Numerical simulation of summer air conditioning load caused by heat transfer through energy saving hollow walls

Presents the calculation of outdoor meteorological parameters for summer air conditioning and solar irradiance and the numerical discretization of the meteorological parameters. Based on the finite volume method, calculates the air conditioning cooling load caused by heat transfer through the hollow walls and the cooling load temperature for several kinds of hollow walls for the summer standard design day, and compares them with those of normal walls of Ⅱ, Ⅲ and Ⅳ types.
