摘　　要：为了研究燃气壁挂炉和空调联合供暖的可行性,利用燃气壁挂炉的排烟余热来抑制空调结霜,提高空调的制热系数和使用时间。本文设计了一套余热回收系统,通过空调结霜特性的分析,表明该联合供暖模式具有较好的节能效果和经济效益。利用全国18个城市的气象参数,对该模式进行验证,综合考虑结霜改善情况和节能提高效果,可将18个城市分为鼓励采用、宜采用和可采用三种。其中重庆、长沙、武汉、南京、西安、杭州、福州、上海、石家庄、北京、济南和郑州11个城市属于应当鼓励采用该联合供暖模式的地区。In order to study the feasibility of gas wall-mounted furnace and air-conditioning combined heating,the waste heat of exhaust gas from gas wall-mounted furnace is used to restrain the frosting of air-conditioning and improve theheating coefficient and service time of air-conditioning.This paper designs a set of waste heat recovery system.Through the analysis of Frosting Characteristics of air conditioning,it shows that the combined heating mode has better energy-saving effect and economic benefits.The model was validated by using meteorological parameters of 18 cities in China.Considering the improvement of frost and energy saving,18 cities can be divided into three types:encouragement,suitable and usable.Among them,11 cities in Chongqing,Changsha,Wuhan,Nanjing,Xi’an,Hangzhou,Fuzhou,Shanghai,Shijiazhuang,Beijing,Jinan and Zhengzhou belong to the areas where the combined heating mode should be encouraged.
