Industrial dehumidifier capacity selection.

Selecting capacity of industrial dehumidifier is totally different than that of selection size of home dehumidifiers. Major difference is while selecting capacity of commercial dehumidifier not only we need to make note of factor that effecting humidity but also factors effecting industrial process before and after installing a dehumidifier. In this article we will try to understand approach to decide  suitable type and capacity of dehumidifier.

Factor effecting Capacity of Commercial dehumidifier.

CD-85L INDUSTRIAL DEHUMIDIFIER Capacity of dehumidifier is majorly depends on following parameters:

1) Volume of the space which need to be dehumidify: Capacity of industrial dehumidifier directly proportional to volume of space.

2) Temperature in space:  This parameter not only effect size of dehumidifier but also it is deciding factor for type of dehumidifier. If temperature in space which needs to be dehumidify is lower than 15 deg. C then in stead of traditional refrigerant type of dehumidifier,  we should recommend for desiccant type of dehumidifier.

3) Current humidity level in space: If present humidity level in space is high then dehumidifier has to do extra job to remove humidity from air and hence dehumidifier capacity will increase.

4) Fresh Air Added in Space: If HVAC system in facility is taking fresh air from outside and this fresh air is not treated then outside fresh air will bring humidity along with it. Hence amount of fresh air get added in system will also effect sizing of dehumidifiers.

5) Number of people working in space: Human body adds humidity in environment. If people in space is doing physical work then humidity added by human body will be more.

Dehumidifiers of home should size with required humidity of 50 to 60%RH. Portable commercial dehumidifiers should be size with required humidity of application.

Dehumidifier capacity selection.

It is always a big challenge for users like us to select capacity of dehumidifier for our home. Once we decided to go for new dehumidifier unit then we always faced with common question of which capacity. In this article we will try to understand how to decide capacity and airflow of portable dehumidifier for home.

What home dehumidifiers should have?

Extraction capacity generally mentioned in terms of liter/day or pints/day. It is nothing but maximum amount of water that dehumidifier can extract from air in one day. Air flow volume is important to consider since moisture from air will get extracted only if air passes through dehumidifier. More the Air flow, more air will pass through dehumidifier and moisture level from air will come down quickly. Air flow volume mentioned in terms of Cubic Feet per Minutes (CFM).

Selecting Liter/day Dehumidifier Size.

As long as dehumidifier for home is concerned, Association of Home Appliance Manufacturers (AHAM) has made job very easy.  AHAM offered easiest dehumidifier buying guide. AHAM has recommended capacity of dehumidifier depending on size of room and humidity level in room. Capacity of dehumidifier is directly proportional to humidity level in room and size of room. is Depending on level of humidity and its symptoms AHAM divided area in following four types:

1) Extremely Wet Area: Areas with extremely high humidity level with Wet Floors and High-Load Conditions.

2) Very Wet Area: Areas with high humidity which tends to condensation water drops formation on walls and seepage on walls.

3) Very Damp Area: Common symptoms of these areas are bad odour from carpet, clothing, sofa and damp spot of walls.

4) Moderately Damp Area: In such areas you feel uncomfortable and with smell.

 

Depending on Humidity levels (as mentioned above) and size of room, AHAM offered following guideline to select size of dehumidifier.

 Selecting Air flow volume for dehumidifiers.

CFM Air flow volume needed in room is decided with help of square foot area of room and humidity level in room. Air flow volume is directly proportional to square feet area of room and humidity level in room. Square feet area of room determines how much air should pass through dehumidifier while humidity level in room determines how many times this air should pass through unit in hour. This term is denoted as ACH or air changing per hour.

Air flow volume in CFM can obtain by multiplying square foot area of room and recommended ACH for that room. Recommended ACH from different areas as follow:

1) For Extremely wet area: These are areas where humidity level in range of 90% to 100% RH. Recommended ACH is 6.

2) For Very wet area: These are areas where humidity level in range of 80% to 90% RH. Recommended ACH is 5.

3) For Very Damp area: These are areas where humidity level in range of 70% to 80% RH. Recommended ACH is 4.

4) For Damp area: These are areas where humidity level in range of 60% to 70% RH. Recommended ACH is 3.

By multiplying Area of room in square feet to Recommended ACH, one can get Air flow Volume for Dehumidifier.
