1.可能跟空氣壓力有關,那如果說我也把壓力也設在固定某一範圍內,飽和溼度是不是能計算出來
2.我查過溫濕球量測相對濕度的方法,由此我可以得知--當乾球溫度固定(應該是指當時室溫)濕球溫度會因濕度不同而改變,但是我該如何得知濕球的溫度在乾球溫度固定時的溫度上限是多少而查出飽和濕度

21攝氏度

55

2立方米

1，米寬1，身高 2

，需要添加到房間內的空氣，以實現上述相對濕度。

 Outside temperature: °C Relative humidity outside: % Calculated grams of H2O per kg of air: With the following fields you can calculate the (new) relative humidity is the outside air is heated in a closed space (room, office, factory hall e.g.).: Set temperature inside closed space: °C Calculated relative humidity inside closed space: Setpoint relative humidity inside closed space: % Volume of space: m3 or length x width x height m length, m width, m height Required amount of H2O (gram) per kg air to reach the desired relative humidity: which equals for the space mentioned above:

At an adopted weight of one cubic metre of air of kg/m3, needs to be added to the air within the room to achieve the above-mentioned relative humidity.

Imagine: there is a building in which % of the air is recicled and is refreshed by outside air. How much moist must be added to this air?  must be added.

vp = (RH/100)*((6.107*Math.exp((7.5*T)/(237.3+T)*Math.LN10)/10));其中 RH是濕度值, T是攝氏溫度, 公式怎麼來的我不清楚 (只是幫你找出來)

混和氣體中水蒸氣的分壓等於同溫度下純水的蒸氣壓時，此時稱此混合
氣體之濕度為飽和濕庋。
公式:

HS=

absMoisture = RH*0.042*Math.exp(T*0.06235398);

就可算出需要添加多少水會達到飽和!
