Abstract(s)
Nos edifícios de serviços, nomeadamente os espaços comerciais como supermercados ou
hipermercados têm a eles associados dois grandes tipos de instalações: Refrigeração e
Climatização.
A primeira é responsável por garantir as condições de conservação dos produtos que se
encontram armazenados ou em exposição para venda, enquanto a segunda é responsável por
garantir as condições termohigrométricas e de qualidade do ar interior necessárias para o
conforto e bem-estar dos trabalhadores e clientes.
É prática comum do mercado nacional estas duas instalações serem concebidas, projetadas e
posteriormente instaladas de forma completamente independente uma da outra, apesar de ambas
se basearem fundamentalmente nos mesmos princípios termodinâmicos.
O presente trabalho tem como objetivo conceber um sistema de refrigeração e climatização de
forma integrada, procurando quais os pontos comuns entre os sistemas passiveis de interligação,
seja por processos de recuperação térmica ou por associação de sistemas.
Aplicou-se este princípio na conceção de um caso de estudo, um supermercado localizado em
Rio Maior, sobre o qual se fez uma análise de cargas térmicas tanto para o sistema de
refrigeração como para o sistema de climatização.
Após o balanço térmico do espaço, idealizou-se o tipo de instalação a desenvolver, seguindose
toda a seleção de materiais e equipamentos a utilizar e caracterização de uma filosofia de
comando e controlo da instalação.
Como produto final deste caso de estudo, obteve-se um projeto teoricamente funcional e de
possível execução e implementação.
Service buildings, namely commercial spaces like supermarkets or hypermarkets, are associated with two major types of facilities: Refrigeration and Air Conditioning The first is responsible for ensuring the conservation conditions of products that are storaged or on display for sales, while the second is responsible for ensuring the necessary indoor air quality for comfort and well-being for those that occupy the facility. It’s common practice in Portuguese national market that these two installations are thought, designed and installed in complete independence from one another, although both are fundamentally based in the same thermodynamic principles. The following document has the goal of conceiving a system for refrigeration and air conditioning that function in an integrated manner, searching for common point between these systems that are liable to interconnection, either by thermal recovery processes or by system association. This principle was applied in the conception of a case study, this being a supermarket located in Rio Maior, over which was made a thermal load analysis both for the refrigeration system as for the air conditioning system. After the thermal load study, the type of installation to develop is idealized, following that all the materials and equipment selection as well as the definition of the command and control philosophy for the system. As a final product of this case study, we have a theoretically functional project of possible execution and implementation.
