Abstract

Still technological development is associated with huge energy consumption, and thus with the increasing use of constantly decreasing fossil fuel resources, the formation of greenhouse effect and an increase in atmospheric pollution with combustion products. In connection with the constant, increasing global energy consumption, including for refrigeration purposes, it is necessary to promote modern, cost-effective technologies that enable energy recovery in sanitary installations. This article discusses the problem of utilization of waste heat from the refrigeration process and presents the possibilities of acquiring this wasted heat and objectives of its use. The article was prepared on the basis of a technical and technological design of a real object in Wroclaw, which is a self-service grocery store.
