Patent number: 11313567Abstract: A refrigeration cycle apparatus has a compressor disposed via a bottom member of a housing, a second elastic member, a base, and a first elastic member. A first electric component that drives a motor for the compressor and a second electric component that performs another control are fixed to the base and disposed. The base has an upper surface that contacts the first elastic member and a lower surface that contacts the second elastic member. The first electric component and the second electric component are fixed to the upper surface directly or indirectly via a substrate and/or an electric-component casing. Top portions of the first electric component and the second electric component are lower than a top portion of the compressor.Type: GrantFiled: March 22, 2019Date of Patent: April 26, 2022Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Kazushi Hisayama, Tetsuya Okamoto, Yoshinobu Tsumura, Kebi Chen, Masanori Ukibune

Publication number: 20140216094Abstract: An outdoor unit includes: a compressor, and a sound deadening material having sound deadening properties. The sound deadening material includes a first sound absorbing material made of glass fibers, a first scatter prevention member which prevents scattering of the glass fiber from one principal surface of the first sound absorbing material by covering the one principal surface, and a second scatter prevention member which prevents scattering of the glass fiber from the other the other principal surface of the first sound absorbing material by covering the other principal surface. The first scatter prevention member is a sound absorbing material made of fibers having high fiber strength than the glass fibers. The second scatter prevention member is a sound insulating material. The sound deadening material is wound around the compressor so that the first scatter prevention member faces the compressor.Type: ApplicationFiled: July 27, 2012Publication date: August 7, 2014Applicant: DAIKIN INDUSTRIES, LTD.Inventors: Keitarou Hoshika, Takayuki Setoguchi, Yoshinobu Tsumura, Shinichi Negoro
