Analysis of Refrigeration Energy Consumption under a Tri-generation Production Mode as Compared with That under a Single Electric Power Production Mode

In accordance with heat quantity balance method an analysis is performed of the refrigeration energy consumption under a tri-generation (electric power, heat energy, cooling energy) production mode and a single electric-power production one. A method is presented to compare energy consumption under various conditions. It is concluded that in general the refrigeration energy consumption under the tri-generation mode will be greater than that under the single electric-power production one. The proposed method has provided a basis for the comprehensive study and comparison of refrigeration energy consumption under the tri-generation mode and the single generation one.
