Abstract(s)
A presente dissertação insere-se no âmbito de simulação energética de um projeto de climatização efetuado em gabinete de engenharia, no qual se pretende obter uma estimativa do consumo energético real da solução adotada através do cálculo termodinâmico efetuado em software Hourly Analysis Program (HAP). Devido a limitações de software utilizado em gabinete, recorre-se do programa DesignBuilder (DB) e da ferramenta de cálculo EnergyPlus por forma a validar o cálculo e considerações efetuadas em gabinete sendo, para tal, descritas as etapas principais do projeto, de acordo com os procedimentos observados em estágio no gabinete, no qual são introduzidos ambos os softwares utilizados. Apesar das limitações do HAP, verifica-se que o cálculo efetuado em gabinete é validado pelo EnergyPlus sendo posteriormente efetuada a simulação energética do sistema de climatização de acordo com os equipamentos selecionados em gabinete e apresentados em anexo. Adicionalmente, apresenta-se uma proposta alternativa ao projeto efetuado com a finalidade de melhorar condições de conforto e avaliar o custo associado ao controlo de um novo parâmetro de projeto. Esta solução, embora ideal a nível de condições interiores dos espaços, acarreta consumos energéticos bastante superiores à solução adotada em projeto pelo que demonstrou não ser uma opção viável.
This dissertation is part of the energy simulation of an air conditioning project carried out in an engineering office, which aims to obtain an estimate of the real energy consumption of the adopted solution through the thermodynamic calculation made in Hourly Analysis Program (HAP) software. Due to the limitations of the software used in office, both software DesignBuilder (DB) and calculation tool EnergyPlus were used in order to validate the calculation and considerations made in office. Despite the limitations of HAP, it is verified that the calculation made in office is validated by EnergyPlus thus the energy simulation of the air conditioning system is carried out according to the equipment selected in office and presented in annex. Additionally, an alternative proposal to the project is presented in order to improve comfort conditions and evaluate the cost associated with the control of a new design parameter. This solution, although ideal in terms of interior conditions of the spaces, leads to much higher energy consumption than the solution adopted in the project and therefore proved not to be a viable option.
