For different energy source type and different switch targets, the transition form of the energy is also not quite similar.Wherein the chemical energy thermotropism of fossil fuel and the conversion of merit are as the important form of power conversion, not only in " quantity ", effectively will change chemical energy as much as possible, also need to consider the characteristic in energy figure conversion aspect simultaneously.Only consider the quantity of energy and the attribute of quality two aspect, scientifically can judge whether energy is fully used.In fact every conversion process of energy carried out with certain orientation and certain limit, energy figure will decline.And can cascade utilization principle be exactly Energy harvesting guideline for how to reduce this quality and " belittle ", this theory also points out that energy figure exists height difference, only have and utilize step by step or conversion of energy, and reduce the difference between two-stage as far as possible, effective utilization of energy can be realized.Based on this, in conjunction with the acting process of Gas Turbine Generating Units, the waste heat making full use of high-temperature flue gas drives absorption refrigeration unit, achieves the efficiency utilization of fume afterheat to a certain extent, solves the deficiencies such as the comparatively large and process of refrigerastion power consumption of power generation process low-temperature heat source loss is larger simultaneously.

Dynamic power circulation and kind of refrigeration cycle are the independent energy transfer processes of series connection mutually, and in actual application, the demand of user to electric energy and cold energy is real-time change, and amplitude of variation is not identical yet.For the energy conversion structure of series connection, the electric energy exported and cold energy are mutually certain proportion, simultaneously in variable working condition adjustment process, this dissimilar Energy transmission ratio also almost remains unchanged, and this also regulates this system variable parameter operation and proposes higher challenge.On the other hand, although the cooled circulation of high-temperature flue gas waste heat is reclaimed, also the counterpart substantially achieving energy grade utilizes, but how to improve the utilization ratio of fume afterheat further and expand the application of fume afterheat, also will become the important subject in energy source use field.
