空调冷热源方案的多指标决策技术及应用

Technology and Application of Multiple Objective Decision in the Choice of Air conditioning Cooling /Heating Sources

在某大厦空调系统冷热源方案选择中，采用多指标决策方法，以方案设备初投资、增容费、运转费用、可靠性、占地面积与环境影响等为评价指标，建立了评价模型，对几种可能方案进行优序排列．结果表明，吸收式制冷方式具有一定的优势和潜力．燃煤仍较经济，直燃式溴化锂冷温水机组具有一些独特的特点和长处．蒸汽溴化锂冷温水机组加上燃煤锅炉是该空调系统冷热源的最佳方案．

The evaluation model is established on the objectives of first investment,electricity allowance cost,operation cost,system reliability,machinery room area and environment protection,with multiple objective decision for the choice of air conditioning system cooling/heating sources in a building.The several feasible schemes arranged in excellent order.The results show that absorption type refrigeration is of superiority and potentiality,coal fired type is more economical still,direct fired Lithiumbromide absorption water chiller/heater has distinctive advantage.The vapor lithiumbromide absorption water chiller/heacters and coal fired boiler are the optimum cooling/heating sources of the air conditioning system in this building.
