某办公楼加班时段空调系统改造方案
Retrofit scheme of air conditioning systems for overtime period in an office building
摘要：
该工程在原有系统基础上增设加班时段空调，满足该空调系统独立运行的前提下尽量保持原有设备和系统的完整性，不影响整个园区空调系统。提出了3种设计方案，遵循尽量利旧、控制成本、节能环保的原则，选择模块化空气源热泵机组方案。介绍了该空调系统的空调负荷、机组安装位置及运行模式。阐述了空气源热泵机组的选择，并计算了其静态回收期。该方案可满足加班时段空调使用需求，静态回收期仅2.39 a。
Abstract：
The project adds the air conditioning system for the overtime period on the basis of the original system to maintain the integrity of the original equipment and system as far as possible under the premise of independent operation of the air conditioning system, and does not affect the air conditioning system of the whole park. Three kinds of design schemes are proposed, and the modular air-source heat pump unit is selected in accordance with the principles of using the old as much as possible, cost control, energy saving and environmental protection. The air conditioning load, installation location and operation mode of the air conditioning system are presented. The selection of the air-source heat pump unit is elaborated, and its static recovery period is calculated. The scheme can meet the demand for air conditioning during overtime, and the static payback period is only 2.39 years.
