摘　　要：负荷计算是空调工程设计的基础。本文主要针对空调工程负荷计算相关的6个问题进行了探讨:1)空调工程设计负荷计算应包括哪些环节;2)如何准确定义空调区冷负荷和热负荷;3)新风冷负荷是否属于空调区负荷;4)冬季新风热负荷计算显热还是全热;5)空调系统设计冷负荷是否包括冷源及其输配系统的附加冷负荷;6)设计负荷计算与动态负荷计算的区别是什么。从标准/规范出发,结合专业书籍、设计手册和专题文献等资料,采用对比分析的方法,探讨上述问题相对准确合理的答案,为准确理解和进行空调工程冷/热负荷计算提供参考。Load calculation is the basis of air conditioning engineering design.This paper mainly focuses on six issues related to the air conditioning engineering load calculation,for example,(1)what should be included in the air conditioning engineering design load calculation,(2)how to accurately define the cooling load and heating load of the air conditioning space,(3)whether the outdoor air cooling load belongs to the air conditioning space load,(4)whether the outdoor air heating load is calculated by sensible heat or total heat in winter,(5)whether the design cooling load of air conditioning system includes the additional loads of the cool source and its distribution system,(6)what is the difference between design load calculation and dynamic load calculation.Starting from standards/codes,combining with the professional books,design manuals,special literature and other data,the relatively accurate and reasonable conclusions are obtained through comparison and analysis,which can provide a reference for accurate calculation of cooling/heating load of air conditioning engineering.
