摘要
对现有的空气源热泵热水器系统部件提出了优化目标与方向,并进行相应计算和实验验证。通过分别对热泵工质充注量、冷凝盘管长度以及系统匹配问题的研究,结合实验结果证明了经过优化后,热泵热水器系统的性能COP显著提高,并且稳定性得到改善。
The system optimization of the air sourced heat pump water heater （ASHPWH） was presented including calculating and testing. The capillary tube length, the filling quantity of refrigerant, the condenser coil tube length and system matching are discussed accordingly. The testing results showed that the system performance COP could be improved obviously after system op optimization.
