地板个性化送风能够改善工作区微环境的空气品质和热舒适性，其送风温度较传统空调系统高，有较大的节能潜力。对送风采用冷冻除湿和转轮除湿时，节能与否或者节能程度大小分别取决于再热量和再生热量及再生风机能耗。本文中，利用能耗模拟分析软件Energyplus分别模拟计算了在中国各气候区使用混合通风、冷冻除湿的地板个性化送风及转轮除湿的地板个性化送风系统时，各系统的年能耗，并进行了比较分析，得出地板个性化送风系统在中国各气候区的能耗特性。
地闆箇性化送風能夠改善工作區微環境的空氣品質和熱舒適性，其送風溫度較傳統空調繫統高，有較大的節能潛力。對送風採用冷凍除濕和轉輪除濕時，節能與否或者節能程度大小分彆取決于再熱量和再生熱量及再生風機能耗。本文中，利用能耗模擬分析軟件Energyplus分彆模擬計算瞭在中國各氣候區使用混閤通風、冷凍除濕的地闆箇性化送風及轉輪除濕的地闆箇性化送風繫統時，各繫統的年能耗，併進行瞭比較分析，得齣地闆箇性化送風繫統在中國各氣候區的能耗特性。

Under floor personalized ventilation system can improve the inhaled air quality and thermal comfort. It has a large energy-saving potential with the higher supply air temperature compared with the traditional air conditioning systems. For the refrigeration dehumidification, the key element determining the energy consumption of the system lies on the energy to reheat the supply air, while for the rotary-wheel dehumidification it lies on the regenerator and the regeneration fan. In this study, the energy consumption of traditional mixing ventilation system, under floor personalized ventilation systems combined with the above methods of dehumidification has been simulated and compared in different climates with Energyplus, obtaining the energy consumption features of different systems in different climates.
