国外变风量空调系统设计理念探讨与借鉴

Discussion and reference of VAV system designing ideas from some foreign countries

在变风量空调系统设计方面,北美国家多采用大型多层式空调系统,低温送风、高速送风和再热;日本则常采用小型分散式空调系统,常温送风、低速送风和供冷与供热分开设置。提出了应在借鉴国外各种技术特点的基础上,结合我国具体工程的气候环境、能源供给、投资能力以及管理水平等情况,设计变风量空调系统。

On VAV systems design, in North American countries, large multi-storied air conditioning systems are usually adopted, in which low temperature air supply systems, high-speed systems and reheat control systems are involved, while in Japan, commonly adopted are small decentralized systems, in which normal temperature air supply systems, low-speed systems and cold-heat separated systems are applied. Therefore, puts forward that concrete conditions such as climate, energy-supply, investment, and management quality should be taken into consideration based on the reference of technical characteristics abroad on VAV system design.
