Solar radiation has a great influence on indoor heat balance when simulating building thermal processes. For radiant heating / cooling systems, solar radiation has a great influence on indoor thermal environment and system efficiency. The correct solar heat distribution algorithm can more accurately predict energy efficiency and thermal environment and its comfort. In this paper, we summarize and summarize the algorithm of solar radiation incident in the room, analyze the advantages and disadvantages of each allocation algorithm and the degree of difficulty, and explain several typical allocation algorithms in detail. For different types of solar radiation indoors The suggestions for allocation are given, which can guide the selection of solar radiation distribution algorithm in simulation of building thermal process.
