【摘要】：以多联机空气源热泵相变蓄能除霜系统为研究对象,采用实验研究的方法对采用翅片管型和螺旋盘管型相变蓄能器的多联机空气源热泵除霜系统的蓄能过程进行实验分析。研究结果显示:室内机全负荷状态下,相变蓄能器在供热过程中蓄热,螺旋盘管型蓄能器与翅片型蓄能器完成蓄热分别需要6.00和33.00 min。从整个供热周期来看,翅片型蓄能器对供热过程的影响更小,蓄热过程会引起室内平均进出风温差降低4℃、平均供热量降低6 kW,系统结霜时间缩短8 min。
[Abstract]:Taking the phase change defrosting system of multi-on-line air-source heat pump as the research object, the experimental analysis of the defrosting process of the multi-on-line air-source heat pump defrosting system using finned tube type and spiral coil type phase change accumulator is carried out. The results show that the heat storage of the phase change accumulator takes 6.00 min and 33.00 mins respectively for the spiral coil accumulator and the finned accumulator under the full load state of the indoor unit. From the whole heating cycle, the finned accumulator has less influence on the heating process. The heat storage process will cause the average indoor air temperature difference to be reduced by 4 鈩，
