the turbo fan includes a main plate rotating by a fan motor providing power, a rotation shaft providing a rotation center of the main plate, a plurality of blades having a blade front end disposed adjacent to the rotation shaft and a blade rear end disposed spaced from the rotation shaft, the plurality of blades being disposed in a circumferential direction on the main plate, and an extension part defined as a virtual line straightly extending from an upper portion of the blade rear end to a lower portion of the blade rear end. Each of the blades includes a first curved part curved in one direction with respect to the extension part, a second curved part curved in the other direction with respect to the extension part, a first flow part defined as a space between the extension part and the first curved part, and a second flow part defined as a space between the extension part and the second curved part. | 10-23-2014 |
20140315479 | TURBO FAN AND CEILING TYPE AIR CONDITIONER USING THEREOF - A turbo fan includes a main plate rotated by power provided from a fan motor, blades each having one end connected to the main plate to perform rotation movement, and a shroud having an inner circumferential part and an outer circumferential part, an other end of each of the blades connected to the shroud. The shroud includes a plurality of curved parts each having one side connected to the inner circumferential part and an other side connected to the outer circumferential part, the plurality of curved parts each having a predetermined curvature. | 10-23-2014 |
