HFC-134A GEOTHERMAL HEAT PUMPS HELP REDUCING ENERGY CONSUMPTION AT A FRENCH SWIMMING POOL BY A FACTOR OF FIVE

02.10.2016

For the renovation of the the oldest Strasbourg (France) swimming pool heating system, an old gas boiler has been replaced by 2 HFC-134a geothermal heat pumps, delivering each 558 kW heating and 482 kW cooling.

Within one year functioning, the energy consumption for the swimming pool and its adjacent buildings has been divided by five.Underground water at 14-15 C is used as cold source for the heat pumps, which deliver warm water at 28 C to the 2,200 m3 swimming pool. In addition, cooled water from the cold side is reheated before returning to the underground to dehumidify the incoming air supplied to the swimming pool.
