摘　　要：提出空调末端延时简化算法,计算最小、最大空调末端延时,以确定空调末端延时范围,为空调系统准确配合电网进行需求响应提供依据。结合算例,计算空调末端延时,分别采用传统模型、时滞模型对同一需求响应事件下的空调末端供冷量进行模拟。立管流速、支管流速一定时,建筑体形是空调末端延时的主要影响因素。时滞模型考虑空调末端延时的影响,空调末端供冷量变化比冷水机组停机和重启的时间有延迟,真实反映空调系统在参与需求响应时空调末端供冷量的变化。A simplified algorithm for air conditioning terminal delay is proposed to calculate the minimum and maximum air conditioning terminal delay, so as to determine the range of air conditioning delay and provide a basis for the air conditioning system to accurately cooperate with the power grid for demand response. Combined with the example, the air conditioning terminal delay is calculated, and the traditional model and the time lag model are used respectively to simulate the cooling capacity of the air conditioning terminal under the same demand response event. When the flow rate of the riser pipe and the flow rate of the branch pipe are constant, the shape of the building is the main factor affecting the air conditioning terminal delay. The time lag model considers the influence of the air conditioning terminal delay, and the change of the cooling capacity of the air conditioning terminal is delayed compared with the time of the shutdown and restart of the chiller, which truly reflects the change of the cooling capacity of the air conditioning terminal when the air conditioning system participates in demand response.
