Publication number: 20210095883Abstract: A compressed air drying system is provided for removing moisture from compressed air. The drying system is a modular system with multiple drying units arranged parallel to each other. The drying units cool the compressed air and remove moisture from the compressed air. In order to limit the number of drying units used during low demand periods, a separate air valve is included for each drying unit to control the flow of compressed air through the respective drying units.Type: ApplicationFiled: September 30, 2019Publication date: April 1, 2021Inventors: Henry Y.

Publication number: 20210095688Abstract: Aspects of this disclosure provide a centrifugal impeller having a plurality of constant area shrouded channels that inlet or outlet gas when the channel passes stator inlet port or exit port. The stator walls and ports are located closely adjacent the inside diameter (ID) and outside diameter (OD) of the impeller channel openings, allowing gas to enter or exit a channel of the impeller as the shrouded channel passes a stator port and allows gas to be contained within a channel of the impeller as the shrouded channel passes a stator wall. Further, the impeller reuses the pressurized gas flow by reinjecting the pressurized gas flow back into the ID of the impeller via a second inlet port and utilizing moving wave compression energy. The combination and sequence centrifugal processes and moving wave processes create a higher stage pressure ratio, at lower gas flow, with high gas flow turndown as compared to a conventional centrifugal compressor with similar dimensions and operating speed.Type: ApplicationFiled: September 30, 2019Publication date: April 1, 2021Applicant: Ingersoll-Rand CompanyInventor: Charles John Bergh

Patent number: 10179307Abstract: An air compressor system is disclosed that includes a housing sized to enclose an air compressor pump as well as a dryer structured to remove moisture from air that is compressed by the compressor pump. The air compressor pump may be intermittently placed into operation, but the dryer itself is structured in one form to continuously maintain a heat exchanger in a desired temperature range in anticipation of operation of the air compressor pump. The heat exchanger of the dryer can include sufficient thermal mass such that a refrigerant pump of the dryer need not be operated continuously in anticipation of operation of the air compressor pump. While a cooling air flow can be created by operation of the air compressor pump, when the air compressor pump is not operated a cooling fan can be used provide cooling to the heat generating components of the dryer.Type: GrantFiled: April 28, 2017Date of Patent: January 15, 2019Assignee: Ingersoll-Rand CompanyInventors: Paolo De Piero, Stefano Vezil, Charles John Bergh

Each core element is defined by first and second opposing plates permanently fixed together with a fluid flow path formed therebetween. A coolant flow path is formed between adjacent core elements. A fluid seal positioned between adjacent core elements is configured to form a fluid tight seal between the fluid flow path and the coolant flow path. Individual core elements may be removed from the heat exchanger core to permit removal of coolant precipitated material deposits therefrom.Type: ApplicationFiled: June 12, 2017Publication date: December 13, 2018Inventor: Charles John Bergh

Patent number: 9682336Abstract: An impact moisture separator for separating a liquid moisture from a compressed gas. The impact moisture separator includes a plurality of impact plates that are positioned within the inner region of the separator and may be downstream of at least one strut. The strut may be configured to disperse the flow of compressed gas. The impact plates each have a plurality of vanes that extend beyond a plate portion of the impact plates. The vanes are configured to provide a passage for the flow of compressed gases and are offset from the vanes of the adjacent, successive impact plate. Further, the impact plates and strut(s) are tilted toward the incoming flow of compressed gas so as to assist in influencing the downward flow of the compressed gas, and thereby facilitate the flow of separated liquid moisture toward a reservoir of the housing.Type: GrantFiled: May 28, 2014Date of Patent: June 20, 2017Assignee: Ingersoll-Rand CompanyInventors: Michael John Lucas, Charles John Bergh, Willie Dwayne Valentine
