Many building are characterized by insufficient air exchange, which may result in the symptoms of sick building syndrome (SBS). A large number of existing buildings are equipped with natural ventilation, whose work is disturbed by activities going to energy-saving. The thermomodernization activities are about mounting new sealed windows and laying thermal isolation, which reduces the amount of infiltrating/exfiltrating air. In many cases, the mechanical ventilation cannot be used due to a lack of a place in building or architectural and construction requirements. One of the solutions to improve the indoor microclimate is the decentralized façade ventilation. In the article, the internal air parameters in an office room equipped with decentralized façade ventilation device were analyzed. The room was equipped with a decentralized façade unit, which cyclically supplied and removed air from the room. The time of the supply/exhaust was changed to 2 min, 4 min, and 10 min. The temperature and the humidity of the indoor air and the outdoor air and the concentration of carbon dioxide inside the room were measured. The analysis showed that despite the lack of a heater in the device, the air temperature in the workplace and in the central point of the room was in the range of 20–22 °C. The air humidity was in the range of 27–43%.

配有分散式立面通风设备的房间内的小气候

许多建筑物的特点是空气交换不足，这可能会导致建筑物综合症（SBS）的症状。现有的许多建筑物都配备了自然通风，其工作受到节能活动的干扰。热现代化活动是关于安装新的密封窗并铺设隔热层，从而减少了渗透空气的量。在许多情况下，由于在建筑物或建筑和施工要求中缺少位置，因此无法使用机械通风。改善室内微气候的解决方案之一是分散式立面通风。在这篇文章中，分析了装有分散式立面通风设备的办公室室内的内部空气参数。房间里装有分散的立面单元，周期性地从室内供气和排除空气。供气/排气时间分别更改为2分钟，4分钟和10分钟。测量室内和室外空气的温度和湿度以及室内的二氧化碳浓度。分析表明，尽管设备中没有加热器，但工作场所和房间中心点的空气温度仍在20-22°C之间。空气湿度在27-43％的范围内。工作场所和房间中央的气温在20-22°C之间。空气湿度在27-43％的范围内。工作场所和房间中央的气温在20-22°C之间。空气湿度在27％到43％之间。
