This design content mainly includes the air conditioning cooling load calculation, the air conditioning cold heat source design, the air conditioning plan determination and the system hydraulic calculation, the building smoke exhaust design and so on. This stadium is composed of game district, District of the audience, affiliated with room and equipment room three main parts, through calculation, summer cooling load index is 207.7W/㎡.
Because the area of the game and the audience belong to a large space, the air conditioning system adopts centralized air system, and the competition area adopts the air flow fan, the audience seat area adopts the nozzle air supply; in addition, taking into account the competition venue table tennis, badminton game when the wind speed requirements, air conditioning system using frequency conversion. Two sets of air conditioning systems are designed for the air conditioning system of the auxiliary room and the equipment： (1) the air blower coil unit and the fresh air system; (2) VRV multi unit.
The choice of the heat source is not only the system itself, but also the energy structure, price, policy oriented, environment protection and so on. Considering the use of buildings, all kinds of cold water aircrew performance and characteristics, facilities (water, heat and power), energy prices, initial investment, operation management fees, and summer and winter load changes micro characteristics of Huainan City , the project determine the integration of direct fired machine is more reasonable.
Gymnasium is a very important public building, the function is complex, numerous personnel, once the fire loss is huge. The stadium with a total height of 24m, belongs to the multi-storey buildings, refer to the "code for fire protection design of buildings" (GBJ16-87) and the "senior civil building code for fire protection (GB50045-95), the key areas are set smoke control system, more than 20m in the aisle, more than 100 square meters of room without windows which are arranged mechanical smoke exhaust system.
Through the design of the project, deepen understanding of building air-conditioning professional knowledge, master air duct, the selection and the layout of the pipe, proficiency in the use of relative drawing skills, understand the basic methods of scientific research in the professional field, culture independent analysis of issues, solving practical problems ability, after graduation engaged in HVAC professional work to lay a solid foundation.
