Research On Energy-saving Technologies Of Complex Energy Systems And Equipments

In order to analyse and optimize complex energy systems, the three aspects can be discussed below. Firstly, the exergy can be studied which is usually easy to produce different meanings, and therefore it must be researched completely. Secondly, the network thermodynamics can be presented to solve highly complete and non-linear systems. Lastly, the integrated evaluation can be obtained by using technology and economy in complete energy system.There are four properties about the exergy, that is nature property, societal property, relative property and generalized property. Exergy can be described as an energy flow or matter flow, that can be used for any kind of enery with enery system analysis. Exergy is described as an order character and self-organized structure. All the life systems have a development direction on maximal exergetic capacity. However, exergy is a potential measure that is relative to reference state, and its value is described as an distance far from its equilibrium state, therefore it has a relative property, which expresses the quality exeeding the reference state. It has also a generalized character, and can analyize the nature and societal phenomena far from equation state. An example has been studied based on exergy analysis method, and an energy system model of a coal fired power plant has been obtained to be calculated and analysed by using the exergy estimatation index. The generalized thinking character of the exergy is studied in public organization, and points that the development about individuals just upgrades the force exergy potentials of crowds. And the development fundamentality of crowd organization is improved at large on the potential exergy standard.Network thermodynamics is a thermodynamic analysis method based on Kirchhoff network, and describes the energy system structure with topology parameters and geometry parameters to obtain the modelling, the matrix expression, and the results by using correlated law and theorem and thermodymic charaters. A high-voltage electrical pulse conductance way of drug transport through skin is studied by using the network thermodynamic analysis method, and modeled by topological structure. The calculated results show that the high-voltage electrical pulse conductance way is easy to conduct more drug liquid capacity to cure of some diseases, therefore this method can be appplied.The key problem about thermoeconomics is product-costing and energy flow structure. The thermoeconomic analysis model is established on the marginal exergy cost, and has the influence of cost change inside the energy system on the entire exergy consumption of the system. The product performance indices are calculated and compared about the components in the coal fired power plant to study the problem of the energy structure and costing, and so we have a stress improvement requirement in the boiler component. Also the model is obtained about the unit thermoeconomic cost of an air-conditioning system, and shows that the saveing-energy emphases is on the compressor and the most ideal condition state is at a16℃of evaporizing point in the condenser, and the economic operation mode of the condensate bump in the air conditioning system is decided by thermoeconomics. Finally, the paper has a modelling optimization strategy about thermoeconomics in the operation of a power plant, and the optimization strategy plan of the model calculation virses is obtained based on the date of some practice conditions in the power plant.
