Swimming pool technology
Air-conditioning

Switch off after the stress of daily life, let your mind wander, and have fun. And the best place to do this is on the water - with a pleasant climate.

Whether in their own indoor pool, in a hotel or in public pools and wellness areas, more and more people are fulfilling this desire. And at the same time they contribute to their health, fitness and well-being.

To feel really good, however, it does not suffice to have well-tempered and well-treated water at disposal because also the room climate is crucial.

Humidity increases in the course of the water evaporation. The sultry limit is quickly exceeded. This results in the creation of an uncomfortable climate, which puts a strain on the circulation. Odour substances released into the air from the surface of the water can also pollute the organism. Consequently, a constant air exchange and the supply of the hall with fresh outside air is essential for an uninterrupted bathing experience.

In addition to the health aspect, when planning swimming pools, you have to consider the effect of humidity on the building fabric. The water vapour bound in the air diffuses through plaster and masonry and condenses in the outer wall as soon as the temperature drops below the dew point. This results in a considerable structural damage. This is why, in addition to structural measures - such as for example the installation of a vapour barrier and of a good thermal insulation - a regulated indoor climate is essential.

The conditioning systems manufactured by tecair air provide the necessary air treatment and a natural climate in indoor swimming pools and wellness areas. All dehumidifying, ventilating and heating devices are integrated in one device.

Thanks to the intelligent control, the devices work automatically in the background. And depending on the outside and indoor climate this always happens in the most economical mode of operation

When dehumidifying indoor swimming pools, you profit from the fact that the cold air binds less moisture than the warm air. In this context, it should be noted that the energy content of the warm and humid indoor swimming pool air is very elevated. This is why, when selecting a suitable dehumidifier, it is essential to ensure that this energy is not lost in the course of the dehumidification process.
In practice, the indoor swimming pool air is dehumidified by using the method listed here in the following:

Thanks to this dehumidification method, the hall air is sucked in by a fan and fed through the evaporator of a closed cooling circuit. Similar to the refrigerator, the air is cooled at the evaporator until it falls below the level of the dew point and the moisture is excreted. In the evaporator the thermal energy is transferred to the refrigerant. Then it is brought to a higher temperature level by means of a compressor. In the condenser, this energy will be transferred back to the now drier indoor air. Optionally, outside air can be added in order to achieve an improvement of the air quality

In this context, the hall air is extracted by means of an exhaust fan, passed through an air-to-air heat exchanger (recuperator). After that, it is taken outside. With a supply air fan, dry outside air is sucked in and filtered. After that, it is fed through the recuperator. The thermal energy of the hall air is transferred to the outside air in the recuperator without mixing the air flows.

As with the simple recuperator principle, the energy in the hall air is transferred through the recuperator. To achieve the efficiency-increase of the recuperator and to significantly reduce the consumption of electrical energy, the amount of air is regulated steplessly depending on the requirement. The halving of the air amount results in a power consumption reduction by approximately 85%.

At this stage, the advantages of the stepless recuperator principle and those of the heat pump principle will be combined by means of a high-quality control system in order to achieve the creation of a highly efficient system. The excess heat which often occurs in heat pump systems may optionally be transferred to the pool water through an additional heat exchanger.

A smart control is a prerequisite for an optimised system in terms of economy and comfort.
This cannot be achieved with standard solutions, in particular in the swimming pool and wellness area, the interaction of the different parameters is too complex.
For this reason, the control systems we use have been specially developed for the air conditioning in indoor swimming pools.
The control is adapted to the system requirements and not vice versa. All control systems, including the software, are developed, manufactured and programmed in-house. This means that we are able to respond flexibly and quickly to customer requests at any time. Our experience of more than three decades is also reflected in the continuously developed and optimised software. The range of our control systems goes from the simple compact device to the complex large-scale plant.

Of course, the remote control and the monitoring by using a tablet PC and/or a smartphone will also be feasible in conjunction with the control UNICON C.
