上海大厦暖通空调工程设计计算书+CAD图纸(2)
1 The source of the design
HVAC design is mainly for indoor thermal environment, air quality in design, but construction must be fully aware of the requirements for HVAC and HVAC systems and equipment for construction and other facilities on the basis of design.
The design task is to complete the Shanghai Yibo building conditioning design, design issues since the actual project. Purpose of this project through the design, control air-conditioning systems design, design steps to train students of the problem, solve the problem of the actual application capacity; deepen their understanding of building air-conditioning engineering expertise and understanding of memory; have air-conditioning duct, plumbing , Equipment selection and layout; master of wind and water mains in calculation; enhanced graphics capabilities and develop analytical, problem-solving practical engineering capabilities for the future in the indoor environment and public works construction equipment of HVAC design and construction organizations , Operation and management work for a reliable basis.
2 The general situation of the engineering
The building is located in Shanghai, is a 10-story budget building, the building area of 7800 square meters. Including underground and ground ten layers. Mainly for warehouse and equipment room, the underground layer one to three layers of dining-room, balcony, such as occupancy, four to nine layers for hotel rooms, building height is 36.6 meters. The air conditioning design mainly for air conditioning room above the ground for the design of air conditioning system.The air-conditioning design is mainly directed against above the ground.
3 The basic of Design
3.1 Design task request and the original information
According to the Building nature, purpose and requirements of the construction unit of the Shanghai Yibo building for specific types of building design are as follows：
- load calculation (mainly carried out gradually when the cooling load)
⑶ the calculation of air-conditioning Selection: including the choice of fan coil, air conditioning units and air units of the new calculation Selection
⑷ air conditioning water systems and wind systems design and calculation: including water piping system design, fan coil units and air-conditioning layout
4 The main design work
Choice of architectural features of air-conditioning; cold and heat load calculation; wind of a water pipe layout, hydraulic calculation; breakdown of the water pipeline computation. Hydraulic calculation based on choice of air-conditioning, including air conditioning units, the new wind generating units, fan coil, outlet and other equipment
5 Air condition breeze systems
1 floor to 10 floor are all adopted the new Canadian Wind fan coil air-conditioning systems. As a result of these air-conditioned rooms more, the corresponding area of smaller, separate rooms require adjustment, and the room temperature and humidity requirements do not strictly, have adopted the new Canadian Wind fan coil air-conditioning systems. 4 to 9 layers of standard room according to some area of the control unit, set up for the backwater circuit in order to repair and maintenance.
The new wind-based system, an independent supply of indoor and outdoor weather can change with the adjustment, which is the new wind to deal with indoor parameters, do not assume room load to ensure that indoor humidity and Xinfeng Liang requirements. This programme is improving the system of regulation and the flexibility of operation, and the fan-coil into the water supply can be appropriately raise the temperature, water mains condensation phenomenon can be improved.
