Patent number: 6993932Abstract: A refrigerant cycle system in which the arrangement of a connecting pipe for connection between a compressor and an accumulator is improved effectively to recover oil collected in the accumulator to the compressor. The accumulator is installed to be separate from the compressor. A connecting pipe is arranged between the compressor and the accumulator to feed a refrigerant gas separated in the accumulator to the compressor. An oil recovery hole is provided at an inlet portion of the connecting pipe received in the accumulator such that it is arranged at a level higher than a highest level portion of the connecting pipe located outside of the accumulator. A second accumulator may be connected between the connecting pipe and the compressor while being directly installed at the compressor. In this case, the connecting pipe has an outlet portion connected to the second accumulator.Type: GrantFiled: July 14, 2004Date of Patent: February 7, 2006Assignee: Samsung Electronics Co., Ltd.Inventors: Yong Taek Lee, Hyoung Seo Choi, Hyun ll Roh, Moo Gyo Seo

Publication number: 20050085661Abstract: The present invention relates to a process for preparing fluoroacrylic acid ester using a pervaporation composite membrane, in particular, to a process for preparing fluoroacrylic acid ester performed in such a manner that water and unreacted fluoroalcohol generated in esterification between fluoroalcohol and (meth)acrylic acid in the presence of an acid catalyst are condensed and then passed through a pervaporation membrane to effectively remove water, followed by recycling the unreacted fluoroalcohol removed of water. The present process exhibits much higher conversion rate of fluoroacrylic acid ester, allows the decrease of energy consumption and could be performed in environment-friendly manner.Type: ApplicationFiled: July 2, 2004Publication date: April 21, 2005Applicant: KOREA RESEARCH INSTITUTE OF CHEMICAL TECHNOLOGYInventors: Soo-Bok Lee, Dong-Kwon Kim, In Jun Park, Jeong-Hoon Kim, Kwang-Won Lee, Jong-Wook Ha, Kwang-Han Kim, Sang-Man Ahn, Yong-Taek Lee
