Diseño y simulación de un cuarto frío para la conservación de 250000 plántulas de fresa.

Abstract

Bioproduccion is a warehouse of agricultural inputs whose main activities are, sale of agricultural inputs and sale of seedlings of strawberries to farmers in the area. The objective of the present titration project is to design and simulate a cold room for the conservation of strawberry seedlings (Fragaria). For its realization, the necessary information was gathered about the storage of strawberry seedling, refrigeration cycles, refrigerants and cold rooms. With these data we proceeded to calculate the thermal loads according to Ashrae which are: load by transmission, load of the product, loads by infiltrations of air , internal loads; the sums of these loads gives me the total thermal load to which 10% is increased by factor of safety, to allow possible discrepancies between design criteria and current operation, whit this thermal load is proceeded to the selection of equipment for this helped catalog and software oh choice which facilitated the process, lago of the selection of equipment proceeded to request quotations of the equipment and accessories selected, in addition we consulted on the cost pf labor, since with these data was made the cost analysis , which evidenced that it is viable project since the investment will recover in a year and a half. The design of the cold room was enhanced in the SolidWorks program and the thermal analysis was carried out in the ANSYS simulation software and it is verified that the temperature of the seedlings was correct. In conclusion, with the selected equipment, correct storage of the strawberry seedlings is ensured.
