The installation of HVAC equipment is a huge project, which is very complicated and different uses.. For example a complete HVAC design to covers of all equipment and pipes in the air terminal equipment, the wind sending pipe, exhaust pipe, chilled water, electrical bridge, condensation water pipe and a spray pipe, fire tube design. If some functions and sizes of pipeline layout, planning unreasonable, there will appear pipeline elevation, positioning cross serious phenomenon, to engineering construction and management to bring great difficulties. Usually in the drawings, unclear meaning hastily construction will cause the first installation of pipeline construction is easy to install, installation construction, so that some pipeline is forced to install in unreasonable position or elevation, seriously affect the engineering quality and progress, in view of the above problems should be integrated design of pipelines.
The air conditioning system design of Furong building located in Shanghai, the building height of 17.7m, building area of 1285 square meters of air conditioning. Building ground floor, ground floor 5, underground one for the equipment, the ground floor of the one or two floors for the hall, the duty room and dormitory, three to five for the dormitory.
The design standards in strict accordance with the relevant standards promulgated by the state as well as the details of the task given in the book, which indoor design of the main parameters as follows:
Hall: summer indoor temperature is 25 degrees Celsius, relative humidity is 60%, the winter indoor temperature is 18 degrees Celsius, relative humidity is 40%, the amount of fresh air is 30m and noise standards around 35-40NC.
Dormitory: summer indoor temperature is 25 degrees Celsius, relative humidity is 60%, the winter indoor temperature is 18 degrees Celsius, relative humidity is 40%, the amount of fresh air is 30m and noise standards around 35-40NC.
Duty room: summer indoor temperature of 25 degrees Celsius, relative humidity is 60%, the winter indoor temperature is 18 degrees Celsius, relative humidity is 40%, the amount of fresh air is 30m and noise standards around 35-40NC.
The main principle of this design is energy saving economy.. Shanghai lotus building is mainly used for dormitory, so air conditioning design is no need to be too accurate, designed to comfort and easy economy can.
Shanghai lotus building is a comprehensive building, it contains the hall, the duty room and dormitory. According to the meteorological conditions of Shanghai, and the air conditioning design, the basic scheme of the design was set up.. Uses the design of fan coil unit plus fresh air semi central air conditioning system, the centralized system applicable room area is big but the wind pipe is not easy to layout; multi room storey low, heat and moisture load is not consistent or parameters require different; request the indoor air not collusion, adjustable air volume. Of a semi centralized system flexibility, good energy-saving effect, can adjust itself according to the load on the indoor coil in winter and summer dual-purpose. System cooling load by the screw type water chiller supply, heating supply by regional boiler room room does not need also for cold and heat, so the selection of closed two pipe system, cold water and the hot water in common use a pipeline, has the advantages of simple system, the need to overcome the hydrostatic pressure, water pump pressure and power were low, the initial investment is low. The arrangement of dry pipe adopts horizontal type pipe, the choice of different programs, the first grade pump and the pump variable flow system.
