摘要	where environmental sustainability is at the forefront of societal concerns In the current global context, the imperative for clean, renewable energy sources has never been more pronounced. This study addresses the multifaceted challenges inherent in traditional greenhouse production systems, ranging from inefficiencies in energy utilization to the deleterious consequences of environmental pollution and the escalating costs associated with conventional energy sources. In response to these challenges, a groundbreaking renewable energy system has been conceptualized, ingeniously intertwining the utilization of solar and air energy. This innovative system, crafted with a keen consideration for the seasonal utilization of equipment, is explored through the lens of four distinctive operational strategies. A comprehensive comparative analysis is conducted, encompassing thermal dynamics, environmental impact, and economic feasibility, juxtaposed against traditional systems, both on typical days and over the course of a year. In the scrutiny of a typical day, the newly proposed system showcases a plethora of advantages over its traditional counterparts. The primary energy saving rate attains a commendable 24.67%, accompanied by a significant 23.22% reduction in carbon dioxide emissions and a noteworthy 17.04% decrease in operating costs. These figures underscore the system's capacity to efficiently harness renewable energy on a daily basis, thereby reducing reliance on conventional energy sources and concurrently mitigating environmental pollutants. Simultaneously, the pronounced reduction in operating costs renders the system economically appealing, presenting a sustainable solution for agricultural production. These findings highlight the immediate and tangible benefits that the new system can deliver to end-users, providing not only environmental advantages but also substantial economic incentives. Expanding the purview to an annual perspective, a more exhaustive examination of different operational strategies is undertaken. The primary energy saving rates corresponding to strategies 1, 2, 3, and 4 within the annual dimension are 60.23%, 70.43%, 70.53%, and 63.69% respectively, and the carbon dioxide emission reduction rates are 222.90%, 266.35%, 269.56% and 223.00% respectively. The operating cost saving rates are 227.12%, 272.38%, 302.56%, and 239.81% respectively, and the investment payback periods are 2.51 years, 2.35 years, 2.21 years, and 2.09 years respectively. Underscoring the system's rapid return on investment and enhancing its practicality and economic viability. Beyond the numerical data, the study delves into the nuanced energy characteristics of the system across both annual and typical day operations. This comprehensive understanding includes the positive environmental ramifications, such as diminished greenhouse gas emissions and heightened energy utilization efficiency. The innovative system not only represents a technological milestone but also furnishes the agricultural sector with a sustainable and eco-friendly solution. By elucidating the intricate interplay of energy dynamics, the study contributes to a holistic understanding of the system's impact on the environment and the agricultural ecosystem. A pivotal revelation of this study revolves around the operational duration and temporal differentials of the air-source heat pump, identified as pivotal factors influencing the overall system performance. This insight lays the foundation for future refinements and optimizations, as understanding the temporal intricacies can contribute significantly to enhancing the system's stability and adaptability. It also underscores the importance of continuous monitoring and fine-tuning to optimize performance under varying climatic conditions. In conclusion, the proposed renewable energy system not only achieves significant technological advancements but also boasts substantial economic and environmental advantages. Its adeptness in efficient energy utilization, coupled with notable economic savings and environmental amelioration, positions it as an optimal choice for the future of agricultural production. Through this research, we offer profound insights and a comprehensive theoretical framework, advocating for the widespread adoption of renewable energy in agriculture and infusing renewed vigor into the realm of sustainable societal development. The study not only contributes to the academic discourse on renewable energy but also provides actionable insights for practitioners and policymakers alike, paving the way for a more sustainable and ecologically responsible future in greenhouse production. © 2023 Chinese Society of Agricultural Engineering.
