Abstract-- Safety system including ventilation systems and fire protection systems for an underground car park to be constructed in .
摘要- 安全系统的建造包括通风系统和一个地下停车场消防系统
Hong Kong, are discussed and their design illustrated. The thermal environment
在香港,对于他们的设计进行了讨论和说明。
at the occupied zone was assessed by using omputational fluid dynamics (CFD). The predicted air speed was used to calculate the mean age of the air and the percentage of people dissatisfied with the air quality. 预测的风速一般是通过计算空气的平均年龄和与空气质量不满意的百分比。
The probable fire environment was studied by using a fire zone model.
对于火灾的可能环境是通过用火区模型来研究的。
Designs for smoke control and the thermal sensitivity of the sprinkler heads were evaluated. 烟雾控制和喷头热灵敏度设计进行了评价。
Based on the investigations, designs on the fire protection and ventilation systems are mended for providing a healthy and safety environment in this underground car park. 在调查基础上,对防火及通风系统设计建议,以便在这个地下停车场有健康和安全的环境
A field survey of 27 enclosed car parks was carried out, and correlation equations fitted from this paper we used to assess the fire safety aspects of those car parks.
27个封闭的停车场进行了实地调查和相关相关论文中,我们从这个方程来评估这些停车场的配备消防安全方面。

Introduction (简介)
Any (at least 300) big underground car parks are found in the Hang Kong Special Administrative Region (HILSAR, formerly Hong Kong). Most ofM them are constructed at the basement levels mercial or residential buildings bat problems related to indoor air quality, especially the carbon monoxide concen- tration emitted by cars, mechanical ventilation systems must be installed to supply fresh air 1. Fire safety also has to be dealt with carefully. The required fire services
installations are the fire hydrant, hose real, sprinkler and fire detection system. If the volume of the space is greater than 7,000 m 3, a smoke extraction system is required 2. The mechanical ventilation
