通过对辐射冷顶板与置换通风复合空调系统以及辐射冷顶板与贴附射流复合空调系统的评价分析,提出将三者结合起来的新型空调系统。建立贴附射流作用下辐射冷顶板与置换通风复合空调系统房间的模型,利用Fluent软件对该房间进行模拟。通过模拟分析,得出房间的温度分布情况以及气流分布情况。模拟结果表明:贴附射流作用下辐射冷顶板加置换通风空调系统在保证房间良好舒适性的同时,可以有效减轻顶板结露问题,使辐射冷顶板在理想的工作温度下运行,提高了辐射冷顶板的供冷能力,保证了房间良好的热环境。
Through the evaluation and analysis of radiant cold roof and displacement ventilation composite air conditioning system and radiating cold roof and attached jet composite air conditioning system, a new air conditioning system combining the three is proposed. The model of radiating cold roof and replacing ventilation and ventilation air-conditioned room with jets attached to the jet was built and the room was simulated by Fluent software. Through the simulation analysis, the temperature distribution of the room and the distribution of the airflow are obtained. The simulation results show that the radiating roof and replacement ventilation and air-conditioning system can effectively reduce the dew condensation of the roof while ensuring the good comfort of the room, and make the radiating cold roof run at the ideal working temperature and improve the radiating cold Cooling capacity of the roof to ensure that the room a good thermal environment.
