| Abstract: | An indirect hot water heating system dynamic model was developed by applying for energy and mass balance principles.This model was employed to simulate and analyze the influence such as the ratio of makeup water,heat transfer area of heaters and heat exchangers,outside temperature,solar radiation,internal gains,water mass flow rate and supply water temperature of heaters for the performance of the system and the user.Based on different control system configuration,system operation and energy consumption of six types of control strategies were tested and analyzed.Simulation results from the control systems showed that the control strategies based on user side demand could achieve the targets of energy saving for the system and thermal comfort for the end users. |
