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.
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.
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.
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.
Techniques and mechanisms to optimize the performance, energy consumption, and operational range of compressors in refrigeration and heat pump systems, often involving variable control of compression parameters like volume ratio or speed.
Focuses on optimizing the geometry, structure, and internal flow channels of impellers, blades, and housings to improve fluid dynamics, efficiency, or specific performance characteristics of centrifugal pumps and fans.
Systems and methods for monitoring, regulating, and diagnosing the performance and health of pumps and fans, including speed control, flow rate management, abnormality detection, and safety mechanisms like overspeed safeguards.
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.
Membrane-based separation for water purification, contaminant removal, desalination, and wastewater treatment, including reverse osmosis, ultrafiltration, and forward osmosis modules.
Pumps and blowers specifically adapted or designed for unique fluid types, challenging environments, or particular industrial, medical, or consumer applications, often involving debris, specific gas mixtures, or precise delivery requirements.
Non-traditional refrigeration and heat pump systems that utilize principles other than vapor compression, such as magnetocaloric effects, thermoelectric effects, absorption cycles, or thermochemical reactions.
