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: 8721407Abstract: A vehicle includes an air intake that facilitates air transfer from an ambient environment outside the vehicle to a vehicle space. The air intake inhibits liquid transfer from the ambient environment to the vehicle space. The air intake includes an inlet for receiving air from the ambient environment, and an outlet in communication with the inlet. The outlet is disposed in an upper portion of the housing. A blocking member is disposed within the housing adjacent the inlet for preventing upward fluid flow from the inlet directly to the outlet. The air intake receives ambient air through an aperture in a window in the vehicle, thereby reducing the size of the air intake.Type: GrantFiled: November 3, 2005Date of Patent: May 13, 2014Assignee: Ford Global Technologies, LLCInventors: Mike Mandernach, Ranganathan Madhavan, Rachid El Aile, Maria Heirtzler, Arthur Henke, Lim Wijaya

The outlet is disposed in an upper portion of the housing. A blocking member is disposed within the housing adjacent the inlet for preventing upward fluid flow from the inlet directly to the outlet, thereby inhibiting liquid flow through the outlet and into the vehicle space. A portion of the air intake housing is configured for attachment to a vehicle window, and the inlet is configured to be disposed along one edge of the window.Type: GrantFiled: September 12, 2003Date of Patent: May 16, 2006Assignee: Ford Global Technologies, LLCInventors: Lim Wijaya, María Heirtzler, Ranganatha Madhavan, Arthur Henke, Rachid El Aile, Michael Mandernach, Carolyn Tatge, Douglas Zhu
