AB - Aiming at the problems of lack of energy in undeveloped areas with low  low-density residents and few heating users, and large heat loss, we  propose a heating energy vehicle connected with mobile energy storage to  assist the operation of district heating. Using paraffin-expanded graphite  as the phase change material for energy storage, this paper studies the  effect of expanded graphite on energy storage characteristics and finds that  10% expanded graphite can shorten the heat storage time and heat release  time by 50% and 36.4%, respectively. Two economic operation modes are  recommended for auxiliary district heating and synergetic coupling.
