New Energy Sources WhatsAppA Thermal Accumulator Based on Phase-Change Materials
Abstract The concept of a water thermal accumulator based on phase-change materials (PCMs) has been proposed and analyzed. In such a system, energy accumulation (release) occurs due to a phase transition in PCMs, and water is used as a working fluid. The thermal accumulator consists of identical modules, the number of …
