【摘要】：為進一步提高能源利用率和提升低品位余熱的品質(zhì),實現(xiàn)能量梯級利用,針對燃氣機熱泵系統(tǒng)開展了制冷性能實驗及余熱驅(qū)動的有機朗肯循環(huán)理論仿真研究。結(jié)果表明:燃氣機熱泵系統(tǒng)制冷量、發(fā)動機余熱以及發(fā)動機一次能耗均隨燃氣發(fā)動機轉(zhuǎn)速升高而增大;性能系數(shù)(COP)及一次能源利用率(PER)隨蒸發(fā)器進水溫度的升高而增大,但隨發(fā)動機轉(zhuǎn)速升高而降低。COP和PER分別高于6.0和1.1。在蒸發(fā)溫度60~86℃范圍內(nèi),以R245fa作為有機工質(zhì)的有機朗肯循環(huán)熱力學第一定律熱力效率為7.39%~10.95%,熱力學第二定律?效率為42.65%~52.25%。
[Abstract]:In order to further improve energy utilization and improve the quality of low-grade waste heat, energy cascade utilization can be realized. The refrigeration performance of gas engine heat pump system and the simulation study of organic Rankine cycle driven by waste heat are carried out. The results show that the refrigerating capacity of gas engine heat pump system is high. The residual heat of the engine and the primary energy consumption of the engine increase with the increase of the speed of the gas engine. The coefficient of performance (COP) and the primary energy utilization ratio (per) increased with the increase of the inlet temperature of the evaporator. However, with the increase of engine speed, the. Cop and PER are lower than 6. 0 and 1. 1 respectively. The evaporation temperature is 60 ~ 86 鈩，
