摘　　要：积极应对气候变化已成为全球共识,在制冷、空调等领域,温室效应指数较高的氟利昂工质将逐渐被限制使用,天然工质二氧化碳冷热供应技术越来越多地应用于相关场景。本文概述了跨临界二氧化碳循环的基本原理和优势,并整理了跨临界二氧化碳冷热供应技术在热水器、食品冷冻冷藏、酒店商超、人工冰场等领域的国内外应用案例,旨在为二氧化碳利用技术的推广应用提供参考。Active response to climate change has become a global consensus,the freon with high Global Warming Potential will gradually be restricted in the fields of cooling and air conditioning,and the carbon dioxide as the natural working fluid for heat and cooling supply technology has been largely used in related scenarios.In this article,we present an overview of the fundamental principles and benefits of the transcritical carbon dioxide cycle,and sorts out the domestic and foreign application cases of transcritical carbon dioxide as the working fluid for heat and cooling supply technology in water heater,food refrigeration,hotel,supermarket,artificial ice rink and other fields,aiming to provide reference for the application promotion of carbon dioxide utilization technology.
