II Abstract

It is a central air-conditioning design for a office building in JiNan City.The building

covers an area of about 15333.3 square meters, with a building area of about

34087.68square meters and with a air-conditioned area of about 12250.38 square meters.

The cooling load is 1073.65 kW,while cooling index is130W/m2. For the 178.747 kW heat

load, heat index is 20 W/m2. According to the building’s functional requirements

application characteristics,I analyzed and compared a variety of air-conditioning modes and

chose the fan-coil unit with fresh air system and the all air system.The study content mainly

includes: cooling and heating load calculation of air conditioning in the building;the

determination of the supply air volume and the fresh air volume;the air-conditioning system

division;the selection of modes of air conditonding system;the selection of air conditoning

equipment;the selection of the cold and heat source;the design and caculation of the air

system;the design of the air duct system; the determination of air supply mode and air

distribution mode;the design and the hydraulic calculation of the water system;the

determination of the cold and heat source;the thermal insulation design of the pipeline, the

design of the smoke prevention and exhaust and the design of noise elimination and

vibration prevention.This central air-conditioning design not only can satisfies the thermal

comfort but it ,to a great extent,can meets the command of building energy-saving.

Key Words: comprehensive building air-conditioning system the fan-coil unit with fresh

air system the all air system fresh air volume performance comparison building

energy-saving
