EXPERIMENTAL STUDY OF A LARGE TEMPERATURE DIFFERENCE THERMAL ENERGY STORAGE TANK FOR CENTRALIZED HEATING SYSTEMS

ABSTRACT
Decreasing the backwater temperature of the primary pipe in a centralized heating system is one successful way to increase the heating capacity and recover different kinds of industrial low-grade heat from the system. A new system combining an energy storage tank and a heat pump is introduced in this study as the key device in this system, so the temperature difference of this thermal storage tank could be over 25⁰C. To improve the thermal energy storage tank design, a mathematical model considering disturbance factor is given, an experimental system is built, and good agreement is found when the experimental results are compared with simulation results.
