How are pools organized?

It would seem that the pool is just a large container of water, but everything is much more complicated. It is not a simple system, with dozens of processes going on in parallel. Today we will talk about how a pool is designed, how it is installed and why we need all those obscure things in our catalog.

Types of pools deals with the installation of two types of pools.

Wooden, which is suitable for both indoor and outdoor use. These basins can be installed either above ground or partially embedded in the ground. Swimming pool body is collected from board with special impregnation, and inside it contains the traditional geotextile coating and necessary accessories. Installation of such a pool can be done in 2-3 days;

Frame of polypropylene panels, which are more solid construction. The pool deck is assembled from highly stable polypropylene plates. Installation of a frame pool in the ground will take at least a week. Of course it is faster and cheaper than pouring a concrete pool.

Perhaps to figure out which pool is better than a wooden or panel pool is impossible. You need to assess a number of parameters, such as where you need to install the pool, what design you like more, the required size, waiting time of installation, the allowable level of construction work during installation. So look at the photo and characteristics, and then decide.

  • Concrete pools, which are a solid structure of concrete and specific coatings. This approach has been used more and more rarely recently, thanks to the existence of faster and less energy-intensive alternatives;
  • temporary frame pools that can be installed and disassembled in the flow for, they are less aesthetic and can bring more problems in maintenance, but at the same time, they have a low cost and you can install them yourself.

There are no fundamental differences in equipment for stationary models of pools, so let’s talk a little about what functions perform all the elements of pools.

What the pool installation looks like?

To understand what you need for the full functioning of the pool, it is worth to understand how this system works. The figure below shows a schematic diagram of the pool.

In addition to the main water bed, there are a number of hidden from the human eye components of this system.

The water will constantly move in a closed loop, which consists of a series of steps:

  1. The upper layer of water is taken from the pool through the skimmer, where it is cleaned from large particles of debris – leaves, hair, etc.
  2. The next point in the circuit, where the water enters, is the pool filter unit. Here the liquid is cleaned of particles that cause turbidity, silt, sediments, etc. Also here water is supplied from the bottom drain and downspouts on the pool walls, which can be used for full recirculation of water for enhanced cleaning.
  3. After the filter, the water can be sent back to the pool through the chlorinator, to the sewer or for heating.
  4. The heat pump is designed to heat and cool water by converting air heat. This is an optional component of the system.
  5. After heating, the water passes through the disinfection stage and is sent back to the pool through the nozzle, which is located on the opposite side to the skimmer.

What are pool skimmers?

The list of these elements includes all the components installed in the pool at the stage of installation – lamps, skimmers, a variety of nozzles, drains. The task of these components is the full functioning of circulation, filtration and water heating, as well as some aesthetic nuances.

What is a skimmer for the pool?

This device is the same window that is installed in the wall of the pool at the level of the upper layer of water, where the accumulation of leaves, dirt, hair and other things. Water is sucked into the skimmer, passes through the mesh installed inside it in the form of a small bucket, which captures all large impurities, after which the water is sent through a pipe to the filtration system. To understand how a pool skimmer works, let’s look at its construction.

nozzles drains

Let us describe in detail what are each part.

1 – Filter cover, works on the principle of a bayonet flap. It is needed in order to remove the bucket net from the skimmer and clean it from debris;

2 – Adjustable depth of the skimmer, which allows you to properly install it in the wall of the pool;

back pool

3 – the neck – the opening into which the water enters;

4 – The front panel is responsible for the appearance of the skimmer’s neck;

5 – spillway valve to limit the drainage of water;

6 – attached flange for mounting;

7 – mesh basket – a filter that is installed in the grooves of the skimmer;

8 – side outlet for water;

9 – flow regulator – provides optimal water flow rate to the filter station;

10 – bottom drain;

11 – overflow – protects the system from overpressure in case of a clogged basket and other system malfunctions.

there are also overflow floating skimmers, they are usually used in temporary pools.

Why do not all stationary pools have skimmers?

If you pay attention to the pool and did not see a skimmer window anywhere, then you probably installed an overflow system – at the border of the upper water level there is a kind of groove in the wall, which overflows water. It also collects the surface layer of water with debris and drains into the filtration system. Overflow pools are mostly large concrete sports pools of older construction. Overflow system is made in the process of concreting the pool.

Nozzles for the swimming pool

Pool nozzles and drains are also important parts.

nozzles drains

Nozzles are designed to draw water from the pool and return it back into the pool after cleaning at the filtration plant, as well as to connect the vacuum cleaner and other devices.

How do pool filters work??

The water filtration system of the swimming pool is one of the most important elements for the proper functioning of the entire system. If your pool filter doesn’t work, you’re sure to have increased turbidity, sand on the bottom, and other problems.

Now let’s look at how to filter your pool properly and consider the main question – what is and how does a sand pool filter work.

The device is a cylindrical balloon molded from polypropylene. Inside the cylinder there is a sand filtering material, a pipe that distributes the water in the loading thickness and a second pipe that drains the water from the cylinder.

In essence, the principle of pool water purification is similar to the operation of a conventional mechanical backfill cylinder.

What does the heat pump for the pool?

The water temperature in the pool is one of the determining factors for comfortable swimming. The recommended temperature for swimming pools – 28 – 32 ° C, the water for pools in saunas should have a lower temperature – 4 – 12 ° C. Especially nice to swim in the water at room temperature when it is cold outside. To help in this case comes special equipment for swimming pools.

The principle of operation of heat pumps is based on the fact that to accumulate heat from the environment and transfer it to the water, the heat pump itself does not generate heat. In essence, the pumps work on the principle of a refrigerator or air conditioner, but vice versa.

There is a fan in the housing of the heat pump, you can see it behind a grid on the outside, just like an air conditioner. It draws in air and directs it to the evaporator. The liquid refrigerant enters the evaporator and turns into a gaseous state by taking the heat from the air. Then the heated gas goes to the compressor which increases the temperature of the gas. After that the heated gas is sent to the condenser, where the refrigerant returns to its liquid state and transfers the heat to the pool water, which circulates through the heater.

The chlorinator for the pool

This element in the pool is needed to continuously add chlorine and other reagents to the water. Conventional chlorinators are designed for relatively small pools up to 100 m3. For larger systems, full dosing systems are usually used. As for small pools, they may not use a chlorinator, because the tablets can be placed directly in the skimmer.

And of course you will be interested in another important question.
