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.
In a building air-conditioning system, the choice of hot and cold source options, the use of multi-index decision-making methods to initial investment in equipment, capacity expansion costs, operating costs, reliability, area and environmental impact as the evaluation indicators, the establishment of the evaluation model, Ranking several possible scenarios. The results show that the absorption refrigeration has certain advantages and potential. Coal is still more economical, direct-fired lithium-ion water chiller has some unique features and strengths. Steam lithium bromide water heater with coal-fired boilers is the hot and cold air conditioning system, the best solution.
