摘要

本文为土耳其恰纳卡莱的一栋办公楼提出并模拟了一套干燥剂空气冷却系统,该系统集成了蒸汽压缩冷却装置和热回收装置,适用于夏季。拟议系统设备所需的电能由固体氧化物燃料电池(SOFC)装置提供,该装置使用人类排泄物作为燃料。此外,SOFC 产生的部分废热还用于再生干燥剂轮。模拟还包括三种不同制冷剂对蒸汽压缩冷却装置的影响。在制冷剂中,使用 R1234ze(Z) 的系统获得了最高的电 COP,比使用 R717 和 R1233zd(E) 的系统分别高出 3.14% 和 2.40%。此外,与其他系统相比,使用 R1234ze(Z) 的系统可节省 9.97% 和 9.23% 的电力。与 R717 和 R1233zd(E)相比,R1234ze(Z)的节电效果可分别节省 1.19% 和 0.90% 的燃料。在夏季,现有 SOFC 设备的发电量满足了干燥剂混合冷却系统总耗电量的 82.00%。此外,在夏季,使用 SOFC 和不使用 SOFC 的干燥剂混合冷却系统的一次能源消耗量相差 3984.56 千瓦时。

Summer period analysis of the rotary desiccant - hybrid cooling system combined with solid oxide fuel cells using human waste fuel
This paper proposes and simulates a desiccant air cooling system integrated with a vapor compression cooling unit and a heat recovery unit for an office building in Çanakkale, Turkey, during the summer season. The required electrical energy for equipment of the proposed system is supplied by an Solid Oxide Fuel Cells (SOFC) unit using human waste as fuel. Moreover, some of the waste heat generated by the SOFC is used to regenerate the desiccant wheel. The simulation also includes the effects of three different refrigerants for the vapor compression cooling unit. Among the refrigerants, the highest electrical COP was obtained for the system using R1234ze(Z), which is 3.14% and 2.40% higher than the systems using R717 and R1233zd(E), respectively. Additionally, the system using R1234ze(Z) achieved electrical savings of 9.97% and 9.23% compared to the other systems. These electrical savings resulted in fuel savings of 1.19% and 0.90% for R1234ze(Z) compared to R717 and R1233zd(E), respectively. During the summer season, the electricity production from the existing SOFC unit met 82.00% of the total electricity consumption of the desiccant hybrid cooling system. Furthermore, a difference of 3984.56 kWh in primary energy consumption was identified between the desiccant hybrid cooling systems operating with the SOFC and without the SOFC during the summer season.
