Evaluation of the effectiveness of various ventilation options for a swimming pool

The popularization of sports and a healthy lifestyle in Russia led to the construction and reconstruction of numerous swimming pools in recent years. Moreover, unlike other sports facilities, swimming pools are subject to some of the strictest regulatory requirements for maintaining a given microclimate in rooms with active moisture release. Ventilation systems of these facilities should not only effectively assimilate moisture release, preventing moisture, corrosion and destruction of enclosing structures, but also be both energy efficient and economically profitable. Therefore, the paper highlights the study of various options for the installation of ventilation systems for a swimming pool with a water surface area of 400 m2 as part of a sports and training center in Chelyabinsk, in order to identify the most rational according to the described criteria. It considers the following options of supply and exhaust systems: ventilation with recirculation, ventilation with additional dehumidification, ventilation with recirculation and recovery. It also provides a technical and economic comparison of these systems, determines annual heat consumption and calculates payback periods. The results of the study prove that the traditional ventilation system with recirculation is the most cost-effective one for this facility according to the totality of all the criteria studied. It is distinguished from other options by low capital investments, average operating costs and the shortest payback period.
