最近，我们开发了一个全面的计算机模拟人（CSP）的基础上，计算流体动力学（CFD）技术，集成了计算人体模型和呼吸道模型的室内空气质量评价。在这里，我们专注于应用程序的CSP作为一个空气质量和热舒适传感器在室内环境中，并报告的数值程序的加热，通风和空调（HVAC）控制使用CSP作为目标函数的室内环境优化。我们进行了敏感性分析，在一个简单的模型室与一个常设的CSP。采用CFD-CSP方法对流动、温度、湿度和污染物迁移进行了耦合分析。通过体温调节分析和吸入暴露风险来评价人体热舒适性，吸入暴露风险以呼吸道吸入空气中污染物浓度来表示，并作为HVAC控制的反馈参数进行精确分析。与传统的HVAC控制方法相比，使用房间中的点值作为代表值，集成CSP分析的HVAC控制方法显示出对人体周围局部区域进行精确室内环境质量控制的潜力。
Recently, we developed a comprehensive computer simulated person (CSP) based on computational fluid dynamics (CFD) technique that integrates a computational human body model and respiratory tract model for indoor air quality assessment. Here, we focus on the application of this CSP as an air quality and thermal comfort sensor in an indoor environment, and report the numerical procedure for heating, ventilation, and air conditioning (HVAC) control by using this CSP as the objective function for indoor environmental optimization. We conducted sensitivity analyses in a simple model room with a standing CSP. The analyses of flow, temperature, humidity, and contaminant transfers were coupled with CFD-CSP scheme. Human thermal comfort was evaluated by thermoregulatory analysis and inhalation exposure risk, which was represented by the concentration of contaminants in the inhaled air in the respiratory tract, and was precisely analyzed as a feedback parameter for HVAC control. Compared with the conventional HVAC control method using a point value in a room as the representative value, the HVAC control method integrated with CSP analysis showed potential for precise indoor environmental quality control for local zones around the human body.
