TL;DR: Thermoelectric materials are solid-state energy converters whose combination of thermal, electrical, and semiconductor properties allows them to be used to convert waste heat into electricity or electrical power directly into cooling and heating.
Abstract: Thermoelectric materials are solid-state energy converters whose combination of thermal, electrical, and semiconducting properties allows them to be used to convert waste heat into electricity or electrical power directly into cooling and heating. These materials can be competitive with fluid-based systems, such as two-phase air-conditioning compressors or heat pumps, or used in smaller-scale applications such as in automobile seats, night-vision systems, and electrical-enclosure cooling. More widespread use of thermoelectrics requires not only improving the intrinsic energy-conversion efficiency of the materials but also implementing recent advancements in system architecture. These principles are illustrated with several proven and potential applications of thermoelectrics.

TL;DR: In this article, a thermodynamically orientated method is presented for the synthesis of heat exchanger networks, where preliminary networks are generated which give maximum heat recovery, and the most satisfactory final networks are evolved using the preliminary networks as starting points.
Abstract: A thermodynamically orientated method is presented for the synthesis of heat exchanger networks. With this method, the problem is solved in two stages. In the first stage, preliminary networks are generated which give maximum heat recovery. In the second stage, the most satisfactory final networks are evolved using the preliminary networks as starting points. In this paper, emphasis is given to the synthesis of the preliminary networks. Two four-stream examples are solved. In Part II, emphasis will be given to the synthesis of final networks.

TL;DR: In this paper, an experimental single stage heat transformer (SSHT) with water/carrol mixture was analyzed. But the performance of the SSHT was not evaluated. But four test runs were carried out in order to evaluate the performance and the heat powers were measured from 0.99 to 1.35.

TL;DR: In this paper, the effects of the thermodynamic parameters on the ORC performance were examined, and the optimal performance of different working fluids was compared and analyzed under the same waste heat condition.
