【摘要】：目前世界各地,火災(zāi)頻繁發(fā)生,消防服是戰(zhàn)斗在消防一線的消防員的生命安全重要保護(hù)裝備。在滅火戰(zhàn)斗中,消防服的熱防護(hù)性能和舒適性能不僅關(guān)系消防員的工作效率而且直接危及消防員的生命安全。所以,消防服整體的熱防護(hù)性能與舒適性能的評價顯得尤為重要�，F(xiàn)有的消防服熱防護(hù)性能評價都是在穩(wěn)定環(huán)境狀態(tài)下進(jìn)行的,并不能客觀真實(shí)的模擬消防員接警后由普通環(huán)境到進(jìn)入火場這一動態(tài)過程。本文研究了,基于動態(tài)條件下,消防服整體的熱防護(hù)性能與舒適性能,探究了消防員穿著消防服進(jìn)入火場,消防員核心溫度、皮膚溫度、消防服內(nèi)層溫度和消防服外層溫度隨時間的變化規(guī)律。通過構(gòu)建實(shí)驗(yàn)平臺,基于出汗暖體假人系統(tǒng),提出了一種新的測量消防服整體防護(hù)性能的方法,并提出一個客觀參數(shù)核心溫度變化率CTCR來測量消防服整體的熱防護(hù)性能。探究了基于動態(tài)條件下,消防服熱防護(hù)性能影響因素,同時基于動態(tài)條件下對消防服熱防護(hù)性能與舒適性能進(jìn)行了客觀和主觀評價。首先本文自行搭建了兩個實(shí)驗(yàn)設(shè)備,隔熱保溫罩與閃爆輻射熱源,與人工氣候室、出汗暖體假人系統(tǒng)一起構(gòu)成了本研究的實(shí)驗(yàn)平臺。文中選用了三套常見的現(xiàn)役消防服,在動態(tài)條件下,研究了其熱防護(hù)性能與舒適性能,并對每一套消防服的熱阻、濕阻、透氣性能、透濕性能、厚度、重量進(jìn)行了測試。結(jié)果表明F2消防服的核心溫度變化率CTCR最小,其熱防護(hù)性最好,綜合比較F2消防服的舒適性能最優(yōu)。在動態(tài)條件下,消防服的熱防護(hù)性能與消防服的熱阻、濕阻、透氣性能、透濕性能有關(guān),且都與其熱護(hù)性能正相關(guān),特別地?zé)嶙璧挠绊懶Ч顬槊黠@,熱阻越大消防服的動態(tài)熱防護(hù)性能越大。最后,在動態(tài)條件下,對三套消防服的熱防護(hù)性能與舒適性主觀評價進(jìn)行了真人實(shí)驗(yàn),結(jié)果表明F2消防服的熱防護(hù)性能與舒適性能都是最優(yōu)的,F1消防服的熱防護(hù)性能與舒適性能次之,F3消防服的熱防護(hù)性能與舒適性能最差,主觀評價結(jié)果與基于動態(tài)條件下消防服熱防護(hù)性能與舒適性能客觀評價結(jié)果一致。
[Abstract]:At present, fires occur frequently in various parts of the world. Fire fighting clothing is an important protection equipment for the lives of firefighters fighting on the front line of fire. The performance of thermal protection and comfort of fire fighting clothes is not only related to the work efficiency of firefighters, but also directly endangers the life safety of firefighters. It is particularly important to evaluate the overall thermal protection performance and comfort performance of fire fighting clothing. The existing evaluation of thermal protection performance of fire fighting clothing is carried out in a stable environment. It is impossible to simulate the dynamic process from ordinary environment to fire scene after firemen receive alarm objectively and realistically. This paper studies the thermal protection performance and comfort performance of the whole fire fighting suit under dynamic conditions. The changes of firefighters' core temperature, skin temperature, inner layer temperature and outer temperature of firefighting suit were investigated. In this paper, a new method for measuring the overall protective performance of fire fighting clothing is proposed, and an objective parameter, the core temperature change rate (CTCR), is proposed to measure the overall thermal protection performance of the fire fighting suit. At the same time, the thermal protection performance and comfort performance of fire clothing are evaluated objectively and subjectively on the basis of dynamic conditions. Firstly, two experimental equipments, thermal insulation cover and flashover radiation heat source, are built in this paper. Together with the artificial climate room, the sweating and warm-body dummy system constitutes the experimental platform of this study. In this paper, three sets of common active fire fighting suits are selected, and the thermal protection performance and comfort performance are studied under dynamic conditions. The thermal resistance, moisture resistance, air permeability, moisture permeability, thickness and weight of each suit are tested. The results show that the core temperature change rate of F2 fire suit is the smallest, and its thermal protection is the best. Under the dynamic condition, the thermal protection performance of the fire suit is related to the thermal resistance, moisture resistance, air permeability and moisture permeability of the suit, and all of them are positively related to its thermal and protective performance. In particular, the effect of thermal resistance is the most obvious, and the larger the thermal resistance, the greater the dynamic thermal protection performance. Finally, under dynamic conditions, the subjective evaluation of thermal protection performance and comfort of three sets of fire fighting clothing is carried out in a real person experiment. The results show that the thermal protection performance and comfort performance of F _ 2 fire suit are the best, and the thermal protection performance and comfort performance of F _ 1 fire suit are the worst, and the thermal protection performance and comfort performance of F _ 3 fire suit are the worst. The subjective evaluation results are consistent with the objective evaluation results of thermal protection performance and comfort performance of fire fighting clothing under dynamic conditions.
