摘要在经济快速增长和人口爆发式的增长过程中,我们对能源的需要也越来越大,这是许多国家都面临的问题。当然我国也不例外,我国也面临着环境和生态的各种问题。最近几年以来我们大力发展城镇话,在城镇华迅速发展的的同时,建筑节能也要随之一起发展。而公共建筑作为其中的耗能大户,其暖通空调系统的节能有很大的潜力,对实现节能减排有着重要而深远的意义。
本设计所选题目为科技书城C区中央空调系统末端设计。本建筑共8层,建筑面积6500m2。首层净高为5米,二层为4.95米,其他楼层净高为4米。要求采用空调夏季制冷冬季供暖,且能够对各个房间进行独立控制,综合考虑各方面的因素,确定此设计的冷热源采用直燃型吸收式冷温水机组,空调系统末端采用风机盘管加新风系统。风机盘管加新风系统有以下优点:1、它比直流系统更节约能源;2、可以对温度进行局部控制;3、可节能整栋大楼空调系统的电气安装容量;4、由于布置灵活,所以适用场合比较多;5、所需机房面积较小;6、使用季节比较长;7、各房间的之间空气不流通,相对来说污染较少。
本设计对各个房间的冷热负荷、湿负荷、新风负荷做了详细的计算,先通过鸿业负荷计算软件进行计算,然后再进行手算校核。为后面的设备选型以及水力计算做了充分的准备。除了进行负荷计算之外也对风系统进行了设计与计算;室内送风方式与气流组织形式的计算选定;水系统的设计、布置与水力计算等内容。20333
Design General Information
With the rapid development of economy and population growth makes the energy demand is increasing, this is many countries are faced with the problem of. China's energy development and ecological environment is also facing a grim situation and challenges. In recent years, China's increasingefforts in city construction, city construction rapid development at the same time, the importance of building energy efficiency is becoming more and more prominent. As the public buildings in large power consumption, energy efficiency of HVAC systems have great potential, has important and far-reaching significance to the implementation of energy-saving emission reduction.
The selected topic is designed to end the Central Technology Bookstore C zone air conditioning system design. The design of central air-conditioning terminal system reasonable for them, to provide a comfortable working environment for the indoor staff. The 8 storey building, construction area of 6500m2. The first floor clear height of 5 meters, the two layer of 4.95 meters, the other floors clear height of 4 meters. Require the use of air conditioning refrigeration in summer and heating in winter, and capable of independent control of each room, comprehensive consideration of various factors, determine the design of cold and heat source with direct fired absorption chiller, air conditioning system at the end of a fan coil unit plus fresh air system. Fan coil plus fresh air system has the following advantages: 1, compared with the dc system, save energy; 2, compared with the centralized air conditioning system for the temperature control of the local area; 3, part to save the building air conditioning system of electrical installation capacity; 4 because of the fan coil is small in size, compact structure, decorate relatively flexible, therefore, for some space is limited or more common frame building has good practicability of the class; 5, the machine room area is lesser, 6, use season longer; 7, each room between air circulation, relatively less pollution.
The contents of this design include: the type for the selected appropriate air conditioning system and determine the design scheme, calculation section is also very important, such as: cooling load calculation; design and calculation of the wind system; selected calculation of indoor air and airflow organization form; design, water system layout and hydraulic calculation etc.. In addition, also need air terminal handling equipment selection and equipment and auxiliary equipment. According to the structural characteristics and exhibition center air conditioning system in the air conditioning unit and terminal equipment selection of appropriate, reasonable arrangement of wind pipe and water pipe position ceiling. 科技书城C区中央空调系统末端设计:http://www.751com.cn/gongcheng/lunwen_12073.html
