If you're thinking about getting a new dehumidifier for your indoor pool room, you have a lot of decisions to make. A dehumidification system is a big investment, so you probably want a system that's energy-efficient to help you save money in the long run. But before you can decide any of that, you'll need to figure out what size you need your new dehumidifier to be.


Indoor pool dehumidifier sizing is crucial. The right system in the wrong size will do very little to control humidity and air quality in your facility.

How to Size a Dehumidifier

When you're calculating the size of the dehumidifier you need for your pool, there are several factors to consider:


1. Size of the Pool Room

As the size of the pool room increases, the amount of air in the room increases as well. Knowing the size of the room can help you figure out how many times the dehumidifier will process the air in the room each hour. If this number is too low, the system won't work properly and the room will still be humid. On the other hand, if it's too high, the air can become uncomfortably dry for your guests.


2. The Pool's Surface Area

This measurement is essential because it helps calculate how much moisture your pool is giving off. The pool's depth is actually irrelevant, as water evaporates directly from the surface. Make sure you know this measurement when you're choosing your indoor pool dehumidifier sizing.


3. The Temperature of the Pool and the Room

Temperature has a major impact on the amount of humidity that needs to be removed from your indoor pool room. The warmer the water in a pool is, the more moisture enters the air as it evaporates. For this reason, dehumidifiers are more efficient in warmer rooms.


Your heating and cooling needs are also a significant factor to consider when you're choosing a dehumidification system for your indoor pool. With the right equipment, an indoor pool dehumidifier can also act as a heater or air conditioner.


4. Average Capacity of the Pool

The more people there are in a pool at a given time, the more humidity will be in the air. The humidity increases for a number of reasons:

  • More people in the pool means a higher surface area and more evaporation.
  • People exhale moisture when they breathe.
  • Swimmers kick up water as they play in the pool.


For this reason, pool ventilation requirements can vary widely based on capacity. School natatorium design guidelines will almost certainly call for different sizing than a quiet indoor pool in a spa.


5. Your Pool's Equipment Room

It's important to keep your swimming pool's mechanical room design in mind as you choose a dehumidifier. If you choose a system that doesn't fit into your equipment room, you won't be able to use it without making further adjustments.


Be sure to consider the size and control capabilities of your pool's equipment room.
