热泵型蓄能空调蓄热性能测试及经济性分析

根据蓄能空调系统自身的特点,建立了蓄能空调的蓄热装置(双盘管蓄热水槽)蓄热过程的物理模型并结合蓄能槽的结构特点进行机组性能测试及能耗分析。结果表明,采用将释热盘管安装在蓄热槽上部并将释热盘管的直径设计为小于蓄热盘管直径的方法,可以使释热过程更加有效进行,并能改善传统单盘管分层严重的现象。在测试冬季三种运行工况性能系数均值的基础上,通过建立投资回收期模型的数据分析,得出其具有良好的经济效益。

Heat storage performance research and economic analysis on heat pump air conditioning

According to the characteristics of energy storage air conditioning system, physical model of regenerative process for the energy-storage air conditioning heat storage device (double coil heat storage water tank) was established in this paper. Performance testing and energy consumption analysis were completed combing with the structure characteristics of the energy storage tank .The results showed that the method which put the heat coil installed in the upper part of the heat storage tank and made the heat releasing less than the diameter of the coil heat coil diameter can make the heat release process more effective than traditional, and the double coil immersion heat storage tank can change the traditional single coil stratified phenomenon. Dates analysis by establishing a payback period mode of investment confirms that it has good economic efficiency.
