Energy saving technology analysis of air conditioning water system in a building in Xiamen

A building project in Xiamen adopts inner melt ice cool storage system in series upstream of main refrigerating machine with base load and large temperature difference air conditioning chilled water system with variable flow secondary water pump. Analyses the energy saving technology of air conditioning water system of this project. Presents the rationality and problems of secondary water pumping distribution system and the selection of large temperature difference respectively. Based on the applicability analysis of large temperature difference between air conditioning equipment terminals and water chillers, compares the two working conditions(supply/return water temperature of 6 ℃/12 ℃ and 5 ℃/13 ℃), and calculates the energy consumption of air conditioning water system. Reasonably selects the chilled water supply and return water temperature for this project.
