北京某医院改造工程中央空调系统设计 摘要 本设计为北京某医院改造工程中央空调系统设计。该建筑为综合性建筑，共四 层，其中一、二层为诊疗部，三、四层为住院部，ICU 病房及手术室设在四层。建 2 筑面积约为3500m 。 根据工程要求，选用 VRV 变冷媒流量空调系统，各房间独立控制，满足不同 房间、不同温度的需求。选用大金 VRV 机组，为用户提供节能、舒适、运行平稳 的空调系统。 根据建筑特点及房间负荷计算，室内机多采用天花板内藏直吹式，个别房间采 用天花板嵌入式（四向气流和两向气流）。手术室和 ICU 病房设有新风 VRV 以满 足洁净度需要。整个系统使用室外 8 台，室内机 70 台，新风VRV 3 台，满足该楼 夏季供冷需求。 关键词：中央空调，VRV ，负荷计算 I 北京某医院改造工程中央空调系统设计 Abstract This is a central air-conditioning system design for a renovated hospital project in Beijing. The building is integrated architecture. It has four stories. The first floor and the second floor are used for clinics, and the third floor and the fourth floor for the inpatient department. ICU wards and operating room are in the fourth floor. The construction area 2 is approximately 3500 m . According to the request, it has selected VRV air-conditioning systems. It can control each room independently, so it can meet to the need of the different rooms and the different temperature. Daikin VRV units had been selected to provide users with energy-saving, comfortable, smooth operation of the air-conditioning system. According to architectural features and room cooling load, most of the indoor units are the ceiling internal mounted direct blow type, and the indoor units of individual rooms are ceiling embedded type (four-way airflow and two-way-airflow). To meet the needs of cleanliness, the new wind VRV is used at ICU wards and operating room. The whole system use 8 outdoor units, 70 indoor units, 3 new wind VRV, to meet summer cooling needs of the building.
