The article discusses the design of the system with heat recovery to be used for the ventilation/air conditioning of a swimming pool building, in which air reaches high temperatures and humidities. The systems described and analysed use heat recovery through air to air heat exchanger or heat recovery through heat exchanger and heat pump.
States that various gas techniques seem to be technically and economically of interest to ensure the heating of swimming pools: condensation heaters, the production of instant ECS, low temperature heated flooring, etc. Equally, cogeneration offers wide possibilities. The article gives an introductory note on each of these technologies.
States that air humidity in swimming pools must be closely controlled on the one hand for user comfort, and on the other for the durability of the building structure. Describes how the INSEP pool in Paris has opted for a partial thermodynamic dehumidification system. Finds that although the condensate levels were higher than recommended at time of measuring, this pool nevertheless showed satisfactory results in terms of energy consumption and costs. Also found that the heat demand of the pool compared favourably with an ordinary sports hall in relation to outdoor temperatures.
Discusses how the design of modern swimming pool leisure complexes must adapt to the diverse demands of today's users. States that the air treatment in a covered swimming pool complex depends on a fragile balance between the demands of occupant comfort and the technical imperatives for the conservation of the building structure. It is also of utmost importance to pay particular attention to precisely quantifying the thermal needs, defining the air flow and thermal means of operation, and selecting a principle for dehumidification which is well-tuned to its application.
In discussion with the person in charge of provision for the many swimming pools in the Paris region, both municipal and school, the article gives and overview of the problems to be tackled in terms of dehumidification.
Airflow pattern in an indoor sports hall of 17,325 m3 located in the sports complex of City University of Hong Kong has been investigated by computational fluid dynamics technique. The turbulence flow was taken into account by using Renormalisation Group method (RNG) k-e model. The objectives of this study are to obtain a preliminary understanding of the airflow pattern and evaluate the badminton 'playing zone' within which there should be no disturbance to the badminton shuttle behaviour.
Measurement data and analysis of air distribution in one gymnasium is presented in which the airflow is isothermal. The region considered includes both workaround and non-workaround, which can describe the airflow pattern of this gymnasium correctly. Based on measured data, the airflow pattern of the HVAC system is analysed. And the characteristic of airflow pattern in this kind of large space is summed up. Then some conclusions are drawn as a guide for airflow pattern designing in large space of the similar type.
