Auteurs : WANG Z., PENG Y., SHI L.

Résumé

For one typical geothermal district heating system (GDHS) in Xianyang city, using DeST software to calculate seasonal heating loads of one residential building community, establishes a general calculation model of the system operation energy consumption for 4 types of system configuration mode for the GDHS, including only plate heat exchanger mode, plate heat exchanger + natural gas boiler (for peak load demand) mode, plate heat exchanger + heat recovered type heat pump +natural gas boiler (for peak load demand) mode, plate heat exchanger + heat recovered type heat pump (for peak load demand) mode, compiles the modelling program based on VB, calculates and analyses influence of system mode, load variation, production well water temperature and terminal heating pattern on the system energy efficiency, and gives the maximum integrated system energy efficiency mode for the GDHS .
