冰蓄冷空调系统控制策略的比较探讨

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.

Study on Comparison of Control Strategy on Ice Storage Air-conditioning System

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.
