For example one can compare a modern cooling method suchĪs adiabatic cooling with compression direct expansion cooling. With Program Psychrometric chart you can easily compare two ways of cooling. There is still 4 g/kg moisture in the air only Comparing efficiency of cooling methods - adiabatic cooling vs. Look that the absolute humidity is not changing. If you want heat 0,883m3/s air from 20 ☌ to 30 ☌ with an air heater than the capacity = 10kW. Than you need:(40 kj/kg -30 kj/kg) * 1 kg Air = 10 kj of energy. If you need to heat 1kg air = 0,883 m3 from 20 ☌ to 30 ☌. Then the water begins to drop down as condensed liquid water. If you bring more spray water into the air then the air can't hold it because the air is already humidified upto 100% and you have reached the boundary. You can practicaly apply this on a hot summer day by spraying water on the roof of you house and through this cool your house.

That's the reason the temperature is getting lower from 34.5 ☌ to 21 ☌. The costs of evaporation heat to vapor water to vapor form. When humidifying air with spray water from H3 to H4 then (15.7-10.3) = 5,4g moisture is brought into the air. Note that the relative moisture humidity is also changes from 20% to 80%. When humidifying air with Steam from H1 to H2 8.5g/kg- 2g/kg)= 6.5g moisture is brought into the air. $15.Screenshots of Psychrometric Chart Pro in different use casesĮxamples of practical use cases of Psychrometric chart Humidifier
