In this study, water supply characteristics ware analyzed under the condition of part load in the apartment house complex using a district heating source. And then, effects and limitations of the each heating system component were derived. For evaluation, real case of the apartment house complex using a district heating source was selected and then simulation with the real design data was performed. Simulation results show that over flow water supply has happened under the condition of part load in the traditional hydronic(flow) network and over flow rate becomes larger with the longer piping and smaller load. In conclusion, although pressure differential control valves are good for the hydronic(flow) balancing effect between two apartments in the same zone, they still can’t solve the over flow problem between each housing, especially to the upstairs. A flow limit valve also can’t make the each room hydronic(flow) balancing under the condition of part load. In addition, results show that a variable speed pump loses the flow control ability as it sets up with the pressure differential control valves, and the pressure control saves very small pump energy compared with the high initial costs for VFD (Variable Frequency Drive). |
