Implementing energy efficiency measures to construct a commercial refrigerator with solar photovoltaic power supply. Cienc. Ing. Neogranad. [online]. 2022, vol.32, n.2, pp.61-84.  Epub 30-Dez-2022.

The high energy consumption of refrigerators and an intermittent power supply increase the electric bill cost and affect refrigerated products, respectively. This is the opinion of several shopkeepers who purchase this equipment for commercial activities. These problems are of concern to the manufacturer, which considers that the supply of its equipment could be affected. This article aims to build a more energy-efficient commercial refrigerator supplied with solar photovoltaic energy. The development begins with an energy balance of a conventional refrigerator to identify possible energy improvements. Subsequently, four measures are implemented to construct a refrigerator with higher energy performance and a solar photovoltaic installation, which provides reliable electricity. It is concluded that, through timely energy management, it is technically and economically feasible to build efficient refrigerators that operate with clean and renewable energy.

Palavras-chave : refrigerator; energy efficiency; solar energy; energy consumption; energy performance.
