Dehumidifier Capacity Calculation

Explanation of result

This means that liter of water has to be removed from the air to achieve a humidity of under the present conditions given by you. Hence while selecting you have to select a dehumidifier accordingly. For all de humidifiers, the capacity is defined as liter per hour, kg per hour etc.

Calculation method


Present humidity and desired humidity are defined as %RH which means as a percentage of the total volume of the air. This has to be converted into absolute humidity, which means real amount of moisture content in terms of grams per each cubic meter. The difference of the present humidity level and the desired humidity level is the amount of water to be removed.

Note:The calculation is true to the best of our knowledge at the time of development and we bear no contractual obligations whatsoever for the results or the calculation method.


Brief explanation of the input fields are given below
a. Present temperature (°C) is the normal working temperature of the area in degree centigrade
b. Present humidity is the humidity level measured in %RH. You can measure the same using a hygrometer or humidity data logger
c. Desired humidity is the humidity level to be achieved after installation of the de humidifier.
d. Room size has to be given is meters or if you know the volume, you can input the volume in cubic meters.
