Combined Heat and Power From Low Temperature Heat: HFO-1336mzz(Z) as a Working Fluid for Organic Rankine Cycles

摘要

HFO-1336mzz(Z) is evaluated as a working fluid for combined heat and power generation from low temperature natural or waste heat with reduced environmental impact. HFO-1336mzz(Z) safety, health, environmental, chemical and thermodynamic properties are reviewed and new data on the miscibility and viscosity of mixtures of HFO-1336mzz(Z) with ISO 220 and 320 polyol ester lubricants are reported. HFO-1336mzz(Z) Organic Rankine Cycle (ORC) performance was measured in an un-optimized prototype system at an expander inlet temperature of 196 °C and at condensing temperatures of 60 °C and 80 °C. Measured net thermal efficiency and net mechanical power capacity exceeded 10% and 10 kW_(mech), respectively.
