Abstract(s)
No presente trabalho são apresentados os principais sistemas de climatização tanto para aquecimento como para arrefecimento, para além de diversos sistemas de produção de águas quentes sanitárias. São também abordados aspectos relativos ao contexto nacional energético e ambiental, o plano nacional de eficiência energética, as condições de conforto termohigrométrico
interior nas habitações, os tipos de ventilação existentes e os diversos tipos de
energias renováveis utilizados.
A proposta desenvolvida no âmbito do presente trabalho, assenta em procedimentos de cálculo que, tendo como base o projecto de térmica do edifício do caso de estudo, permitem realizar a simulação de diferentes combinações de sistemas de climatização para aquecimento, arrefecimento e sistemas convencionais de produção de AQS. Conseguem-se comparar os valores obtidos em termos de emissões anuais de gases de efeito de estufa, o valor dispendido nas facturas energéticas anual e mensal para climatização e preparação de AQS, a classe energética
e o custo de aquisição, instalação e manutenção dos equipamentos.
In this work the main climatization systems were presented for both heating and cooling, in addition to various production systems for DHW. It also discuss issues related to the national energy and environmental context, the national plan for energy efficiency, interior thermohygrometer comfort conditions in housing, the existing types of ventilation and the various types of renewable energy used. The proposal developed in the scope of this work, is based on calculation procedures that, having the design of the building's thermal case study as a reference, can be conducted to simulate different combinations of climatization systems for heating, cooling and conventional systems for DHW production. Thus, it is possible to compare values obtained in terms of annual emissions of CO2, the amount expended on annual and monthly energy bills for climatization and preparation of DHW, the energy class and the cost of acquisition, installation and maintenance of equipments.
