复合制冷系统全局优化节能控制策略。首先,综合考虑了压缩机、冷却塔和风机的耦合关系,建立了以能耗最小为目标的冷库制冷系统全局优化控制模型;然后,通过对群体学习因子和个体学习因子进行自适应改进,提出了一种具有动态调节能力的自适应增强粒子群优化算法,以应对冷库制冷系统的动态负荷变化需求;最后,将所提出的AAPSO算法应用于浙江省某冷库制冷系统的节能优化控制,开展节能优化实验。结果表明:AAPSO算法较粒子群优化(PSO)算法有更高的鲁棒性、动态适应性和求解效率;与传统的规则控制策略相比,基于AAPSO算法优化后的冷库系统在稳定工况下全段平均节能率达到3.5%,在非稳定工况下全段平均节能率达到9.5%,证明了基于AAPSO算法的全局优化节能控制策略的有效性,可为冷库系统节能运行提供理论依据和实践参考。
To address the issues of high energy consumption
compromised food quality
and inability to adapt to variable load working conditions caused by traditional control strategies in cold storage refrigeration systems
a global energy-saving optimization control strategy for the R507A/CO
2
composite refrigeration system based on the adaptive-augmented particle swarm optimization (AAPSO) algorithm is proposed. First
the coupling relationships among the compressor
cooling tower
and fans are comprehensively considered
and a global optimization control model for the cold storage refrigeration system is established to minimize energy consumption. Then
by adaptively improving the group learning factor and individual learning factor
a dynamically adjustable AAPSO algorith
m is developed to address the dynamic load variation requirements of cold storage refrigeration systems. Finally
the proposed AAPSO algorithm is applied to the energy-saving optimization control of a refrigeration system in a cold storage facility in Zhejiang
China
and energy-saving optimization experiments were conducted. The results show that AAPSO algorithm outperforms PSO algorithm in terms of robustness
dynamic adaptability
and solution efficiency. Compared with traditional rule-based control strategies
the cold storage system optimized based on the AAPSO algorithm achieves an average energy-saving rate of 3.5% across the entire load range under stable operating conditions and 9.5% under non-stable operating conditions. These findings demonstrate the effectiveness of the global energy-saving optimization control strategy based on AAPSO algorithm
providing theoretical guidance and practical reference for the energy-efficient operation of cold storage systems.
