Abstract
Both geothermal heating and a fuel fired system using steady-state model and dynamic model were simulated based on heat load calculation, influence of radiator size on return temperature and mass flow was analyzed and radiator was selected, a sample district heating system network was set up, pressure and temperature drop of pipeline were calculated, and the system simulated. The results indicate that radiator size affect the indoor temperature significally, and, dynamic simulation model is an effective way to study the system performance, as the heating system can be controlled freely by controlling the maximum mass flow and radiator size.
