Problems solved by technology
However, the calculation of smoke exhaust efficiency in practical engineering applications is only related to the total smoke exhaust volume and total smoke production. This single general evaluation index still fails to reflect the safety level that the smoke control system can achieve and the performance of each component element. However, it is impossible to give a scientific and reasonable comprehensive assessment of the performance of the smoke control system, and it is not yet instructive and pertinent for troubleshooting the root cause of the problem and proposing rectification measures.

Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0035] The present invention proposes a comprehensive evaluation method for the performance of a smoke control system, which is mainly used to guide the optimization of the setting of the smoke control system in actual construction projects, improve the effect of smoke control, and strive for safety for personnel evacuation and fire rescue under fire. Calculation and evaluation process of the present invention (as figure 1 shown):
[0036] (1) Establish evaluation indicators, including the maximum smoke control safety S of the smoke control system max , smoke control safety S, smoke control efficiency η F ;
[0037] (2) Clarify the respective benchmark values of the above three evaluation indicators;
[0038] (3) Formulate a comprehensive evaluation table for the performance of the smoke control system according to the benchmark value;
[0039] (...

A method for comprehensively evaluating the performance of a smoke control system proposed by the invention relates to the technical fields of fire science and fire engineering. The method includes step A: establishing an evaluation index, step B: formulating a comprehensive evaluation table, step C: calculating the evaluation index, and step D: comprehensively evaluating the performance of the smoke control system. This method clearly subdivides the evaluation index, and the established index not only evaluates the smoke control efficiency of the system, but also takes into account the evaluation of fire safety; and the relationship between the calculated value of the index and the reference value is considered in detail in the comprehensive evaluation , and make reasonable divisions, the evaluation conclusions and suggestions drawn from this are scientific and instructive, and can finally achieve effective rectification and optimization of the smoke control system, improve performance, and ensure safety. The invention is easy to master, has high engineering applicability, has important reference value and significance for improving the fire protection design, transformation and detection level of actual engineering, and can generate good economic and social benefits.
Description
technical field [0001] The invention relates to the technical fields of fire science and fire engineering, in particular to a method for comprehensively evaluating the performance of a smoke control system. Background technique [0002] For all kinds of buildings and tunnels, the space is relatively closed, and the smoke generated during a fire is not easy to spread outwards. As the fire develops, it will continue to accumulate and spread, resulting in high smoke temperature and high concentration of toxic gases, seriously endangering personnel. Safety of life and safety of building structures. [0003] In order to effectively control the high-temperature smoke in a fire, so as to ensure the safe evacuation of personnel and avoid damage to building structures, the role of the smoke control system is very important, and the performance of the smoke control system determines its role. How to make a scientific and reasonable evaluation of the performance of the smoke control s...
