How to determine the amount of evaporation from indoor swimming pool?

How much evaporation does my indoor pool have?

Knowing the production of water evaporation that is created in the indoor swimming pool is essential to determine how to choose the swimming pool dehumidifier best suited to the conditions of use and the characteristics of the pool. The equipment must be efficient and powerful enough to treat the humidity-laden air in the aquatic area.

How to calculate the humidity level in the swimming pool room?

What factors should be taken into account to know the evaporation of the swimming pool?

What is the humidity level in my pool room? This is fundamental information to know the quantity of water to evacuate and correctly size the dehumidifier. And to do this it is necessary to determine certain parameters.

- The surface: S, in m² of the swimming pool = length x width. The calculation is simple.

- The level of activity in the swimming pool: N, the number of bathers per m².

- The relative hygrometry of the hall: H, it is estimated for an indoor swimming pool between 60 and 70% for optimal comfort and to protect the building from excessive condensation.

- The humidity level in the air at the temperature of water: HA and the humidity rate of the air at the air temperature: TA. These two data can be found on the psychrometric diagram. You must therefore choose the temperature of the air and water that you want for your indoor swimming pool.

The formula to calculate the quantity of water evaporated in liters per hour is S x (( 13+133 N) (HA-H TA) +100 N): 1000

There are calculators on the internet and it is possible to call on a design office or a swimming pool professional for a more reliable approach.

Take into account the heat balance information

The heat balance is very useful for determining the quality of the insulation and the energy needs of the aquatic room according to the characteristics of the swimming pool hall and the pool and the use that will be made of this room and the wishes of the owners. in terms of comfort. The heat balance makes it possible to choose equipment such as heating and with the support of the calculation of evaporation, the choice of dehumidifier takes shape. The devices best match the constraints of the location and the expectations of bathers.

A few tips not to forget

When considering building an indoor swimming pool, or covering your outdoor swimming pool with a shelter, it is preferable to carry out a complete thermal assessment with evaluation of the evaporation of water from this enclosed space. This allows us to have an approach to future energy expenditure, heating, water, the choice of equipment and their characteristics…

These studies carried out downstream, make it possible to play, rectify or modify the parameters such as the temperature of the water, the air, the quality of the insulation, etc. to optimize the comfort and durability of the building.

Simple actions, such as covering your swimming pool with a submerged shutter for example , when not in use allows you to limit heat and water loss, or to leave doors and windows closed when the dehumidifier is in operation.

Thanks to the thermal balance which brings together all the data and the characteristics of the environment and the calculation of the evaporation of water in the swimming pool room, it is possible to be able to choose the best solutions and the right equipment which allows keep a healthy and healthy building, optimal bathing comfort, without forgetting savings on energy and water.

To help you choose the swimming pool dehumidifier that best suits your installation, we must first answer this question: is the thermal balance essential to choose the swimming pool dehumidifier? The answer is yes ! So read our advice on the energy consumption of the swimming pool dehumidifier so as not to opt for an oversized and overly energy-consuming device. Finally, find out in more detail what characteristics to take into account when choosing a swimming pool dehumidifier and and how to refine your choice of swimming pool dehumidifier.
