摘　　要：提出一种太阳能喷射-压缩复合蓄冷新系统,设计并搭建系统性能实验研究平台,以R134a为制冷剂,实验分析得出太阳能喷射-压缩复合蓄冷系统的最优运行工况。结果表明:系统能效比整体随蒸发温度的升高而升高;在不同的蒸发温度阶层内,系统能效比均呈先增加后降低的变化规律,系统功耗均呈先降低后上升的变化规律;在冷凝温度为32℃及中间温度为15℃时,存在最优的发生温度,最优发生温度介于76~78℃之间,此时能效比最高,可达2.65;总功耗最低,可达330 W。同样,系统在研究工况范围内存在最优的中间温度,当冷凝温度为35℃时,最优中间温度介于12~16℃之间,此时系统能效比最高,最高能效比可达2.6,总功耗呈不断减少的趋势,系统的总功耗最低为300 W。A new system of solar energy injection-compression composite storage is proposed. The system performance experiment platform is designed and built. R134 a is used as refrigerant to study the system performance of solar energy injection-compression composite storage system. The results show that the EER increases with the increase of the evaporation temperature;In different evaporation temperature classes,the EER with the increase of the generator temperature showed a trend of first increase and then decrease,the total energy consumption with the increase of the generator temperature showed a trend of first decrease and then increase. When the condensation temperature is 32 ℃ and the intermediate temperature is 15 ℃,there is an optimal temperature. The optimum temperature is between 76 ℃ and 78 ℃. The energy efficiency ratio is 2.65,the lowest power consumption is 330 W. Also within the scope of the study conditions,the system has the optimal intermediate temperature,the optimal intermediate temperature is between 12 ℃ and 16 ℃ when the condensing temperature is 35 ℃. At this time,the system energy efficiency ratio of the highest,the maximum energy efficiency ratio of 2.6,the total power consumption continues to decline trend,the system’s total power consumption of the minimum 300 W.
