基于某建筑的全年逐时能耗模拟数据，通过MATLAB软件的非线性结构优化功能对热泵系统中多台机组的运行负荷配比方案进行优化，提出最优的机组运行负荷配比方案。研究表明：在逐时负荷大于单台或多台机组装机容量时，随着逐时负荷增加到运行机组总装机容量的70%左右时，各台机组运行负荷占各机组额定容量的百分比趋于相同；热泵系统采用最少台数的机组运行可有效提高系统的运行性能。根据部分负荷下机组负荷配比原则，给出机组在不同日负荷特性曲线下的运行方案。

Based on the wholeyear hourly energy consumption simulation data of a building,by utilizing the nonlinear structural optimization functions of the software Matlab,optimized were the versions of the proportions of the operation loads distributed to various units in a heat pump system and proposed was an optimum version.It has been found that when the hourly load is greater than the installed capacity of a single or several units or increases to around 70% of the total installed capacity of the units in operation,the percentages of the operation loads occupied by various units in the rated capacity of each unit tends to be identical.To put into operation of the minimal number of the units in the heat pump system can effectively enhance the operation performance of the system.According to the principles for proportions of loads distributed to units under the condition of a partial load,the operation versions under various daily load characteristics were given.
