摘要
天然环保型工质CO_2在系统采用跨临界循环后,与传统制冷剂相比具有独特的优点。基于可持续发展观,CO_2成为热泵热水器系统最有潜力的替代工质之一。近15年来,挪威等欧洲国家、日本和美国对CO_2热泵热水器系统进行了广泛深入的研究。本文详细介绍了CO_2热泵热水器样机的研究状况,总结了核心部件压缩机和换热器的研发现状,并探讨了有待进一步开展的研究内容。
As a natural working fluid, CO2 with transcritical cycle has several unique advantages when compared with conventional refrigerants. Based on sustainable development, CO2 emerges as one of the most likely alternatives to the synthetic fluids in heat pump water heaters. Over the past 15 years, extensive and intensive research on CO2 heat pump water heater system has been undertaken by research groups in Norway, Japan, America, etc. The research status of CO2 heat pump water heater prototypes was presented in detail. The development of key components, compressor and heat exchanger, was described, and further potential work required was specified.
