Difference between desiccant & refrigerant type Industrial dehumidifier.

Dehumidifier are classified on basis of principal of working, type of its use and type of mounting. On basis of use it commonly classified as home dehumidifier, industrial dehumidifier or commercial dehumidifier and Swimming pool dehumidifier. On basis of Mounting it defined as portable dehumidifier, ceiling mount, wall mount and floor mount dehumidifier. On basis of working principle dehumidifiers are mainly classified into refrigerant type and desiccant type dehumidifiers. In this article we will discuss difference between refrigerant type and desiccant type dehumidifiers.

Principle of Working or Refrigerant and Desiccant commercial dehumidifier.

Refrigerant type dehumidifier consists of compressor, condenser and evaporator coil. Humid air suck inside dehumidifier which passes over cold condenser coil where humidity in air condensed into physical water. This water stored in built in tank and dry air thrown out. Desiccant type dehumidifier consists of desiccant wheel, motor, process fan, reactivation fan, heater etc. Desiccant rotor

moves continuously with help of motor-belt arrangement. Process fan draws humidity air which passes through desiccant wheel and humidity for air get absorbed by desiccant wheel. Dry air then thrown out. Due to absorption of humidity, desiccant wheel get wet which get dry by passing hot air with help of reactivation heater. wet air then thrown out of dehumidified space with help of reactivation fan.

Differences between refrigerant and desiccant industrial dehumidifier.

There are many distinguishing differences between desiccant and refrigerant type commercial industrial dehumidifiers. We will see all differenced between these commercial duty dehumidifiers one by one.

  • Commerical Dehumidifier for swimming pool banner
  • Warehouse Dehumidifier supplier in Dubai.

Area of Use of refrigerant and desiccant commercial dehumidifier.

Refrigerant type Industrial portable dehumidifier are use in high temperature and high moisture areas where dehumidification to be achieve. Using refrigerant type large dehumidifier for low temperature areas can cause formation of ice on its coil which can reduces its dehumidification capacity. While desiccant type portable commercial dehumidifiers are use in low temperature and low moisture areas where dehumidification to be achieve. with help of desiccant type commercial dehumidifier we can achieve low humidity as 1% RH.

Dehumidifier price.

Desiccant type dehumidifier are more costlier than refrigerant type dehumidifier. for same capacity dehumidifier cost of desiccant dehumidifier can be three times than that of cost of refrigerant type dehumidifier.

Cost of Running.

Desiccant type commercial dehumidifier needs more electrical power than equivalent capacity of refrigerant type industrial dehumidifier.

Temperature of dry air.

In desiccant dehumidifier, heaters and fans has been used during process of dehumidification. Due to this dry air coming out of desiccant dehumidifier has high temperature which can increase temperature of space by 3 to 5 degree Celsius  which can become major issue if dehumidifier serving to large area. This will increase cost of air conditioning. While refrigerant type industrial dehumidifier gives out warm air which can increase temperature of space by 1 to 2 degreee Celsius only.

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.

Industrial or Commercial Dehumidifier: As name suggested these dehumidifiers are use in industrial process applications. Rating of these dehumidifier if from 30 to 1200 liter/day. These dehumidifier can be of portable type (with wheels) for fixed type (wall mount, ceiling mount or floor mount). Industrial dehum has bulky, strong mental body and it provided with strong wheels if it is portable. Control panel provided with basic functions. Filter provided I these unit is of basic type. only humidistat provided on control panel to set required humidity.

Indoor Swimming Pool Dehumidifiers: This dehum use in swimming pool, spa and Jacuzzi indoor areas since all these areas has water bodies (heated water) which has high humidity due to fast water evaporation. Generally Ceiling mount, roof mount or wall mount dehumidifier are preferred. Wall mount units has limitation on capacity hence it use for small home swimming pool. Roof mount dehumidifier can be use for large Olympic size pool. while ceiling mount dehumidifier can be use for all type of pools and gives faster result than other two.

Types of Dehumidifier based on its working principle.

Based on working principle Dehumidifiers are broadly of following two types:

Refrigerant type Dehumidifier: It is also called as condense drying dehumidifier or mechanical dehumidifier or condensation type dehumidifier. It uses refrigeration cycle to remove humidity from air. It consists of evaporator and condenser coil. Fan draw humid air to evaporator where air cooled below dew point and condensation of moisture happens. condensate water collected in tank. then dry air pass through condenser coil where it heated and return to room to pick up humidity. This type of equipment is more economical in terms of initial cost and operation cost. Refrigerant type units are more economical when dehumidification has be done at high temperature and high humidity level. It consumes less power than desiccant type unit.

desiccant and refrigerant type dehumidifier workingDesiccant type Dehumidifiers: This types of units are economical than condensation type when dehumidification has be done at low temperature and low humidity level. It consumes more power than refrigerant type unit. Initial and working cost of this type dehumidifier is higher than refrigerant type unit. This type unit consists of rotating desiccant wheel. Humid air drawn to rotating desiccant wheel with help of process fan where humidity in air absorbed by desiccant wheel and heated dry air release in room. Due to absorb humidity desiccant wheel becomes wet and to dry wheel heated reactivation air passes through desiccant wheel and wet air release outside room with help of reactivation fan.
