摘要:
根据兰州地区的气候特点,提出太阳能喷射与间接蒸发耦合制冷系统.以R134a为制冷剂,基于TRNSYS软件,模拟分析耦合系统为节能建筑供冷时,系统的运行状况及建筑的舒适度情况.对比分析直接蒸发和间接蒸发冷却系统分别与喷射制冷系统耦合的适宜性.结果表明:在兰州地区,间接蒸发冷却与喷射制冷系统耦合更适宜,室内空气舒适度高,间接蒸发冷却子系统可为房间提供55%的冷量,耦合系统综合性能系数(COPm)最大可达13.69;在满足建筑冷负荷需求的前提下,耦合系统典型日内耗电总量5.98 kW·h,占完全用机械压缩制冷系统供冷时耗电量的18.8%,显示出很好的节能效果.
Abstract:
According to the climate characteristics in Lanzhou region, a solar ejector-indirect evaporation coupled cooling system is proposed. Taking R134a as refrigerant, the operation situation and performance of the coupled system and the comfort degree of the room are simulated and analyzed when the coupled system is used to supply cooling for the energy saving building based on TRNSYS software. The suitability of the coupling of direct evaporation and indirect evaporation cooling system to the ejector refrigeration system is compared and analyzed. The result shows that the coupled of indirect evaporation cooling and ejector cooling system is more suitable in Lanzhou region. The comfort of the indoor air is higher with the indirect evaporation cooling system and it can provide 55% of the room cooling capacity.Thesystem comprehensive mechanical coefficient of performance(COPm)is up to 13.69. Under the condition of satisfying the building cooling load demand, the total daily power consumption of the coupled system is 5.98 kW·h, which is 18.8% of the total consumption of the mechanical compression refrigeration system, which shows a good energy saving effect.
