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.
