In all pools locat­ed indoors, there is an exces­sive lev­el of humid­i­ty. First, it appears as con­den­sa­tion on the walls, then as mold. And then it spoils fur­ni­ture, equip­ment, dec­o­ra­tion and neg­a­tive­ly affects peo­ple’s health.

You can solve this prob­lem in 3 ways:

The first option is inef­fec­tive, since sil­i­ca gel is dis­pos­able, and you need to con­stant­ly buy new ones. And it will be cost­ly finan­cial­ly.

There­fore, there are 2 ways to deal with excess mois­ture in the pool: instal­la­tion of heat­ing sys­tems and ven­ti­la­tion sys­tems.

Designing a ventilation system in a swimming pool

Design­ing a ven­ti­la­tion sys­tem for a swim­ming pool requires a spe­cial approach. In this case, it is nec­es­sary to take into account the require­ments for:

  • air tem­per­a­ture;
  • air humid­i­ty;
  • air exchange.

After all, this is the only way to orga­nize a com­pe­tent ven­ti­la­tion sys­tem, pro­vid­ing com­fort­able con­di­tions for employ­ees and vis­i­tors to the pool.

Designing a ventilation system in a swimming pool

Air temperature

The opti­mum air tem­per­a­ture in the pool is 26–30°C. More­over, it should be 2–3 ° C more than the water tem­per­a­ture. Why is that? The fact is that when mois­ture evap­o­rates from the skin, the body los­es more heat. As a result, a per­son feels cold.

Humidity level

The opti­mal lev­el of humid­i­ty in the pool is 40–50%. This is enough to avoid stuffi­ness, dis­com­fort and con­den­sa­tion.

Air exchange

This indi­ca­tor is cal­cu­lat­ed as fol­lows:

  • min­i­mum 80 m³/h per swim­mer in the pool;
  • at least 20 m³/h per per­son in the room.

To reg­u­late it, you need to bal­ance the vol­ume of sup­ply and exhaust air. And addi­tion­al­ly put grat­ings (or design cer­tain schemes).

Additional pool features to consider

Additional pool features to consider

In addi­tion to the above require­ments, when design­ing a ven­ti­la­tion sys­tem, it is nec­es­sary to take into account:

  • dimen­sions of the room in which the pool is locat­ed;
  • dimen­sions of the pool mir­ror;
  • win­dow dimen­sions.

Room dimensions

Dimen­sions are tak­en into account in order to:

  1. Cal­cu­late the like­ly lev­el of air humid­i­ty (the small­er the object, the high­er the humid­i­ty lev­el).
  2. Cal­cu­late the air exchange (in this case, the dimen­sions of the room and the num­ber of peo­ple inside are tak­en into account).

Room dimensions

Pool mirror dimensions

From this para­me­ter direct­ly depends on how much air will evap­o­rate. On aver­age, about 200 g of water evap­o­rates from 1 m² in 1 hour of swim­ming.

But the rapid release of mois­ture often leads to mold on all the fur­ni­ture locat­ed inside. And, pos­si­bly, to cor­ro­sion of the struc­ture of the room.

Window dimensions

If the instal­la­tion of the ven­ti­la­tion sys­tem will be car­ried out in the fin­ished pool, the dimen­sions of the win­dows are addi­tion­al­ly tak­en into account. And at the same time their ther­mal insu­la­tion, because the need for blow­ing win­dows with hot air flow depends on this.

As you know, glass­es with high ther­mal insu­la­tion reduce the like­li­hood of con­den­sa­tion on them. But if oth­ers are used, a more com­plex ven­ti­la­tion sys­tem will have to be designed.

Also, the amount of solar heat that will enter the room depends on the dimen­sions of the win­dows. And, accord­ing­ly, the micro­cli­mate inside (air tem­per­a­ture and mois­ture lev­el).

What ventilation systems are suitable for the pool?

For each pool, an indi­vid­ual project of the ven­ti­la­tion sys­tem is cre­at­ed, tak­ing into account all the fea­tures of the room. Below are the most com­mon options that occur most often.

What ventilation systems are suitable for the pool?

Nabornaya direct flow system

2 sep­a­rate sys­tems are respon­si­ble for the exhaust and air sup­ply. They are assem­bled from dif­fer­ent ele­ments:

The main advan­tage of this solu­tion is the low cost. But the econ­o­my here leaves much to be desired. Plus, the heat­ed air flow is removed from the room direct­ly into the atmos­phere.

Nabornaya system with recovery

This solu­tion is sim­i­lar to the pre­vi­ous one. Ven­ti­la­tion sys­tems are also assem­bled from indi­vid­ual ele­ments. But here an ener­gy-sav­ing recu­per­a­tor is addi­tion­al­ly used.

Due to the com­plex­i­ty of automa­tion, such sys­tems are more expen­sive. But thanks to the recu­per­a­tor, they are more eco­nom­i­cal.

