District heating networks are well-established technologies to efficiently cover the thermal demand of buildings. Recent research has been devoting large efforts to improve the design and management of these systems for integrating low-temperature heat coming from distributed sources such as industrial processes and renewable energy plants. Passing from a centralized to a decentralized approach in the heat supply, it is important to develop indicators that allow an assessment of the rational use of the available heat sources in supplying heating networks, and a quantification of the effect of inefficiencies on the unit cost of heat. To answer these questions, Exergy Cost Theory is here proposed. Thanks to the unit exergetic cost of heat, energy managers can (i) quantify the effects of thermodynamic inefficiencies occurring in the production and distribution on the final cost of heat, (ii) compare alternative systems for heat production, and (iii) monitor the performance of buildings’ substation over time. To show the capabilities of the method, some operating scenarios are compared for a cluster of five buildings in the tertiary sector interconnected by a thermal grid, where heat is produced by a cogeneration unit, an industrial process, and distributed heat pumps. Results suggest that moving from the centralized production of heat based on fossil fuels to a decentralized production with air-to-water heat pumps, the unit cost of heat can be decreased by almost 30% thanks to the improvement of thermodynamic efficiency. In addition, the analysis reveals a great sensitivity of unit exergetic cost to the maintenance in substations. The developed tool can provide thermodynamic-sound support for the design, operation, and monitoring of innovative district heating networks.

The development of sustainable energy technologies must be a priority given the rising global energy demand and global warming gases emission. In this work, the energy evaluation of a small-capacity direct-current refrigerator with internal heat exchange using R600a, R290, R717, and R134a as a base case, for autonomous solar refrigeration, is discussed. A thermodynamic model was developed to assess a 200 W refrigerator performance at evaporation temperatures of -32/-10 °C, condensation temperatures of 35/46 °C, and different internal heat exchanger effectiveness values while considering the environmental conditions in the city of Barranquilla whose metropolitan and urban area presents a great potential for solar refrigeration. Results showed that the R290 system coefficient of performance was up to 2.6% higher than that of the R134a. The R600a system coefficient of performance was up to 2.7% higher than that of the R134a, but only under the most favourable conditions. The R717 system surpassed the compressor discharge temperature limits so it was found unsuitable for the present application. Moreover, the internal heat exchanger was found beneficial to reduce the exergy destruction in the compressor and expansion valve but increased that in the condenser for R134a, R600a, and R290. The internal heat exchanger recommended effectiveness should be around 0.4 for R600a or 0.3 for R290 at an evaporation temperature of -32 °C. For an evaporation temperature of -10 °C, the IHX effectiveness can be up to 0.5 for both R600a and R290. Finally, the maximum power consumption of the solar R290 refrigeration system was estimated around 4.08 kWh and 2.28 kWh at evaporation temperatures of -32 °C and -10 °C, respectively, which could be covered by a solar panel area of 3.76 m 2 y 2.10 m 2 , respectively, while similar values were obtained for the solar R600a refrigeration system.
