| Summary: | Industry processes are characterized by large amounts of energy losses dissipated as waste heat to the ambient. In industry sectors analysed in the US, China and EU28 low- temperature waste heat below 230ºC makes up from 33% up to 60% of waste heat. The recovery of low-temperature waste heat is usually complex, affected by the user demand, mismatches between the waste heat source and the user demand, limited space for heat recovery facilities, the heat-power conversion is not efficient for low-temperature waste heat, payback period, etc. The purpose of this paper is to present a methodology for technical and economic analysis of waste heat recovery. To address the issue of sensible criterion, methodology appropriate for small and medium enterprises is developed and in this paper, the user-friendly optimization integrating the heat exchange, energy conversion and heat storage is presented. A case study of waste heat recovery from an induction machine cooling system is used to demonstrate the applicability of the proposed methodology. The introduced methodology can simplify the heat pump integration process, and the proposed method can be further extended to other industrial processes for low-grade waste heat recovery. |
