Ground-source Heat Pump Central Air Conditioning System Design for the Resort in Nanjing City
Abstract: The graduation project designs a ground-source heat pump central air conditioning system design for the resort in Nanjing city. Compared with traditional air conditioning system, it has a great advantage in energy conservation. It contains: cooling load calculation; the estimation of system zoning; the selection of refrigeration units; the selection of air conditioning equipment; the design of air duct system and calculation; the estimation of air distribution method and the selection of relevant equipment; the selection of ground heat exchanger; the design of water system and its resistance analysis; the insulation of air duct plant and chilled water pipes; noise and vibration control; etc. According to some correlation standard, allow for energy safe and indoor comfort, the air condition system of the design is Fan coil units (FCUs)--fresh air system.
Keywords: The resort; Ground source heat pump; traditional air conditioning system; Ground heat exchanger; Ground source heat pump air conditioning system
