Phase Change Energy Storage with Composite Plates Optimized Structure for Maximizing Energy Storage Potentials

Abstract

Abstract-The vacuum absorption method was used to fabricate the phase change material particle (PCMP) in a vacuum heating roller box, and then PCMPs were pressed to form the composite phase change energy storage plate (CPCESP) through a mould. Tests about the thermal conductivity and the heat storage and release capacity of CPCESP with different aluminum (Al) mass fractions were conducted; meanwhile, their fitting curves were obtained. According to the linear optimization principle and different actual situations, Al mass fractions, thermal conductivity and heat storing and discharge capacity per unit mass for CPCESP can be achieved, in order to optimize CPCESP heat storage and release performance.
