20090288440 | Multichannel Heat Exchanger with Dissimilar Tube Spacing - Heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems and heat exchangers are provided which include dissimilar tube spacing configurations. The heat exchangers include multiple sets of multichannel tubes in fluid communication with each other. One set of multichannel tubes contains a plurality of tubes spaced apart at one spacing while the another set of multichannel tubes contains a plurality of tubes spaced apart at a different spacing. The different spacing between the multichannel tubes allows each set of tubes to be configured to the properties of the refrigerant flowing within the tubes. | 11-26-2009 |
20100050685 | Multichannel Heat Exchanger with Dissimilar Flow - Heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems and heat exchangers are provided that include multichannel tube configurations designed to promote flow of refrigerant within the multichannel tubes near the edges of the tubes that are contacted first by an external fluid. The tube configurations include flow paths of varying cross-sections, spacings, and sizes. Flow control mechanisms, such as inserts, blocking plates, sleeves, crimped sections, and crushed sections, may be employed with the flow paths to favor flow near the edges of the tubes that are contacted first by an external fluid. | 03-04-2010 |
20100162739 | HEAT EXCHANGER - A chiller including a condenser having a refrigerant-storage vessel in fluid communication with a multichannel heat exchanger is disclosed. The chiller further includes a compressor, an evaporator and an expansion device connected in a refrigerant circuit. The refrigerant-storage vessel provides system volume for pump down operations. | 07-01-2010 |
20110088883 | MULTICHANNEL HEAT EXCHANGER WITH IMPROVED FLOW DISTRIBUTION - Heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems and heat exchangers are provided that include multichannel tube configurations designed to reduce refrigerant pressure drop through a heat exchanger manifold. In certain embodiments, tubes inserted within the manifold adjacent to a refrigerant inlet have non-rectangular or recessed end profiles configured to increase flow area near the inlet, thereby reducing a pressure drop through the manifold. In further embodiments, insertion depths of the tubes within the manifold vary based on distance from the inlet. This configuration may establish a larger flow area adjacent to the inlet, thus reducing the pressure drop and increasing heat exchanger efficiency. | 04-21-2011 |
20110126559 | CONTROL SYSTEM - A vapor compression system that circulates a fluid through a closed loop interconnecting a compressor, a first heat exchanger, a flow-restricting expansion device, and a second heat exchanger. The system further includes a vessel in a first fluid communication and a selective second fluid communication with the loop between the compressor and the first heat exchanger with each of the first and second fluid communication configured to receive fluid from the loop. The vessel is in a third fluid communication with the first heat exchanger configured to provide fluid to the first heat exchanger. In response to a predetermined ambient temperature surrounding the system, the second fluid communication is selectively opened to provide an increased fluid flow from the vessel to the first heat exchanger. | 06-02-2011 |
20110192582 | MULTI-SLAB MULTICHANNEL HEAT EXCHANGER - Heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems and multi-slab heat exchangers are provided that include fluid connections for transmitting fluid between groups of tubes. The fluid connections may include generally tubular members fluidly connected to manifold sections. The fluid connections also may include partitioned manifolds containing tubes of different heights. Multichannel tubes are also provided that include a bent section configured to locate a flow path near a leading edge of a tube within one section and near a trailing edge of the tube within another section. | 08-11-2011 |
20120267086 | MULTICHANNEL HEAT EXCHANGER WITH DISSIMILAR FLOW - Heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems and heat exchangers are provided that include multichannel tube configurations designed to promote flow of refrigerant within the multichannel tubes near the edges of the tubes that are contacted first by an external fluid. The tube configurations include flow paths of varying cross-sections, spacings, and sizes. Flow control mechanisms, such as inserts, blocking plates, sleeves, crimped sections, and crushed sections, may be employed with the flow paths to favor flow near the edges of the tubes that are contacted first by an external fluid. | 10-25-2012 |
