由于资金和建筑方面的限制，现有的博物馆建筑通常不允许对复杂的HVAC系统进行改造。因此，一个有吸引力的方法来提高博物馆房间的微气候质量是改善已经安装的系统的控制。本文提出了一种新颖的控制策略，以大大减少温度和相对湿度的波动，在一个温和的气候在波兰博物馆的霍尔斯。该方法包括改进现有室内温度和通风气流控制系统的控制，而不需要加湿和加湿装置。使用EnergyPlus软件进行模拟;使用现有测量数据校准和验证建筑物的多区域模型。模拟了一年中的温暖时期，并对其中的六周进行了实验验证。现有的加热和冷却系统包括散热器，在某些地区，风扇盘管。通过改进控制方案和增加室外风机，使相对湿度波动较小（<±5%）的时段由2%增加到88%。
Due to financial and construction limitations, existing museum buildings often do not allow the retrofit of complex HVAC systems. Thus, an attractive way to improve the quality of the microclimates in the museum rooms is to improve the control of systems that are already installed. This paper presents novel proven control strategies to drastically reduce the temperature and relative humidity fluctuations in the exhibitions halls of a Polish museum in a moderate climate. The methods comprise improved control of existing indoor temperature and ventilation airflow control systems, without humidification and dehumidification devices. Simulations were performed with EnergyPlus software; the multi-zone model of the building was calibrated and verified with existing measured data. A warm period of the year was simulated, and six weeks of it were experimentally validated. The existing heating and cooling systems comprised radiators and in some areas, fan-coils. Through improved control schemes and the addition of outdoor air fans, the period with the small relative humidity fluctuations (<±5%) increased from 2% to 88% in the season.
