Comparison of Economic Indicators of Schemes of Supply Air Handling for Covered Aqua Park

The purpose of the article is to compare the cumulative discounted costs of air drying in the bath hall of the Aqua Park with three modes of the use of supply air dryers as part of air conditioning units. Three configurations of installations are considered: with a water air cooler as a desiccant; with a heat pump as a desiccant and a unit in which for drying the supply air during the working time for the aqua park, the heat pump works only in the warm period of the year. In non-working hours the heat pump is involved all year-round. The cumulative discounted costs for all three options are calculated. For the hall with swimming baths of the covered aqua park, the application of a heat pump for supply air drying is economically feasible compared to a surface air cooler if in the working time, the heat pump is only used during the warm season and during the non-working hours throughout the year.
