Aquatic Thermal Refugium System, Device, and Methods (RFT-651)

Invention Summary

This patent introduces an Aquatic Thermal Refugium System designed to regulate localized water temperatures in natural streams. The system features an enclosure partially isolating water, a heat exchanger, and a solar-powered thermal apparatus. It actively cools or heats the water within the enclosure using a fluid that circulates between the heat exchanger and the thermal apparatus, all controlled by a programmable controller. The system is modular, scalable, and tailored to specific aquatic ecosystems.
