Swimming Pool dehumidifier buying guide

Swimming pool dehumidifier buying guide.

Indoor pool is great facility of comfort which everyone like to have at their homes. But not only cost of constructing indoor pool is high but also its running cost. In this article we will try to guide you buying of dehumidifier for swimming pool. Most of indoor room pool owner and especially residential pool owner do not consider swimming pool dehumidifier while construction of pool. They feel indoor pool dehumidification system is optional item which is not true. For indoor swimming pool, dehumidifier is more important than having air conditioner. When you do not consider pool dehumidifier at construction stage then you double your cost, discomfort and waste of time. It is often observed that client who do not consider dehumidification system at construction stage, comes back to us requesting installation of dehumidifier. We need not to forget that indoor pool room area is a place where two third surface is covered by water. And it is due to natural tendency of water of evaporation, pool area observed with very high humidity which make occupant not only uncomfortable but also they might get health issues. You start observing wet floor, condensation water drops on ceiling and walls, bad smell due to development of fungus in, malfunctioning of electronic good and high electricity bill. Hence we suggest client to must go for swimming pool dehumidifier and that of at initial stage.

Buying dehumidifier for swimming pool? Consider these points……

Following point you should consider while selecting your dehumidification unit

Consider dehumidifier at pool design stage.

We always recommend to plan dehumidifier for your indoor pool at design level itself. Installing unit after damage has been done to your pool area will not help you much. If you plan dehumidifier at design level then you can select right dehumidifier size, right dehumidifier type and incorporate right place to install dehumidifier. It is much easy to install dehumidifier during construction of pool. Especially if you are installing duct dehumidifier then things become very complicate if you like to install dehumidifier in pool area which is in use. During construction you can plan how to place unit, where should be its controller, plan drainage point properly and incorporate electrical supply in your MEP work.

Select right type of indoor pool dehumidifier.

Selecting dehumidifier with right working principle and right type of mounting will not only reduce you initial and running cost but also it will give you good performance. On the basis of working principle there are two type of units; desiccant dehumidifier and refrigerant dehumidifier. We always recommends refrigerant or condensation dehumidifier for indoor swimming pool application. Many companies might offer your desiccant dehumidifier but it is not right solution since desiccant dehumidifier are use for dehumidification at lower temperature such at at cold room. For swimming pool unit based on condensation principle is right solution considering initial and running cost of both types of unit. Secondly you should select right type of unit in terms of mounting. There are generally three types of unit used and those are floor mounted, wall mounted and ceiling suspended type. We recommend ceiling suspended duct type dehumidifier unit for swimming pool. We offer our SPD series pool dehumidifier which will give you good performance. If you considering dehumidification solution at design stage then installation of this type of unit is very easy. Also since it is above false ceiling, it will save floor area and working sound also less. If you have small pool with small pool room size they you can opt for wall mount dehumidifier. This type suitable for pool of surface are up to 50 sq meter. For large commercial pool which has big pool with big open space and go for either ceiling suspended type or floor mount type. We offer our FSD series floor mount dehumidifier which are specially designed for large indoor pool area.

Right specifications for pool dehumidification unit.

Other than calculating right dehumidifier capacity it is also important to pay attention to some of important specification that unit must have for use in  indoor swimming pool for dehumidification. We need to note that humidity level in indoor pool area always high which dehumidifier unit needs to reduce. When high humid air enters into dehumidifier it might cause corrosion to body and coils of dehumidifier. Hence we suggest that dehumidifier body should be made up of powder coated hot dip galvanized steel or ideally of Aluminum. If normal steel used then it might corrodes over period of time. Also unit should protect condenser and evaporator coil from corrosion. Hence we suggest epoxy coating of condenser and evaporator coil

Swimming pool dehumidifier calculation.

