Publication number: 20240118005Abstract: A heat exchanger for use in an outdoor environment with a heat pump system is provided. The heat exchanger includes a first set of tubes arranged in a parallel flow manner between a first manifold and a second manifold, wherein central straight portions of adjacent tubes are disposed with a space therebetween along each tube of the first set of tube between the first and second manifolds. A second set of tubes are arranged in a parallel flow manner between a third manifold and a fourth manifold, wherein central straight portions of adjacent tubes within the second set of tubes are at least partially disposed within the space between adjacent tubes of the first set of tubes. A fluid that flows through the first set of tubes additionally flows through the second set of tubes before the fluid returns to again flow through the first set of tubes.Type: ApplicationFiled: October 11, 2022Publication date: April 11, 2024Inventors: Scott KENT, Robert Louis RUNK, Lindsey Lee LEITZEL, Szymon WALCZAK

Patent number: 8783351Abstract: A cementing tool (20) capable of being installed in a casing string (10) and configured to selectively permit the flow of cement through one or more ports (34) in the tool is provided. The ports (34) are normally sealed by rupture disc assemblies (36) comprising a rupture disc (62) that can be opened to permit flow of cement through the casing string central bore (32) and into the annulus (14) defined by the casing string (10) and the downhole formation (16). The cementing tool (20) is particularly useful during cementing operations in which the annulus (14) has become blocked by a collapsed portion of the formation by allowing the obstruction (104) to be bypassed and the flow of cement (100) into the annulus to be continued without substantial interruption. Tool (20) may also be used in multistage cementing operations.Type: GrantFiled: June 21, 2011Date of Patent: July 22, 2014Assignee: Fike CorporationInventors: Lindsey Lee, Gene Hill, Eddie Malcolm, Jeffrey A. Stokes

Publication number: 20090211293Abstract: An air conditioning system for circulating a refrigerant includes a condenser having a vapor inlet for condensing the refrigerant into a high-pressure liquid having a first predetermined temperature. A heat exchanger including an exhaust channel directs air therethrough. The heat exchanger further includes a refrigerant inlet in fluid communication with a refrigerant outlet for receiving a high-pressure liquid and for delivering the high-pressure liquid therethrough. Furthermore, a heat mass exchanger outputs wet working air having a second predetermined temperature. The heat exchanger is in fluid communication with the heat mass exchanger for receiving the working air having a temperature less than the high-pressure liquid. The working air flows through the exhaust channel and over the high-pressure liquid to transfer heat from the high-pressure liquid to the working air for reducing the temperature of the high-pressure liquid.Type: ApplicationFiled: February 25, 2008Publication date: August 27, 2009Inventors: Edward Wolfe, IV, Ilya Reyzin, Lindsey Lee Leitzel

Cooling fan control method for minimizing the power consumption of a vehicle air conditioning system
Patent number: 6637229Abstract: An improved control method for a vehicle air conditioning system including a refrigerant compressor and a condenser cooling fan adjusts the power consumption of the condenser cooling fan in a manner to minimize the combined power consumption of compressor and the condenser cooling fan while maintaining adequate cooling of the condensed refrigerant. When the air conditioning system is operating at less than full capacity, the combined power consumption of the compressor and the condenser cooling fan is determined for each of a series of operating intervals. The change in the combined power consumption from one operating interval to the next is computed to determine the effect of a prior cooling fan power adjustment, and the power level of the cooling fan is incrementally adjusted in the same direction as the prior adjustment so long as the prior adjustment resulted in at least a specified reduction of the combined power consumption.Type: GrantFiled: October 21, 2002Date of Patent: October 28, 2003Assignee: Delphi Technologies, Inc.Inventors: Wayne Oliver Forrest, Lawrence Scherer, Nicholas Joseph Alonge, Jr., Frank A.

Patent number: 6390217Abstract: An assembly is provided to increase the efficiency of a vehicle engine cooling and supplementary, heat pump type cabin heating system. A flexible panel located in front of and below the front end heat exchanger can be moved between open and blocking positions. An engine cooling radiator and fan are located behind the front end heat exchanger. In cold weather heating mode, the flexible panel can be rolled to the blocking position, preventing the direct flow of cold outside ram air through the front end heat exchanger. At the same time, the fan is reversed, flowing heated air from the radiator through the front end heat exchanger, improving its efficiency.Type: GrantFiled: April 2, 2001Date of Patent: May 21, 2002Assignee: Delphi Technologies, Inc.Inventors: John F. O'Brien, Robert Michael Runk, Lindsey Lee Leitzel

Patent number: 6357242Abstract: An improved system and method for suppressing high side pressure transients in a motor vehicle air conditioning system due to engine speed transients during vehicle acceleration through the use of a throttling valve. The throttling valve may be mechanically or electrically activated, and is connected in the low pressure side of the air conditioning system to controllably restrict refrigerant flow in response to one or more parameters that detect or anticipate a high side transient pressure condition. The parameters may include the high side pressure itself, or engine parameters such as engine speed and vehicle speed. In a preferred embodiment, the throttling valve may be controlled to prevent evaporator icing in addition to suppressing high side pressure transients.Type: GrantFiled: July 20, 2000Date of Patent: March 19, 2002Assignee: Delphi Technologies, Inc.Inventors: Dennis Lee Farley, Mingyu Wang, Lindsey Lee Leitzel