Nabornaya direct flow system

Monobloc system

This solu­tion is sup­plied in a sound-insu­lat­ed hous­ing. Even at the fac­to­ry it is equipped with an inte­grat­ed automa­tion sys­tem and a recu­per­a­tor. It is com­pact, which is its main advan­tage.

Supply and exhaust system

Such equip­ment is installed in pools in which water is chlo­ri­nat­ed. Its inter­nal ele­ments have a spe­cial coat­ing that pro­tects against cor­ro­sion.

The air han­dling unit has many advan­tages. But her econ­o­my is lame.

Supply and exhaust system with dehumidifiers

Often in pools a com­bined solu­tion is used. That is, the orga­ni­za­tion of the sup­ply and exhaust ven­ti­la­tion sys­tem + instal­la­tion of air dry­ers. This helps to main­tain an opti­mal micro­cli­mate in the room, and at the same time:

  • extend the ser­vice life of build­ing struc­tures;
  • min­i­mize the like­li­hood of mold and fun­gi;
  • pro­vide com­fort­able con­di­tions for vis­i­tors to the pool.

Supply and exhaust system with dehumidifiers

Also, this solu­tion:

  • min­i­mizes the dimen­sions and solves the prob­lem with the choice of instal­la­tion loca­tion;
  • reduces the cost of equip­ment;
  • reduces oper­at­ing costs dur­ing the oper­a­tion of the sys­tem;
  • min­i­mizes the dimen­sions of the dec­o­ra­tive struc­tures that sew up the air ducts.

This type of ven­ti­la­tion sys­tem pro­vides nor­mal air exchange and a com­fort­able micro­cli­mate. And to remove resid­ual mois­ture, wall-mount­ed dehu­mid­i­fiers are used. This is the main advan­tage of this solu­tion.

This type of ventilation system provides normal air exchange.

The fact is that one ven­ti­la­tion sys­tem does not cope with its work by 100%. Yes, it more or less main­tains an opti­mal micro­cli­mate, but there are things that do not depend on it. For exam­ple, when it rains out­side, air with an increased lev­el of humid­i­ty enters the room. After all, the sup­ply ven­ti­la­tion sys­tem works con­stant­ly, and it is not able to inde­pen­dent­ly make deci­sions about which air to sup­ply and which not.

This is where dehu­mid­i­fiers come in handy. They work in auto­mat­ic mode — i.e. turn on only at the right time. Just in such sit­u­a­tions, when, due to rain on the street, moist air enters the room, dehu­mid­i­fiers instant­ly solve the prob­lem. Of course, pro­vid­ed that they are cor­rect­ly select­ed.

Dehumidifiers are very helpful

Thus, the ven­ti­la­tion sys­tem reg­u­lates air exchange and par­tial­ly reduces the lev­el of humid­i­ty, and dehu­mid­i­fiers help it main­tain this very lev­el of humid­i­ty. In addi­tion, these devices have a mod­ern design, so they look great in any inte­ri­or.

For max­i­mum effi­cien­cy, wall-mount­ed dehu­mid­i­fiers are mount­ed clos­er to the water sur­face. So they will instant­ly remove excess mois­ture. Of course, before this, it is nec­es­sary to solve in advance the prob­lem with the sup­ply of pow­er and the drainage pipeline through which the con­den­sate will be dis­charged.

If desired, you can pur­chase dehu­mid­i­fiers with dif­fer­ent con­fig­u­ra­tions:

  • frame­less devices are great for hid­den instal­la­tion in a false wall or in an adja­cent room;
  • devices with water-cooled con­densers are able to give off excess heat received dur­ing dehu­mid­i­fi­ca­tion, there­by heat­ing the water in the pool;
  • devices with a water or elec­tric heater are able to com­pen­sate for the heat loss of the room.

Also in the pool you can install:

  • sup­ply and exhaust ven­ti­la­tion;
  • duct dehu­mid­i­fiers that can mix out­door air (but this will require an addi­tion­al exhaust sys­tem);
  • duct dehu­mid­i­fiers that sup­port the sup­ply and exhaust of air (they sup­ply out­door air in a much larg­er vol­ume than dehu­mid­i­fiers with admix­ture);
  • sup­ply and exhaust mod­els equipped with an air dehu­mid­i­fi­ca­tion sec­tion.

What is better to choose?

There is no per­fect solu­tion for ven­ti­lat­ing and dehu­mid­i­fy­ing the air in a swim­ming pool. Each option has its pros and cons. And not in terms of effi­cien­cy, but in terms of effi­cien­cy, com­plex­i­ty of instal­la­tion and cost.

There­fore, when choos­ing a sys­tem for ven­ti­la­tion and dehu­mid­i­fi­ca­tion, you must first start from the avail­able bud­get. And already on the basis of this amount, spe­cial­ists will select a solu­tion for you, tak­ing into account all the fea­tures of the pool (area, num­ber of win­dows, aver­age num­ber of peo­ple dur­ing peak hours, etc.).
