摘要
冰蓄冷系统作为有效的储能手段,可以有效解决高峰时期用电过多问题.本文基于一个实际的工程案例,对冰蓄冷系统在过渡季节,单次蓄冰一天,单融冰两天的工况进行了分析研究.结果表明,系统单融冰工况运行稳定,主机侧设计工况与实际运行工况吻合,末端侧则存在差异.另外,结合室外的温湿度情况,可以给整套冰蓄冷系统的运行策略提供有效的前馈.本文的研究为设计师对冰蓄冷系统的设计以及系统投入使用后的运行策略提供了一定的建议.
The energy consumption of air conditioning and refrigeration occupies a part of the overall energy consumption of buildings.As an effective way of energy storage,the ice storage system can effectively solve the problem of excessive power consumption in peak period.Based on a practical engineering case,during the transitional season,the working conditions with ice storage for one day and ice melting for two days were analyzed and studied.The results show that the system operates stably under the ice melting condition and the design conditions of the water chiller side agree with the actual operating conditions,whereas the difference exists at the terminal.In addition,in combination with the outdoor temperature and humidity,it can provide an effective feedforward for the operation strategy of the ice storage system.In this paper,some suggestions were proposed for the designer to design the ice storage system and the operation strategy after the system is put into operation.
