Title  Designing about the air conditioner engineering of one   Hospital that locates in  JiNan。

Abstract This design is about the air conditioner engineering of one Hospital that locates in JiNan。The hospital is pided into A、B、C three area,and the basement is located in the A area。There are fifteen stories above ground of A area, and the gross floor area is about25000 ㎡。B has two stories above ground and the gross floor area is about2000 ㎡。C has five stories above ground and the gross floor area is about5000

㎡。The total gross floor area is about30000 ㎡,and the air-conditioner area is about15547 ㎡。

The total cooling load is 1588。733kW,the cooling load index is 102。2W/㎡。The total heating load is 1990。448kW,the heating load index is 60。6W/㎡。The cold source of comfort air conditioning system selects two water cooled screw type water chiller。 Model is WNS2。1-1。0/95/70-Y(Q),the rated cooling capacity is 860kW。The heat source selects a horizontal gas hot water boiler,model is WNS2。1-1。0/95/70- Y(Q),the rated heat capacity is 2100kW。Air conditioning water system is a closed double-tube system with the same course and is pided into four areas,and A area is pided into 2 systems in the vertical direction。There are three water-chilling pumps, two for using and one for preparing and three water-cooling pumps,two for using and one for preparing,the water-chilling pumps and two hot water pumps,one for using and one for preparing。

According to the actual function of rooms,fan coil unit plus independent new fresh air system and are selected。The fresh air is sent into the room directly after treated to indoor enthalpy value。The airflow organization adopts side sent and ceiling sent of air distribution。

The fire stairs and antechambers are designed with positive pressure mechanical air supply system,toilets are designed with air exhaust system,corridor are designed with the smoke exhaust system。

Keywords Air-conditioning engineer; fan coil; smoke control system; positive pressure mechanical air supply
