| 摘 要： | 选用大金的1P挂壁机FTXD25DV2C,对蒸气压缩式制冷循环(VCRC)和太阳能喷射式制冷循环(SERC)进行了能耗比较.能耗从火用和一次能源能效比(PEER)方面分析,SERC的(火用)效率为0.065,VCRC的火用效率可以达到0.392 1.SERC在集热器和喷射器中能源的利用率不高,(火用)损失最大.VCRC的一次能源能效比为2.60,而与此相比SERC的一次能源能效比为5.26.但是即使SERC的使用寿命是VCRC的3倍,SERC的初投资的年度化成本依然比VCRC高出三分之一.

| Abstract: | On the base of Daikin air-conditioner(FTXD25DV2C),comparison has been carried out between vapor compression refrigeration cycle(VCRC) and ejector refrigeration cycle driven by solar energy(SERC).The exergy efficiency of SERC is 0.065,while the exergy efficiency of VCRC is much larger and can reach up to 0.392 1.The main exergy loss is on the solar collector and ejector,and the energy efficiency ratio is very low for these two parts.PEER of VCRC is 2.60,and PEER of SERC is 5.26.If the useful life of SERC is ... |
