二氧化碳作为一种天然制冷剂，具有安全、经济、环保等优点，可用于热泵和制冷系统，特别是跨临界循环。自20世纪90年代初二氧化碳跨临界循环开始以来，理论和实验研究以及商业系统开发不断改进，使跨临界系统性能达到与传统热泵系统相似的水平。本文综述了跨临界二氧化碳热泵和制冷系统的研究进展。本文首先介绍了二氧化碳作为制冷剂的历史和主要应用。其次，对超临界纯二氧化碳润滑剂和含聚亚烷基二醇（PAG）润滑剂的性能进行了分析和评述。第三部分首先分析了基本二氧化碳跨临界循环的一些特点，如最佳系统压力、最大压力等，然后对几种新型跨临界循环进行了性能分析和比较。最后对跨临界CO2热泵系统的研究现状进行了综述，包括系统的主要组成部分和研究热点，如传热和膨胀机等。
As a natural refrigerant, carbon dioxide is safe, economic and environmentally sustainable which can be used in heat pump and refrigeration systems especially in transcritical cycles. From the early 1990s, in which the carbon dioxide transcritical cycle began, theoretical and experimental researches, as well as commercial system development, has improved to make the transcritical system performance to a level similar to that of conventional heat pump systems. This paper presents an overview of transcritical carbon dioxide heat pump and refrigeration systems. The paper introduces a summary of the history and main application of carbon dioxide's use as a refrigerant firstly. Secondly, the properties of supercritical pure carbon dioxide and that containing polyalkylene glycol (PAG) lubricants are analyzed and reviewed. In Section 3 the paper began with an analysis of some special characteristics of the basic carbon dioxide transcritical cycle such as the optimum system high pressure and so on, and then followed by a performance analysis and comparison of several novel transcritical cycles. The study finally presents a review of research on transcritical carbon dioxide heat pump systems, which covers the main components and research hotspots, such as heat transfer and expander.
