无线传感器网络（WSN）技术已成功应用于许多地方的节能应用，在实现节能方面发挥了重要作用。然而，以前的研究没有讨论无线传感器网络的成本和成本回收。无线传感器网络的应用目前仅限于研究和实验室实验，而不是大规模工业生产，主要是因为企业主不熟悉无线传感器网络投资可能带来的良好回报和成本回收。因此，本文重点研究了无线传感器网络的成本回收以及如何降低便利店的空调能耗。在这项研究中使用的无线传感器网络提供反馈到网关，并采用预测平均投票（PMV）和计算流体动力学（CFD）的方法，让客户在一个舒适而节能的环境中购物。自2008年以来，台北的四家便利店已经使用了拟议的WSN。2008年，该实验最初旨在优化空调以实现节能，但2008年之后继续增加设置，在2009年增加了热舒适性和人群高峰，非高峰功能，以实现人性化的节能。与2007年的数据相比，在相同的舒适度条件下，显示节能分别增加了40%（2008年）和53%（2009年）。无线传感器网络设备的成本为500美元。实验结果，包括三年的分析和计算，表明四家便利店的边际节能效益达到节能高达53%，在大约5个月内收回所有成本。参与本研究的便利店集团对节能效率感到满意，因为成本回收期短。
Wireless sensor network (WSN) technology has been successfully applied to energy saving applications in many places, and plays a significant role in achieving power conservation. However, previous studies do not discuss WSN costs and cost-recovery. The application of WSNs is currently limited to research and laboratory experiments, and not mass industrial production, largely because business owners are unfamiliar with the possible favorable return and cost-recovery on WSN investments. Therefore, this paper focuses on the cost-recovery of WSNs and how to reduce air conditioning energy consumption in convenience stores. The WSN used in this study provides feedback to the gateway and adopts the predicted mean vote (PMV) and computational fluid dynamics (CFD) methods to allow customers to shop in a comfortable yet energy-saving environment. Four convenience stores in Taipei have used the proposed WSN since 2008. In 2008, the experiment was initially designed to optimize air-conditioning for energy saving, but additions to the set-up continued beyond 2008, adding the thermal comfort and crowds peak, off-peak features in 2009 to achieve human-friendly energy savings. Comparison with 2007 data, under the same comfort conditions, shows that the power savings increased by 40% (2008) and 53% (2009), respectively. The cost of the WSN equipment was 500 US dollars. Experimental results, including three years of analysis and calculations, show that the marginal energy conservation benefit of the four convenience stores achieved energy savings of up to 53%, recovering all costs in approximately 5 months. The convenience store group participating in this study was satisfied with the efficiency of energy conservation because of the short cost-recovery period.
