阐述了该机组的结构与特点，提出了一种综合考虑相变材料利用率、空气处理效果满意率和运行费用节省率来确定系统最佳蓄冷量和运行方案的方法；通过经济分析提出了临界附加初投资的概念，可作为是否应该投资的判据；作为算例，对该机组的经济性及其在北京地区的使用效果作了全年模拟分析。
The structure and characteristics of this unit are expounded. A method of considering the utilization ratio of phase change material, the satisfactory rate of air treatment effect and the saving rate of operation cost is proposed to determine the optimum cooling capacity and operation plan of the system. The critical value The concept of additional initial investment can be used as a criterion of whether investment should be made or not. As an example, the annual economic simulation of the economy of the unit and its effect in Beijing was made.
