摘　　要：为减少严寒地区生活热水制备过程中的能源消耗,以CO_2热泵热水器为研究对象,建立了采用跨临界循环方式的CO_2热泵热水器的稳态仿真模型,模拟分析了CO_2热泵热水器在严寒条件下的运行性能。分析结果表明,在室外温度高于-13.9℃的条件下,CO_2热泵热水器能够正常运行,系统运行时COP高于2.67。文章的研究结果可为CO_2热泵热水器在严寒地区的推广提供参考。In order to reduce energy consumption in hot water preparation in severe cold areas,this paper taking carbon dioxide heat pump water heater as the study object,established steady simulation model in each parts of the heat pump unit and simulated the performance of the single stage compression cycle heat pump. The results showed that carbon dioxide heat pump water heater can operates above minus 13.9 degrees Celsius. The COP is above 2.67. This paper can provide references for applications and promotions of carbon dioxide heat pump water heater in severe cold areas.
