摘要
提出采用热泵来取代传统的电加热器,构成热泵辅助太阳能中央热水系统,可有效地降低能源消耗。结合2005年西安地区气象数据,建立了合适的数学模型,并用现有的试验数据对模型进行了校准,通过模型模拟了该年热泵辅助和电辅助太阳能中央热水系统的性能系数,输入功耗,出水温度等运行参数,并对两者进行了对比。
A heat pump assisted SCWH was proposed via replacing the electrical heating appliance with the heat pump, so the power consumption can be reduced sharply. However, meanwhile, there is few study around the annual operating characteristics of SCWH, so based on the meteorological data in 2005, Xi＇an city, a proper mathematical model calibrated by some experimental data was setup to simulate the annual performance coefficient, input power, outlet temperature of the heat pump and electricity assisted SCWH respectively. The result showed the heat pump assisted SCWH has higher efficiency than that of the electricity assisted SCWH.
