Publication number: 20100162751Abstract: A flow of refrigerant discharged from a first compressor and cooled by a radiator is branched by a first branch portion, and the branched refrigerant of one side is decompressed and expanded by a thermal expansion valve and is heat exchanged with the branched refrigerant of the other side in an inner heat exchanger. Therefore, the branched refrigerant of the other side supplied to the suction side evaporator and a nozzle portion of an ejector can be cooled, thereby improving COP. Furthermore, a suction port of a second compressor is coupled to an outlet side of the ejector so as to secure a drive flow of the ejector, and the refrigerant discharged from the second compressor and the refrigerant downstream of the thermal expansion valve are mixed to be drawn into the first compressor so that an ejector-type refrigerant cycle device can be operated stably.Type: ApplicationFiled: December 14, 2009Publication date: July 1, 2010Applicant: DENSO CORPORATIONInventors: Haruyuki Nishijima, Etsuhisa Yamada, Youhei Nagano, Masami Taniguchi

Publication number: 20100162752Abstract: One ozone concentrating chamber is provided therein with a part of a cooling temperature range where ozone can be selectively condensed or an oxygen gas can be selectively removed by transmission from an ozonized oxygen gas, and a part of a temperature range where condensed ozone can be vaporized, and condensed ozone is vaporized by moving condensed ozone with flow of a fluid or by gravitation to the part where condensed ozone can be vaporized, whereby the ozonized oxygen gas can be increased in concentration. Such a constitution is provided that a particle material 13 for condensation and vaporization filled in the ozone concentrating chambers 11 and 12 has a spherical shape of a special shape with multifaceted planes on side surfaces, or an oxygen transmission membrane 130 capable of selectively transmitting an oxygen gas in an ozone gas is provided.Type: ApplicationFiled: November 29, 2006Publication date: July 1, 2010Applicant: Toshiba Mitsubishi Electric Industrial SystemsInventors: Yoichiro Tabata, Tetsuya Saitsu, Yujiro Okihara, Nobuyuki Itoh, Rayohei Ueda, Yasuhiro Tanimura, Koji Ohta
