Title: **Maryellen Lavin: Innovator in Refrigerant Technology**
Introduction
Maryellen Lavin is a notable inventor based in Hightstown, NJ, whose contributions to the field of refrigerant technology are encapsulated in her three patents. Her innovative work focuses on improving the efficiency and safety of vapor compression refrigeration systems, particularly with the advent of new refrigerants.
Latest Patents
One of Maryellen Lavin's most significant inventions is her patent for a desiccant specifically designed for drying CH2F2 refrigerant, utilizing zeolite. This invention addresses the issue of difluoromethane (R-32), which is gaining traction as a partial replacement for the widely used chlorodifluoromethane (R-22) refrigerant. However, R-32 has demonstrated higher reactivity with the zeolite A adsorbent-desiccant compositions commonly used. Her innovative approach involved using a potassium cation form of zeolite A, where at least 60 percent of sodium cations are replaced with potassium ions. This unique composition, agglomerated with a clay binder and modified to prevent R-32 adsorption, has proven effective in mitigating corrosion and freeze-up problems in refrigeration systems.
