MOBILE ACCUMULATORS FOR DISCRETE SYSTEMS HEAT-COLD SUPPLIES. Part 2. |
| description |
The purpose of this article is selection and substantiate the construct materials for a mobile battery of thermal energy. To evaluate the impact of chemical corrosion on the structural materials of the tank-battery, and researching the strength of the tank-battery during transportation and determination the feasibility of introducing and effectiveness of investments in environmental measures on the example of the implementation of the discrete heating / cooling systems. A comparison has been made of the technical characteristics chosen for our studies of heat storage material - bischofite and sodium acetate trihydrate, which showed that both substances have certain advantages and limitations in their application. An experiment was carried out to determine the stability of the material for corrosion, after the 10 cycles of heating-cooling, the metal parts that were deposited in the bischofite solution remained virtually unchanged, no corrosion marks were observed. While specimens that were in the melt of sodium triacetate have obvious corrosion marks (except for a stainless steel sample). Particularly noticeable corrosion of samples that were on the verge of air and sodium triacetate. Thus, it has been confirmed that the use of hydrated salt melts requires additional measures to protect against corrosion of metals, and the use of polymer materials is limited by the temperature of their application. Calculations of the strength of the tank-accumulator at static and dynamic loads with the account of transportation are carried out. Taking into account the obtained results of Mises stress, the tensile stresses in the cut and stresses of bolted joints during rolling during transport under conditions of use of steel constructions are higher. In the course of determining the feasibility of implementing the project, it was tested and proposed to supplement the methods of calculating the investment of energy saving measures and projects by a fundamentally new method of strategic rapid analysis "3E". This method allows you to get a graphical representation of the result of the analysis and with a high degree of probability to determine the strategy of financing the implementation projects. The analysis is based on three main criteria, namely: energy, environmental and economic. These weighting criteria consist of a number of values that are necessary to obtain a likely return on the payback of the implementation project. The results of express analysis are clearly represented in the form of the area of permissible values on the triangular diagram, which we are invited to call the "3E triangle" in the initial words of words: Energy, Ecology and Economics. An economic analysis has also been conducted, which showed that the estimated payback period of the project is less than five years, and the volume of annual revenue from the sale of thermal energy and cold is 1470000 UAH. Thus, the project is attractive for investment. |
