| 摘 要： | 为了研究太阳能水源热泵系统供热工况下的运行特性,引入了可再生能源建筑应用工程评价标准中相关方法.通过对长沙地区冬季工况模拟研究和分析,得到太阳能集热系统和水源热泵系统在不同工况下的制热效率.研究结果表明,在引入太阳能后避免了水源热泵机组冬季长时间运行使制热性能下降并频繁进入保护工况,且当蒸发器进口水温为22℃附近时,机组COP较10℃提高了9.13%,达到最优值.

| Abstract: | In order to study the combined operating characteristics of solar water-source heat pump under heating conditions, renewable energy construction project evaluation criteria method was in- troduced. The heating efficiency of the solar collector system and water source heat pump system in different conditions are obtained according to the simulation studies and analysis of Changsha in winter conditions. The results show that introduction of solar energy can avoid the emergence of water source heat pump units winter long-running decline in the performance of the heating and frequently into the phenomenon of protective conditions. When the evaporator inlet water tempera- ture is around 22 ℃, the unit COP increase by 9.13 % than the evaporator inlet water temperature is 10 ℃ and it reach an optimal value. |
