Patent number: 9702637Abstract: The heat exchanger includes heat exchange units. Each of the heat exchange units includes a plurality of plate fins and a plurality of flat tubes. The plate fins are arranged spaced apart from one another at intervals so as to allow air to flow therebetween. The flat tubes each have an L shape by bending and inserted through the plate fins so that a refrigerant flows therethrough in a direction in which the plate fins are arranged. The heat exchange units are combined to each other so as to form a rectangular shape. Thus, heat exchange can be efficiently performed by increasing the mounting area.Type: GrantFiled: April 26, 2012Date of Patent: July 11, 2017Assignee: Mitsubishi Electric CorporationInventors: Takashi Okazaki, Akira Ishibashi, Sangmu Lee, Takuya Matsuda

Patent number: 9448008Abstract: An air conditioner is provided. The air conditioner includes at least one outdoor unit, a plurality of indoor units, and at least one remote controller to receive operation commands for the plural indoor units. One of the plural indoor units may be selected as a power-supplying indoor unit to supply electric power to the at least one remote controller, based on voltage values of electric power to be supplied from the plural indoor units to the at least one remote controller. The selected indoor unit supplies electric power to the at least one controller. The air conditioner enables a supply of electric power with a sufficiently high voltage to a remote controller by supplying electric power to the remote controller by one indoor unit exhibiting a highest voltage value of electric power to be supplied to the remote controller, as compared to other indoor units.Type: GrantFiled: January 24, 2014Date of Patent: September 20, 2016Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Ji Eun Lee, Su Ho Jo, Kwan Joo Myoung, Awata Hiroshi, Yuodo
