摘要(Abstract)：
探讨了以太阳能-热泵为热源的地板辐射供暖系统的组成方式与运行方式,建立了系统间歇运行方式下采暖房间热力过程的数学模型,研究了系统在间歇运行方式下采暖房间的热力过程。数值计算结果表明,以太阳能-热泵为热源的地板辐射供暖系统采用间歇运行方式是可行的。
A research about the radiant floor heating system which takes solar energy-heat pump (SHP) as heat source is made. The system composition and the working patterns are discussed. The thermodynamics process model of the heating room serviced by this type of system with intermittent operating mode is set up. The numerical simulation results of the heating room's thermodynamics process shows that it is feasible to adopt the intermittent operation mode in the SHP source heating system.
