Patent number: 11346042Abstract: A drying apparatus is disclosed. The drying apparatus comprises: a drum; a compressor for compressing a refrigerant; a first temperature sensor provided at an air discharge port of the drum; a second temperature sensor provided at a refrigerant discharge port of the compressor; and a processor which, when a drying cycle for an object to be dried begins, compares a first temperature sensed by the first temperature sensor with a predetermined threshold temperature so as to obtain an operation frequency of the compressor, and when a second temperature sensed by the second temperature sensor reaches a predetermined first target temperature, adjusts the operation frequency of the compressor on the basis of a third temperature calculated on the basis of the first temperature and the second temperature.Type: GrantFiled: October 26, 2018Date of Patent: May 31, 2022Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Dong Gyu Lee, Young Uk Yun, Jin Woo Hong, Kwon Jin Kim, Byung Han Lim, Dong Sik Jin

Patent number: 9696095Abstract: A heat exchanger that effectively distributes a refrigerant by varying the cross-sectional area of a header and an air conditioner having the same. The heat exchanger includes a plurality of refrigerant tubes disposed spaced apart from each other, a header joined to both ends of each of the refrigerant tubes, at least one baffle to divide the refrigerant tubes into a plurality of mutually adjacent groups and block a longitudinal flow of a refrigerant flowing in the header, each of the groups causing the refrigerant to flow in one direction, and a booster installed to vary a cross-sectional area of the header to uniformly distribute the refrigerant to refrigerant tubes in the same group among the refrigerant tubes. The booster to vary the cross-sectional area of the header may allow a refrigerant flowing through a header to be effectively distributed to the refrigerant tubes.Type: GrantFiled: June 3, 2014Date of Patent: July 4, 2017Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Dong Gyu Lee, Sung Rok Kim, Dong Sik Jin, Kyoung Rock Kim, Hee Gak No

Patent number: 7762091Abstract: Disclosed herein is an apparatus for controlling the capacity of an air conditioner and a control method using the same. The capacity control apparatus is configured in such a fashion that a 3-way or 4-way direction-switching member and a low-pressure equalizing solenoid valve are provided at a refrigerant path of the air conditioner having a pair of first and second compressors, so that the compression capacity of the air conditioner is adjusted into three stages of 100%, 60%, and 40% using the first and second compressors, enabling easy variable-capacity operation. This has the effect of considerably reducing energy consumption and of preventing wear of the first and second compressors via a rapid compensation of a pressure unbalance between both the compressors.Type: GrantFiled: November 4, 2005Date of Patent: July 27, 2010Assignee: Winiamando Inc.Inventors: Dong Sik Jin, Young Wan Kim, Seok Kyun Kim, Soon Gon Kim
