摘要(Abstract):
研究了采用相变蓄能除霜方法的不同蓄能运行模式下空气源热泵的运行状况和室内热舒适情况,在搭建的试验台进行了对比试验,得到了供热和除霜运行参数、室内环境参数和热舒适评价的结果。从而得出蓄能除霜可以解决空气源热泵换向除霜过程中因热量不足而导致的各种除霜问题,且蓄能除霜提高了除霜过程中系统的可靠性和室内热舒适度。并且进一步得出了并联供热和蓄能换热除霜模式在提高热舒适度方面优于串联供热和蓄能换热除霜模式。并联供热可以使用在部分负荷工况下,而串联供热可以使用在全负荷工况下。
It was based on building an experiment rig,to compare between heating and defrosting operation parameters,indoor environment parameters and the thermal comfort evaluation,and conduct an analysis of operation condition and the indoor thermal comfort of three sets of air source heat pump thermal energy storage( TES). It indicates that the use of the energy storage defrosting can solve the problems caused by insufficient heat during reverse-cycle defrosting and improves the reliability of the system in the process of defrosting and indoor thermal comfort. Furthermore,compare to the series heating and energy storage heat defrost mode,parallel heating and energy storage heat defrost mode has a greater advantage in improving thermal comfort.. Parallel TESbased heating can be used under partial load conditions,the serial TES-based heating can be used under full load conditions.
