The graduation project selected topic for hvac design of huainan sports culture center region D, subject requirements according to wait for the whole year weather conditions make the sports building hvac design scheme, design scheme should be combined with engineering local natural geographical environment, function and use characteristics, meet the requirement of energy conservation and environmental protection, and improve the comprehensive sports building indoor air quality, for sports related staff, audience and staff to provide health, application, security, and efficient use of space, at the same time scheme should be in accordance with the requirements of the design specifications and technical measures (including professional design specification, the fire prevention design, energy-saving design and technical measures for design.
This design content mainly including the design of air conditioning cold and heat load calculation, air conditioning cooling and heat sources, air conditioning scheme and system hydraulic calculation, building smoke control and extraction design projects.The stadium by the race site area, the audience area, accessory occupancy and equipment room of three most, through calculation, the total cooling load in summer index is 207.7 W / ㎡.
This topic in huainan sports cultural center building area is 19820 m2, from 16:00 to basketball, badminton, table tennis and volleyball, set at 6744 (including fixed seats, 3072).For game area and scope of the audience area belong to a large space, air conditioning system adopts centralized air system, including game sites are scattered flow air supply, the audience area nozzle air supply;In addition, considering the competition venues for table tennis, badminton match for the requirements of wind speed, air conditioning system USES frequency conversion type.Choice for accessory occupancy and equipment room of air conditioning, designed two sets of air conditioning system solutions: (1) the fan-coil unit plus fresh air system;(2) the VRV multigang unit.
The choice of cold and heat source according to the requirements, not only including the system of themselves but also relating to the project area, price, policy guidance of energy construction, environmental protection, etc.Considering building purposes, various types of water chiller performance and features, facilities (water source, heat source and power supply), energy prices, initial investment and operating management, such as basic conditions, and change the characteristics of the small, winter and summer load of huainan city this project to determine a reasonable integration of direct-fired machine.
Stadium is a very important public buildings, complex function, numerous people, huge losses when a fire breaks out.This stadium a total height of 24 m, belong to the multi-storey building, refer to the "code for fire protection design of buildings" (GBJ16-87) and "code for fire protection of tall buildings" GB50045-95), the key areas are set up the smoke control system, more than 20 m in aisle, more than 100 ㎡ windowless rooms set up mechanical exhaust system.
Through to the engineering design, to deepen the understanding of the professional knowledge of building air conditioning, control of air conditioning air pipe, water pipe selection and layout, skillfully use related drawing skills, grasp the professional field and the basic methods of scientific research, cultivate the ability to work independently to analyze and solve practical problems, for after the graduation engaged in hvac professional work to lay a solid foundation.
