个性化通风（PV）是一种单独控制的空气分配系统，旨在改善吸入空气的质量和每个乘员的热舒适性。许多研究表明，与传统的机械通风系统相比，PV可以改善居住者的健康，吸入空气质量，热舒适性和自我评估的生产力。人们对其能源性能知之甚少。在这项研究中，一个个性化的通风系统，在办公楼位于炎热潮湿的气候（新加坡）的能耗进行了研究，通过模拟与经验测试的IDA-ICE软件。结果表明，光伏发电的使用可以大大降低能源消耗（高达51%）相比，混合通风时，应用以下控制策略：（a）降低气流速度，由于更高的通风效率的PV;（B）增加最大允许室内空气温度，由于PV容量控制小气候;（c）只在占用人在办公桌旁时供应室外空气。控制送风温度的策略不会影响炎热潮湿气候下的能耗。(C)2009 Elsevier B.

Personalized ventilation (PV) is an individually controlled air distribution system aimed at improving the quality of inhaled air and the thermal comfort of each occupant. Numerous studies have shown that PV in comparison with traditional mechanical ventilation systems may improve occupants' health, inhaled air quality, thermal comfort, and self-estimated productivity. Little is known about its energy performance. In this study, the energy consumption of a personalized ventilation system introduced in an office building located in a hot and humid climate (Singapore) has been investigated by means of simulations with the empirically tested IDA-ICE software. The results reveal that the use of PV may reduce the energy consumption substantially (up to 51%) compared to mixing ventilation when the following control strategies are applied: (a) reducing the airflow rate due to the higher ventilation effectiveness of PV; (b) increasing the maximum allowed room air temperature due to PV capacity to control the microclimate; (c) supplying the outdoor air only when the occupant is at the desk. The strategy to control the supply air temperature does not affect the energy consumption in a hot and humid climate. (C) 2009 Elsevier B.V. All rights reserved.
