Patent number: 11884126Abstract: An HVAC system includes an evaporator, a heater, a plurality of outlets, and a sliding control door downstream of the evaporator, which is configured to allow air to flow across one or both of a heated path across the heater and a bypass path bypassing the heater. A sliding stratification door is downstream of the temperature control door and positionable to, in an intermediate position, direct air flowing through the bypass path to be mixed with air that flowed across the heated path before flowing out of the plurality of outlets.Type: GrantFiled: July 16, 2021Date of Patent: January 30, 2024Assignee: Air International (US) Inc.Inventor: Joseph J.

Patent number: 11867438Abstract: An HVAC system includes an evaporator, a condenser, a compressor. A first refrigerant path flows through a first expansion valve, first evaporator inlet, within the evaporator, and out of the evaporator through a first evaporator outlet. A second refrigerant path flows through a second expansion valve, a second evaporator inlet, within the evaporator, and out of the evaporator through a second evaporator outlet. Refrigerant flows from the condenser to the first refrigerant path and the second refrigerant path, and from the first refrigerant path and the second refrigerant path to the compressor.Type: GrantFiled: March 18, 2022Date of Patent: January 9, 2024Assignee: Air International (US) Inc.Inventors: Joseph J.

Patent number: 11059345Abstract: A storage evaporator for an air conditioning system in a vehicle is provided that includes phase change material-containing tubes arranged side-by-side in contact with refrigerant-containing tubes. The storage evaporator includes an upper coolant tank, a lower coolant tank, refrigerant-containing tubes fluidly connecting said tanks, and phase change material-containing tubes provided in contact with said refrigerant tubes. The refrigerant tubes have flat sides and the phase change material-containing tubes have flat sides. The flat sides of the refrigerant tubes are attached to the flat sides of said phase change material-containing tubes. The phase change material may be any of several materials and may an eutectic, a salt hydrate, and an organic material. In operation, cold energy is stored in the phase change material when the air conditioning compressor is in its “On” position. This cold energy is released from the phase change material when the compressor is in its “Off” position.Type: GrantFiled: September 13, 2018Date of Patent: July 13, 2021Assignee: Air International (US) Inc.Inventors: Lim Wijaya, Nickolaos Economou

Patent number: 10723196Abstract: An HVAC system according to an example of the present disclosure includes a blower rotatable about an axis. The blower has a first blower section and a second blower section fluidly isolated from the first blower section. An inlet assembly at an axial end of the blower includes a first compartment configured to control fluid flow through the first blower section and a second compartment configured to control fluid flow through the second blower section.Type: GrantFiled: December 16, 2016Date of Patent: July 28, 2020Assignee: AIR INTERNATIONAL (US) INC.Inventors: Wayne Wright, Richard Hoyle

Publication number: 20190204028Abstract: A evaporator provides an evaporator that includes an evaporator core, an evaporator tank attached to the evaporator core, at least one baffle incorporated into the evaporator tank, and multi-piece end plate assemblies attached to the tank. Each end plate assembly includes inner and an outer end plate layers. Each of the layers includes crimps. The inner end plate layer is preliminarily attached to the open end of the evaporator tank, during which proper alignment of the plate to the tank is made. The crimps of the inner end plate layer are crimped over. The outer end plate layer is then preliminarily attached to the inner end plate layer by crimping, thereby allowing preliminary attachment of the end plates to the tank to assure proper alignment prior to the end plates being fixed in position by a method such as brazing.Type: ApplicationFiled: December 29, 2017Publication date: July 4, 2019Applicant: Air International (US) Inc.Inventors: Halim Wijaya, Nickolaos Economou, Marius Daniel Luca, Shen Jie

Publication number: 20190054799Abstract: A two-door HVAC air intake comprising an air intake body having a fresh air opening and first and second recirculated air openings is disclosed. A first door is provided that is movable from a first recirculation opening-unblocking/fresh air opening-blocking position to a first recirculation opening-blocking/fresh air opening-unblocking position. A second door is provided that is movable from a second recirculation opening-unblocking position to a second recirculation opening-blocking position. The doors may be shell doors or flap doors. Fresh air mode is achieved by moving the first and second doors to their recirculation opening-blocking positions. Partial air recirculation mode is achieved by moving the first door to its first recirculation opening-blocking position and the second door to its second recirculation opening-unblocking position.Type: ApplicationFiled: August 18, 2017Publication date: February 21, 2019Applicant: Air International (US) Inc.Inventors: Halim Wijaya, Wu Gui Chao, Yuan Yue, Tang Cheng

Patent number: 7002316Abstract: A drive for a vehicle HVAC vent door includes a drive transmission mounted within the shaft for the vent door. The drive transmission is of the sort commonly known as a wave drive transmission, wherein a lobed member is driven by an oblong drive shaft. The lobed member selectively drives an externally threaded flex ring that in turn engages an internally toothed drive transmission member. The internally toothed drive transmission member drives the shaft for the vent door. In this fashion, a relatively small motor is provided which has sufficient power to drive the vent door. Further, an electrical connection for supplying control signals is mounted at one end of the shaft and has a non-symmetrical configuration such that the motor and vent door will be properly orientated and relative to the vehicle.Type: GrantFiled: August 26, 2004Date of Patent: February 21, 2006Assignee: Air International (US) Inc.Inventor: Richard Hoyle

Patent number: 6715814Abstract: A center console for a vehicle includes air vents at a rear end of the center console. An air passage to deliver heated or cooled air to the vents is formed within the center console by foam molded to the hard plastic which forms the center console housing. The foam is molded to include an internal passage that acts as the air passage.Type: GrantFiled: November 15, 2002Date of Patent: April 6, 2004Assignee: Air International (US), Inc.Inventor: Richard Hoyle
