【摘要】：為了減小礦井濕空氣熱濕參數(shù)計(jì)算誤差,通過(guò)系統(tǒng)梳理熱濕參數(shù)計(jì)算方法,考慮礦井濕空氣溫度、濕度、壓力隨開(kāi)采深度增加而增大的特點(diǎn),制作具有普遍適用性的濕空氣不同大氣壓溫濕圖。分析了礦井濕空氣熱濕參數(shù)受空氣溫度、濕度、壓力的影響情況,提出實(shí)際計(jì)算時(shí)應(yīng)避免使用通用參數(shù)計(jì)算所引起的誤差,如忽略空氣壓力在不同深度的變化,將會(huì)產(chǎn)生含濕量與比焓計(jì)算的較大誤差。
[Abstract]:In order to reduce the calculation error of heat and humidity parameter of mine wet air, the characteristics of temperature, humidity and pressure of mine wet air are considered by systematically combing the calculation method of heat and humidity parameter with the increase of mining depth. Make the universal applicability of wet air temperature and humidity map at different atmospheric pressure. This paper analyzes the influence of air temperature, humidity and pressure on the heat and humidity parameters of mine wet air, and puts forward that the errors caused by the general parameter calculation should be avoided in actual calculation, such as neglecting the variation of air pressure at different depths. There will be large errors in the calculation of moisture content and specific enthalpy.
