For the design of an air conditioning system, a scheme must be behind the feasible basis, so the discussion and argument is a link in the design essential. According to the basic parameters of the project and some practical circumstances, mainly is the comprehensive square dominated by the commercial, so here the norms and standards are built on the basis of this important principle.
Design of indoor temperature and humidity parameters based on energy principle, according to the space use by HVAC design specifications and design manual selection.
The building is located in Shanghai City, for the design of air conditioning system in Shanghai comprehensive building, a total construction area of 4863 square meters. The one or two layer is the office building, four or five layer three layer show room, central control room, exhibition hall, etc..
Combined with the actual situation of the housing, 1 ~ 2 layer due to meet the small room, each room on indoor environmental requirements are different, so the use of fan coil system, 3 ~ 5 layer, because the room area and compliance are larger, adopt the whole air primary return air system. The detailed design of the system scheme and the system cooling load calculation, air quantity calculation, equipment selection, air system, water system hydraulic calculation and system arrangement. The requirements of the design and the original data
Design task request and the original information
According to the Building nature, purpose and requirements of the construction unit of Comprehensive building for specific types of hotel design are as follows:
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, 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
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
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.
As the building's air conditioning system using water-pressure gas tank closure expansion tank means constant pressure. Taking into account the simple design of the pipe line system, the design of water systems in a dual-tube. Rooms vary for the horizontal part of program, namely for, the backwater stem the flow of the opposite direction, each Yi Huanlu ranging from the length of the pipeline, without the return by the way, tubes shorter length, the pipeline simple vertical for the same Program, that is, that is, for, backwater stem the flow in the direction of the same, after each Yi Huanlu the same length of pipe, use of the way so that water distribution, regulation of convenient.
