空调水系统蓄能技术的实际工程应用潜力分析

Analysis on the application potential of actual engineering air conditioning water system energy storage technology

为了充分利用电网低谷时期的电能,在夜间进行蓄能是现有节能设计的普遍思路,采用蓄能系统能够显著的减少电费的支出。常规空调系统中只作为输送管道的空调水路系统,如果能够利用水管路系统中的存水进行蓄能,则可在常规空调系统的设计基础上较容易的实现水系统蓄能。选取云南昆明、湖北武汉和北京三地的实际工程,对其水系统蓄能潜力进行分析,以探讨这种设计思路的应用潜力。经过分析工程实例,总结出水系统蓄能量为0.006~0.011kWh/m^2,以及设计初期的评估公式和线算图。同时,在满足部分条件并在相应工程设计阶段进行足够分析的前提下,采用空调水管路系统蓄能具有一定的可推广意义。

In order to make full use of the power trough of the grid, energy storage at night is a common idea of existing energy-saving design. The energy storage systems can significantly reduce the cost of electricity. In the conventional air conditioning system, the air-conditioning water pipes convey cold water. If the water in the pipes can be used for energy storage, the water energy storage can easily achieve based on the design of the conventional air-conditioning system. Selecting the actual projects in Kunming, Wuhan and Beijing, this paper analyzes the energy storage potential of the water system and try to explore the application potential of this design idea. After analyzing the building examples, the author summarizes that the value of energy storage in the air-conditioning water system is 0.006-0.011 kWh/m^2 and the evaluation formula and nomogram for initial design. Meanwhile, it is considered that under some conditions and sufficient analysis in the corresponding design stage, there is certain promotion significance for energy storage in the air-conditioning water system.
