The purpose of this study is to analyze the human response to the indoor climate with two individually controlled convective and radiant cooling systems: a low velocity unit combined with radiant panel system (LVRP) and a personalized ventilation system combined with a radiant panel system (PVRP). As a reference system without individual control, diffuse ceiling ventilation combined with a radiant panel system (DCV-RP) was also studied. In laboratory conditions, 10 males and 10 females gave subjective response to the indoor climate during various office activities. The indoor parameters and CO₂ concentrations were measured. The results show that with the reference DCV-RP system, the indoor conditions were worse than with the LVRP and PVRP systems. The thermal sensation and perceived air quality with the PVRP system was better than the LVRP system. After a medium activity task, the thermal acceptability reverts faster with the PVRP than LVRP system. Both the LVRP and PVRP systems were able to create a micro-environment around the workstations and the CO₂ concentrations near the workstation were slightly lower than at the exhaust grille. Compared with the PVRP system, the subjects preferred the higher airflow rate at the workstation with the LVRP system. Males preferred a higher airflow rate than females under the same conditions with both micro-environment systems. This research found that there was significant variation in the control preferences of the human subjects concerning the micro-environment, and this emphasizes the need for personalized control to ensure that all occupants are satisfied with the indoor conditions.

这项研究的目的是通过两种独立控制的对流和辐射冷却系统来分析人类对室内气候的响应：低速单元与辐射板系统（LVRP）组合以及个性化通风系统与辐射板系统（PVRP）组合）。作为没有单独控制的参考系统，还研究了扩散顶棚通风与辐射板系统（DCV-RP）的组合。在实验室条件下，在各种办公室活动中，有10位男性和10位女性对室内气候产生了主观反应。室内参数和CO ₂测量浓度。结果表明，使用参考DCV-RP系统时，室内条件比使用LVRP和PVRP系统时差。PVRP系统的热感和感知空气质量优于LVRP系统。完成中等活动任务后，PVRP的热可接受性比LVRP系统恢复更快。LVRP和PVRP系统都能够在工作站和CO ₂周围创建微环境。工作站附近的浓度略低于排气格栅处的浓度。与PVRP系统相比，受试者更喜欢使用LVRP系统的工作站处更高的气流速率。对于两个微环境系统，在相同条件下，雄性均比雌性更喜欢较高的气流速率。这项研究发现，人类对象在微环境方面的控制偏好存在显着差异，这强调了个性化控制的必要性，以确保所有乘员对室内条件都感到满意。
