Publication number: 20080093062Abstract: A heat exchanger includes a plurality of multi-channel heat exchange tubes extending between spaced inlet and outlet headers. Each heat exchange tube has a plurality of flow channels defining discrete flow paths extending longitudinally in parallel relationship from its inlet end to its outlet end. The inlet header has a channel for receiving a two-phase fluid from a fluid circuit and a chamber for collecting the fluid. The chamber has an inlet in flow communication with the channel and an outlet in flow communication with the plurality of fluid flow paths of the heat exchange tubes. The channel defines a relatively high turbulence flow passage that induces uniform mixing of the liquid phase refrigerant and the vapor phase fluid and reduces potential stratification of the vapor phase and the liquid phase within the fluid passing through the header.Type: ApplicationFiled: December 28, 2005Publication date: April 24, 2008Applicant: CARRIER CORPORATIONInventors: Mikhail Gorbounov, Igor Vaisman, Parmesh Verma, Gary Winch, Joseph Sangiovanni

Publication number: 20080092573Abstract: The invention relates to refrigerating systems, primarily, to refrigerating systems employing compressors with economizing inlets and multi-pass condensers. In accordance with the invention a refrigerating system with economizing cycle employs a compressor unit with an economizer inlet and a condenser unit having a first condensation stage, a second condensation stage, and means to remove liquid refrigerant portion between the condensation stages. An intermediate liquid outlet from the first condensation stage feeds a circuit with the evaporator and a liquid outlet from the second condensation stage feeds a circuit with the economizer inlet. The invention provides a high efficiency refrigerating system incorporating of advantages of cost-effectiveness provision of liquid sub-cooling or/and liquid temperature inherent for refrigerating systems with economizing cycle and cost-effectiveness advantages of two-stage condensation condensers.Type: ApplicationFiled: September 27, 2005Publication date: April 24, 2008Applicant: CARRIER CORPORATIONInventors: Igor Vaisman, Mikhail Gorbounov, Jean-Francois Heitz, Kais Djemili

Publication number: 20080092587Abstract: A heat exchanger includes a plurality of flat, multi-channel heat exchange tubes extending between spaced headers. Each heat exchange tube has a plurality of flow channels extending longitudinally in parallel relationship from its inlet end to its outlet end. A plurality of connectors are positioned between the inlet header and the heat transfer tubes such that the connector inlet ends are in fluid flow communication with the header through a relatively small cross-sectional flow area openings and the connector outlet ends are adapted to receive the inlet end of a heat exchanger tube. The connector defines a fluid flow pathway from the relatively small cross-sectional flow area opening in the inlet end of the connector to an outlet opening in the outlet end of the connector that opens to the flow channels of the heat exchange tube received in the outlet end of the connector.Type: ApplicationFiled: December 28, 2005Publication date: April 24, 2008Applicant: Carrier CorporationInventors: Mikhail Gorbounov, Steven Lozyniak, Parmesh Verma, Michael Taras, Robert Chopko, Allen Kirkwood

Publication number: 20080041092Abstract: A heat exchanger includes a plurality of flattened, multi-channel heat exchange tubes of generally J-shape extending between an inlet header and an outlet header. Each heat exchange tube has a base bend that extends horizontally between the vertically extending relatively shorter leg, which is in fluid flow communication with the fluid chamber of the inlet header, and the vertically extending relatively longer leg, which is in fluid flow communication with the fluid chamber of the outlet header.Type: ApplicationFiled: December 28, 2005Publication date: February 21, 2008Inventors: Mikhail Gorbounov, Igor Vaisman, Parmesh Verma, Lisa Sylvia, Xiaoyuan Chang, Gary Winch

Publication number: 20070264133Abstract: A heat exchange system for use in operating equipment in which a working fluid is utilized needing a heat exchange system to provide air and working fluid heat exchanges to cool the working fluid at selectively variable rates in airstreams. The system comprises a plurality of heat exchangers including a first heat exchanger in the plurality of heat exchangers that is mounted with respect to the equipment so as to permit corresponding portions of the airstreams to pass through the core thereof during at least some such uses of the equipment. Also, a second heat exchanger is mounted with respect to the equipment so as to selectively permit corresponding portions of the airstreams to pass through the core thereof during such uses of the equipment. A core actuator is mounted with respect to the second heat exchanger to selectively increase or reduce the passing of those corresponding portions of the airstreams through the core.Type: ApplicationFiled: May 11, 2006Publication date: November 15, 2007Applicant: United Technologies CorporationInventors: Frederick Schwarz, Mikhail Gorbounov

Publication number: 20060102332Abstract: A comb-like insert having a body and plurality of tapered fingers is installed with its fingers disposed within respective minichannels. The fingers and their respective minichannels are so sized as to restrict the channels and frictionally hold the insert in place in one dimension while providing for gaps in another dimension such that the flow of refrigerant is somewhat obstructed but allowed to pass through the gaps between the insert fingers and the minichannel walls and then expand as it passes along the tapered fingers to thereby provide a more homogenous mixture to the individual minichannels. A provision is also made to hold the insert in its installed position by way of internal structure within the inlet manifold. In one embodiment, an internal plate is provided for that purpose, and the plate has openings formed therein for the equalization of pressure on either side thereof.Type: ApplicationFiled: November 12, 2004Publication date: May 18, 2006Applicant: Carrier CorporationInventors: Michael Taras, Allen Kirkwood, Robert Chopko, Mikhail Gorbounov, Igor Vaisman, Parmesh Verma

Publication number: 20060016214Abstract: In a refrigeration system having a pressurizer, a condenser, an expansion device and an evaporator, with the evaporator having an inlet header, an outlet header, and a plurality of channels therebetween, the outlet header has a liquid outlet and a vapor outlet and provision is made for separation of refrigerant liquid from refrigerant vapor. The liquid refrigerant is passed through a superheating heat exchanger to obtain complete evaporation and superheating prior to passing to the pressurizer. Various other features are provided to enhance the system operation.Type: ApplicationFiled: July 13, 2005Publication date: January 26, 2006Applicant: Carrier CorporationInventors: Mikhail Gorbounov, Joseph Sangiovanni, Igor Vaisman
