Heat Accumulator, Using PCM Materials, in a Smaller Central Heating System

This article details the design, construction, and modeling of a heat accumulator based on two PCM substances, implemented on a test device in 2024.Intended for a small heating system serving a production plant and a housing estate in the Jizera Mountains, the accumulator offers temperature variability and integrates with cogeneration units via an interconnected CHP-accumulator control system.
