Patent number: 10025323Abstract: An apparatus for detecting an oil level and a method for controlling the same, an apparatus for detecting oil flow and a method for controlling the same, and a method for controlling oil return using the detected oil level and the detected oil flow are disclosed. The level of oil stored in a compressor is measured at two or more positions. The frequency comparison scheme using two electrodes can correctly detect the level of oil stored in the compressor, a refrigerant state, and the level of mixed oils, and can determine an internal state of the compressor and a normal or abnormal state of the oil return system, such that the oil return control can be actively controlled. The flow of oil in the oil return pipe is detected so as to determine whether the oil is normally supplied in real time, such that a malfunction of the compressor is prevented and a valve state can be checked.Type: GrantFiled: August 19, 2015Date of Patent: July 17, 2018Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Yong Hee Jang, Hyo Sang Lee, Hyung Mo Koo, Suk Ho Lee, Byoung Guk Lim, Il Yong Cho, Byung Ik Choi, Jeong Su Han
