【中文摘要】 针对普通的定频空气源热泵热水器不能在宽负荷和宽温度条件下运行等缺陷,提出一种直流变频空气源热泵热水器.通过对样机进行实验,得出了制热量、功率、COP值、吸气温度、排气温度等性能参数随压缩机运行频率的变化规律。结果表明直流变频热泵热水器能在宽负荷、宽温度条件下稳定运行。 【英文摘要】 In this article, direct current frequency conversion air source heat pump water heater was brought forward according to the discharges of ordinary fixed frequency air source heat pump water heater, such as it can not run in the condition of wide road and wide temperature. Rules such as heating capacity, power, COP , inlet-temperature and outlet-temperature of compressor varies with frequency of compressor are derived by experiment on the model machine. The results indicate that current frequency conversion air source heat pump water heater can run stably in the condition of wide load and wide temperature. 【中文关键词】直流变频; 热泵热水器; 空气源 【英文关键词】 current frequency conversion; heat pump water heat; air source
