摘要
介绍了在夏热冬冷地区以太阳能集热器和空气源热泵系统为热源、以地暖设备为换热末端的供暖系统,对其进行的一系列理论和实验研究结果表明:①该系统房间符合ISO7730标准规定的PMV(人体热感评价指标)-PPD(预期不满意率)指标,房间内热舒适性良好。②冬季工况下该供暖方案在热舒适性和节能性上都具有一定优势,约为单一热泵供暖能耗的66%。③春季工况下单一热泵地暖循环中,预定的加热温度越低就越经济节能,而变流量工况并没有明显的效果差异。④将热泵与太阳能集热器联合运行,可以使机组快速升温,同时运行费用仅为单一热泵供暖的60%~70%。
This paper introduces a series of theoretical and experimental research results of solar collectors and air source heat pump systems as heat sources and floor heating equipment as heat exchange ends in summer hot and cold winter areas,including:①The system room meets the PMV(Human Thermal Sensing Index)-PPD(Expected Unsatisfactory Rate)indicator specified in the ISO7730 standard,and the room has good thermal comfort.②Under the winter conditions,the heating scheme has certain advantages in thermal comfort and energy saving,which is about 66%of the energy consumption of a single heat pump.③The lower the predetermined heating temperature,the more economical and energy-saving the system.The variable flow conditions have no obvious difference in effect.④The combined operation of the heat pump and the solar collector allows the unit to heat up quickly,while operating at a cost of only 60%~70%of a single heat pump.
