摘要
结合工程实例,对6种冷、热源方案进行了火用经济分析。6种方案为:采用离心式冷水机组供冷,燃油锅炉供热;采用直燃式溴化锂吸收式冷热水机组;采用风冷螺杆式冷水机组供冷,燃油锅炉供热;采用蒸汽双效溴化锂吸收式冷水机组供冷,燃油锅炉供热;采用水源热泵;采用螺杆式水-水热泵。方案4最优。
Taking engineering for example, an exergoeconomic analysis is made about six kinds of schemes for heat and cooling sources, including using centrifugal chiller for cooling and oil-fired boiler for heating, adopting direct-fired lithium-bromide absorption-type water chiller-heater unit, using wind cooled screw chiller for cooling and oil-fired boiler for heating, adopting steam double lithium-bromide absorption-type chiller for cooling and oil-fired boiler for heating, using water- source heat pump, and adopting screw water-water heat pump. The fourth scheme is optimum.
