Replication Data for: Cold thermal energy storage in solid-liquid transition of carbon dioxide: Investigating the possibility

Industrial freezing is an energy-intensive process which is growing due to the increasing demand. This is exerting stress on electrical grids, especially at peak hours. To tackle this issue, thermal energy storage has received attention; however, there is a gap in terms of suitable materials for thermal energy storage with temperatures below -40 °C commonly needed in these applications. The solid-liquid phase change of carbon dioxide has the potential to be conceptually considered for thermal energy storage in a special type of heat exchangers known as pillow plate heat exchangers. Characteristically, these heat exchangers can withstand very high pressures which is a technical requirement for carbon dioxide thermal energy storage. This dataset includes the data and figures related to the concept of thermal storage in the solid-liquid transition of carbon dioxide.

工业冷冻是一类高能耗工艺，且随着市场需求持续增长，其规模正不断扩大。这给电网带来了沉重负荷，在用电高峰时段尤为突出。为解决这一问题，热能存储（thermal energy storage）技术受到了广泛关注，但针对此类应用中普遍要求的-40℃以下温度区间的适配储能材料，目前仍存在研究空白。二氧化碳的固-液相变具备在一类被称为枕板式换热器（pillow plate heat exchangers）的特种换热器中应用于热能存储的理论潜力。该类换热器的典型特性为可承受极高压力，这恰好满足了二氧化碳热能存储的技术要求。本数据集涵盖了二氧化碳固-液相变热能存储相关概念的实验数据与配套图表资料。
