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.
