毕业设计（论文） 题目名称：合肥瑞安宾馆空调系统设计  摘 要 本设计为合肥瑞安宾馆空调系统设计。此次设计的空调系统为舒适性空调系统，主要任务是完成空调系统和冷冻站的设计。根据房间功能和面积不同进行分区，在大空间中，如多功能厅，使用一次回风系统；由于工程一至九层，主要功能区为客房，本设计使用风机盘管加独立新风系统。新风处理到室内焓值，不承担室内冷负荷，风机盘管承担房间全部冷负荷和部分湿负荷；水系统的水平管采用同程式的布置方式，立管采用异程式布置。冷冻站设置冷水机组，作为整个空调系统的冷源；冷冻站还设置了板式换热器，热量由城市热网提供。 在冷负荷计算的基础上完成末端设备的选型，并通过风量、水量的计算确定风管路和水管路的尺寸规格，并校核最不利环路的阻力和压头用以确定新风机和水泵。 本文主要以一层，标准层和顶层空调系统为例，予以详细说明，以节能为前提，依据相关的空调设计手册所提供的参数，进一步完成末端设备、水泵、制冷机组等的选型，从而将其反应在图纸上，最终完成整个空调系统设计。 关键词：中央空调，一次回风，风机盘管，独立新风，节能 The Design of Air Conditioning System for RuiAn Guesthouse Abstract The graduation project design is Air Conditioning System of RuiAn Guesthouse ,which is a comfort air-conditioning system. The main task of the project is to complete the design of the indoor air-conditioning system、and the design of refrigeration station.In the big hall ,uses primary return air system.Due to Guesthouse is the main function, the design adopts fan-coil units plus fresh air system in small space.Fresh air is handled to indoor enthalpy value,and not bear indoor cold load.Fan-coil system bear the whole indoor load and part moisture load; Aqueous systems horizontal pipe selects reversed return system and direct return system, riser pipe adopts direct return system. The refrigeranting station establishment the cold water group, takes the entire air-conditioning systems heat sink; The refrigeranting station also establishes the plate heat exchanger. Based on the calculation ofend equipment is completed, and through the calculation of wind, water, the wind pipe and the water pipeline specifications are determined, and checking the resistance and pressure of the most unfavorable loop to determine head new fans and pumps. This article mainly take three with the key bed air-conditioning system as an example, gives the detailed explanation, take the energy conservation as a premise, the selection of end equipment is further completed, which will be reflected in the drawings, so the air conditioning system is
