摘要
将酒店房间空调2种送新风方式的空气处理方案进行对比,并运用CFD软件对室内空调热环境进行数值模拟。与新风接回风箱式送风相比,新风直送式的PMV、PPD值满意面积大27.2%、29.3%。此外,新风直送式系统更便于控制和管理且室内空气新鲜度容易得到保证,而新风接回风箱式数值模拟存在30%室内面积的气流死角。对酒店房间空调而言,新风直送式更值得选用。
The air handling processes of two fresh air supply models used for hotel room were compared and the thermal envi- ronment of indoor was simulated by the CFD software. Compared with the model that the fresh air was sent into the room after mix- ing with return air ,the model without mixing lead to a 27.2% and 29.3% larger indoor area acquired a reasonable PMV and PPD value, respectively. Besides, the system of no mixing model can be controlled and managed conveniently and the quality of indoor air can be guaranteed easily, but the mixing model has a 30% room area which the air can＇ t pass through. The model without mix- ing is more suitable for a hotel room.
