Construção de câmaras frigoríficas de congelamento pré-fabricado misto

Abstract

The storage and preservation of various substances dates to ancient times, and over the years new techniques have been created and used. After the creation of the first electric domestic refrigerator, in the early twentieth century, space was given for the creation of large refrigerated warehouses, the cold rooms, with large storage capacities and programmable temperature ranges. The use of techniques for the preservation and storage of perishable products becomes more necessary every day, and with increasing precision and efficiency. Having this need, this work aims to develop a demonstrative guide about the prefabricated mixed construction method for cold storage freezers, since the existing bibliography on the subject is scarce and there are currently no Brazilian standards. To prepare the guide, participant observation was used. Thus, there is the expectation that this work will help and serve as a basis for future elaboration of norms for the execution of cold rooms, aiming at the development of civil engineering in the country and the reduction of maintenance.
