Feasibility Analysis of Phase Change Materials Applied In Solar Heating System

搭建太阳能供暖实验平台,以太阳能集热器作为系统集热组件,水箱作为蓄热组件,风机盘管作为散热末端;建立系统的数学仿真模型并通过实验验证其正确性;目前太阳能供暖应用广泛,但其依然存在温度波动大、太阳能利用率低、浪费能源等问题。针对上述问题,这里在传统太阳能供暖数学模型的基础上加入相变材料模块并模拟仿真,分析研究相变材料的加入对传统太阳能供暖系统的热影响,从而验证在太阳能供暖系统中加入相变材料的可行性,为工程实际提供参考依据。

Set up a solar heating experimental platform,with solar collector as the system heat collection component,water tank as the heat storage component,fan coil as the heat dissipation terminal;The mathematical simulation model of the system is established and its correctness is verified by experiments.At present,solar heating is widely used,but there are still problems such as big temperature fluctuation,low utilization rate of solar energy and waste of energy.Aiming at these problems,this paper on the basis of traditional solar heating mathematical model to join the phase change material module and simulation,analysis and study of phase change materials on traditional solar energy heating system heat affected,so as to verify the feasibility of solar energy heating system with phase change materials,provide a reference basis for the engineering practice.
