Title: Innovations by Zalman Lavan
Introduction
Zalman Lavan is an accomplished inventor based in Evanston, IL (US). He holds a total of 3 patents that showcase his contributions to the field of refrigeration and air conditioning systems. His innovative approaches have led to significant advancements in energy efficiency and performance.
Latest Patents
One of Lavan's latest patents is an adsorption air conditioning system. This system features an improved adsorbent composition designed for a natural gas-fired, adsorption cooling system. It effectively absorbs moisture from ambient air and can be regenerated at high temperatures ranging from 200 to 300 degrees Celsius. The adsorbent composition may include A-type zeolite, X-type zeolite, or chemically modified Y-type zeolite, either alone or in combination with alumina and/or silica gel. Additionally, a rotating adsorbent wheel made from corrugated paper and a slurry of synthetic organic fibers, preferably polyaramid fibers, enhances the system's performance. The wheel's strength is further improved through surface treatment with alumina or silica solutions and a highly temperature-stable epoxy or phenolic resin.
Another notable patent is the highway vehicle exhaust gas refrigeration system. This energy-efficient absorption refrigeration system is mounted on highway vehicles, such as trucks, and is powered by the hot exhaust gases from the engine. The system utilizes eutectic plates as the evaporator section and features a novel generator-analyzer positioned between the engine and the muffler. An efficient absorbent recirculation loop enhances the system's efficiency, while control problems are minimized by incorporating eutectic plate storage systems with the recirculation loop and compact generator-analyzer. This innovative system is designed to accommodate various refrigerant-absorbent combinations.
