A green solution from Cegelec Perpignan
The Angléo Balnéo & Spa, located in the village of Les Angles at the heart of the Western Pyrenees (France), appointed Cegelec Perpignan to solve the problem of excessive energy consumption in supplying its pools. The spa uses an adduction system to obtain its water, which is extremely cold due to the 1,800-metre altitude.
Heating this water to between 4 °C and 10 °C (the average temperature across France) consumes a great deal of energy.
To resolve this problem, Cegelec Perpignan and BET EnergieR designed and implemented a solution to reduce as far as possible the energy required to heat the water. Grey water from pool overflows and partial draining is no longer discharged directly into the sewer system, but is recovered and channelled into a thermodynamic system with an exchanger, where its residual energy is captured and used to heat the fresh water supply.
This virtuous solution helps reduce the energy impact by preheating the water for refilling without the need for an additional energy source.
It is estimated that the system will provide energy savings of around 288 MWh and avoid 13 tonnes of CO2 emissions every year!
