文档介绍：摘要
随着我和居民生活质量都有了很大的提高,空调系统的运用越来越广泛。空调系统的能量消耗也越来越多,为了进一步降低空调系统的生产成本,有关人员在工艺方面进行了改进和优化设计,建立模型,确定主要工艺参数与系统传热传质之间的关系,得到了局部条件下的最优解。不管是从工艺上还是从设备上,任何改进和优化的目的都是想得到相应条件下的最优解。但是,参数的改变不仅影响到工艺的改变,还影响到设备的投资和运行性能的变化。一般而言,技术的进步和资金的节约往往是相互矛盾的,如果技术的进步所带来的收益不能弥补投入资金的增加值,那么这种技术的改进是没有现实意义的。因此,我们选用综合的评价指标:热经济学指标。热经济学是把热力学分析与经济因素结合的交叉学科。该学科的基础是热力学基础和经济学基础,并能熟练地运用现代最优化技术,在本文中,我将结合实际计算单位热经济学成本,通过建模,实验,计算出该设备的热经济学单价成本。
Abstract
With the great development of our country’s economy, the level of industry and people’s living quality have had a great improve, and much mor air condition system is required,so more air condition ’energy is further lowering the production cost of the air condition system,Some men carried on the improvement the craft and designed excellent form, built up the model, made sure that the main craft parameter and systems transmit heat to spread the relation between quality, get under partial condition of superior solution. Ignore to still is from the craft from the equipments, any improvement and excellent the purposes that turn are all want to be correspond under condition of superior solution. But, the change of the parameter not only affects the change of the craft, but also affects the investment of the equipments and the variety of the movement functions. Generally speaking, technical progress and the economy of the fondues are usually conflicting, if the e that technical progress bring can't make up the increment value of throw in the funds, so this kind of technical improvement have no realistic meaning. Therefore, we choose to use prehensive evaluation index sign
. Hot economics index sign. The hot economics is bine the analytical and economic factor of thermodynamics of cross the course. The foundation of that course is the thermodynamics foundation and the economics foundations, and can make use of the modern expertly superior turn the technique, in this text, I bine the hot economics cost of actual calculation unit, passing to set up the
