摘 要

本设计中比较了电机驱动的蒸气压缩循环冷水(热泵)机组、溴化锂吸收式冷水机组(直燃型、蒸汽型) 、空气源热泵、地源热泵、冰蓄冷、电（燃油、燃气）锅炉等冷热源方案的年能源消耗量、运行费用、初投资、环境影响。

最终确定空调系统采用电制冷 燃油锅炉的方案，与其他几种方案相比，此方案全年费用较低，CEC值很小，所以能源利用率很高，且CO₂和SO₂年排放量相对较低。

Design of cold and heat source for air conditioning system

of Hua Fu Buiding in Wuxi

Abstract

Energy consumption,operation cost,initial investment and environmental impacts in cold and heat source project are compared in this design, including motor driven vapor compression cycle water chiller(heat pump),lithium bromide absorption chiller(direct combustion type and steam type),air source heat pump,ground source heat pump, ice storage cold and electric boiler(fuel,gas).

The electric refrigeration and fuel oil boiler is determined as the final project of the air conditioning system, while comparing with several other projects，the annual cost of this project is lowest, and the CEC value is very small, so the energy utilization rate is very high, what’s more, the emission of CO₂ and SO₂ is relatively low.
