Patent number: 6883603Abstract: A method for controlling operation of a refrigerator having two evaporators is provided which allows food to be effectively stored in refrigerating and freezing chambers of the refrigerator. A Refrigerating-Freezing (RF) cycle and/or a Freezing (F) cycle of the refrigerator and compressor operation are controlled based on temperatures of various chambers within the refrigerator. This may be further enhanced by also controlling operation of the evaporators and their respective evaporator fans to further optimize cooling output and efficiency. In this manner, the various refrigerating and freezing chambers of the refrigerator can be maintained at an appropriate temperature, power consumption is minimized, and load on the compressor can be adequately managed so as to provide for effective food storage.Type: GrantFiled: April 12, 2002Date of Patent: April 26, 2005Assignee: LG Electronics, Inc.Inventors: Jin Koo Park, Yang Kyu Kim, Se Young Kim, Yin Young Hwang, Joon Hyung Park
