Abstract

This article focuses on the energy-saving regulation of HVAC system under complex climate conditions. At present, climate change makes HVAC systems face challenges, and it is difficult for traditional control strategies to take into account multiple objectives. This article analyzes the influence of complex climate on load, equipment and operation, designs multi-objective energy-saving strategies, establishes an energy-saving-comfort-stability model and solves it with NSGA-II. The simulation results show that the strategy can reduce energy consumption and maintain good comfort and stability in different climate scenarios, but there is still room for optimization in some scenarios. After technical, economic and environmental feasibility analysis, it is adjusted and optimized. The research results provide an effective way for energy-saving regulation of HVAC system in complex climate, which is helpful to realize the synergistic improvement of energy saving, comfort and system stability.
