The general illustrate of design
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 Dongwan Jindian hotel 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 Jindian building hotel is located in dongguan city, the building use function is given priority to with hotels, the building has seven layers. Interior design requirements: summer: dry bulb temperature is 26 degrees, relative humidity of 50% to 65%; Winter, dry bulb temperature is 18 degrees, relative humidity greater than 30%. Every guest room all built-in toilet, wash basin, seated toilets and showers. The air conditioning design is mainly aimed at guest room air conditioning system design
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 Wuhan Yang shop for specific types of hotel design are as follows:
⑴    load calculation (mainly carried out gradually when the cooling load)
⑵ air-conditioning system design wind: based on the actual situation of choice for the construction of the system
⑶ cold and heat source equipment design (including the chiller, oil-fired boiler, cooling water pumps, water pumps frozen the design selection, watershed, water catchment design, location and identification equipment installation and pipe layout)
⑷ the calculation of air-conditioning Selection: including the choice of fan coil, air conditioning units and air units of the new calculation Selection
⑸ 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
Hotel with accommodation function is given priority to, combined with the actual situation by adopt fan-coil unit plus fresh air air conditioning system. 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.
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. 七层酒店客房中央空调系统设计+CAD图纸(2):http://www.youerw.com/gongcheng/lunwen_1747.html
