| 中文摘要: |
| R290作为一种自然工质，其臭氧层破坏系数ODP和地球变暖系数GWP值均接近于零，环保性能显著。为探索R290应用的可行性，在同一热泵空调热水器中进行了R290与R22的性能对比实验。实验研究结果表明：采用R290，机组的能效比COP及其运行性能明显优于相同条件下使用R22的机组。由此可见，R290作为热泵空调热水器的制冷剂不仅能完全替代R22，节能环保，其热物理性质特别适合热泵热水器应用，具有十分广阔的应用前景。 |
| 英文摘要: |
| R290 is a natural and environment-friendly refrigerant with its values of the ozone layer depletion and global warming coefficients (ODP and GWP) close to zero. To explore the feasibility of application of R290 to the heat pump water heater, an experimental performance comparison between R290 and R22 was carried out on the same water heater. Experimental results showed that the COP and the operation performance of the water heater with R290 are significantly better than the heater with R22. Therefore, as an environment-friendly refrigerant with thermophysical properties particularly suitable for the heat pump water heater, R290 can completely replace R22 and has promising application. |
