Analysis of inovative sale system (vending machine), independent of energy, of cold and hot products

In the current energetical context, there is a need to diversify energetically independent applications. The presence of energetically independent vending systems is necessary in the smart cities of the future and beyond. Energetically independent vending equipment must ensure the delivery of cold or hot products with low energy consumption. Reduced energy consumption and the use of environmentally friendly sources lead to reduced greenhouse gas emissions and at the same time to higher energy autonomy. The paper presents the results obtained from testing the innovative experimental sales system developed to study the energetic efficiency of this equipment. The innovative sales system is a complex system that integrates energy production and storage, cooling and heating systems. The fully automated system allows cold storage of products and their subsequent delivery, cold or hot, on demand. The vending system was powered by electrical energy from an array of photovoltaic panels. The results obtained, summarized in the paper, lead to the possibility of developing stand-alone vending equipment with significant reduction of greenhouse gas emissions in urban agglomerations.
