Implementación de un cuarto frío para el laboratorio de semillas del centro BIOFORESTA, de la facultad de recursos naturales, de la Escuela Superior Politécnica de Chimborazo.

Abstract

In the Faculty of Natural Resources, the BIOFORESTA laboratory; is a place where practices and researches on forest sedes are conduced as well as it examines the forest genetic improvement by solving both reproductive problems and conservation of natural resources. Previously the laboratory did not conduct research and practice regularly since it did not count on an installation of a suitable cooling system for seeds, the project analyzed the implementation of a cold room as well as the appropriate maintenance actions for the refrigeration chamber. A good preservation is essential because it influences directly in the quality of plants and products to be obtained later, which are sold to local and national plant nurseries. At titling work, the initial state of cold storage was evaluated and the absence of the condensing unit was determined, also, calculations of thermal loads were made in order to achieve proper sizing of the cooling components, the assembly and implementation were carried on according to safety regulations for refrigeration installations. The analysis of the tachnical condition of the installation was conducted by evaluating selective aspecsts, and directive parameters in each of the equipment. The underlying reasons which cause deterioration of the cold room and reduce the benefits of the production process were analysed. The next step was to encode the equipment in order to make every person capable to find the exact location of them. Maintenance actions base don periodic inspections that avoid the consequences of premature failures, reduce downtime and repair costs, were established. The project was complemented by the development of a manual operation and a bench of maintenance activities for the refrigerating installation system.
