The Design of Ground-source Heat Pump Central Air Conditioning System for a Villa in Hangzhou City
Abstract: The graduation project is the subject of the ground-source heat pump central air conditioning system design for a villa in Hangzhou city. In terms of energy saving, ground source heat pump air conditioning energy saving than traditional more than 30%. 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. This design is based on the relevant norms, to meet the energy saving and comfort requirements, with fresh air fan coil scheme.
Keywords: Villa; Ground source heat pump central air conditioning system; Cold and hot load; Ground heat exchanger
