摘要
为研究以太阳能为低温热源的供热运行特点,建立了太阳能热泵系统试验台及试验台测量系统,使用数据分析软件处理不同工况下的试验数据,分析了蒸发和冷凝温度对吸热量、制热量、压缩机状态、系统COP的影响。结果表明,太阳能热泵系统在运行期间节能效果明显,蒸发温度的增大有利于提高太阳能热泵系统的工作性能。
In order to study the performance of solar heat pump system which takes solar energy as low temperature source, ：solar heat pump system and measurement system are established. And the experimental data is dealt with by data analysis software. Then it analyzes the influence of evaporating and condensing temperature on heat output, heat absorp tion, state of compressor and coefficient of performance. The results show that the solar heat pump system has energy saving effect during the operation and the increase of evaporating temperature will be helpful to improve the performance of solar ]heat pump system.
