Abstract

In order to be shown in detail, the design process algorithm (see Fig. 2 in Chapter “ Structural Design of the mCCHP-RES System”) was divided into two stages, namely structural design and functional design. In Chapter “ Structural Design of the mCCHP-RES System” was presented the first stage while in this chapter is presented the second. Then, in Chapter “ Experimental Case Study” it is shown a concrete example. Here, the functional design was divided into five steps and to each step has been devoted a paragraph. Regarding the contents of steps, this is as following: In the first step (described in Sect. 2.1) the acceptable structural models resulted from the structural design stage, are completed with all the complementary components (such as recirculation pumps, expansion tanks, heat exchangers etc.), this way becoming the functional models of the system. After that all the components, main or complementary, are dimensioned taking into account both the energetic consumptions of the residence and the internal energetic consumptions of the system. The next two steps (described in Sects. 3 and 4) consist in establishing the operation and control strategy of the system, based on which then the system dynamics is analyzed numerically. Simulation and analysis of the system operation highlights the system performance in critical moments (such as the coldest/hottest day of the year, for example), in case of each functional model. The step described in Sect. 5 consists in designing the monitoring and control subsystem, which includes choosing the field equipments, design of the connection devices of these equipments to the data acquisition system, design of the monitoring software of the whole system, as well as designing the numerical controllers of the thermal and electric control loops. The last step (described in Sect. 8) consists in designing the system interfaces. Finally, the system designer has at his disposal several functional models, each with advantages and disadvantages, and, on this basis, can make the best decision.
