【摘要】 本文利用氨/水作为吸收工质对,搭建了吸收压缩式热泵试验台,试验台热泵功率50KW,氨水充灌浓度60%,压缩机压缩比4,热源温度40℃,热水出口温度70℃,实验测试了压缩机压缩性能对系统稀溶液浓度、浓溶液浓度、制热温差和COP的影响,测试结果表明:在热源温度为40℃的情况下,系统稀溶液浓度随着压缩比的增加而降低;系统浓溶液浓度随着压缩比的增加而增加;系统制热温度差随着压缩比增加而增加;随着压缩比的增加,系统的COP先增加后减小,在压缩比为3.2-3.6时,系统的COP大于4。在本实验工况下,当压缩比等于3.4时,系统COP取得最大值4.4。更多还原

【Abstract】 The paper built an absorption-compression integrated heat pump experimental platform.Ammonia-water is used as absorption working pairs.The power of the heat pump is 50KW,the concentration of the filled ammonia is 60%,the compression ratio of the compressor is 4,the temperature of the heat source and outlet of hot water is 40 degrees centigrade and 70 degrees centigrade.The effects of different concentration of dilute solution,different concentration of strong solution,heating temperature and COP on the system performance are investigated..After a lot of experiments,it is proved that in the case of the temperature of the heat source is 40 degrees centigrade,the concentration of the dilute solution declines with the increasing of compression ratio,,the concentration of the strong solution increases with the increasing of compression ratio,the heating temperature increases with the increasing of compression ratio,with the increasing of compression ratio,the COP increases in the beginning and then declines.When the compression ratio is 3.2-3.6,the COP is above 4.Under the condition of this experiment,when the compression ratio is 3.4,the COP obtains the maximum 4.4.更多还原
