摘要 本文主要从能源角度对现有常规热泵热水器热气旁通除霜和热气逆向除霜进行了比较;介绍了通过采用除霜周期内最大平均制热量及最大平均能效作为热气逆向除霜进入点的新控制方案;通过与常规时间-温度控制除霜方法进行了实验对比,从实验数据对比中得出,采用平均制热量最大值法能够在一个除霜周期中提高制热量10.2%;采用最大平均能效法能够提高能效2.8%。 本文主要从能源角度对现有常规热泵热水器热气旁通除霜和热气逆向除霜进行了比较;介绍了通过采用除霜周期内最大平均制热量及最大平均能效作为热气逆向除霜进入点的新控制方案;通过与常规时间-温度控制除霜方法进行了实验对比,从实验数据对比中得出,采用平均制热量最大值法能够在一个除霜周期中提高制热量10.2%;采用最大平均能效法能够提高能效2.8%。
