Dew Point Temperature Explained | Animation | #hvac #hvacsystem

the dueo temperature is a simple topic to understand the air in our atmosphere contains a mixture of water wapor the measurement of water vapor present in the air is called humidity when the air temperature increases the air molecules expand as the molecules expand more empty space is created in the air this additional space allows for more water vapor to be stored when the air temp tempature decreases the air molecules compress reducing the space available therefore less water vapor can be stored when the temperature is lower we have explained this in our latest video on absolute

and relative humidity the link to the video is in the description please watch it if you are interested when the air temperature decreases the air molecules compress and because there is not enough space to store the water vapor it condenses into water we can see this water wapor condensing in many places the due Point temperature is the calculated temperature at which water wapor condenses out of the air let's say the outside temperature is 33° and the relative humidity is 45% in this case the due Point temp temperature is 19.5 de C therefore when the outside

air temp temperature is 33° C and the relative humidity is 45% the corresponding due Point temperature is 19.5 de c as the air temperature gradually decreases the air molecules begin to compress when the air temperature drops below 19.5 de C the air molecules become so compressed that they no longer have enough space to hold the water vapor causing it to start condensing this condensed water can be seen on all surfaces as due now under the same conditions with an outside temperature of 33° c and relative humidity of 45% let's place a glass of ice water

outside the air molecules near the glass will come into contact with it upon contact the temperature of the air molecules surrounding the glass will rapidly decrease since the due point of the air is 19.5 5° C when the temperature of these air molecules drops below this point the water vapor they contain will condense into water on the glass this is why water condenses on surfaces that have a lower temperature this is how the dueo temperature works there are many online calculators available to measure the dueo temperature by entering the outside temperature and humidity value into

these calculators you can easily find the corresponding due Point temperature value
