摘要
以带有自主设计的相变蓄热器的空气源热泵系统作为研究对象,通过实验研究的方法,对该系统运行模式、控制策略以及与常规逆循环除霜性能的差异进行了验证。研究结果表明:空气源热泵相变蓄能除霜系统具有良好的运行模式和控制策略,能够很好的解决逆循环除霜时无低位热源和系统可靠性差的问题,缩短除霜时间约1/3,提高了室内送风温度,改善了室内舒适度。
The ASHP system with phase change energy storage defrost device was established and researched experimentally. The system operating mode, control strategy and the differences with conventional reverse cycle defrost were researched. The experiment results show that the ASHP system has good operating mode and control strategy, can solve the problems existed in the conventional reverse cycle defrost well, improve indoor comfort well.
