On 11 and 12 November, the Public University of Navarra's biennial Congress of Cold Science and Techniques CYTEF 2020 was held virtually, with the participation of three of Frost-trol, S.A.'s collaborators.

This congress brings together the best experts and researchers related to refrigeration, food preservation, air conditioning and energy efficiency, both from the industrial sector and the universities.

Alejandro Sáez, PhD student and Frost-trol Engineer, has participated in the first day, presenting the study "Refrigerated Cabinet Modelling Based on the Charactersation of R290 Behaviour" carried out together with the technical engineering group of the Universitat Jaume I.

The aim of the study was to achieve a technological advance in terms of the energy performance of the refrigeration equipment manufactured at Frost-trol.

For this purpose, a tool was developed for the design of the cabinets, optimizing the dimensioning and the real operation, with a decrease in the manufacturing costs, as well as an increase in the energy efficiency of the cabinet and a decrease in the environmental impact.

In the morning session of the second day, Jorge Patiño, PhD and Technical Director of Frost-trol, presented the work carried out jointly with the R&D Department for the development of an integrated system with the production and quality management processes in a production line.

The aim of this system is to design equipment that complies with the restrictions set out in the regulations and, at the same time, to develop technologies that allow the quality of the cabinet to be improved.

I have concluded with our participation in the Congress, Lledó Prades, PhD and Engineer in the R&D Department of Frost-trol.

Lledó, presented the study "Parametric Evaluation of Closed Refrigerated Display Cabinets Performance", carried out with her colleagues in the department.

The aim of the study was to achieve progress in modelling flow and temperature distributions in the interior cavity of freezer cabinets. To this end, Computational Fluid Dynamics (CFD) models were developed and implemented, which made it possible to evaluate the effect of buoyancy forces and the flow discharged by the rear panel on the cabinet's air curtain. All this has helped in the characterisation of the operation of the cabinet, and its optimisation in its real operation.
