北方地区多能源耦合在集中生活热水系统中的应用

Application of multi energy coupling in centralized domestic hot water system in North of China

随着国家双碳目标的控制要求,非传统能源在集中生活热水系统中的应用占比将会越来越大。目前,生活热水系统中非传统热源利用较多的是太阳能、地源热泵、空气源热泵、水源热泵等。太阳能由于受白昼和天气变化的影响,其不稳定性和非连续性一直是其被很好利用的一个制约因素。设置有集中生活热水系统的工程,若采用太阳能热源就必须设置相应的辅助热源,辅助热源是保障系统稳定的最重要屏障。但从经济性而言太阳能又是其他几种非传统能源所无法比拟的,随着节能要求的进一步提高,采用集中非传统能源和传统能源的组合,在一段时间内势必是北方地区集中生活热水系统的能源利用的一种主流。高效的利用好非传统能源、传统能源的组合,使其系统高效耦合,才能真正达到系统的最大化节能、稳定、安全和可靠。

As our national dual carbon target controls,the use of non-traditional energy sources in centralized domestic hot water systems will account for an increasing proportion.At present,the non-traditional heat source in the domestic hot water system is the use of solar energy,ground source heat pump,air source heat pump,water source heat pump,etc..The instability and discontinuity of solar energy,influenced by daylight and weather,has been a constraint to its good use.If the project with centralized domestic hot water system is set,the corresponding auxiliary heat source must be set up if the solar heat source is used.The auxiliary heat source is the most important barrier to ensure the stability of the system.However,in terms of economy,solar energy is unmatched by other non-traditional energy sources.With the further improvement of energy saving requirements,the combination of concentrated non-traditional energy and traditional energy is bound to be a mainstream energy utilization of concentrated domestic hot water system in northern China for a period of time.Only by making good use of the combination of non-traditional energy and traditional energy and making the system highly coupled,can the maximum energy saving,stability,safety and reliability of the system be truly achieved.
