摘要(Abstract):
太阳能与热泵相结合的技术是新能源利用技术发展的一个重要方面,而以太阳能-热泵为热源的地板辐射供暖系统是利用太阳能向建筑物供暖的理想方案。介绍了该系统的组成方式与运行方式,建立了采暖房间热力过程的数学模型,设计了数学模型的数值求解方法,并针对所建立的太阳能-热泵热源地板辐射供暖系统中采暖房间的热力过程进行了数值计算。通过计算结果与实际测试结果比较表明,所建立的数学模型和数值求解方法能够用于模拟此种供暖系统的房间热力过程。
The technology combined solar energy with heat-pump is an important aspect of the new energy technology.The radiant floor heating system which takes solar energy-heat pump(SHP) as heat source offers suitable heating mode to residential buildings.the working pattern of this system is introduced.Furthermore,mathematic model of the heating room's thermodynamic process is set up,numerical method of this mathematic model is illustrated then.Comparing the practical testing results with the numerical simulation results,it can be concluded that this mathematic model can be adopted to simulate the heating room's thermodynamic process in this type of SHP source heating system.
