Comparison and analysis of performance using Low Temperature Power Cycles
Henrik Öhman,Per Lundqvist +1 more
TL;DR: Low temperature power cycles have become increasingly interesting means of increasing energy efficiency of processes as well as for base load power generation from solar, and geothermal, heat as discussed by the authors, and have been shown to be a promising energy efficiency method.

Implementation and evaluation of a low temperature waste heat recovery power cycle using NH3 in an Organic Rankine Cycle
TL;DR: In this paper, the authors present field data and analysis of an ORC power generation plant operating with NH3, which operates on waste heat from a Swedish pulp mill at an available temperature of 75 to 85 °C.

Theory and method for analysis of low temperature driven power cycles
Henrik Öhman,Per Lundqvist +1 more
TL;DR: In this article, a combination of traditional first law and second law analysis was used to facilitate characterization and comparison of power cycles using low temperature heat sources, and a new method was developed to facilitate power cycle characterization using low-temperature heat sources.

Screw expanders in ORC applications, review and a new perspective
Henrik Öhman,Per Lundqvist +1 more
- 01 Jan 2015
TL;DR: In this paper, the performance of organic rankine cycle is sensitive not only to the entry temperature ratio between heat source and heat sink but also to the temperature degradation of the heat source flow.
Global Efficiency of Heat Engines and Heat Pumps with Non-Linear Boundary Conditions
Per Lundqvist,Henrik Öhman +1 more
TL;DR: This article presents how a thermodynamic “black box” method for defining and comparing thermal efficiency of different size and types of heat engines can be extended to also compare heat pumps of different apparent magnitude and type.
