CRUZ FONTICIELLA, Oscar M  e  DOS REIS PARISE, José A. Structural study of heat pump´s installations. Energética [online]. 2013, vol.34, n.2, pp. 119-128. ISSN 1815-5901.

The irreversibility of a heat pump with exergy and structural analysis is investigated. An experimental installation of a heat pump and calculations achieving data compression efficiency, the average temperature of hot and cold spots in the cycle was used, The temperature difference output condenser, log mean evaporator , pressures drops condenser and evaporator and structural exergy analysis and thermodynamic properties at key points of the cycle, the cycle coefficient of performance, mass balances, energy and entropy, entropy generated in each component, the availability balance irreversibilities in each component , exergetic efficiency, default coefficients efficiency and structural links were obtained. The potential for improvement for each component for further thermoeconomic optimization were explored.

Palavras-chave : structural analysis; exergetic analysis; heat pump; coefficient structural bonds; irreversibilities.
