摘　　要：为提高公共建筑太阳能空调系统的太阳能保证率,在传统太阳能空调蓄冷系统的基础上,将相变蓄冷技术应用在公共建筑太阳能空调系统中,并建立相应的数学模型。经软件模拟和实验测试,表明太阳能空调相变蓄冷系统数学模拟与实测数据吻合较好,验证了太阳能空调相变蓄冷系统的可行性和有效性。在该文案例中,与传统水蓄冷系统相比,相变蓄冷系统可使系统制冷季太阳能保证率提高17.5%。In order to improve the solar insuring rate of solar air-conditioning system in public buildings,a cold storage method by using phase change material is presented in this paper,which is based on traditional solar air-conditioning system of public buildings,and the mathematical model of this method is established. The current results show that the system model established in this paper is in good agreement with the measured data by simulation and experimental test and the feasibility and effectiveness of the system are verified. Compared with the traditional chilled water storage system in this case,this system is expected to increase the solar insuring rate by 17.5% in refrigeration season.
