Resumo: | A controller for thermal systems is normally equipped with many facilities to make it flexible and the heating systems more cost-efficient. This results in a number of input parameters to be given by the user. It is not obvious how to choose appropriate values for these parameters unless the user has a large experience in this field. Water heating is a very important part of a household's energy use, and tankless gas water heaters (TGWH) are widely used. There are design and engineering challenges to develop more efficient devices, with lower emissions of pollutant gases and providing comfort improvements from the user point of view. Mathematical and semi-empirical models of the thermal systems were developed in order to simulate the dynamic models of water heating devices. A simulated environment is a less expensive and fastest way of evaluating the relative merits of different control schemes for a given thermal system. A technique to accelerate the process for developing controllers was implemented. Hardware-in-the-loop simulation (HILS) has proved to be very useful to test hardware controllers in virtual environments simulated in real-time. In the scope of the Smart Green Homes Project, a virtual test bench with a TGWH was proposed to support the multiple phases of controller's development, whether it is to control a real or a virtual system. The experimental platform was developed to test the implemented hybrid models performance in hardware-in-the-loop simulation experiences. The platform is composed by a TGWH with a group of sensors, by real-time hardware and by a package of software tools for data acquisition and control. In the final stage of this work, two case studies were carried out, in which the first was dedicated to the validation of the virtual bench concept and the second was to control and monitor a water heating device. Very satisfactory results, from a set of HILS experiences performed in real-time simulations, were obtained for the semi-empirical models proposed. |

Isto resulta numa série de parâmetros de entrada a serem dados pelo utilizador. Não é óbvio como escolher valores apropriados para estes parâmetros, a menos que o utilizador tenha uma grande experiência neste campo. O aquecimento de água é uma parte muito importante do consumo de energia de um agregado familiar, e os aquecedores de água a gás sem tanque (TGWH) são amplamente utilizados. Há desafios de projeto e engenharia para desenvolver dispositivos mais eficientes, com menores emissões de gases poluentes e proporcionando melhorias de conforto do ponto de vista do utilizador. Foram desenvolvidos modelos matemáticos e semi-empíricos dos sistemas térmicos para simular os modelos dinâmicos dos dispositivos de aquecimento de água. Um ambiente simulado é uma forma menos dispendiosa e mais rápida de avaliar os méritos relativos de diferentes esquemas de controle para um determinado sistema térmico. Foi implementada uma técnica para acelerar o processo de desenvolvimento de controladores. A simulação Hardware-in-the-loop (HILS) provou ser muito útil para testar controladores de hardware em ambientes virtuais simulados em tempo real. No âmbito do projecto Smart Green Homes, foi proposta uma bancada de ensaios virtual com um TGWH para apoiar as múltiplas fases de desenvolvimento do controlador, seja para controlar um sistema real ou virtual. A plataforma experimental foi desenvolvida para testar o desempenho dos modelos híbridos implementados em experiências de simulação hardware-in-the-loop. A plataforma é composta por um TGWH com um grupo de sensores, por hardware em tempo real e por um pacote de ferramentas de software para aquisição e controlo de dados. Na fase final deste trabalho, foram realizados dois estudos de caso, em que o primeiro foi dedicado à validação do conceito da bancada virtual e o segundo foi para controlar e monitorizar um dispositivo de aquecimento de água. Foram obtidos resultados muito satisfatórios, a partir de um conjunto de experiências HILS realizadas em simulações em tempo real, para os modelos semi-empíricos propostos.2021-07-26T00:00:00Z2019-07-18T00:00:00Z2019-07-18info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10773/28184engOliveira, Jonathan Danielinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-02-22T11:54:33Zoai:ria.ua.pt:10773/28184Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:00:47.899828Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |

A controller for thermal systems is normally equipped with many facilities to make it flexible and the heating systems more cost-efficient. This results in a number of input parameters to be given by the user. It is not obvious how to choose appropriate values for these parameters unless the user has a large experience in this field. Water heating is a very important part of a household's energy use, and tankless gas water heaters (TGWH) are widely used. There are design and engineering challenges to develop more efficient devices, with lower emissions of pollutant gases and providing comfort improvements from the user point of view. Mathematical and semi-empirical models of the thermal systems were developed in order to simulate the dynamic models of water heating devices. A simulated environment is a less expensive and fastest way of evaluating the relative merits of different control schemes for a given thermal system. A technique to accelerate the process for developing controllers was implemented. Hardware-in-the-loop simulation (HILS) has proved to be very useful to test hardware controllers in virtual environments simulated in real-time. In the scope of the Smart Green Homes Project, a virtual test bench with a TGWH was proposed to support the multiple phases of controller's development, whether it is to control a real or a virtual system.
