Mathematical modelling and simulation of the thermal performance of a solar heated indoor swimming pool
Buildings with indoor swimming pools have a large energy footprint. The source of major energy loss is the swimming pool hall where air humidity is increased by evaporation from the pool water surface. This increases energy consumption for heating and ventilation of the pool hall, fresh wat...

description |
Buildings with indoor swimming pools have a large energy footprint. The
source of major energy loss is the swimming pool hall where air humidity is
increased by evaporation from the pool water surface. This increases energy
consumption for heating and ventilation of the pool hall, fresh water supply
loss and heat demand for pool water heating. In this paper, a mathematical
model of the swimming pool was made to assess energy demands of an indoor
swimming pool building. The mathematical model of the swimming pool is used
with the created multi-zone building model in TRNSYS software to determine
pool hall energy demand and pool losses. Energy loss for pool water and pool
hall heating and ventilation are analyzed for different target pool water and
air temperatures. The simulation showed that pool water heating accounts for
around 22%, whereas heating and ventilation of the pool hall for around 60%
of the total pool hall heat demand. With a change of preset controller air
and water temperatures in simulations, evaporation loss was in the range
46-54% of the total pool losses. A solar thermal sanitary hot water system
was modelled and simulated to analyze it's potential for energy savings of
the presented demand side model. The simulation showed that up to 87% of
water heating demands could be met by the solar thermal system, while
avoiding stagnation. [Projekat Ministarstva nauke Republike Srbije, br. III
