It is noteworthy that energy consumption is very high in hotels in order to provide the comfort requirements of human beings. Especially in summer season, cooling is an important condition for comfort in a hotel. In hotel cooling, seawater is an indispensable heat sink. In this study, the thermodynamic performance of a hotel cooling system with seawater‐source and heat pump used with the aim of cooling a hotel located by sea is investigated. Using hourly data collected from the existing system during the summer of 2016, exergy analysis is performed. As the cooling system is at an industrial‐scale involving copious equipment, it is divided into five different cooling zones. For cooling of a selected hotel room, the heat pump and variable refrigerant flow system in the zone where the room was located is also assessed. The results indicated that the hotel cooling system has the coefficient of performance, exergy efficiency, and improvement potential of 4.37, 66.5% and 77.7% on average, respectively. The zone requiring priority improvement is the fifth cooling zone due to air‐conditioning plants and long pipelines. The equipment with the highest exergy destruction is the seawater heat exchanger. Due to low temperature difference between hotel room and seawater, it is necessary to increase use of these systems and develop them in terms of technology.

土耳其某酒店带海水源和热泵的真实冷却系统的实验热力学评估

值得注意的是，为了满足人类的舒适需求，旅馆中的能量消耗很高。尤其是在夏季，降温是保证酒店舒适度的重要条件。在酒店制冷中，海水是必不可少的散热器。在这项研究中，研究了使用海水源和热泵的酒店制冷系统的热力学性能，该系统旨在为海边的酒店提供制冷。利用2016年夏季从现有系统收集的每小时数据，进行了火用分析。由于冷却系统处于工业规模，涉及大量设备，因此分为五个不同的冷却区域。为了冷却选定的酒店房间，还评估了房间所在区域中的热泵和可变制冷剂流量系统。结果表明，酒店制冷系统的性能系数，火用效率和改进潜力分别平均为4.37、66.5％和77.7％。由于空调厂和长管道，需要优先改善的区域是第五个冷却区域。火用破坏最大的设备是海水热交换器。由于酒店房间和海水之间的温差低，因此有必要增加这些系统的使用并在技术方面进行开发。火用破坏最大的设备是海水热交换器。由于酒店房间和海水之间的温差低，因此有必要增加这些系统的使用并在技术方面进行开发。火用破坏最大的设备是海水热交换器。由于酒店房间和海水之间的温差低，因此有必要增加这些系统的使用并在技术方面进行开发。
