Model-based predictive control optimization of chiller plants with water-side economizer system

Chengliang Fan et al.

Summary: This study proposes a model-based predictive control (MPC) method to optimize multiple parameters of the water-side economizer (WSE) system for energy saving. The results show that the hourly optimization strategy can achieve a maximum energy saving potential of around 14.3%, followed by the daily optimization with 12% energy savings. The difference in energy consumption between the other three optimization frequencies was small. Although multi-parameter optimization can save more energy, it requires significant time and computational resources.

A sustainable optimal biomass waste-driven CCHP system to boost the nearly zero energy building concept

Amir Ebrahimi-Moghadam et al.

Summary: The aim of this work is to design a sustainable tri-generation system driven by a biomass externally-fired gas turbine cycle and utilizing a double-effect absorption chiller/heater. The study develops a robust framework based on energy, eco-exergy, and environmental analyses to evaluate the reliability of this proposal. An innovative optimization approach is used to determine optimal sizing and operating conditions, combining an Artificial Neural Network and multi-criteria Salp Swarm Algorithm. The results demonstrate the system's ability to meet the electrical, heating, and cooling demands of a case study building, with the mass flow rate of MSW and compressor pressure ratio identified as the most influential variables on system performance.

Optimization of a weather-based energy system for high cooling and low heating conditions using different types of water-cooled chiller

Yuzhu Chen et al.

Summary: A weather-based energy system configuration is proposed in this study. By optimizing the capacities of different devices with the goals of energy saving and increasing renewable energy utilization, the ideal system configuration is found. The results show that increasing energy saving ratio improves cost saving benefits, but reduces the renewable energy penetration rate.

Multi-objective optimization of CCHP system with hybrid chiller under new electric load following operation strategy

Djamal Eddine Ghersi et al.

Summary: A new electric load following strategy, NELF, was developed for hybrid chiller based CCHP systems and found to be the best choice in terms of reducing primary energy consumption, annual total cost, and carbon dioxide emission. Performance of CCHP systems and operation strategies were compared, with NELF showing better energetic, economic, and environmental performance under optimized conditions.
