Análise de sistemas frigoríficos destinados a bebidas de pressão

Abstract

Refrigeration systems for draught beverages are usually available in all kinds of catering services, being responsible to cool down different kinds of beverage from the environment temperature down to 3ºC. As they can be found in several thousand places and its operation runs for 24h per day and per year, the knowledge of its performance is relevant for the energy consumption. Thus, a common machine of this kind was fully instrumented with sensors to evaluate its behaviour. Additionally, it was used the EES software for simulations as well as tests were carried out in laboratory environment. Based on both results, strategies to improve their efficiency are discussed as well as the significant decrease in the energy consumption and associated CO2 emissions released by the power plants due to improvements that can be carried out in the working system.
