Abstract

<p>The main purpose of this article is to describe the principles of CO ventilation in car parks and to provide a brief description of smoke extraction and control system. It provides information on the possibilities provided by jet ventilation. In closed car park, inRomania, we use for CO and smoke extraction system fans and a lot of ducts. In many country of theEurope, they use for this jet ventilation system, without ducts, characterized by low installation and energy costs.</p>

Highlights

Cars have become a natural part of everyday life
Based on experience in the densely populated and the large cities where space is at a premium, the designers have developed car park ventilation systems for carbon monoxide (CO) extraction and smoke control in case of fire
For example: there is no or insufficient room for inlet and/or exhaust ducts, there is no guarantee that the system will provide sufficient ventilation, so-called "dead" corners with little or no ventilation may result, there is no room for ducts, smoke control in case of fire is not considered during system design, the possibility of regulating the level of ventilation in response to variable requirements is not considered, fire protection installations such as fire doors and fire walls prevent an unobstructed view of the car park [2, 3 and 4]

Summary

INTRODUCTION

Cars have become a natural part of everyday life. Parking facilities are in great demand, in cities and large towns. Based on experience in the densely populated and the large cities where space is at a premium, the designers have developed car park ventilation systems for CO extraction and smoke control in case of fire. They require no ducts in the car park, like in Romania, and are extremely flexible [1]. Requirements are more specific in countries with a longer tradition of building car parking facilities and more experience in their design. Closed car parks are characterized by: a) outside walls are closed; b) only a single outside wall with ventilation openings; c) ventilation openings, if any, that do not meet the requirements on open car parks; d) underground car parks with no ventilation openings; e) a standard distance to neighboring buildings; f) partitioning walls that impede natural ventilation
