溴化锂吸收式制冷机在热电联产机组应用的节能分析

以热电冷三联产系统为对象,建立以热电比、热效率、制冷机性能系数以及分产参考系统的热力性能参数表示的联产系统,比分产系统易于工程应用。对此,以实际热电联产机组为例进行计算验证,表明三联产机组节能是有条件的,节能多少的关键取决于对供热机组的合理选择。吸收式制冷机对三联产系统节能率的影响很小。

ENERGY-SAVING ANALYSIS OF APPLYING LITHIUM BROMIDE ABSORBING TYPE REFRIGERATING MACHINE INTO HEAT AND ELECTRICITY CO-GENERATION UNIT

Taking the heatelectricitycool triplex cogeneration system based on heatandelectricity cogeneration system as the object, a cogeneration system represented by heatelectricity ratio, thermal efficiency, performance coefficient of the refrigerating machine, as well as thermal performance parameters of the separating production reference system has been established from basic energy consumption of the system, the said cogeneration system is more convenient applied to engineering project than the separating production system. For this, taking practical heatandelectricity cogeneration unit as an example, calculation and verification have been carried out. Results show that the energysaving of triplex cogeneration unit to be conditional, the key of energysaving magnitude to be determined by reasonable selection of the heatsupplying unit. The influence of absorbing type refrigerating machine upon enorgysaving rate of the triplex cogeneration system to be very little.
