The bottom of the storage compartment includes a main floor and a sub floor lower than the main floor. The main floor is formed to be slanted downwardly toward the sub floor, such that condensed water falling on the main floor of the storage compartment flows toward the sub floor and is collected on the sub floor.
US11255582B2	HVAC systems and methods with multiple-path expansion device subsystems A method for cooling air in an HVAC system includes moving refrigerant through a closed refrigeration circuit having, inter alia, an expansion device subsystem, which includes a full-load pathway and at least one partial-load pathway and a flow selector for directing refrigerant flow from the condenser to either the partial-load pathway or the full-load pathway. The method also involves directing refrigerant flow from the condenser to the full-load pathway when the refrigerant pressure is greater than or equal to a first preselected activation pressure and stepping down a refrigerant pressure with a set orifice and directing refrigerant flow from the condenser to the partial-load pathway when the refrigerant pressure is less than a second preselected activation pressure and stepping down a refrigerant pressure with a variable expansion device configured for partial loads. Refrigerant is delivered from the full-load pathway or partial-load pathway to the evaporator.
US11255580B2	Carbon dioxide cooling system with subcooling A system includes a first heat exchanger, a flash tank, a first compressor, a condenser, a second heat exchanger, and a second compressor. The first heat exchanger removes heat from carbon dioxide refrigerant. The flash tank stores the carbon dioxide refrigerant from the first heat exchanger. The first compressor compresses the carbon dioxide refrigerant and sends the compressed carbon dioxide refrigerant to the first heat exchanger. The condenser removes heat from a second refrigerant. The second heat exchanger receives the second refrigerant from the condenser. The second heat exchanger further removes heat from the carbon dioxide refrigerant stored in the flash tank. The second compressor compresses the second refrigerant from the heat exchanger. The second compressor sends the second refrigerant to the condenser.
US11255578B2	Turbo-compressor-condenser-expander An isothermal turbo-compressor-condenser-expander (ITCCE) includes heat-transferring fan blades that are mounted on, or surround, individual conduits to promote air exchange and heat transfer. In operation, the open framework rotates in free air to promote heat exchange. An ITCCE bladed assembly includes a driven central hub assembly with a first fluid coupling. A first inner plenum is in fluid communication with the fluid coupling. A plurality of compressor multiport conduits extend radially, and pass fluid from, the first inner plenum to an outer plenum that acts as an equalizing line. A return path is provided to the fluid coupling from the outer plenum. The conduits can be formed as metal extrusions, including internal ribs that separate a plurality of ports formed therebetween along an entire length of the conduits. The conduits can define an airfoil shape and/or are axially twisted, generating axial airflow. The return path can include return multiport conduits.
US11255576B2	Closed loop energy production from producing geothermal wells Methods and systems for producing thermal or electrical power from geothermal wells. Power is produced from a working fluid circulating in a closed loop within a geothermal well. Geothermal steam or brine at depth transfers heat at higher temperature than at the surface to the working fluid. The working fluid is then used to produce power directly or indirectly. The geothermal production fluid may be stimulated through use of gas lifting or submersible pumps to assist in bringing such fluids to the surface or through the use blockers to encourage the downhole steam advection and brine recirculation through the resource in a connective loop. The working fluid may be compatible with existing direct heat or power generation equipment; i.e., water for flash plants or hydrocarbons/refrigerants for binary plants.
