Diseño e instalación de un sistema de energía renovable para un edificio

This project seeks conduct a technical and economic study of a solar thermal and other of biomass in the residence "T16" located in Wroclaw, Poland. We will proceed to a remodeling of that building, in which to improve energy efficiency and insulation have introduced various systems in the building structure that reduce energy losses thereof. Two clear examples of this are the introduction energy improvement Coteterm insulation in the building's facade, with large insulating qualities that reduce our heat loss, and other insulation in the walls of the inside of the building. Another aspect in this summary is the modification of the stairs to so to comply with Fire Technical Code. Here are three examples of multiple renovations we have done to the building. Furthermore, in this study we wanted to explore existing technologies in renewable energy and we better come to our climatic and geographical area (Wroclaw). After an exhaustive study, we determined that the two best technologies for our building would be solar thermal and biomass boilers. This residence has an annual heat demand 1.809,127 kWh, divided into two parts according to what your consumption: Heating (1.118,272 kW), hot sanitary water (HSW) (690,855 kWh). This demand will be met by a solar collection system and a biomass boiler system. In this project we have tried to make a design of the installation which on the one hand as efficient as possible from the point of view of energy and on the other hand that its use as comfortable as possible for the rooms of the building in question, all without subtract services or guarantees the design of it. This has been achieved with a centralized solar collection facility for HSW and other of biomass accumulation installation for hot sanitary water and central heating, and auxiliary power production through online for the entire building (electricity), taking into account that all users of this get the same benefit of the solar and biomass. For the selection of collectors has made a study of various offers by an Internet search. We selected a set of plate collectors that we believe may be more representative. We chose collectors with an average price and standard technical specifications, since the purpose of this project is to evaluate the different brands and models, but comparisons between the various boards to see which gives better performance at a lower price. These models of flat plate collectors are: Veissmann Vitosol 100-F, Veissmann Vitosol 200-F, Veissmann Vitosol 300-F, Ecosol sol 2300, Ecosol sol 2800, Ecosol sol 2800-H. Given these considerations, we analyzed the thermal production for our catchment area available. After this analysis we have discarded all the solar cells less Veissmann Vitosol 200-F and 2800-H Ecosol sun. These two alternatives have been subjected to an economic study. The result of this study is the selection of the most cost effective installation option. We choose Ecosol sol 2800-H model as the installation cost difference compared to Veismann 200-F model is much higher than the difference in cost of energy consumed by both collectors. The solar installation consists of 63 flat plate solar collectors, SOL brand 2800-H, which convert solar radiation into thermal energy, which must be transported and stored in storage tanks for later use as hot sanitary water (HSW). The solar installation is fully regulated by an electronic regulation and control devices which act on the installation and all data stored for further analysis in the maintenance of the same. Installation of biomass contains 6 biomass boilers TUERO brand TUERO 48 model , which have a power of 48 kW each of the boilers. All boilers are connected in series, in order to make more efficient regulation of the energy needs. These 6 boilers is fed by a worm systems from a silo located at the rear of the boilers. This silo is filled six times a year in order to meet all the annual energy demand. In addition to the facilities mentioned above, there will be a backup system, according to the CTE, for those moments when you have energy deficit by both facilities or there is an emergency situation. This auxiliary system is based on electricity. To accumulation system we can talk about two different storage volumes, the solar system and the system of biomass boilers. The solar collection system consists of two tanks of 5.000 liters and will be used only for the thermal system dedicated to heating hot water (HSW). The system of accumulation of biomass boilers consists of 4 tanks 5.000 liters, enough to store the energy generated by the boilers. Designed solar installation will cover 11.52% of annual hot sanitary water (HSW) and designed biomass installation will cover the remaining energy needs of the building.Ingeniería Industria
