Resumo(s)
This chapter reports an overview about experimental studies concerning the thermal performance of
air curtains and heat exchangers installed in vertical open refrigerated display cases. The air curtain
analysis shows the influence on the thermal performance by varying the width of the discharge air grille
and the perforation density of the back panel by a mathematical model. The variation on the perforation
density of the back panel and the width of discharge air grille alter significantly the thermal entrainment
factor and the energy consumption of the equipment. Focusing the influence of environmental conditions
on the performance of the heat exchanger, a second mathematical model was developed to evaluate the
total heat load, its partial components and the condensate water mass. This analysis provides valuable
information to the design of the air curtain and heat exchanger based on in-store environmental conditions
and airflow efficiency.
