HVAC design for passive house technology experience center in Sino-German Ecopark

Presents the general situation of the project and its heating ventilation and air conditioning system design, including the design parameters, cooling and heating loads, cold and heat sources, air conditioning water system, air conditioning and ventilation system, smoke control and extraction systems and automatic control system. Depending on the different temperature requirements of chilled water for outdoor air handling unit and chilled beam, selects different ground-source heat pump units. Adopts a two-stage total heat recovery outdoor air handling unit to supply outdoor air. In view of architecture characteristics of the buildings, selects various air distribution modes for spaces according to their heights, swirl diffusers in the lecture hall and jet nozzles in the entrance hall. Optimizes the air flow distribution of the whole building, and summaries some experiences and lessons for the design.
