摘　　要：采暖问题始终是社会关注的热点问题,能源使用效率低是制约采暖的主要因素之一。空气源热泵是一种高效清洁能源,其缺点为运行能效受冬季室外低温影响产生结霜现象,进而影响机组运行。通过TRNSYS模拟软件对空气源热泵与电磁能耦合的供热系统进行模拟研究,系统形式为空气源热泵与电磁加热器并联,耦合供热系统的采暖季平均COP为2.1,供暖水温达到45℃以上。结果表明,耦合供热系统的运行效果优于单一能源。此耦合供热系统供热效果良好,并为解决空气源热泵在严寒冬季停止运行的问题提供技术参考。Energy is the cornerstone of social development.In recent years,people’s demand for energy is gradually increasing.Heating has always been a hot issue of social focus.Low energy efficiency is one of the main factors restricting heating.Air source heat pump is a kind of high efficiency energy and it is a clean and pollution-free energy.Its disadvantage is that the operation energy efficiency is affected by the outdoor low temperature in winter,resulting in frosting phenomenon,which affects the operation of the unit.The heating system of air source heat pump coupling electromagnetic energy is simulated by TRNSYS software.The average COP of the coupled heating system is 2.1 in heating season,and the heating water temperature is above 45℃.The results show that the operation effect of coupled heating system is better than that of single energy.The coupled heating system has fine effect in the field of heating and provides technical reference for solving the problem of air source heat pump stopping operation in severe cold winter.
