The First Opening Segment Of Hangzhou Metro Line 2 Ventilation And Air Conditioning Project Research

Metro construction is a complicated system engineering, ventilation and air conditioning engineering while in the final stage of the whole project, but its importance as before any of the project.Because the subway system is directly related to the project delivery after use, security, and degree of human nature, its quality is also to a certain extent, determines the overall quality of metro engineering.Alleged ventilation engineering, it is in the local place or the whole room does not conform to the hygiene standards of foul air processed to achieve discharge standard back to (referred to as the exhaust), outdoor fresh air or purified conform to the requirements of the health of the air into the indoor (called into the wind, make indoor air parameters conform to the requirements of the health, assure indoor personnel’s physical health. Air conditioning engineering refers to the through technical means, for a relatively closed environment of temperature, humidity, air flow velocity and cleanliness to adjust and control, so as to satisfy the function of the safety and comfort. Subway ventilation and air conditioning project of high technical difficulties, strict standard, so this special research. This paper selected the first opening segment of hangzhou metro line 2 ventilation and air conditioning project as an example, study on special system for the project.In this paper, besides introduction and conclusion can be divided into three parts:The first part, the first opening segment of hangzhou metro line 2 ventilation and air conditioning ventilation and air conditioning projects status quo analysis, this paper introduces the first opening segment of hangzhou metro line 2 basic situation of the ventilation and air conditioning project engineering, and the main content, analyses some problems existing in the management of the engineering project, so as to avoid subsequent of hangzhou metro construction ventilation air conditioning construction provides a powerful reference for the same problems again.The second part, the first opening segment of hangzhou metro line 2, ventilation and air conditioning ventilation and air conditioning projects status quo analysis, looked at the first opening segment of hangzhou metro line 2 ventilation and air conditioning project implementation process, including the subway ventilation and air conditioning engineering project management organizational structure design of air conditioning system construction method and construction preparation process, ventilation, air conditioning system, ventilation, air conditioning system construction method construction process, ventilation, air conditioning system, ventilation system, ventilation, air conditioning water system construction technology and technical measures of construction technology and technical measures, ventilation, air conditioning system equipment installation construction technology and technical measures such as problems, fully shows the basic content and technical requirements of the engineering.The third part, the first opening segment of hangzhou metro line 2 of ventilation and air conditioning project evaluation index system, investigated the first opening segment of hangzhou metro line 2 of ventilation and air conditioning project evaluation index system, including the evaluation index system, specific content and basic method, which provide the complete and feasible for the evaluation of engineering standards.This study is not only a reflection and summary of the project, but also for our future subway ventilation and air conditioning project engineering construction provides the guidance of pragmatic.
