Patent number: 9145900Abstract: Provided is an air blower for an air conditioner. The air blower for the air conditioner includes a centrifugal fan and a fan housing. The fan housing covers the centrifugal fan, and forms a scroll-type flow path having a varying cross-sectional area and guiding air forcibly blown by the centrifugal fan to an outlet. Here, a bottom surface of the scroll-type flow path inclines and is thinnest near a region where the scroll-type flow path ends. The thickness of the bottom surface progressively increases along a straight line running from a region where the bottom surface is thinnest to an opposite outer side of the scroll-type flow path through a center of the centrifugal fan.Type: GrantFiled: December 1, 2011Date of Patent: September 29, 2015Assignee: LG ELECTRONICS INC.Inventors: Jung Hoon Kim, Dong Soo Moon, Jung Woo Lee, Mi Jin Jung

Patent number: 7574872Abstract: A capacity-variable air conditioner is capable of controlling capacity and consumed electricity in response to operation mode. The refrigerant compression quantity of a compressor is variably adjusted by control of open/close operation modes via selective combination of open/close valves of bypass pipes and bypass valve of the compressor in response to the operation mode. The capacity-variable air conditioner discharges some of the refrigerant infused into the compressor while the bypass valve of the compressor is opened under energy saving operation mode, such that refrigerant circulation quantity can be adjustably reduced under the energy saving operation mode where load of the compressor is less than that of a normal operation mode, thereby enabling a reduction in the capacity and consumed electricity.Type: GrantFiled: January 17, 2006Date of Patent: August 18, 2009Assignee: LG Electronics Inc.Inventors: Dong Soo Moon, Hyun Jong Kim, Sim Won Chin
