Heath Recovery from Waste Recreational Pools Water of Thermal Baths and Medical Sanatoriums

Abstract

In Slovakia we can find 35 thermal baths and 28 thermal healing sanatoriums that use geothermal or thermal healing water for their operation. After the use of water in these facilities, waste pool water with relatively high temperature is drained out of these facilities. This wastewater has considerable energy potential, which is used in any way. There are number of buildings in the premises of recreational and medical facilities, which are used for various purposes. Whether it is a building used by the staff of the recreational facility or by visitors. We have two options for using the energy potential of wastewater. The first option in the summer is to use waste heat to preheat cold water, which is used together with geothermal water to fill and operate of pools. The second option in the winter is to use waste heat to defrost the sidewalks within the recreational facility or use this heat in the system of active thermal protection of buildings that are part of the complex. The aim of the paper is to present more ways of using the energy potential of waste pool water, which is produced by thermal baths and medical sanatoriums and calculation results of geothermal water volume decreasing.
