Comparison of heat recovery systems in public indoor swimming pools

The heating of swimming pools can be expensive in terms of energy costs and energy-saving measures which are much more effective than the simple recovery of the exhausted air are recommended. A new open-cycle absorption system is presented here, operating by chemical dehumidification on the exhausted air. It allows important energy savings of the same order as the motor-driven heat pump systems, although its technology is in principle simpler and cheaper.
