按板式换热器的数量对并联蓄冰系统、按泵的数量对串联蓄冰系统进行了分类 ,并对常见的蓄冰系统水泵设计方法进行了分析和评价。针对并联单板式换热器系统传统设计方法存在的问题 ,提出了泵的改进设计方法 ;对于串联系统 ,则提出采用制冷机旁通、多级泵和变频泵的方法使系统配置更加合理
According to the number of plate heat exchangers for parallel ice storage system, the series ice storage system is classified according to the number of pumps, and the common design method of ice storage system pumps is analyzed and evaluated. Aiming at the existing problems in the traditional design method of the parallel single-plate heat exchanger system, an improved design method of the pump is put forward. For the series system, the method of using the bypass of the refrigerator, the multi-stage pump and the variable frequency pump is proposed to make the system more reasonable
