| 摘 要： | 通过对传统下置置换通风系统特点的研究,提出了一种新的下置置换通风空调系统——由太阳能烟囱为新系统中送风提供热压动力,使送风具有传统下置置换通风系统的送风特点,室内工作区具有良好的空气品质。同时通过数值模拟的方法分析并比较了传统下置置换通风系统与新系统。结果表明:该系统能解决传统置换通风不舒适的吹风感和竖直温差大的问题;相对于传统下置置换通风,新系统还具备节能和环保特性;烟囱具有良好的自我调节性能。

| Abstract: | Through studying on the characteristic of the traditional down-fixing diffusers displacement ventilation,a new HVAC system is brought forward,which combines solar energy chimney with down-fixing diffusers displacement ventilation.At the same time,the new system and the traditional down-fixing diffusers displacement ventilation are analyzed and compared according to the method of numerical simulations.The result shows that traditional down-fixing diffusers displacement ventilation systems may make people feel uncomfortable by wind and cause greater vertical temperature differences,while the new system can solve those problems.Comparing with traditional down-fixing diffusers displacement ventilation systems,the new system has the characteristic of energy saving and environmental protection.Chimney is provided with a well self-adjustability. |
