以重庆主城某大型商业区的空调系统设计为例，从冷热源、末端系统和输配系统三方面综合分析，提出了一个有效利用建筑面积、降低运行能耗和费用、绿色环保的空调系统，以期为以后类似项目的空调设计提供参考。该空调系统主要具有以下特点：（1）采用离心式冷水机组+螺杆式风冷热泵的冷热源形式，通过阀门启闭实现制冷、制热工况的转换；（2）在过渡季节，通过控制吊柜式空调机组新风管和回风管上的电动新风调节阀和回风调节阀来实现全新风工况运行，并采用中庭排烟风机兼作排风，来维持室内气压平衡、提升室内空气品质；（3）设置独立的新风－排风全热交换系统。

This paper conducts a comprehensive analysis of the cold and heat source, terminal system and distribution system, with the example of the air conditioning system of a large commercial zone in Chongqing. An air conditioning system is proposed, that can make use of construction area effectively, reduce energy consumption and cost, and be green. The air conditioning system mainly has the following features:(1)It uses centrifugal chillers and screw air source heat pumps as the cold and heat source, and changes the cooling and heating condition through opening or closing the valves; (2)It can achieve the full fresh air operation by controlling the electric valves which installed on the fresh air duct and return air duct of suspended air conditioning units during transitional seasons, and uses the smoke exhaust fans of the atrium to exhaust air in order to maintain indoor air pressure balance and improve indoor air quality; (3)It also has independent fresh air-exhaust air heat exchange system. So it is hoped to provide a reference for the air conditioning design of similar projects in the future.
