Discussion on some issues of cooling/heating load calculation of air conditioning engineering

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.
