Publication number: 20120292006Abstract: An air-conditioning apparatus includes a heat medium relay unit accommodating heat exchangers for exchanging heat between a flammable refrigerant and a heat medium different from the refrigerant. The heat medium relay unit is disposed in a space in a structure that is not an air conditioned space. One or more outdoor units are connected to the heat medium relay unit to circulate the refrigerant therein. The outdoor units are disposed in a space outside the structure or a space inside the structure that is not isolated completely from the space outside the structure. One or more indoor units are connected to the heat medium relay unit by a different system than that of the outdoor units. The indoor units circulate the heat medium therein to exchange heat with air related to the indoor space.Type: ApplicationFiled: February 10, 2010Publication date: November 22, 2012Applicant: Mitsubishi Electric CorporationInventors: Koji Yamashita, Hiroyuki Morimoto

Publication number: 20120292914Abstract: An air bleeding arrangement for the cooling system includes a cooling system, which contains a locally highest point where air, being present in the cooling system, collects. A bleeding nipple is connected with the locally highest point for the venting of the air collected. The bleeding nipple is connected with the locally highest point via an air bleeding duct. The arrangement provides that the air bleeding nipple is arranged remote from the locally highest point.Type: ApplicationFiled: May 15, 2012Publication date: November 22, 2012Inventor: Niels Allan Pedersen

Publication number: 20120285659Abstract: Provided are a heat exchanger, a food handler including the heat exchanger, and a manufacturing method of the heat exchanger. The heat exchanger comprises a main body wherein the plurality of flow channels passes through the inside of the heat exchanger in a first direction and a pair of cover members which is fastened to both ends of the main body in the first direction. The plurality of flow channels is composed of a first flow channel which functions as the path for a first flowing fluid which goes in and out through the cover members and a second flow channel which is connected to the side of the main body. Thermal exchange is performed between the first flowing fluid and the second flowing fluid in the direction wherein the first and second flowing fluids cross each other inside of the main body.Type: ApplicationFiled: September 29, 2010Publication date: November 15, 2012Applicant: WOONGJIN COWAY CO., LTD.Inventors: Sang Gu Sim, Chan Jung Park, Sung Jin Kim

Publication number: 20120261090Abstract: A system and method for converting otherwise wasted energy produced in the form of heated gases as a byproduct of an industrial process into electrical energy. At least some waste gases are diverted from a typical exhaust structure through a heat exchanger and back into the exhaust structure. The amount of gases flowing through the heat exchanger is monitored and regulated by a controller. A heat source liquid is simultaneously circulated under pressure through the heat exchanger and through an organic Rankine cycle system. The amount of heat source liquid being circulated is also monitored and regulated by the controller. The ORC system converts the heat from the heat source liquid into electricity.Type: ApplicationFiled: January 26, 2010Publication date: October 18, 2012Inventors: Ahmet Durmaz, Marcelo Andres Lara
