HVAC system energy optimization in indoor swimming pools

Eliseu Ribeiro, Humberto Jorge, Divo Quintela

Abstract: Buildings with indoor swimming pools are recognised as a very high energy consumers, and presents a grate potential for energy savings. The management of indoor ambient conditions must act upon the most sensible parameters that affect the energy consumption. The energy is spent in several ways: 🡪 evaporation heat loss from the pool; 🡪 room temperature very high, typically 28ºC to 30ºC, to maintain the comfort of users and reduce the risk of condensation; 🡪 high rates of ventilation required, usually 4 to 10 air changes per hour, necessary to remove the excess humidity due to evaporation and indoor air quality guarantee. Control Strategies adapted to the reality of each building is an important way to reduce energy consumption. This paper presents control strategies, that can be implemented in the building automation system and the HVAC system of an existing indoor swimming pool complex, in order to minimise energy consumption. In the present case study, an appropriate control strategy, joint with pool cover at night, is a measure for the rational use of energy, that can lead to the reduction of 90 tep/year, which represents about 30.000€ in reduction in energy cost.