This is very important factor while selecting unit. Indoor pool dehumidifier sizing depends on various factory. Mainly it is depend on surface area of swimming pool, pool water temperature, indoor room temperature, type of use.  While doing swimming pool dehumidifier calculation, you need to make sure that at least these four factors are considered. You might find many indoor pool dehumidification calculator online but those might not suitable in your case. Evaporation rate is directly proportional to pool surface area. If pool area is bigger you need high capacity dehumidifier for indoor pool humidity control. If difference between room temperature and pool water temperature is high then it will accelerate rate of evaporation and hence generate high humidity.  Hence we recommend to adjust pool water temperature two degree less than room temperature. This will reduce your indoor pool dehumidifier price. Swimming pool dehumidifier sizing also depend on type of use. If it is residential dehumidifier then use is for few hours and hence dehumidifier for pool room will have low capacity. But if it is hotel or sport complex then we need to consider high capacity commercial swimming pool dehumidifiers.

You should consider all above factory while selection swimming pool dehumidifier. For more information on indoor pool dehumidifier sizing and price please contact us.

Indoor swimming pool humidity control & dehumidifier calculation.

Pool humidity control can be done with help of swimming pool dehumidifiers.

In last many article we understood need of swimming pool dehumidifiers for indoor pool humidity control. In short indoor pool humidity problem can cause mold, fungus, swelling of wood, bad smell of chlorine in your indoor pool room area. Indoor pool dehumidifier helps to remove humidity in pool room which is generated by exposed water surface area of swimming pool. Humidity generated by pool is directly proportional to water surface area and temperature of swimming pool water. Swimming pool humidity control needs efficient pool dehumidification unit. In this article we will learn how to do indoor pool dehumidifier sizing by considering actual data and arrive at proper indoor pool dehumidification calculation.

Data needed for swimming pool dehumidifiers calculation.

As mentioned above pool dehumidifier capacity is mainly depend on surface area of swimming pool and temperature of indoor  water. In addition to this you need to consider additional factors like volume of indoor pool room, type of swimming pool (residential, therapy, hotel or sport) and indoor swimming pool room temperature. Now lets consider a example of residential swimming pool. Current indoor pool humidity level is around 90% RH and owner wants it at comfortable level. For indoor pool rooms and spa it is expected that indoor swimming pool dehumidifier should reduce humidity to 60% RH. Size of swimming pool is 10 meter by 5 meter which exposed water surface area of 50 square meter. Air conditioner of indoor pool area maintaining room temperature of 25 degree Celsius. Maximum temperature setting for pool water is not more than 30 degree Celsius.

Formula for calculation of indoor pool dehumidifier size.

Here we are going to use simplified as indoor pool dehumidification calculator which is derived considering all factors effecting capacity of dehumidifier. Same formula can be use for capacity calculation of residential indoor pool dehumidifier and commercial dehumidification units. Formula for calculation of indoor pool dehumidifier is as follow:

W= 15 x [Ax(Pw-Pa)Fa]

Where:

W= Evaporation rate in kg/hr or liter/hour.

A= Water surface area of indoor swimming pool in square meter.

Pw= Saturation vapor pressure taken at water surface temperature.

Pa= Saturation pressure at room air dew point.

Fa= Activity factor depend on type of swimming pool.

Table for calcuation size of indoor pool dehumidifier for pool humidity control.To get capacity of indoor swimming pool dehumidifier let put values in above formula.  Area of swimming pool we can get from site visit. To find out Pw we need to refer table 1, from which we can find out its value corresponding to temperature of swimming pool water. Pa value can be find out from Table 2. Corresponding value of Pa with respect to room temperature can be find out. Activity factor is depend on number of people using room and their activity. Hence type of swimming pool classified into broad seven types where number of people using indoor pool varies and activity factor has been mentioned.

From Table 1: value of Pw at swimming pool water temperature of 30 degree Celsius is 0.0425

From Table 2: Value of Pa at indoor temperature of 25 degree Celsius and required humidity of 60% RH is 0.0190

Since it is residential pool, from activity factor table we can consider activity factor Fa=0.5

When we put all value in above formula, we get capacity of 8.81 liter per hour which equals to 202 liter per day.

Same calculation can be use of pool and spa dehumidifiers.
