保定市农村住宅空气源热泵供暖调研及分析

Investigation and Analysis of Air Source Heat Pump Heating for Rural Residential Buildings in Baoding City

为了解寒冷地区农村“煤改电”项目实施成效,选取河北省保定市农村煤改电用户开展实地调研,分析了农村地区居民热水型空气源热泵的使用行为特征及供暖需求。结果表明:保定地区60%以上的农户供暖季空气源热泵热水机组的使用模式为全天开启,且农户在使用期间不对空气源热泵热水机组出水温度以及房间供暖末端进行调控的占多数;空气源热泵热水机组供暖条件下,农村住宅供暖区域一般为客厅和卧室,供暖室内温度主要集中在16~18℃;农户满意度调查结果显示,热水型空气源热泵总体上可以满足农户基本的供暖需求,供暖系统运行费用偏高与供暖房间热舒适性欠佳是目前热水型空气源热泵在保定农村地区实际应用中存在的主要问题。

In order to understand the implementation effectiveness of the"coal to electricity"project in rural areas of cold regions,a field survey was conducted among rural coal to electricity users in Baoding City,Hebei Province.The usage behavior characteristics of air source heat pump hot water units among rural residents and their heating needs were analyzed.The results show that over 60%of rural households in Baoding area use air source heat pump hot water units all day during the heating season,and the majority of users do not regulate the supply water temperature of the air source heat pump hot water units or the heating terminals of the room during use;Under the heating conditions of air source heat pump hot water units,the heating areas of rural residential buildings are generally the living room and bedroom,and the indoor temperature is mainly concentrated in 16-18℃;The satisfaction survey results of rural residents show that the air source heat pump hot water unit can generally meet the basic heating needs of rural residents.The high operating cost of the heating system and the poor thermal comfort of the heating room are the main problems in the practical application of the air source heat pump hot water unit in rural areas of Baoding.
