Abstract：
Overviews the historic development of Chinese and overseas cooling load calculation methods and summaries the current status.Presents two advanced calculation methods—heat balance method and radiant time series method, and reviews the software development of cooling load calculation and building energy simulation. Points out that the new form and operating way of air conditioning systems change the process of heat gain conversing into cooling load, which leads to develop a new cooling load calculation method, so as to guide the design of new air conditioning systems.
