Guangzhou Maritime University’s Chiller Optimization Slashes Energy Use by 18.92%

In the world of maritime and high-rise buildings, energy efficiency is a hot topic, and a recent study out of Guangzhou Maritime University is making waves. Jiankun Yang, a researcher at the School of Future Transportation, has developed a novel approach to optimize the energy consumption of central air-conditioning systems in super high-rise buildings. The findings, published in the journal ‘Buildings’ (translated from Chinese), could have significant implications for the maritime sector, where energy efficiency is paramount.

So, what’s the big deal? Well, Yang and his team have proposed a hybrid integer optimization method based on the Whale Optimization Algorithm (WOA) to improve the energy efficiency of asymmetric central air-conditioning chiller systems. In simpler terms, they’ve developed a smart way to control the cooling systems in skyscrapers, making them work more efficiently and save energy.

The team constructed high-precision models of the energy consumption of all equipment in the chiller system using a three-hidden-layer multilayer perceptron (MLP) chiller model and a gradient boosting regression cooling tower model. They then integrated discrete on-off states and continuous operating parameters into WOA, designing a three-layer constraint repair mechanism to ensure the physical feasibility of the optimization process and the safe operation of equipment.

The results were impressive. The optimized system’s energy efficiency ratio (EER) increased by up to 15.01% in low-load scenarios, with energy savings of up to 12.91%. Annual rolling optimization results showed an average EER increase of 16.1%, with energy savings ranging from 8.59% to 18.92%. As Yang puts it, “The optimization method proposed in this paper meets the minute-level real-time scheduling requirements of building automation systems and provides an implementable solution for energy-saving optimization of central air conditioning chiller systems in super high-rise buildings.”

So, what does this mean for the maritime sector? Well, energy efficiency is a critical factor in the design and operation of maritime vessels. The principles behind Yang’s research could be applied to the cooling systems of ships, helping to reduce energy consumption and lower operating costs. Moreover, the use of advanced algorithms and real-time scheduling could improve the overall efficiency of maritime operations.

The commercial impacts of this research are significant. Maritime companies could see substantial savings on energy costs, making their operations more competitive. Additionally, the reduced energy consumption could help maritime companies meet increasingly stringent environmental regulations.

In terms of opportunities, the research opens up new avenues for collaboration between the maritime and construction sectors. The technologies and methodologies developed for high-rise buildings could be adapted and applied to maritime vessels, fostering innovation and growth in both industries.

In conclusion, Jiankun Yang’s research represents a significant step forward in the field of energy-efficient building systems. The maritime sector would do well to take note and explore the potential applications of this innovative approach to energy optimization. As the world continues to grapple with the challenges of climate change and energy sustainability, such advancements are not just welcome but necessary.
