摘要(Abstract):

针对冰蓄冷空调系统的主机优先和融冰优先控制策略,分析了不同策略下对主机容量的影响,以及两种策略下消耗的电量和电费比较。得出:对于一定的空调负荷,主机优先供冷时,随着主机供冷/峰值负荷的数值增大,主机容量增大,总耗电量减小,电费增大;融冰优先供冷时,随融冰供冷/峰值负荷的数值增大,主机容量下降,总耗电量增大,电费减少。
The effect of two control strategy on the chiller-capacity is analyzed and the comparison is made about the power consumption and the cost of electricity according to the chiller-priority control and the storage-priority control strategy on ice storage air-conditioning System.It is obtained that :for the same air-conditioning load,the chiller-capacity increases,a total power consumption reduces and the cost of electricity increases with the ratio refrigeration/peak load values increased in chiller-priority control strategy;the chiller-capacity reduces,a total power consumption increases and the cost of electricity reduces with the ratio refrigeration / peak load values increased in storage-priority control.
