建筑物的暖通空调室内空气参数的设定值基本是根据行业标准设置的,而行业标准数值是根据预测平均值投票模型PMV获得并确定的,而 PMV的影响因素涉及地域习惯、使用者穿着和活动姿态等方面.选取PMV=0 的空气参数作为智能控制系统的初始设置数值,并根据用户使用习惯对环境温湿度设定值进行动态修正.以中央空调全空气系统根据冷(热)负荷变化的智能控制为例,构建中央空调智能控制系统,以实现对建筑物暖通空调系统温湿度的监测和控制.
The set values of indoor air parameters of HVAC buildings are basically set according to the industry standard,and the industry standard values are obtained and determined based on the predictive average voting model PMV.The influencing factors of PMV include regional habits,user clothing,and activity posture.The air parameter PMV=0 was selected as the initial setting value of the intelligent control system,and the setting value of the ambient temperature and humidity was dynamically corrected according to the user's habits.Taking the intelligent control of the whole air system of central air conditioning according to the change of cold(hot)load as an example,the intelligent control system of central air conditioning is constructed to realize the monitoring and control of the temperature and humidity of the building HVAC system.
