摘要
绿色环保天然工质二氧化碳以其优良的热物性成为热泵系统中合成工质最有潜力的替代物之一。介绍了二氧化碳热泵的原理、二氧化碳热泵在热水器上的应用以及二氧化碳热泵技术在国内外的发展现状,并且将不同品牌的二氧化碳热泵热水器进行了比较分析,最后通过计算将二氧化碳热泵热水器与其他热源的热水器的经济性能进行了比较分析。结果表明,二氧化碳热泵热水器无论在经济性方面还是在性能系统方面都要比其他热水器更有优势,因此发展空间很大。
As a kind of natural fluid, carbon dioxide is an attractive alternative to the synthetic fluids in heat pump systems, for it is environmental benign and owns good thermal properties. The principle of carbon dioxide heat pump was described. The application of carbon dioxide heat pump water heaters and the current status of carbon dioxide heat pump technology at home and abroad were described, too. Then a comparative analysis was made for different brands of carbon dioxide heat pump water heaters. Finally, a comparative analysis of economic performance between carbon dioxide heat pump water heaters and water heaters with other heat sources was carried out by calculating the annual consumption costs. The results show that carbon dioxide heat pump water heaters have more advantages than other water heaters in both economic aspect and performance systems, so they have very large space for development.
