Numerical Analysis of the Energy Consumption of Ventilation Processes in the School Swimming Pool

Abstract

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.

Thinking of Green, Low Carbon, and Energy-Saving Designs Based on the Variable Ventilation of Natatoriums: Taking the Jiading Natatorium of Tongji University as an Example

“…The main variables that could affect the effectiveness of opening and closing the swimming pool include solar radiation, external wind conditions, outdoor temperature, and the ratio of opening area to roof area [36]. Among these variables, only the ratio of opening area is directly related to the building itself.…”

Performance and energy optimization of building automation and management systems: Towards smart sustainable carbon-neutral sports facilities

“…The simulation model was utilized to find the servers' optimal layout to reuse the excess heat for pool water heating. In [46], the energy usage of pool ventilation systems was evaluated by examining the effect of reducing the supply air flow rate on the annual energy consumption.…”

“…50% of works using simulation-based optimization targeted planning such as [40,49,53,55,56] investigating the potential of RESs deployment for reduced energy costs, and [45,50,57,59] for system's layout and design. 40% were for operation tasks as in [42,43,46,48] for optimizing the operation of the facility services for reduced energy use. The investigations were conducted by developing simulation model(s) then performing simulation experiments to conclude solutions' feasibility, optimal design options, or control strategies.…”

Heating energy-saving potentials in HVAC system of swimming halls: A review

“…The energy cost in sports facilities generally accounts for approximate 30% of the overall operating and maintenance fees, while that in SHs usually accounts for a much higher proportion [24]. Although SHs are just a very small proportion in building sectors, they do occupy relatively considerable building energy use, and their energy cost accounts for quite large part of overall operating and maintenance fees [25]. However, it seems the energy use level and energy-saving potentials in SHs have not attracted enough attention.…”
