Abstract
Increasingly more leisure facilities, such as water parks or indoor swimming pools are being built in Poland nowadays. In order to ensure the air quality required by standards for such leisure facilities it is necessary to fit them with effectively functioning ventilation. For the removal of excess humidity, as well as chlorine ions occurring as a result of the disinfection of water as well as the carbon dioxide emitted by people using the facility, the ventilation system needs to be appropriately designed and efficient. For this reason, studies into the air quality in such facilities were undertaken. The paper presents the causes and consequences of the inappropriate operation and maintenance of ventilation systems in swimming pools. The study found that the causes of deterioration in the technical condition of the system which was operated in an environment with chlorine ions were: an inappropriate manufacture of its components and the wrong choice of construction materials for the given environment of operation. Furthermore, failure to follow the manufacturer's guidelines for the operation and maintenance of the components of the ventilation system greatly precipitated its degradation and the occurrence of sick building syndrome in the swimming pool. Solutions were found and proposed in order to improve the efficiency of the ventilation system in the given swimming-pool facility.
Highlights
The high relative humidity of air and air pollution in indoor swimming pools mainly result from the water evaporation from swimming pool basins and substances used for its disinfection [1]
Bacteria and fungi growing in such humid conditions may have a significant impact on the health of people staying for a long time in the area
This phenomenon may cause discomfort for people working in these types of recreational facilities and have a significant impact on the degradation of materials used inside swimming pool buildings [2]
Summary
The high relative humidity of air and air pollution in indoor swimming pools mainly result from the water evaporation from swimming pool basins and substances used for its disinfection [1]. To ensure the required air quality standards, it is necessary to use the ventilation system of an indoor swimming pool building [3]. For these facilities, at least three exchanges of the entire volume of indoor air within an hour should be provided. Due to the use of recirculated air, the entire internal surface as well as structural elements and individual components of the control panel are subject to constant contact with aggressive air For this reason, the pool ventilation unit and its internal equipment needs to be properly secured and made of high quality materials resistant to corrosion [4]. In order to analyze the effectiveness of removing excess moisture and pollutants contained in the air in the building of the indoor swimming pool, and to assess the energy efficiency and reliability of the ventilation system, an indoor swimming pool with a 25-meter pool has been chosen as the research facility
