中水源热泵地板供暖运行策略分析

摘要

为研究中水源热泵地板供暖系统的节能策略,以石家庄市某实际运行小区的中水源热泵地板辐射供暖系统为对象,引入室外综合温度的概念,综合考虑室外气温、太阳辐射热与风速等环境因子的影响,推导得出了地板辐射供暖系统质调节情况下,保证热用户舒适度的二次网供、回水温度调节公式.经实际运行测试,由该调节公式计算得出的二次网供、回水温度作为地板辐射供暖系统分时段质调节的依据,可以在满足热用户舒适度要求的情况下,取得良好的节能效果.中水源热泵系统与地板辐射供暖系统的结合及推广为城市集中供热提供了新思路.%The energy reservation strategy of floor radiant heating system powered by reclaimed water source heat pump is analyzed by taking an actual running floor radiant heating system in Shijiazhuang as research subject.Considering the influences of environmental factors of outdoor temperature,solar radiate heat and wind speed,in the calculation of supply and return water temperature in the secondary circuit,a comprehensive outdoor temperature is introduced to obtain the regulation formula that guarantee heat users' comfort level during the temperature regulation of floor radiant heating system.According to actual operation tests and the divided periods temperature regulation of the floor radiant heating system by the regulation formula of return water temperature in secondary circuit,the supply and return water temperatures calculated from the comprehensive temperature model not only can meet users' comfort level requirement,but also achieve good energy saving effects.The combination and popularization of reclaimed water source heat pump and floor radiant heating system provide new idea for urban centralized heating system.
