本研究对装有细水雾发生装置的空调系统进行了成本效益分析。利用系统模拟和计算流体力学相结合的方法，研究了空调节能效益与水成本的关系。k-？湍流模型、物种传输方程和离散相模型同时求解，以捕捉CFD中的传热传质效应。通过改变喷雾水滴直径、环境干球温度、环境相对湿度、喷雾水量、水温和喷雾系统的位置来进行参数研究。在计算了喷水引起的空气温降和湿度比增加后，进行了系统模拟，以估计每种情况下的功耗降低和容量增加。 本研究推断，为了节省空调设备运行的总成本，应仔细选择运行条件。引用:2020年虚拟会议论文

In this study, a cost effectiveness analysis is conducted for an air-conditioning system equipped with a water mist generating device. System simulationscoupled with computational fluid dynamics are utilized to study air conditioner power-saving benefits versus water cost. A k-? turbulence model, speciestransport equations, and a discrete phase model are solved simultaneously to capture heat and mass transfer effects in CFD. A parametric study iscarried out by varying the spray water droplet diameter, the ambient dry bulb temperature, the ambient relative humidity, the spraying water amount, thewater temperature, and the spray system’s location. After calculating air temperature drop and humidity ratio increase by the water spray, asystem simulation is conducted to estimate the power consumption reduction and the capacity enhancement for each condition. This study deduces theoperating condition should be carefully selected to save the total cost of air-conditioning equipment operation.
