Charging and discharging of the PCM storage can be achieved through dynamic reset of the supply air temperature. Compared to conventional PCM wall panels, the in-duct PCM storage offers a range of advantages including 1) deeper thermal penetration with forced convection between airflow and PCM, 2) controllable charge\/discharge rate through dynamic supply air temperature control, and 3) negligible indoor comfort impact. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mixed-integer convex programming-based control algorithms were developed for optimal charging\/discharging of the PCM storage, in response to time-of-use electricity rate schedules. These algorithms are easy to implement and can achieve near-optimal control performance. Preliminary economic analysis has shown payback periods of less than 10 months for the packaged storage+control solution. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>References:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hlanze, P., Elhefny, A., Jiang, Z., <strong>Cai, J.<\/strong> and Shabgard, H., In-Duct Phase Change Material-Based Energy Storage to Enhance Building Demand Flexibility, <em>Applied Energy<\/em>, 2022, <a href=\"http:\/\/jcai.oucreate.com\/wp-content\/uploads\/2022\/07\/PCM-Journal-Paper-Rev2-no-marked-changes.pdf\">preprint<\/a>.
