Testing and simulation of phase change wallboard for thermal storage in buildings

摘要

When linear alkyl hydrocarbons are formulated to change phase at near room temperature and are impregnated into gypsum wallboard,they can store large amounts of heat over the narrow range of temperatures typically encountered in buildings.This dampening effect could improve thermal comfort in interior spaces,delay the need for cooling until off-peak hours,and reduce the required size of mechanical cooling and heating equipment.
