Air conditioning and ventilating design of the Zhongcheng Saite Shopping Centre

There are two centrifugal and one screw chiller units used for cold sources of the emporium. In the water system primary pumping is adopted, with vertically reversed return piping mode and horizontally direct return piping mode. To solve the problem stemmed from the insufficient ceiling height for the air conditioning system, makes use of the auxiliary space in the building to place air conditioning unit. Installs air handling units on separate floors and in several zones. Selects coils with more rows to increase enthalpy difference and ratio of refrigerating capacity to supply air volume, and decrease space occupied. Outlines the design of air conditioning, ventilating and smoke exhaust, and the operating effects. Summarizes the design experience.
