Novel designs and configurations for heat exchangers that improve heat transfer efficiency, compactness, or enable specific phase change or separation processes within refrigeration and heat pump cycles.

Techniques and structures within heat exchangers designed to enhance heat transfer efficiency by controlling and optimizing fluid flow, including baffle arrangements, jet impingement, and condensate management.

Heat transfer devices that utilize the phase change of a working fluid (evaporation and condensation) to efficiently move heat, often incorporating capillary structures, heat pipes, or vapor chambers.

Specific heat exchanger designs and auxiliary components tailored for integration into refrigeration, air conditioning, or heat pump systems, often involving gas-liquid separation or rotary mechanisms.

Membrane-based separation for water purification, contaminant removal, desalination, and wastewater treatment, including reverse osmosis, ultrafiltration, and forward osmosis modules.

Non-chemical or non-biological methods that alter the physical properties or structure of water, often claimed to improve its quality or interaction with biological systems, such as vortexing or electromagnetic treatment.

Design and optimization of fin structures, baffles, and surface textures within heat exchangers to increase heat transfer area, promote turbulence, or manage fluid flow for improved thermal performance.

Systems and methods for intelligent control of HVAC equipment, often incorporating sensors, communication networks, and adaptive algorithms to optimize comfort, energy efficiency, and operational parameters.

Engineering and diagnostic aspects of individual heating, ventilation, and air conditioning components, such as PTC heaters, air ducts, flow control valves, and compressor monitoring.

Design and control strategies for improving the efficiency, stability, and operational flexibility of refrigerant circuits, including component integration, flow management, phase separation, and pressure regulation.

Technologies focused on improving indoor air quality by removing pollutants, microorganisms, or excess humidity, often employing specialized materials, filtration, or air circulation strategies.

Specific techniques and materials developed to remove persistent or difficult-to-treat pollutants from water, such as per- and polyfluoroalkyl substances (PFAS), micropollutants, or specific industrial chemicals.
