4The main work of designs

The main design content is based on the climate characteristics of Shanghai region to give priority to the design of winter heating demand. The original data and the calculation of the parameters analyzed this design of buildings and property of the load calculation, calculation results show that the new air-cooled heat gain load and isolation account for more than half of the total cooling load; doors envelope through the winter heat and cold air infiltration formation accounted for most of the heat load ratio. After comparing system demonstration program, from an economic as well as construction and other aspects to consider, we finally choose combing the ultimately select multi -line air conditioning system and the new system.

The design for the air conditioning duct system pipes hydraulic calculations, as well as indoor fresh air calculation. Choosing multi-line system indoor unit and outdoor unit, fresh air system, fans, etc. And the pipe diameter is calculated to determine the resistance and pipe diameter. Draws the air-conditioning system plan, the water system plan, has written the construction specification.

5 air-conditioning system selecting

The fan coil unit air conditioning system mode of fresh air supply by the independent fresh air supply system of indoor fresh air. After the treatment of fresh air from the air inlet total wind pipe through a branch pipe into each room, separate set of fresh air handling units, adjusted with the change of outdoor air state parameters and ensure the stability of the parameters of indoor air and room air throughout the year can be guaranteed.

Fan coil unit plus fresh air system has the following advantages:

1) The room can be independent of the temperature adjustment, equipment, high degree of localization, less investment. The design technique is relatively simple (and hence the design risk is not large)

2) Flexible arrangement, each room can adjust room temperature independently, when the room is not easy to turn off the unit (off the fan), does not affect other rooms, so as to save operating costs than other systems.
