Central Air Conditioning System Design For A Complex Building In Fuzhou

Abstract: The graduation project is the design of the central air conditioning system of complex building in Fuzhou。 It mainly meet the requirements of cooling in summer and heating in winter, mean to provide a comfortable working environment and activities environment for the mall and the staff。 The building is characterized by a floor to three layers of shopping malls, four to twelve layers for the office floor, the top mainly for the relaxation room and equipment layout related rooms。 The design content mainly includes: Calculation of cooling load of air conditioning; type selection and layout of air conditioning equipment; design and arrangement of the air system; the selection of centralized air conditioning system；the selection of fresh air units and fan coil units; water systems design and hydraulic calculation; design of condensed water system; selection of expansion tank; pipeline insulation and corrosion protection; noise elimination and shock proof design ；selection of refrigerating unit and pump selection etc。 The design according to the relevant specifications to meet the requirements of comfort and energy saving, use the scheme of fan-coil plus fresh air system in office building，and similarly use the centralized air conditioning in business building。

Keywords: complex building; central air conditioning; calculation of cold and heat load; centralized air conditioning system；fan-coil plus fresh air system
