Hi @忠宇
If there is no pre-existing model available for the thermal dynamics of a solar heating system, it is possible to manually derive the governing differential equations.
Could you please provide the relevant excerpts or references from solar energy textbooks or engineering handbooks that detail the applicable differential equations? Having access to those source materials would allow me to provide a more informed and comprehensive response.
%% Solar heating system
function dT = solarHeating(t, T)
% parameters
param1 = ...;
param2 = ...;
param3 = ...;
% differential equation
dT = [eqn1;
eqn2];
end
