Abstract

This article describes how an energy audit of equipment and the resulting design changes can have a major impact on reducing the electricity consumption of refrigeration equipment. The legal basis introduced by legislation forcing work on the improvement of refrigeration unit is provided. Eight points detail and describe the changes applied to the construction of cooling units. Additionally, a list of the refrigerants which are used is presented, along with the essential parameters of their work. The following analysis includes a description of the research performed along with the measured and calculated results for individual optimisations. The basic parameters that were used for comparison are: daily electricity consumption [kWh/24 h] and the temperature of the packages placed in the device [°C]. Finally, the percentage differences in energy consumption for each modernisation are summarised in a tabular form. The device used for the tests was the VARNA refrigerated rack, model 900, manufactured by P.P.H.U. JUKA Sp. z o.o. sp. k.
