摘　　要：干燥工艺在工、农业生产中耗能巨大,研究和应用实践表明相比于其他干燥技术,热泵干燥技术具有较好的节能效果和经济效益。CO_(2)作为自然工质对环境友好,而且跨临界CO_(2)循环放热过程具有明显的温度滑移,相比常规工质冷凝温度恒定的亚临界循环,更适合用于热泵干燥工艺。本文阐述了跨临界CO_(2)热泵干燥系统的研究现状,从CO_(2)热泵干燥应用的可行性、系统模型建立与关键参数分析、实验研究及系统优化等方面进行了深入讨论,总结各种CO_(2)热泵干燥系统优化方式的优缺点,提出了目前跨临界CO_(2)热泵干燥系统研究中存在的问题,为CO_(2)热泵干燥技术未来的研究应用提供参考。The drying process consumes large amounts of energy in industrial and agricultural production.Research and practical applications show that compared with other drying technologies,the heat pump drying technology has better energy-saving potential and economic benefits.As a natural working medium,CO_(2)is environmentally friendly.The transcritical CO_(2)cycle has a clear temperature glide,which is more suitable for heat pump drying than the subcritical cycle with a constant condensing temperature of using conventional working fluids.In this paper,the research status of the transcritical CO_(2)heat pump drying systems is described.The feasibility of the application,system model establishment and key parameter analysis,experimental research,and system optimization of CO_(2)heat pump drying system are discussed in depth.The advantages and disadvantages of various CO_(2)heat pump drying system optimization methods are summarized.Existing limitations in the current research of transcritical CO_(2)heat pump drying systems are proposed,thereby providing a reference for future research applications of CO_(2)heat-pump-drying technology.
