“…Nevertheless, other studies have shown that, in general, CFD simulation and in particular the chosen turbulence model is capable of reproducing air flow patterns in swimming pools or other large spaces buildings with satisfactory results [27,29,30]. This work documents a CFD methodology to assess ventilation in large swimming pool halls while considering small-scale diffuser geometry with low computational resources.…”

“…For example, airflow, thermal comfort and/or indoor air quality has been evaluated for swimming pools [24,25] or an ice rink arena [26]. The experimental validation of CFD models of large indoor spaces has been documented on various occasions [27][28][29][30]. CFD methods have also been used to calculate the evaporation rate in indoor swimming pools [31,32].…”

The operation of a typical indoor swimming pool is very energy intensive. Previous studies have shown that high quality thermal building envelopes, i.e., with high levels of insulation and airtightness, make it possible to rethink conventional ventilation concepts. Due to the reduced condensation risk in and on envelopes of high thermal quality, ventilation design can be optimized for indoor air quality rather than for averting condensation on the facade. This work investigates different air distribution concepts for an existing swimming pool via computational fluid dynamics (CFD) simulations to evaluate their ventilation efficiency. To reduce modelling and computational resources, the velocity and turbulence fields produced by the swirl-diffusers are determined in a set of separate CFD simulations and incorporated into the swimming pool models. The results show that the ventilation efficiency in the examined swimming pool could potentially be improved with various alternative air distribution concepts, therefore improving the indoor air quality. Although the results seem plausible and compare well with the limited measurement data of air humidity, a more formal experimental validation is still needed before generalizing recommendations.

“…To calculate the moisture emission from the pool water surface, the calculation formula (2) was used, in accordance with the guidelines [6]. The selection of this calculation method was made on the basis of previous research [29], in which six different methods of calculating moisture emission from the pool water surface were analysed. Moisture emission from the pool water surface was calculated according to the formula [6]:…”

Ventilation of an indoor swimming pool is a very energy consuming process. This is a result of, among other things the required high value of the ventilation air volume flow rate, calculated on the basis of the moisture gains in the facility. The total energy consumption consists of the heat required to heat this air and the electricity needed to transport it. It is possible to reduce the ventilation air volume flow rate by assuming the correct value of specific humidity of the supply and indoor air, but then a deterioration of thermal-moisture conditions in the building can be expected. The aim of this paper was to examine how the reduction of the supply air volume flow rate affects the energy consumption for indoor swimming pool ventilation. It was also checked how this consumption can be reduced by using two-stage heat recovery in the air handling unit. Multi-variant simulations of energy consumption for indoor swimming pool ventilation were carried out using the IDA ICE software for day and night operation of the swimming pool throughout the year. The results of the research proved that reduction of the supply air volume flow rate resulted in the lower energy expenditure on ventilation. The variant with additional local air supply to the lifeguard zone was also analysed, which caused only a slight increase in energy demand for ventilation.

A large amount of heat is needed to maintain the thermal comfort of both indoor and outdoor swimming pools in cold seasons. This motivates the development of various heating technologies aiming to reduce energy use, as well as operating and investment costs. Although their development can be traced back to the 1960s, a comprehensive review of these technologies is lacking. Therefore, this paper presents a comprehensive review of the development of heating technologies for swimming pools. This review firstly introduces available heat transfer models that can be used to calculate or predict heat loss and heat gain for swimming pools. Then, different passive and active technologies are summarized. The active heating technologies used for indoor swimming pools include solar collector, heat pump, waste heat recovery, geothermal energy, and congregation technologies. The active heating technologies used for outdoor swimming pools include solar collector, heat pump, PCM storage, geothermal energy, biomass heater, and waste heat recovery technologies. A discussion is presented on the practical and possible heating techniques for swimming pool applications. Finally, through the reviewed literature, future research opportunities are identified, to guide researchers to investigate swimming pool heating systems with suitable and relevant technologies.
