Abstract


With the growing importance of the development of sports in China and people healthy , swimming has become one of the favorite sports . Natatorium engineering rationality is particularly important, and in the swimming pool in the engineering design , HVAC design and occupies a very important position . Firstly, in the North China Electric Power University, central air-conditioning system and electric floor radiation heating system temperature radiant floor heating and new wind combination air-conditioning system of the trial study determination of the air-conditioned small room 's temperature field ; followed by the establishment of the air-conditioned small room of the physical model and mathematical model electric radiant floor air conditioning airflow coupling problem solved using numerical simulation method ; and the simulation results are compared with the measured results analysis , to verify the correctness of the model and calculation method for low temperature radiant floor heating and air conditioning systems ( such as the promotion and application of the swimming pool temperature radiant floor heating and air conditioning system) provides a theoretical basis . On the basis of the above experimental verification , a big game with unilateral stands Natatorium as the research object , the edge of the pool area ground using low-temperature radiant floor heating , airflow and comfort for the swimming pool . Carried out the natatorium indoor heating , air conditioning system design , to establish the physical and mathematical models of the swimming pool , the use of CFD simulation software simulation study of four relatively reasonable airflow organization program . Analysis of the relationship between the evaporation rate and air distribution components ( water vapor , chlorine , carbon dioxide) and the condensation prevention measures , and for creating the natatorium indoor comfort environment design countermeasures . In this paper, Fuzzy Analytic Hierarchy Process (Fuzzy Analytic Hierarchy Process, indoor environmental quality FAHP) Evaluation of four air distribution program ; analysis of four scenarios in the case of the four programs of the same volume of fresh air and personnel scattered wet indoor sensible heat to the heat consumption and fan consumption power . Airflow in order to get the best form of organization , to meet the the Natatorium comfort requirements , solve condensation problems , extend the service life of the swimming pool at the same time , improve the quality of the indoor environment . Provide a reliable reference for future big game the natatorium air conditioning system design, operation and management .
