蓄冷的冷源部分而进行的。

为平衡电网负荷、削峰填谷结合长沙市实行的谷峰电价政策，对冰

蓄冷空调系统与常规的空调系统的经济性进行分析比较从而确定了此建

筑适合应用冰蓄冷空调系统。通过对该建筑的冷负荷计算和冷负荷的分

布情况的分析，从而确定了冰蓄冷空调系统宜采用的运行策略，工作模

式和运行控制方案进而确定了其机组容量和蓄冰槽的容量。此冰蓄冷空

调系统采用的是风机盘管加新风系统，其中新风系统不负责室内负荷把

室外空气处理到室内的等焓状态点而送入室内。最后，在讨论冰蓄冷空

调系统的经济性时对冰蓄冷空调系统的能耗情况和经济性进行了整体的

分析和比较。

The graduation project designs air conditioning systems with ice storage for XX official building in Changsha City,

this design mainly is revolves the ice storage the cold heat sink partial to carry on.

For balances the electrical network load, to unify the valley peak electrovalence policy which Changsha implements, gathered the air-conditioning system with ice storage and the conventional air-conditioning system efficiency to the ice carries on the analysis comparison thus to determine this construction suited using the air conditioning systems with ice system. Through to this building cold load calculation and cold load distributed situation analysis, thus had determined the ice storage the movement strategy which the air-conditioning system with ice storage suitably used, the working pattern and the operating control plan then had determined its unit capacity and ice storage capacity. This air conditioning systems with ice storage is uses of the air blower plate tube adds the new atmosphere system, new atmosphere system is not responsible for in the room to shoulder the outdoor air processes to the room in some to enthalpy condition sends in the room.

Finally, air-conditioning system with ice storage when the discussion ice the efficiency air-conditioning system with ice the energy consumption situation and the efficiency has carried on the whole analysis and the comparison.

Key words: air-conditioning system, ice storage, economic

analysis,

building of office
