The invention discloses a
machine room energy efficiency optimization
simulation system and method based on digital twinning, and relates to the technical field of
machine room energy efficiency optimization. The
system comprises a model construction and
load analysis module, an equipment combination design module, an energy efficiency
simulation calculation module and an optimal scheme
adaptation and output module. According to the method, related parameters of a
machine room are collected to construct a digital twinborn
simulation model, different levels of load intervals are divided, a differentiated combination scheme composed of a high-
voltage fixed-frequency large cold source unit and a low-
voltage variable-frequency small cold source unit is designed for each interval, an energy efficiency optimal scheme is matched through simulation, a
correlation database is established, and a result is output. Dynamic
adaptation of the cold source equipment and the load interval is achieved, low-load energy efficiency attenuation is avoided, the full-working-condition energy efficiency of a machine room is remarkably improved, and reliable support is provided for optimal configuration of a cold
source system.
