哈尔滨石油学院毕业设计（论文） 地区酒店中央空调设计 系部名称： 专业班级： 学生姓名： 指导教师： 职 称： 哈尔滨石油学院 二Ｏ年月摘　要 酒店的中央空调系统设计。该酒店共六层，建筑总面积3360，主要包括：商场、客房、休息大厅等。空调区面积取其90%左右，该系统的夏季冷负荷为810。夏季设计的室内空气温度为25℃，相对湿度为50﹪。考虑到杭州所处的地理位置和气象参数、经济性以及可行性，得出了一套空调系统方案，并针对此方案进行了水力计算、设备选型。对于空调系统中的管道保温、消声、减震、防火、排烟也做了一定的设计。 在计算负荷时采用冷负荷系数法，全面考虑了各种重要的冷负荷，为性价比最高的设备选择打下良好的基础。在风道设计计算中通过比较合理的布置风道管线，从而准确地确定了经济的风道尺寸，以及合理的散流器布置，整个系统采用分区的设计方法，通过水系统的计算，选择不同类型的冷水机组，新风机组，冷冻水泵等设备。 本设计中整个酒店设计中央空调，即所有宾馆的决大部分面积进行空气处理。该系统采用螺杆式冷水机组制冷。 关键词：中央空调系统；冷负荷；冷负荷系数法；冷水机组 Abstract Designs a set of central air-conditioning for a hotel of hangzhou . This hotel altogether five, the construction total area is 3360㎡, mainly including: stores, guest room, and rest, hall, etc. Air conditioning area take its 90% or so, the system of summer cold load for 810. The summer of indoor air temperature for design 25℃, relative humidity of 50﹪. Considering the hangzhou in geographic location and meteorological data, economy and feasibility, and draw the conclusion that a set of air conditioning schemes, and in the light of the scheme in the hydraulic calculation, selection of equipment. Air conditioning system for the pipe insulation, sound attenuation, shock absorption, fire prevention, smoke also did some design. In calculating load by cold load coefficient method, the comprehensive consideration of the various kinds of important cooling load, for the highest cost-effective equipment selection lay a good foundation. In duct design calculation by comparing and reasonable decorate duct pipeline, which accurately determine the size of the economy ducts, and scattered the flow of reasonable arrangement, the whole system using zoning design methods, through the calculation of the water system, the choice of different types of water chiller, air units, and the frozen water pumps and other equipment. This design is the hotel design central air conditioning, that all of the hotels most of air processing area. The system adopts the screw water chillers refrigeration. K
