摘　　要：研究变频离心式制冷机组的经济运行控制方式。介绍了经济运行控制理论原理。通过将经济运行控制理论与相变材料蓄冷空调的有效结合,实现了主机始终运行于特定的节能负荷区间,在最大COP工况下高效运行。根据编制的模拟控制软件,分析了以经济运行控制的相变材料蓄冷空调与以变频离心机为主机的常规空调系统的经济性,认为前者较后者每年节约41.3%的运行费用。指出经济运行控制软件的实现,突破了冰蓄冷系统省钱不节能的局限,达到了移峰、节能的双重目的。The economic operation control methods for the variable frequency centrifugal refrigeration unit are studied, and with the help of the cool accumulation air conditioner using phase change material, the main engine can operate within the energy-saving load range. Based on the simulation control software, the economy of the phase change material-used cool accumulation air conditioner under economic operation control and that of the conventional conditioning system using the variable frequency centrifugal machine as its main engine are compared. Results show that the former can save 41.3% cost of the latter one in one year.
