Shops, office, etc in the design of little space can take advantage of the fan-coil unit plus fresh air system, adjusting the air temperature can be different according to different space requirements. Internal area larger more large space can be used in a full air system, management simple, transition season energy saving effect is good.
2.2 The designing principle of wind pipeline system
The pision of air adjustment system should take the flexibility and economic of operation and adjustment into account. The pision of multi-storey buildings’ systems should be depend on the plain arrangement of every storey and the location of engine room, try to arrange the wind pipeline reasonable, make the system operation flexible and economic; the scale of air adjustment system should not be too large, in order to adjust conveniently and reduce noise. In order to regulate and reduce noise. And to cooperate with civil construction unit, completes the duct embedded, shall not affect the civil construction structure.
2.3 The designing principle of water pipeline system
It is required to keep the balance of waterpower, prevent from the large flow and small temperature difference, standard water transport coefficient, adopt convertible adjustment of variable flow system, deal with the inflation and vent of the water system, solve the dispose and filter of the water, and prevent the freezing and keep warm of the pipeline.
