太阳能热泵-低谷电与地板辐射采暖系统联合运营方式探讨

论述了太阳能热泵与低谷电作为地板辐射采暖热源的可行性和必要性,提出了一种利用太阳能和低谷电作为地板辐射热源采暖的方案,讨论了系统在冬季采暖期的运行方式.太阳能是一种无污染、无穷尽的自然能源,但具有不稳定和不可靠性,特别在冬季尤为明显.而低谷电作为太阳能的辅助能源,却可以有效弥补太阳能的不足.这两者结合具有节能、环保等优点.终端利用地板辐射采暖与太阳能热泵-低谷电系统提供热水温度特点一致,能够提高热泵制热性能系数,并且具有良好的舒适性和节能效果.因此,在我国北方地区,太阳能热泵与低谷电联合供暖在建筑领域值得推广和应用.

Combined Operation of a Solar Energy Source Heat Pump, Low-vale Electricity And Floor Radiant System

Feasibility and necessity of using solar energy,low-vale electricity as heat sources in a floor radiant system were analysed.A new heat pump system was presented and its operation modes in winter were discussed.The solar energy is tremendous,reproducible and no pollution,but unstable and uncertain,especially in the evening in winter.It can make up shortage of solar energy to use low-vale electricity as adjutant energy.So it possesses not only to save energy and protect environment but also to make up each disadvantages to the combined system.Hot water temperature supplied by the combined system accords with floor radiant heating system request,solar energy source heat pump has high COP,and floor radiant heating system has good comfort and saves energy.It should be extended and applied to the combined operating of solar energy source heat pump,low-vale electricity and floor radiant system in North of China.
