空气源热泵-散热器供暖系统用于北京地区某农村住宅的实测分析

Field measurement and analysis on air-source heat pump heating system with radiator for a rural house in Beijing area

实测了北京市某农村住宅空气源热泵-散热器低温供暖系统运行期间各房间空气温度、散热器供回水温度及表面温度、系统供热量、耗电量。结果表明,该系统能满足室内热舒适环境的要求,具有供回水温度低、供回水温差小的特点,测试期内系统的COP约为2.8,与传统的电锅炉-散热器供暖系统相比具有良好的节能优势。

Tests the air temperature in rooms, temperature of the radiator surface, temperature of radiator supply and return water, heat supplied for the rural house and the power consumption of the system in the operation period. The results show that the system can meet the need of indoor thermal comfort. The supply and return water temperature are low, and the temperature difference of supply and return water is small. The COP is about 2.8 in the test period and it has advantage of energy saving potential compared with electric boiler plus radiator heating system.
