The invention discloses a building
composite phase change material intelligent matching and optimizing method based on a large
language model, and belongs to the technical field of
building energy saving and intelligent
material design. Basic thermophysical property data,
building environment parameter data and user demand data are collected; a deep
reinforcement learning technology is utilized to construct an intelligent model based on a deep Q
network strategy, and generated data samples are integrated into a thermophysical property
database; outputting a candidate material combination recommendation scheme by adopting a large
language model; evaluating the candidate material combination recommendation scheme by using the semantic tag vector and a sorting engine to obtain a performance
evaluation result; generating a performance evaluation report according to the
simulation model; a multi-agent negotiation
algorithm is adopted, cross-regional
thermal control performance is optimized, a multi-dimensional
performance comparison diagram and tuning suggestions are generated, correction information of designers is recorded, optimization is carried out, and feedback is provided in a self-adaptive mode. According to the method, the building
composite phase change material combination is screened, cross-regional
thermal control is optimized, adaptive schemes and suggestions are output, and the self-
adaptive optimization capability of the
system is improved.
