| 摘 要： | 太阳能喷射式制冷(热泵)系统在满足供冷、供热需求时，通常需要补充一定量的一次常规能源。该文在系统能量平衡的基础上，引入太阳能倍率、冬夏负荷比等参数，推导了太阳能制冷系统与电压缩制冷系统的一次能耗比计算公式。进而对太阳能双元混合工质喷射式制冷(热泵)系统、单元工质喷射式制冷系统、太阳能直接供热系统与电压缩制冷系统的一次能源消耗进行了对比分析。结果表明，太阳能喷射式热泵比太阳能直接供暖系统节约一次常规能源；太阳能喷射式制冷(热泵)系统，在其太阳能倍率位于节能区时，比电压缩制冷(热泵)系统节约一次常规能源。

| Abstract: | Equations of primary traditional energy demand ratio between SERS (solar ejector refrigeration system) or direct heating system (DHS) and a compression chiller which can work as a heat pump during wintertime were derived by introducing parameters such as solar fraction and the ratio between heating and cooling load on the basis of energy equilibrium. The primary traditional energy consumption of SERS or DHS was compared with a compression chiller. The result showed that SERS can save more primary traditional energy than DHS or a compression chiller during its energy efficiency area. |
