ᐅ Connecting a Pool Room to a Mechanical Ventilation with Heat Recovery System? Chlorinated Water? Condensation?

jx7Hello everyone!
A question about mechanical ventilation with heat recovery systems:
(1) Is it generally possible to connect a pool room to a mechanical ventilation system with heat recovery (e.g., two exhaust vents in the pool room)?
(The pool is small and covered when not in use).
Detailed questions:
(a) Does the chlorinated water cause any issues?
(b) Does the increased humidity cause any problems? For example, is there a risk of condensation of moist air inside the exhaust ducts? (The pool room and the mechanical ventilation system would be located a few meters (yards) apart on the same floor).
A dehumidifier would be used in the pool room simultaneously (if needed).
I would appreciate expert answers and/or experience from homeowners.

No, it’s not a problem with controlled residential ventilation.
There is no chlorine in the water vapor.
You will definitely need a proper dehumidification system, especially with higher water temperatures.
How do you plan to chlorinate? Organic, inorganic, or bromine...
Filtration technology, etc.? This should be very well planned. Hopefully, you don't use filter cartridges, as then you become a slave to your "pool."

You will absolutely need a proper dehumidification system, especially at higher water temperatures.

So chlorine is not an issue.
But what about condensation in the air ducts from the pool room to the controlled mechanical ventilation system (10m (33 feet) duct length on the same floor)?
Would the airflow capacity of a controlled mechanical ventilation system be sufficient?
Otherwise, we are currently leaning towards a decentralized ventilation system with heat recovery ("bathroom fan").
If we notice that this is not quite enough, then we would add a dehumidifier (which would also slightly warm the room).
The risk of mold is relatively low because the basement is very well insulated (the house is close to KfW-55 standard).
We use UV plus chlorine for water treatment as well as a circulation pump with filter.
Manufacturer: Endless Pools Model "Performance Pool"
Oh dear.
Forget about UV. Automatic dosing of liquid chlorine and pH adjustment?
Automatic backwash for the filter? A reliable pump?
I checked the manufacturer and model. It’s just a basic all-in-one unit. Not ideal when it comes to the filter, control system, and so on.
It will be enough for indoor use. In the worst case, you just need to replace some water. There isn’t much in there anyway.
Forget controlled ventilation or bathroom fans for humidity control.

Update:
The current plan is:
A 235 m3/h (138 cfm) exhaust fan installed in the basement window ("Vortice Vario 150"), which ventilates the 48 m3 (1,695 ft3) of air in 10-15 minutes.
If this does not sufficiently dehumidify, an additional "regular" dehumidifier will be added in the pool room, for example:
Eeese Otto, dehumidifies 20 liters/24h (5.3 gallons/24h), 245 W
In my opinion, a dedicated pool dehumidification system costing 3,000-4,000 euros is only necessary if the pool is used for several hours a day.
I have the following message from the American manufacturer (translated from English).
“Most of our customers use an exhaust fan to control moisture. When the pool is in use and the cover is open, some moisture develops in the room. However, the amount of moisture produced is very low and can easily be removed from the room with a wall-mounted exhaust fan and/or a simple air dehumidifier. The exhaust fan for a typical pool room has a capacity of 170-200 m3/h (100-118 cfm).”
In a video titled “controlling-pool-room-humidity” on the endlesspools homepage, they mention that at a water temperature of 29°C (84°F) and an air temperature of 26.5°C (80°F), about 1 liter (0.26 gallons) of water evaporates after 1 hour of pool use.
I have had email contact with 10 Endless Pool customers who did not use a dehumidifier, and with 6 Endless Pool customers who used an inexpensive dehumidifier costing less than 500 euros, so I hope this plan will work out.
