Abstract：
Conducts a comprehensive study on integrated part-load value (IPLV) by characterizing the necessity of the modification of the IPLV formula, and improves the calculation method. Additionally, specifies the calculation method of the IPLV formula associated with its procedures, and proposes a method to obtain the weighting coefficients required in the IPLV formula. By performing calculations on the IPLV formula based on the typical public building model database, achieves a revised IPLV formula which is suitable for the current performance level and features of the chiller in China.
