Stadium as a functional persity of large public buildings, with use of different equipment and different indoor space.Different sports, is also each are not identical to the requirement of inner chamber, thermal environment, such as badminton and ping pong balls projects, for the venue of the wind speed has a very high requirements, on the one hand, because the venue (also including multi-functional conference hall) closed requirements and heat release huge stadium lighting equipment, etc. The objective existence of these conditions.Athletes and the audience, on the other hand, also need a suitable temperature and humidity of the indoor environment for the game and watching, so the venue the pros and cons of indoor thermal environment quality has become the evaluation of the building indoor environment index of important reference basis.In addition, because the largest number of venues, so also nots allow to ignore to the indoor air quality, the new air volume, temperature, humidity and so on these factors on the sports venues of the health of athletes and spectators, safe and have a major impact.
Sports culture center is located in Tian Guan of huainan city district of huainan city, north near chaoyang west road, north road west along the square.Sports cultural center from 16:00 of huainan city construction area of 19820 m2, the venue 46.8 m by 72 m, mainly for a variety of ball games, set at 6744 (including fixed seat 3072);Main building as the framework of three layers, partial set underground, building height of 29.2 m.
The graduation design topic for huainan selected sports culture center B area hvac engineering design, main purpose is to integrate theory with practice, improve practice ability and the ability to solve the problem.Design of cold and heat source for the entire air conditioning system the source of the "blood" and later the size of the medium for the actual runtime provide corresponding guarantee.
The early stage of the design the gym room air conditioning, the audience sat down, and the air conditioning cooling load in the playground statistical computing, and then focus on the hot and cold source of air conditioning system design, the need to consider the working condition of air conditioning cold and heat two, after comparing options, cold and heat source scheme selection for the integration of direct-fired machine finally, for summer, winter two season respectively with necessary refrigerant and heat transfer.
This design including air conditioning system cooling load calculation, water system, the most disadvantaged loop hydraulic calculation and airconditioning pump design of chilled water pump selection and cooling water pump selection), cold and heat sources, room layout design (selection of unit selection, cooling tower), and provide the corresponding design drawings.
