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?

dehumidifier home humidity-1While selecting dehumidifier for home we need to make sure that capacity should be sufficient so that it an remove humidity at the same time dehumidifier should be able move over certain amount of air in certain period of time. In simple word we need to decide liter/day extraction capacity of and Air flow volume of dehumidifier. 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.

dehumidifier sizing guideline by AHAM.

 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.

Housing and body.

Body of SPD series indoor swimming pool dehumidifier is made from adopts steel frame structure, it is compact, with strong corrosion resistance, and consists of anti-cold bridge device, effectively preventing the "condensation" phenomenon. With removable flush seamless access panels, it is very easy for maintenance. Water tray equipped ensures that all condensate water drain out, preventing water stagnation.

Duct

Inlet and outlet duct size is different across different capacity of dehumidifier depending on air flow. Removable filter is equipped in each air inlet hole, 35% filtration efficiency. At supply duct a centrifugal fan with steel volute and blades is provided SPD-136L swimming pool Dehumidifier in UAE.which ensures high efficiency and low noise.

Refrigeration system

In SPD series Pool Dehumidifier extra use energy-saving heat exchanger, integrated using a liquid separator reservoir and heat exchangers, it can effectively regulate the fluid flow volume, maximizing freezing capacity, and ensuring compressor operate well. Meanwhile, dry filter was introduced in this system to prevents clogging/impurities in expansion valve or capillary. It equipped with patented defrosting structure, it brings stable operation of refrigeration system. Hydrophilic membrane fin(heat exchanger), heat transfer efficiency increases by 20%. Good insulation material also increases insulating effect by 15%.

Compressor

Compressor is the core part of this dehumidifier. It directly impact dehumidifier’s performance. It is the heart of this dehumidifier, provides powers for whole system. SPD series swimming pool dehumidifier consists of only use the international SPD-136L swimming pool Dehumidifier in Qatar, Kuwait, UAE,OMAN.well-known brand compressors: Panasonic compressor and Dakin compressor.

Throttling device system

Throttling device system is one of four important system in refrigeration systems. It will reduce the liquid refrigerant(coming from condenser)’s high pressure, make the refrigerant absorb heat under low pressure(low temp) while vaporization. Anyway, it is one important component to ensure high pressure in condenser and low pressure in evaporator. As a result of direct expansion way, small cooling loss, high efficiency, it also prevents fluid striking and over-heating. Expansion valve superheat stable, the system is stable.

 Protection devices

  • De-humidifier controller is powerful, high overall operating performance. Motor overload and short circuit protection is introduced too; Motivation switches are provided for overload and short circuit protection.
  • SPD-136L swimming pool Dehumidifier in Kuwait, UAE, Qatar,OMAN.Starting-up delay protection: If the de-humidifier is cut off normally, it will take 3 minutes when turn it on again.

  • Fans selection: Fan can stop/keep running while the setting RH is reached, customer have can set it according to their demands.
  • High temperature protection: Prevent the compressor running continuously at high temperatures.
  • Low pressure protection: Prevents the de-humidifier running without refrigerant; avoids compressor burned.

Selection De-humidifier for swimming pool design

While selecting dehumidifier for swimming pool we need to pay attention to selection of capacity and mounting of dehumidifier. Capacity of pool dehumidifier is depends on area of swimming pool, temperature of swimming pool water, number of occupants & indoor room temperature.  bigger the swimming pool area and higher the swimming pool water temperature, evaporation will be take place at more faster rate and humidity will increase. Ceiling mount dehumidifier is always recommended for faster dehumidification.
