本设计为济南某综合大楼空调设计，建筑层数为地下二层、地上二十层，建筑总面积为38800m2，主要功能房间是商场、写字楼和住宅区。其中，商场和写字楼采用空调，而住宅区只有冬季供暖。空调区主要采用一次回风和风机盘管加独立新风系统，特别是风机盘管加独立新风系统的新风处理到室内状态点的等焓点，直接送到室内，不承担室内负荷。

空调区的冷热源是土壤源热泵加冷水机组。土壤源热泵是一种利用地下浅层地热资源的既能供热又能制冷的高效节能空调系统。它具有运行成本低、自动化程度高和绿色环保等优点。本次设计依据有关规范和节能舒适性要求，最终达到改善室内环境的目的。66190

Title  A Comprehensive Building Air Conditioning Design in Jinan              

Abstract

This design is about air conditioning design of a comprehensive building that locates in Jinan. There are two stories underground and twenty stories on.

The total floor area is 38800 m2 and its main function room is mall office building and residential area. Among them, the shopping malls and office buildings use air conditioning, but residential area only need winter heating. 

Air conditioning area mainly adopts a return air and fan coil plus with fresh air system independently. Especially ，the fresh air of fan-profile and fresh air is processed to the point whose heat content is the same to the indoor

and it does not hear the load of room.

The hot and cold source of air conditioning is ground-source heat pump plus water chiller. Ground-source heat pump is a kind of high efficiency and energy saving air conditioning system using simple layer of geothermal resources of underground to heat and cool. It possesses the advantages of low operating costs, highly automated and environment friendly. The design meets relevant specification and the requirements of energy conservation and comfort. Ultimately it achieves the purpose of improving the indoor environment.
