Ormat Rankine Cycle Configurations for Utilization of Low Temperature Heat Sources
Volume 1: Advanced Energy Systems; Advanced and Digital Manufacturing; Advanced Materials; Aerospace, 2008Concerns about the effect of CO2 emissions on climate change and rising energy costs have renewed the interest in efficiency improvement in fossil fuel use as well as the utilization of locally available low or moderate temperature heat sources, such as geothermal or solar.

Development of Advanced Absorption Systems Driven by Low Temperature Heat Sources
1993Two refrigerants 1,1,1,2-tetrafluoroethane (R134a) and 2-chloro-1,1,1,2, tetrafluoroethane (R124) that are alternatives to chlorofluorocarbons, in combination with two absorbents N,N’-dimethylacetamide (DMAC) and dimethyl ether tetraethylene glycol (DMETEG) were evaluated for possible utilization in absorption machines powered by low temperature heat ...

Working fluids for low-temperature heat source
Applied Thermal Engineering, 2010Abstract The performance of different working fluids to recover low-temperature heat source is studied. A simple Rankine cycle with subcritical configuration is considered. This work is to screen working fluids based on power production capability and component (heat exchanger and turbine) size requirements. Working fluids considered are R134a, R123,

Management of Low-Temperature Heat Source by ORC Aided by Additional Heat Source
Applied Mechanics and Materials, 2016In the paper presented is a concept to utilize waste heat from the power plant with the aid of the low-temperature ORC cycle. The ORC system is heated from two heat sources, the first one being the flow rate of waste heat obtained from the exhaust gases.

The Optimal Peak-Adjusting Parameters of Low-Temperature Heat Source Heating
Solar Energy, 2005The integrated low and high temperature heating water system consists of heat pump heat source and boiler heat source. The heat pump heat source abstract heat from low temperature heat source and produce hot water up to 65°C. During mild weather, the 65°C hot water is sufficient for building heating.

Cryogenic refrigeration using a low temperature heat source
Cryogenics, 1981Abstract A non mechanical gas sorption refrigeration system which could be powered by a low temperature heat source was designed and analysed. The system involved no sealing, no mechanical moving parts and no active control. The system was analysed using a 1 W cooling load at 74 K as an example. It was found that the new system was competitive with a

Irreversibility reduction of low-temperature, combustion heat sources
Proceedings of the 24th Intersociety Energy Conversion Engineering Conference, 2003The author discusses a concept that will reduce irreversibilities associated with combustion and, thereby, deliver more heat to a process than the heating value of the fuel. The concept involves the use of staged reactions to facilitate the more reversible reactions associated with the combustion process.

Economy of exploiting heat from low-temperature geothermal sources using a heat pump
Energy and Buildings, 2008The article describes the economy of exploiting heat from low-temperature geothermal sources for high-temperature heating of buildings using a heat pump. For the exploitation of low-temperature geothermal sources, a two stage heat pump with a heat exchanger was planned.
