Title HVAC engineering design of a hotel building in Nanjing
Abstract :It is an HVAC engineering design of a hotel building in Nanjing.The main contents include air conditioning load calculation, air conditioning mode determination, the design of air conditioning system, heating and cooling system design, the design of air conditioning water system and necessary anti smoke exhaust design. This paper introduces the calculation process of air conditioning load, and the load size of every room. The air volume and cold quantity calculation of the whole air system and air water system were separately calculated. The chilled water unit and hot water boiler system was designed and calculated, and the cooling tower auxiliary cooling measures were taken into account. And the staircase and garage are designed to prevent smoke.
Keywords Load calculation Air conditioning system Cold and heat source Smoke control
