上海地区空气源热泵散热器供暖系统应用研究

Application study on radiator heating system with air-source heat pump in Shanghai area

以上海地区某办公建筑空气源热泵散热器供暖系统为研究对象,实测了室内空气温度、围护结构内表面温度、机组供回水温度和热泵电耗,计算了系统和机组的制热性能系数,并结合室内人员的热感觉评价对该供暖系统的舒适性作了分析。结果表明,在测试条件下,该供暖系统的COP约为1.81,室内平均温度为21℃;与常规供暖系统相比,空气源热泵散热器供暖方式的系统制热COP偏低,但室内温度较稳定,竖直温差较小;该供暖方式应用在大空间办公室时,由于温升速率较慢,宜采用连续供热的运行方式。

Taking the air-source heat pump（ASHP） heating system with radiators of a public building in Shanghai as the research object, tests the indoor air temperature, the temperature of envelope surface, supply and return water temperature of the space heating system, and heat pump energy consumption. Calculates the heating coefficient of performance of the sy,;tem and the ASHP unit, and analyses thermal comfort of the heating system with thermal comfort evaluation of indoor personnel. The results show that under the experimental conditions, the COP of the heating system is about 1.81, and the average indoor temperature is 21 ~C; compared with the conventional heating system, the COP of the ASHP heating system with radiators is lower, but the indoor temperature： is more stable, and the vertical temperature difference is smaller; as the rate of temperature rise is slow, the operation mode of continuous heating should be taken if the heating system with radiators is used in the offices with larze soace.
