Publication number: 20230383963Abstract: A cooling system utilizes an organic ionic salt composition for dehumidification of an airflow. The organic ionic salt composition absorbs moisture from an inlet airflow to produce an outlet airflow with a reduce moisture from that of the inlet airflow. The organic ionic salt composition may be regenerated, wherein the absorbed moisture is expelled by heating with a heating device. The heating device may be an electrochemical heating device, such as a fuel cell, an electrochemical metal hydride heating device, an electrochemical heat pump or compressor, or a condenser of a refrigerant cycle, which may utilize an electrochemical pump or compressor. The efficiency of the cooling system may be increased by utilization of the waste heat the cooling system. The organic ionic salt composition may circulate back and forth or in a loop between a conditioner, where it absorbs moisture, to a regenerator, where moisture is desorbed by heating.Type: ApplicationFiled: August 7, 2023Publication date: November 30, 2023Inventors: Bamdad Bahar, William Parmelee, Omar Abdelaziz, Qu Ming

Patent number: 10598418Abstract: A method for controlling a heat pump is provided. A working mode of the heat pump is determined. Based on a determination that the working mode of the heat pump is a heating mode, an ambient temperature of the heat pump is determined. Based on a determination that the ambient temperature of the heat pump is higher than a first predetermined temperature, a first compressor of the heat pump is operated. Based on a determination that the ambient temperature of the heat pump is lower than the first predetermined temperature, both the first compressor and a second compressor of the heat pump are enabled to operate, in response to a two-stage thermostat. The first compressor and the second compressor are coupled in parallel. The method allows the heat pump to be suitable for a cold climate.Type: GrantFiled: June 9, 2017Date of Patent: March 24, 2020Assignee: UT-BATTELLE, LLCInventors: Bo Shen, Edward Allan Vineyard, Omar Abdelaziz

Patent number: 10519923Abstract: Systems store energy mechanically at a first time and extract the energy at a later time. When excess electricity from renewable sources or during off-peak periods is available, a pump directs a working liquid (L) to pressurize a gas (G) that is confined within a pressure vessel. When electricity from renewable sources is not available or during periods of peak demand or pricing, the pressurized gas (G) directs the working liquid (L) through a hydropower turbine. The turbine drives a generator through a mechanical coupling to provide electricity for powering a load. In addition, the system can leverage (take) any waste heat as the input to boost the efficiency of the system. The described systems function at ground level and are modular and scalable in capacity.Type: GrantFiled: September 1, 2016Date of Patent: December 31, 2019Assignee: UT-Battelle, LLCInventors: Ayyoub Mehdizadeh Momen, Kyle J.

Patent number: 10443905Abstract: A magnetocaloric cooling system comprising a solid body or bodies, such as a cylinder or cube, having a plurality of channels extending between a first end and a second end of the cylinder or cube and a magnet at least partially surrounding the cylinder or cube. A metallic mass, such as a rod or plate, is positioned within each channel and slides within a respective channel between two sliding extremities so that in each sliding extremity, a portion of each metallic mass extends beyond an end of the solid body. A motor is used for reciprocating the metallic masses between the sliding extremities and a heat exchange mechanism directs heating or cooling where desired.Type: GrantFiled: November 24, 2015Date of Patent: October 15, 2019Assignee: UT-BATTELLE, LLCInventors: Ayyoub Mehdizadeh Momen, Omar Abdelaziz, Edward Allan Vineyard

Patent number: 10386084Abstract: An ionic liquid desiccant system utilizes an ionic liquid desiccant to draw moisture from a working fluid, such as air that flow into an enclosure, such as a home. The desiccant may be mixed with the working fluid or a separator that allows moisture transport therethrough may be configured between the ionic liquid desiccant and the working fluid. The ionic liquid desiccant system may be part of an air conditioning system and may remove the moisture from air that is cooled by flowing over an evaporator or heat exchanger coupled with the evaporator. The ionic liquid desiccant may be pumped from a desiccant chamber to a regenerator chamber to remove absorbed moisture. A dual-purpose chamber may act as a desiccant chamber and as a regenerator chamber. A refrigeration system may have an electrochemical compressor and may utilize metal hydride heat exchangers.Type: GrantFiled: March 30, 2017Date of Patent: August 20, 2019Assignee: Xergy LTDInventors: Bamdad Bahar, William Parmelee, Luyu Jin, Omar Abdelaziz Ahmed Abdelaziz

Patent number: 10151498Abstract: An absorption cycle system, which permits water heating, dehumidifying, and/or evaporative cooling, includes a desorber, absorber, heat exchanger, and, optionally, an evaporator, is constructed to heat a process water that is plumbed through the absorber, heat exchanger, and condenser. In the absence or isolation of the evaporator, the system can dehumidify ambient air to the absorber. The water vapor released by evaporative cooling at the evaporator can be provided to the absorber in a controlled manner to simultaneously maintain a desired humidity while cooling the air ambient by the evaporator. The absorption cycle system can be housed within a single unit or can be compartmentalized.Type: GrantFiled: July 11, 2016Date of Patent: December 11, 2018Assignees: University of Florida Research Foundation, Incorporated, UT-Battelle, LLCInventors: Saeed Moghaddam, Devesh Chugh, Rasool Nasrisfahani, Sajjad Bigham, Seyyed A.
