地暖+新风系统房间的室内舒适性研究

Study on Indoor Comfort of Rooms with Floor Heating and Fresh Air System

对地暖+新风系统房间室内舒适性进行研究,新风系统设置在建筑面积为141m2,层高为3m,房间人数为3人的房间,卫生间安放新风系统的热交换主机,卧室、客厅等洁净区域设置送风口,卫生间和厨房设置排风口。通过物理模型、数学模型、边界条件和求解器的设置4个步骤建立通风模型。通过CFD模拟结果,综合分析室内温度、速度分布,对室内的PVM和PPD值进行比较。结果表明,地暖+新风系统房间室内舒适性良好,可满足人体对舒适性的需求。

The indoor comfort of rooms with the floor heating and fresh air system was studied. The area of the room is 141 m 2, the height of the room is 3 m, and there are three people in the room. For the fresh air system, the heat exchange host is placed in the toilet, four outlets are respectively in clean areas such as bedrooms, living room and so on. The exhaust outlets were set in the kitchen and bathroom. Through the simplification of the physical model, the mathematical model, the boundary condition and setting of the solver, the ventilation model was established. By CFD simulation results, the indoor temperature and velocity distribution, as well as indoor PVM and PPD were comprehensively analyzed. The simulation results show that the floor heating room with fresh air system indoor comfort is good, and the human demand for comfort also can be met.
