Title: Innovations by Rebecca Christianson

Introduction

Rebecca Christianson is an accomplished inventor based in Needham, MA (US). She has made significant contributions to the field of thermal energy storage, holding 2 patents that showcase her innovative spirit and technical expertise.

Latest Patents

Her latest invention is a thermal energy battery with enhanced heat exchange capability and modularity. This invention features an insulated tank containing a multitude of densely packed plastic tubes filled with a phase-change material (PCM), such as ice. The PCM changes from solid to liquid and vice-versa, allowing energy to be stored when it transitions from liquid to solid form and released when it transitions back. The tubes are arranged vertically, spanning the height of the well-insulated tank, and are immersed in heat transfer fluid (HTF) contained within the tank. The HTF is an aqueous solution with a freezing point temperature below that of the chosen PCM, remaining in liquid form throughout the battery's operation. Diffusers are strategically located to allow the HTF to be extracted uniformly from the tank, pumped, cooled by a liquid chiller situated outside the tank, and then reinserted back into the tank.
