摘要：本次设计为上海某办公楼中央空调系统，通过合理的设计，为办公楼内的工作人员提供良好舒适的工作环境。本次设计通过对比 VRV、VAV和风机盘管加新风系统的优劣，最终确定采用风机盘管加新风系统。新风与回风混合后直接送入室内。冷热负荷由各个房间内的风机盘管承担。新风机组设置在天台，采用多级过滤结合光催化空气净化方案，在一定程度上保证了室内空气的洁净度。通过计算，本办公楼的夏季总冷负荷为304kw，故选用 MAC1040BR 风冷模块机组为中央空调系统提供冷热水，此模块机组工作温度范围广，冷热水供应稳定。本系统的优势在于每个末端都有独立的开关控制，保证了每个房间都可以进行独立的温度控制，防止了空气的交叉污染。 本次设计内容包括：空调冷热负荷的计算、空调系统的确定、冷热源的选择、风机盘管的选择、风系统与水系统的水力计算、风系统与水系统的布置、室内气流组织的确定、新风系统的空气净化等内容。 41379

The Design of Central Air Conditioner and Purification System for Office Building
Abstract: The design of an office building in Shanghai central air conditioning system, through rational design, office building for staff to provide a good and comfortable working environment. The design by comparing VRV, VAV and fan coil plus fresh air system, the pros and cons, and ultimately determine the use of air fan coil system. Directly into the new indoor air and return air mixing. Fan coil cooling and heating load borne by each room. New air handling units set up on the roof, the use of multi-stage filtration combined photocatalytic air purifier program, to a certain extent to ensure the cleanliness of indoor air. By calculation, the total cooling load of the building in summer is 304kw, so use MAC1040BR cooled module units provide hot water for the central air conditioning system, sub-module units wide operating temperature range, hot and cold water supply is stable. Advantages of this system is that each terminal has a separate switch control, to ensure that each room can be independent temperature control, to prevent cross-contamination of the air. The design includes: determining air conditioning heating load calculation, air conditioning system, hot and cold source selection, the choice of fan coil arranged hydraulic calculation air system and water system, air system and water systems, indoor air the determination of the new air system air purification and so on.
